Linksys Wireless Router :: E4200 Wireless Client Drop On Transferring Data
Dec 14, 2011
I have had an e4200 for about a month now and its been pretty good. But I have noticed that it completely locks up when I go to copy mass amounts of data through it. I have a NAS drive plugged into it and my laptop is on the 2.4 spectrum. I went to transfer 8gigs of data from laptop to NAS drive and the entire wireless portion of the router locks up. All my wireless clients drop and I have to unplug the router and plug it back in. Even the 5ghz clients drop as well. I have not tried hardwire, but the main reason I got this was for its throughput.

I'm pretty new to networking. Purchased a E4200 for my home line. When i connect directly through the modem i see speeds of about 600mbps but when i connect through the router via an ethernet cable on an empty port on the back of my e4200 my speeds drop to about 180mbps. I expected a speed loss going through wireless but why i am experiencing a speed loss by using the ethernet as a passthrough? I thought the ethernet ports on the e4200 were gigabit and support up to 1000mbps?

I have several E4200 routers deployed in our library district. In one branch, we have been having sporadic problems with computers not being able to maintain a connection. Typically the computer will connect and then the connection will drop and Windows will display the yellow error triangle on the wifi signal strength display.I have swapped the router with another brand new E4200 with the latest firmware but am still having this problem.

I have a 1.5 TB USB hard drive attached to me E4200. Configuring it so that multiple computers have access and can read and write their files is quite simple. I've followed the instructions and had no difficulty.
My problem is this, after about a week's time has passed any file that has been on the hard drive for more than a week become undeletable. Any attempt to modify it or remove it pops up a message saying I need permission from a specific user (always the user that I am currently logged in as!) to perform the operation on the file.
When this starts to happen, the device is, otherwise, perfectly functional. I will still be able to create new files and delete any newly created files from the drive without difficulty even when those files are in the same directory as the files that the device will no longer let me edit. Examination of the file properties dialog shows that the files that the device refuses to allow me to delete are identical in every way to any new file that I create. Yet newly created files are removable but these older files ... are not.
I'm quickly coming to the conclusion that the HDD mounting feature of the device just doesn't actually work as advertised.
FWIW: all my computers are using Windows 7 with the latest build. I do access the device from these computers wirelessly.

I have E4200 v1 with 1.0.3 firmware and an old 2.5"/120GB hard drive. Today I discovered that all my data where lost. They were there not longer than a couple of days ago. I'm almost sure it's not my fault and the drive is healty. I'm now moving back datas onto it and I will check for them daily.
1) I had no power loss;
2) I didn't reboot nor I didn't switch it off/on;
3) I didn't copied files since days;
4) The last time I used it I just browsed files;
5) It's not exposed to the internet but just to local network;
6) The router hasn't logged admin logon other than from my computers.

I'm using E4200 (fw 1.0.03) as AP and EDIMAX 6675nD as a client. I can't get over ca 10MB/s data througput even there aren't any other communication loads. Test conditions are: 5GHz band, no other networks in the band, distance 2m without any obstacles, no other data transfers (except the test), data source is NTB on GLAN port of Linksys, data sink is NAS at GLAN port of Edimax, test file is 0.5GB file. The NTB and NAS doesn't seems to be a bottleneck, because NTB connected directly to the Edimax does over 50MB/s. Both the E4200 and 6675nD are (should be) capable of 450Mbit/s @ MCS23. Strange thing is that none of them allows setting of MCS23 in their manual settings. It ends with MCS15. While forcing the E4200 to a specific MCS (in the hidden wireless_advanced menu) the MCS15, 14, 13 and auto give very similar results. The throughput drops by MCS 12 and lower indexed MCSs.The 10 MB/s seems to be a low number.... and (based on internet forums) I'm not the only one fighting the magic number 10MB/s. What is the reason of the ca 10MB/s bottleneck? And the resons why both of the routers are quiet about the MCS16 to 23 schemes in their menus, while their labels aren't?

I have ten E4200 routers deployed in five library branches. In recent months, the E4200's in two branches have occasionally gone into a state where they are not always providing an IP address to both wired and wireless devices. Some devices will get an IP fine and others will not, The problem seems to move and the next day the same device will connect fine and others will not. A reset of the router usually clears the problem but it is becoming more frequent and bothersome. For some reason only two locations are effected.
Some notes:
- Firmware version is 1.0.02 build 13
- When I set devices up with static IP's they work fine, so the problem seems to be related to the DHCP service
- The WAN side of the network tests fine with no issues
- I've had these routers deployed for over a year and this problem just started in the past two months
- Routers and AP's are on different channels to prevent interference
- No nearby WiFi signals appear to be casuing any interference

I've assigned an ip address to my htpc using dhcp reservation. On my old router I could use the client name, for instance: ssh name@clientName Instead of: ssh name@ipAddress Currently I cannot do this with the stock cisco firmware (unless I'm mistaken). Is there something I have to do to get it working? Or do I have to resort to tomatoUSB/WRT.

I just purchased an E4200 router. I have four clients on my network and they are all set up for DHCP. I renewed their IPs and they all are connected. "Cisco Connect" reports that I have four clients connected. When I access the router and bring up the DHCP Client Table, there are no entries. There should be four entries. Aftern I enable the logging function, none of the logs have any data in them even after I wait for 45 minutes and use the internet and renew IPs. I am using Firmware Version: 1.0.03. I have the same results for both Chrome and Firefox. I want to be able to set Static IPs but I am hampered by the not having any clients in the DHCP client table.

When I enable IPv6 on my E4200, the Windows 7 DHCP client crashes. It also seems to crash the audio service, the event logger and a few other windows services.

One of the many things that I liked about the e4200 over my olg 54GL was the fact that I could reboot it remotely. However, I've recently had a few problems that only a full power down would fix. In addition, I've noticed that the DCHP client table doesn't reset when I do a soft reboot. Is this intentional? Is the soft reboot not really a full reboot? Can it be made a real reboot?

Which Intel network cards runs well with E4200 (latest FW)? I mean good connection and transfers rate. I have two clients with the same cards (Intel 4965agn, latest driver) and I got transfer rates at 144 Mbps with both radios working (2.4 and 5GHZ on the E4200). When I try to use 5Ghz only it drops to 54 Mbps and for 2.4Ghz it drops for 130 Mbps. Could I reach better transfers rate with a Intel 4965agn card (300 or 450 Mbps)?

I have a Wrt160n router and a Motorola sb120 modem (provided by comcast after my original modem got fried by lightning, no I didn't have my router hooked up when that happened), I have been having trouble trying to get the modem to send the internet signal to my router. I have tried mac address clone that was suggested on this forum for someone with a different router but still no internet to my computer, its all hooked up through Ethernet cables, the computer I have it hooked up with a hard line is running windows seven. When I plug the modem straight to the computer it works and I have internet but when I hook up the router between them it has no internet.

I got a refurbished EA4500 (directly from Cisco) last week. I have been having a few issues, which I have found (not too great) workarounds for. However, the latest issue has me stumped, and is unacceptable.Whenever I am transferring files between 2 computers, I get kind of OK speed (5 MB/s). However, while this transfer happens, no other device can connect to the net. Actually, even trying to go to router home page (192.168.1.1) times out.The clients still say they are connected to the router, but I just can't get anywhere.As soon as the file transfer finishes, everything goes back to normal.EA4500 replaced a WRT54G. Never had any problems with that router. It was such a workhorse. Just needed to upgrade to a n-router.I am on the latest non-cloud firmware.I have reduced the MTU size to 1200. Not sure that matters.

I have an EA3500 and a Windows Vista PC, connected through wireless. When I transfer data from PC to USB shared storage on the router the speed seems normal while it goes awful when I do the opposite. The average speed goes around 200kb/s to be specific. This is unbelievable as it is year 2013.

I have a router connected ea2700 on the Internet port to a switch se2800.e switch is connected and everything is gigabit nas. if I try to transfer a file from PC, gigabit ethernet, the transfer rate does not exceed 8 MB/s. if I transfer a file from the NAS to the PC speed is 15 MB/s. the support advised me to change MTU manufacturer parameters,to disable protection,and clone the mac address.the situation has not changed.if I configure the router in bridge mode, the speed is 22MB/s and 45MB/s.

I’ve bought a router, and a wireless antenna for my laptop, since I have a high-speed internet outlet in the living room, but I use my laptop in the kitchen (I don’t have any other pc). So I’ve configured my Linksys WRT120N router in the living room, unplugged the ethernet cable from my laptop, plugged the wireless antenna in the kitchen, and everything was working fine with the wireless network. After about one month I was not able anymore to enter my network with the security key, there was actually no prompt for the security key, just a message “Cannot connect to the network”. I then had to reconfigure the router, going to the router IP address (I used the default settings, a blank for username, and “admin” as a password, as per instructions), use another network name, security key and password, and was able to start again a wireless network with the wireless antenna as before. This problem represented other 3 times (in the last 3 months), and was working fine, but now I cannot reconfigure the router anymore, since the IP address doesn’t accept BLANK/ADMIN anymore, and if I go ahead and reconfigure the router a message says I have to use the default settings in the IP address…

I purchased this router a few months ago(wrt54g2 v1.0) when I moved into st louis missouri. My ISP is charter communications. I am using windows 7 64 bit.I had no problems with this router with wired connections, however my wireless devices would drop repeatedly. I updated the firmware to the latest linksys version, but still same issue.After much research online and trying everything I could through linksys, I found a page that someone with the same problem said it could be solved by upgrading to dd-wrt freeware firmware. After much trials and problems, I finally got it installed. However I did not like dd-wrt because it would not allow FTP access no matter what i tried, and would lead to dropouts of wired connetions even though it did fix the wireless.I then decided to revert back to the previous firmware - this is where i think i messed up..I downloaded tftp and a firmware called vxworkskiller, this was supposed to be able to break the dd-wrt firmware which it did, and removed it. I continued to follow the instructions provied to me and was able to then install the linksys firmware but I accidentally upgraded the firmware for the router WRT54GS with the firmware version 7.50.2. This is now dropping both wired and wireless connections VERY frequently. My roomate is not happy as we have to power cycle the modem, router and pc's every couple of hours and sometimes that doesn't even work.I am unable to flash firmware of any version or type anymore, every upgrade fails weither I use the linksys gui, or tftp or any previously working firmware. All fail.

I have 3 devices connected to the e4200v2 via etherent, out of the 3, only my Xbox has drop about every 15-30 minutes. I have tried Cisco customer service 4 times and Xbox customer service 3 times with absolutely no luck. They both tell me that all of my setting are correct and there is nothing more that can be done.
I have tried everything that I can think of: Port triggering, port forwarding, DMZ, UPnP enabled/disable, power cycling everything, putting Xbox as Qos high priority, designating a static IP for the Xbox, clear the Xbox's cache twice, I even formatted my Xbox's hard drive in case of corrupt data. The Xbox does not disconnect when connected directly to the modem, making the router the common denominator. I am on the verge of returning the router.

I purchased a WRT110 router about a 18 months ago. I am currently experiencing an issue where the wireless connection to the router will become randomly erratic. My internet connection will slow down or drop entirely. Sometimes my laptop will disconnect from the router entirely. I don't think it's the wireless card in my laptop since I have seen the issue on my desktop using a wireless N USB adapter, my Nintendo Wii, and my wife's Macbook, all within the last week.
I am positive it is the router. I set up a coninuous ping command to the router accross my laptop's wireless using "ping -t 192.168.2.1" in a command prompt. Most of the time, the round trip is 1 to 3 ms or <1 ms. When I am experiencing the connection issues, the ping time will rise significantly, sometimes going as high as 2000 - 3000 ms. About 25% of time, the ping will just time out. When this starts happening, the only way I have been able to restore proper connectivity is to manually reboot the router. The issue eventually re-appears. Sometimes in a few days, sometimes in as little as five minutes. I've gone so far as to restore the router to factory defaults and reconfigure it, but that has not made a difference.

I have experienced some strange behavior of WiFi connection using WRT320N router. ISP provides me the internet in 2 modes (day and night). During day mode max speed is 24 Mb/s and during night 60 MB/s. Modem ADSL (Cisco EPC3010) is connected to Linksys WRT320N and on router is configured WiFi.Now issue. In the day mode everything is perfect. Cable connection gives me 24 MB/s and WiFi connection around 22 MB/s so not so bad. However when my internet speeds up to 60 Mb/s (cable connection via router gives exactly 60), WiFi connection instead speed up as well, just drop to max 17 Mb/s. I have tied several different settings on the router including changes in WiFi band, channel width, different channels (now channel is setup to 1 which is maybe not totally free but no so occupied) and others but unfortunately without significant improvement (in many cases connection just slowed down more).
And some details:
Wireless configuration (now)
Band: 2.4GHz
Mode: Wireless-N only
Channel Width: Auto (20MHz or 40 MHz)
Channel: 1
Wireless adaptor: Intel Centrino Advanced-N 6230 (I know that this doesn’t mean anything but Win7 shows that connection is established with speed 144MB/s)Router firmware and WiFi card updated to the newest version.

So here's my issue, I just bought this EA4500 so I could use the 5.0 Ghz and get a new 2.4Ghz as my old Netgear would drop the signal on a fairly regular basis. I've set the channel on 2.4 to 1, 20 Mhz Channel, and my neighbors are for the most part using channels 6 and 11 (one guy is using channel 2 at 40Mhz but has a very low signal strength). The signal drops out sometimes as often as every 5 minutes, and now it is doing it on my new router. Here's the kicker, the 2.4 band falls out from my router and some of my neighbor's routers, no new signal seems to come up, but the 5.0 band on the EA4500 is just fine, as is the wired route. Is the 2.4 band just being assaulted at my home and I'll have to deal with it, or is it that my new router, old router, and my neighbor's routers, all suck, and we should all get refunds? Any solutions to troubleshoot this beyond running a netstumbler like software, setting hard channels (including width), and long hours of trial and error? I am running this all from my macbook air, the 5.0Ghz is at 40Mhz, is the only signal, and is on a fixed channel.

After an upgrade of the WRT120N to firmware Ver.1.0.06 (Build 01) every device I have tried to use WPA authentication with will authenticate / associate with the device then drop the connection just prior to recieving a DHCP address.I have tried a Dell latitude laptop with the broadcom chipset, an iPhone 3GS as well as an motorola with google pad device and all experience the same problems.I have removed all mac address filtering, and re-enabled the essid broadcasting only to have the same problem persist despite stripping everything down to just WPA.

I would like to be able to allow a specific client to only associate at 6mbit/s -is this possible using the wlc controller 5508? Another option would be to limit a whole w lan ssid to 6mbit/s but i can't find a way to do that either.
Other w lan ssid's on the same access points/controller need full data rates, so i guess i can't use the RF-profiling for this.

We are currently experiencing random multicast data dropouts on ports that are connected to a 3750X in VLAN ports. A test PC was connected to a routed port and we do not have any dropouts of the multicast data.We also took a 2960G and plugged it into VLAN ports on the 3750X. Any test PC that is on the 2960G does not lose traffic. The traffic only drops on PCs that are connected to a port on the 3750X that is in a VLAN. The data drops are random and last approximatly 55-59 seconds before we start receiving multicast traffic again.
I do not see any input/output errors on the interfacessh platform port-asic stat drop also show no drops
CPU runs at about 50% on the 3750X
Below is the configuration of the 3750X

I've a WRT54GL still working well after 5 years of use. I've got one Ethernet cable attached PC (computer "A"), and two WI-FI attached, (computers "B" and "C"). They're all running Windows XP. I've heard much about how intelligent devices and intelligent systems can route the traffic in the most efficient manner, but not sure how or when it works. For example, if I sit at computer "B": and copy (or move) a file from computer C to computer A, what route does the data take? Does it pass through computer B?

I own a wireless router (ZTE W300) and due to the large number of devices in my house, and limited broadband usage, can I limit downloads/uploads (in other words, limit data usage) to a particular device over the network?I think the stock firmware on my router doesnt allow that (and its pretty base level too). If so, do you recommend any other firmware that can do the task, and is compatible with my router?

I currently have a E3000 router. I have set up a shared USB drive successfully through this router. After a couple of months, I needed to re-locate my router into a different room. After doing so, I plug back in the USB drive and cannot access it. If I go through the GUI, it tells me that the drive type is not supported, and if I just plug it into a computer to obtain the infromation off of it, I get a "drive is corrupted" error

I had my external drive plugged into the e3000 with the network drive mapped on 2 laptops. One day my connection was slow so I backdoored the router ip (I didn't use cisco connect) to reset the router from my iPhone. I'm not sure exactly what was changed, but the partition disappeared from the drive. I've used a couple file recovery programs to try and retrieve the 250+ Gb data that was on the drive with no luck. They only find "deleted" files. Not the 13k files that were there and not deleted. The drive was never bootable. What to be used to recover the files.

I've lost about a TB worth of data. I'm rebuilding a computer and had my hard drive, a Western Digital Caviar Black WD1001FALS 1TB, in an external enclosure so that I could access files from it until I could move them to a new drive. I just happened to hook the drive up to the USB port on my new Linksys EA3500 router and now I can't see anything. I believe the process of plugging the drive in, allowed the router to mess with the partition table of my drive. Before, when things worked I saw three logical drives. one of about 50-75 MB of reserved space. One of about 80 GB that was my original system drive and one of about 920 GB that was my main data drive. All of these were NTFS. Now when I look at the drive, all I see is one drive FAT32 drive of about 71 MB.If I look at the drive under Computer Management, Storage, Disk Management, I see the drive is made up of a 71 MB FAT 32 Primary Partition and a 932 GB Unallocated partition.Am I totally screwed? Is my data still there and is there any way for me to access it or any utilities I can use to get to my data in this unallocated partition? What the heck did this thing do to my drive without permission?

I have been having a lot of trouble lately with my wireless network. Basically, under certain situations it will constantly drop out, by which I mean all computers will lose connection with the wireless network for about 30 seconds and then reconnect.This is happening with two different wireless routers so I don't exactly know what is happening. I usually use a Linksys WRT54GS v7 but after this started happening I borrowed a friend's Linksys WRT54G2 v1 router to test it out with no change. I also updated both router's firmware last week, and changed both router's channels to 1 in case that was a part of the problem. To clarify,only one router is being used at a time, I have just tried different steps with each one.The other day when it was happening repeatedly, I connected one of the computers directly to the modem and had no problems so I do not think it has anything to do with my modem. On the network, depending on the time of day, there will be any combination of three macbooks running the latest version of snow leopard and one older PC running Windows XP. The network can drop out with only the PC, no PC, or any combo of macs. There can also be two iPhones and a Blackberry using the wireless depending on who is home. The most consistent problems seem to occur whenever something is being uploaded. We seem to get major issues when my wife is sending relatively large files (5MB+) using her macbook's mail program (either sending through gmail or her work address). However, yesterday it was happening every 30 seconds when someone was talking on skype on her macbook while there were two other macbooks connected to the network but doing nothing more than using a browser for basics like google.I have also noticed that this will often happen, though usually only once rather than repeatedly, when a computer that hasn't been on is turned on.

My setup is as follows:
Linksys E2500 as DHCP client, all default network settings (MTU auto configured to 1500), connected to:
ZTE 831 II ADSL2+ modem in bridged mode
The issue is that whenever any large file is downloaded over HTTP, the download stops after about 4 minutes and never resumes. This results in:
1) HTTP downloads of anything > ~80 MB failing; tried using several browsers and CURL, all with the same results
2) iOS downloads in iTunes timing out
3) YouTube videos stalling every few minutes
Interestingly, Netflix streaming works OK. Perhaps that's because the protocol for Netflix is not a single large download but a bunch of smaller ones, but that's conjecture.
This all occurs over both wireless and wired connections to the E2500.
If I connect my Mac directly to the ZTE modem, I don't have the problem.

I have WRT160NL with Firmware Version: 1.0.02. After 3 days of trying to connect my WD Elements 3TB I succeeded with 2 partitions of 1TB and one of 700 Gb not visible from router. I'm ok with that. The problem now is when I copy my files. I'm trying to create TV Series library for my Apple TV. Everything is working fine except the size of the files. When I'm copying files from PC USB they are corrupted on the network storage and not accessible. When I'm copying one file of size 350 Mb on the Network Storage via WIFI working fine but is saved with size of 2,7 Gb.
