Linksys Wireless Router :: E1200 Wifi Drops 80% Packets Computers
Apr 9, 2012
Router: E1200 2.0.02 build 3 Feb 15, 2012
These symptoms are stumping me:
WiFi drops 80% packets from new computers (Win7, IPv4 andIPv6 enabled) to reliable internet hosts. WiFi is OK (0% loss) from new computers to E1200 itself (ping E1200 IP address).Old computers, mobile devices, and wired are OK to reliable internet hosts.Basic Wireless Settings are Mixed, Auto Channel Width. Wireless Security is set to WPA2/WPA Mixed Mode. Guest Access enabled.

Router is connected to my ISP with the option Keep alive and redial value of 20 seconds (the lowest i can set). There are two distinct problems: Router drops connections at random intervals. It can happen once a day or several times a day. It always happens overnight (so every morning it isn't connected). This doesn't seem to be related to ISP as direct connection to computer is stable.The Keep alive option isn't working. When it drops connection it isn't trying to re-eastablish it for at least 2 minutes (the longest i have waited so far, 6 times the redial value configured). Producing external traffic (e.g. constant pinging of some host by IP address, refreshing some web page) doesn't work. When i log on to admin console (browser based) simply clicking connect button brings connection back online. I've even been looking at status page constantly refreshing to see if it ever made a single attempt and it appears it didn't.I did my "homework" before posting (upgraded FW to 2.0.02 build 3, finetuned MTU).

Have Win7 and XP systems in my network wire connected to the router. When IP of both systems are not reserved, each computer can see other network computers and devices, five in total.A good thing that both systems get each time same IPs which even got not changed since I upgraded from E1200.When I reserve an IP for each system exactly that they currently have, both systems loose ability to see other network computers. Network shares not affected, I still can remotely access my XP box remotely from my 7 via RDP by computer name. WDTV Live wirelessly connected to the router can get/update its IP address (no connection issues) but same as others cannot see network resources.
Tried different ways, rebooted, finally ended up with device reset pushing the button.The next day I managed to reproduce the issue, but was able to revert by disabling/enabling of DHCP server.Another issue I got with an external HD connected to the router when some files got converted to folders by uTorrent started from that drive.I had to use Unlocker application to be able to delete folders converted. I can just assume that issue because of anonymous access was enabled to the external disk. No problems when same HD connected to PC USB.

I received a Linksys E1200 Wi-Fi Router for Christmas. I inserted the Setup CD into my iMac, running OS X version 10. 8. 2. I clicked on setup and a window opened with the message "Unsupported operating system".At this point I don't plan to use the Wi-Fi for the computer, but I do need to connect the ethernet cable to the router, then to my computer.I will be using Wi-Fi for my iPad. In that case, I have no instructions on how to set up the router for my iPad. Will this Wi-Fi router work or will I need a router compatible with OS X version 10.8.2?

My 1200 v 1.0 was working fine until I tried to link a wireless internet camera. Apparently I screwed something up in the setup such that I've lost my WiFi connection to my laptop and one wireless desktop. Fortunately my wired connection still works. I've carefully tried to restore my system following the online procedure and while the setup looks OK it doesn't link. In the process I have reset the router to the factory setting several times and have installed the latest firmware version. I contacted Linksys support and using remote diagnosis they reached a point where they said that something was wrong with my computer and to investigate further there would be a fee charged. I balked at that since I had tried the setup from several different wired Window 7 and XP computers.

Okay so my friend recently bought a Linksys E1200 Wireless-N Router. We set it up the other day and it all appears to be functioning just fine. The only problem is when we log into her wifi it says "No Internet Access". I'm moderately okay when it comes to computers but not expert and I'm horrible at the whole wifi router thing. Through my laptop I've done a Windows Network Diagnostic to see what was wrong and it says that my "computer is correctly configured but the device or resource (DNS server) is not responding."

I just got an E1200 router and connected wired to my win 7 machine, Im clocking in the single digit ranges (~8 mbs) download but on my dusty old win xp laptop wireless, Im getting 20 mbs (max speed from isp 20 mbs). Wife's Mac laptop wireless, same speed. What is going on? I updated the firmware, tried altering some settings based on other entries here suggested (WPA-personal, channel to "6") but no effect.

I have the E1200 and since I installed this router, the wireless download speed on my iPad and iPhone has been only around 4 to 5 Mbps when my other wireless devices could get to 7 Mbps and ethernet gives close to 10 (my ISP gives 10 Mbps max).I know many people experience slow download and normally disabling the WMM would solve the issue. But this doesn't work for me and I've made sure i'm on the latest firmware.

For some reason I can no longer make Wi-Fi calls with my E1200 router. I have checked with my ISP and T-mobil. They both tell me that everything on their respective ends is working correctly. The only piece of the equation is the router.

The wireless router, which is a linksys E1200 is completely new. I setup the entire wireless and there was no problems on that front.The problem is the wireless connection. Even when I am within a few inches of the router, I couldn't even load a youtube video properly. It buffers every 2 seconds. But when I plug the cable into my computer, it works completely fine. The signal strength is excellent all the time.
I tried using inSSIDer to look for the number of connections within my area for the one with the least inteference and found that I'm already on the good one, or actually, all of them looked more or less the same. But I tried changing anyways from 1 to 6 to 11, and none of them made a difference.I then tried changing my Wireless Security to WPA2 Personal. Then I tried changing the Wireless Network Mode to Wireless-G Only instead of Mixed and the wireless speed increased.

I recently purchased an E1200 to replace a broken router. I have had good experiences with this model in the past which is why I bought it. However this has not been so pleasant. For some reason the internet connection over wifi is INCREDIBLY slow. I don't know why. It is fast when connected via ethernet to the router. I changed the MTU on the router to 1400, I set the wireless width to 20MHz and the channel to 11. I set security to WPA2. And yet it is still very very slow. It's not a matter of how many users are on the network; I live in a house with five other people and it's slow regardless of whether everybody's home or nobody is home. It's like this on Macs, PCs, phones and even the Xbox 360. I just did a speed test. Wired was about 14MBps down, wireless was around .7MBps down. I simply cannot comprehend this discrepancy. The old router was very unreliable in terms of connectivity but at least it was always fast. And my laptop is fast at my mom's house where she has an E1200. I use a MacBook Pro from 2009 but like I said,this seems to be affecting everybody in the house regardless of hardware.The modem is a Ubee modem from Comcast. I'd upgrade it to a SURFBoard but my landlord controls all the utilities and I'd rather not have to explain to him how to call Comcast and tell them to register the modem's serial number to the account or whatever.

I just bought the Cisco E1200 about two weeks ago to replace an older Linksys non wireless router. With my old Linksys, I had an Acess Point installed, a trendnet TEW-638APB. Now that I have the new Cisco E1200 which itself is wireless, I'd like to add my TrendNet Access Point to the netowork and extend the wireless range. However the place in the house I want to put it does not have any CAT-5 cable running to it so I'm trying to set up a bridged connection between the two. I'm a bit new to netoworking stuff but I catch on pretty quick. I've been doing research on it all day between the TrendNet AP and the Cisco E1200 but I'm still a little lost. I've got WDS enabled on the TrendNet AP and have the first MAC address set to the Wireless MAC address of the E1200 but I don't get what to make the next three MAC address. Somone told me to make all 3 of them 00:00:00:00:00:00. Is that correct?
I also have both the E1200 and the TrendNet AP set to the same channel, both are on a 20Mhz channel width, Both have the same SSID though I'm pretty sure that doesn't matter in the long run from what I've read. Also, no incryption on either (no need for it out here).So I guess I'm just wondering how do I use the E1200 as a Wireless Base Station? If that's what it's called? I have upgraded the firmware of the E1200 from 1.0.00 to 1.0.03 but that didn't change anything in regards to seeing an option for a bridging mode or anything. Other than that I'm not sure what else to do.

I have an E1200 model 1 router. I've owned it for over a year and it's given me no problems until now...Hardwired ethernet connections work fine, but the wifi no longer works consistently. I have several wireless-N wifi devices that either cannot connect to the router at all (they present an error message), or do connect but will not load anything over the connection, or will load web pages very very slowly and then suddenly drop the connection.When I go to the DCHP client table, I see all of my ethernet connections but it does not show any wifi devices, even if the WiFi device is showing a connection to the router.The wifi connection is secured via WPA2 Personal.I have tried changing channels to one that was not congested with any other nearby routers. I have also tried a 30-30-30 factory reset. I am updated to the latest firmware version (1.0.03). I am sure I am entering the correct pass phrase to connect over WPA2. All of my wifi devices are confirmed to be wireless-n, not g or b.

We have a Linksys E1200 modem and I have been having problems with keeping my son from using the wireless interenet. I did change the password and that worked for about 24 hours and then he was able to get onto it again. He has a nintendo dsi and he is smart enough to figure out how to dismantle any parental controls on his gaming device. I think that he resets the modem in order to get back onto the internet in order to use his gaming device. Someone told me that you can register each item individually in order to keep kids from using it but I have no idea as to how this works. We have two iphones, a lap top, and two tablets.

My newly installed E1200 only sends speeds of about 16 mbps wireless, but sends the ful 60 mpbs when wired. What is going on. Firmware is up to date. Changing the channels didn't do anything. Is there a way to figure out if the problem is with my laptops wireless card.

I have used our home network with an apple iOS baby monitor app for a year without issues. An iPod is the transmitter and broadcasts the signal on my home network. Any other iOS device can pick up the signal when on "receiver" mode. This app worked great for over a year, but recently the app drops out after 1-3 hours. The dropped device also cannot get to the internet via Safari or communicate via the app. The WRT160Nv2 router indicates that the devices are still connected and the iOS devices indicate they are still connected, but they cannot communicate.
To fix the issue, I simply toggle the unit to/from airplane mode. This disables/enables the wifi and the unit jumps right back on the network and all is well. This is a pain though when the baby monitor drops in the middle of the night and we have to walk to the baby's room.
I have tried to recreate the issue with other video steaming (iphone video to appleTV), but I have not found the issue with any other app. Maybe I just have not run the movie long enough (3 hours+) like I do with the baby monitor app at night. Are there any wifi router timing or other settings that could cause something like this?
I continue to try to trouble shoot this:
1. wifi router issue
2. iOS issue
3. baby monitor app issue

I have a WRT310N V2 wireless router, with a WMP600N dual-band PCI card in my computer, using Vista 64x. I have had the same set-up for the past year or so, even after moving to a new apt, which I have been in now for 3 months. It has worked perfectly, up till recently. Over the past week however, my router has been dropping the connection, to the point of having to wait for it to show back up in my connections list. I made no changes to my setup, prior to the problems. I am kind of doubting it's my wireless card, as I can still see other routers. I have tried changing the MTU size, the Threshold, made sure the firmware was up to date, etc. I re-installed the drivers for my NIC and even changed ports, just to be on the safe side. I don't know what else to do, except go out and get another router. I have to use wireless, as I have nowhere to run cables at. I had this problem before with a Linksys wireless router, but figured it was due to the extreme amount of bandwidth my game uses online. Ironically, both routers are doing the same thing. They hit lag every 60 seconds almost on the money. I'm a gamer, so this is a huge inconvenience for me.

This is another E3000 "connection drops" thread. Some background: I have two E3000's that are cascaded. The main router is in my basement connected to my cable modem and is my DHCP server. The second one is on the main floor and provides my wireless signal (no DHCP, and is hard connected to the main router).I have lots of connection drops with the wireless router on the main floor. Lately I have noticed a trend, though. My connection drops mostly when I browse my network (usually browsing pictures on another computer) or when large files or videos are being transferred. If I connect a cable, I have no problems. When wireless, I have signal drops.I have tried every trick and tip that I've seen on this forum or been provided in the Linksys FAQ. I've changed the beacon interval, fragmentation threshold to 2306 and CTS to 2307, I've tried changing channels, I've checked and unchecked boxes for NAT, Filters, etc. I've tried different combinations of WPA2 passwords. I've tried dynamic routing, static routing, blah blah blah...
When I set the 5Ghz channel to Auto(DFS) it defaults to channel 36 and 144Mbps. When I use other channels, I get 300Mbps. Either way, my connections still drops.
I have the latest firmware 1.0.04 Build 6.I even have the router sitting on top of a laptop cooling pad to keep it cool.No matter what I do, as soon as I start browsing my network the wireless connection drops.I am so frustrated! I upgraded my WRT-160N to this E-300 router to get the faster speed and dual band but have had nothing but trouble. I never had a connection drop with my 160N.
EDIT: I notice that when my signal drops, I can see the power LED blinking on the router, like it's going through a reboot cycle.

I've been experiencing a strange, repeatable behavior with my Linksys E1000. I have several wireless and wired devices connected to my E1000:
Wired: TivoHD, Sony BluRay Player, Sony TV, Windows XP Wireless: Lenovo Laptop (Windows 7), HP Laptop (Windows 7), 3 iPods, 2 iPhones
When I try to copy large files (~ 4GB) from my (wired) Windows XP box to either of my (wireless) laptops, the Linksys drops my WiFi network -- but the wired connections continue to work (including internet access). Copying the same/similar file from a WiFi device to a wired device appears to work correctly, as does copying from WiFi to WiFi.
To be clear, my WiFi network "disappears" -- it is no longer listed as an available network (as opposed to just dropping internet connectivity for WiFi). Unplugging the router and plugging it back in brings my WiFi network back up.
I have been able to repeat this issue with multiple files over the course of several weeks, and it happens about 75% of the time (i.e., I am occassionally able to complete a file copy from wired LAN to WiFi).
A little bit of background: I resurrected an old Windows XP box and am using it for shared network storage. I copied about 400 GB of files from my laptops to the XP box (WiFi to wired) with no issues at all. Pulling the same files back from XP to my laptops (wired to WiFi) has been causing the issue described above.

I have deployed a cisco 2504 wireless controller along with four (04) lightweight access points (1041N) in four floors respectivly. The clients connect to the AP which is deployed in the lowest floor have regular timeouts/packet drops. Further this particular ap operates at channel 11 and it has around 11-13 rough access points in the same area and operates in channels such as 1,3,6,9,11. The DCA (dynamic channel allocation) is set to auto in the WLC. Further each ap has maximum of 07 -10 clients at any given time and I have changed this particular ap and checked still the result is same hence there is nothing wrong with the ap.

My config:
Windows 7 host
MS Loopback Adapter with ICS
GNS3
ASA 8.42 with ASDM 6.4
Vmware Workstation 7 with Windows XP SP3 vm
All are working like a charm, from my virtual XP machine I can ping every site, e.g. www.google.com which replies nice with it's ip-address.
However, I cannot reach ANY website
When I connect through a Cisco 3700 router the webbrowser works perfect, so it must be something in the ASA configuration (I presume )
I've tried about all possible Access Rules, but still nothing.

why the QoS deployment causes ports on 2960 switches to drop packets although there is no bandwidth contension? (output bit/second of the interface)packet drops at threshold 1, queue 2 ( queue 3 in config)
We are using Catalyst 2960 switches and are experiencing issues with QoS. After the QoS, we experience a lot of packet drops and it make the network slow. It appears that the slow performance relates to the egress queuing of each port.

I'm using a Catalyst 4948. It seems to drop all truncated packets. I don't know whether this is an expected behavior.I'm developing a program which processes packets in the following steps:
1) capture packets
2) if a packet is too long, truncate it to a certain length
3) insert a vlan tag (say 100) to each packet
4) send them to the switch
Mac address learning is disabled on the vlan 100, so the packets should be seen at all ports of the vlan. However, I only observed untruncated packets. Truncated packets seemed to be dropped by the switch.The summary of the source port is:
c4948-01#show interfaces gigabitEthernet 1/22 summary
......
Interface IHQ IQD OHQ OQD RXBS RXPS TXBS TXPS TRTL
-------------------------------------------------------------------------
* GigabitEthernet1/22 0 0 0 0 4018000 7390 2000 3 0
The receiving speed was approximately equal to what I sent.The summary of another vlan 100 port is:
c4948-01#show interfaces gigabitEthernet 1/18 summary
......
Interface IHQ IQD OHQ OQD RXBS RXPS TXBS TXPS TRTL
-------------------------------------------------------------------------
* GigabitEthernet1/18 0 0 0 0 0 0 3000 4 0
Almost no packets were output.I see a Cisco document says "ingress port drops corrupted packets" [URL] then my questions are:
1) Is this the root cause of dropping truncated packets?
2) What criteria does a switch use to check corrupted packets? My understanding is that truncated packets could have wrong L3 and L4 data, but they can't be detected at L2.
3) If switch drops mal-format packets, can we disable this feature?

I occassionally see an issue on my network wherein a few of my devices (my phone, my wife's iPod, and my Ethernet-connected HTPC) will continually return a bad username/password combo when accessing services like Gmail (IMAP/Exchange), Pandora (HTTPS), or Boxee (HTTPS). The seem to have problems at the same time, which makes me think they are doing this as a result of something failing on my router (and yes, I'm certain the saved passwords are all correct since I won't change them and they'll start working again later).
Whenever the problem occurs, I'm making sure the date/time are right on my devices (i.e. certificate validity dates) and that they all sill have normal internet access. If I had to speculate, I'd guess this problem his happening when my router is under significant load and it's dropping some SSL packets.
I'm running the Linksys WRT310N v2 with firmware 2.0.0. I see there's an updated firmware available (2.0.1), but haven't yet applied it - and the release notes don't speak to my problem at all. I've rebooted the router after the last occurrence

I purchased E1200 and have a problem. I have static external IP but router configured to get IP automatically (reservation from ISP). When some one at home using internet I can commetc to the router using remote management. But when everybody out and no internet users at home I cannot connect to the router. I checked with other router from linksys (old one WAG45G or something like this) and it was the same. But it works great whith TP-Link routers.
