Linksys Wireless Router :: E4200 Wipes Attached HDD On Power Loss
Dec 18, 2011
I'm loosing about 40GB of data. If worst comes to worst i might go with another brand of router instead as i don't wanna waste a lot of money again as i currently feel i have with the E4200. Enough whining, here is my problem. The FTP and Media Server feature works nicely. I have a 2TB USB 2.0 HDD attached to the router's USB port. I use it for images and my music collection ripped there so i can play it all from my PS3 and TV. I also have many GB of video recordings and converted DVD discs for easier access. (And no, before anyone speaks of piracy, it IS legal, at least in my country, to back up your legit media) Now, everything worked fine, until one day after a few weeks, the router hanged for some reason so i decided to reboot it. To my disappointment it also wiped video and audio from my HDD which really got me pissed as i lost all track of what i had on the HDD. The Media Server was also having connection issues once in a while so i decided to update the firmware from 1.0.00 to 1.0.03. It immediately fixed the connection issues of the Media Server. Another noticeable change is that files transferred via FTP will show immediately via the Media Server without the need to update the database via the router as i needed to do in 1.0.00. Now today there was a power loss in the neighbourhood so the router went dead along with the HDD. To my big disappointment, everything was gone from the HDD when i started it up again. Images, music, video and even my application backups etc. It was just plain empty except for the root folders. I have done a few tests and figured that even if the HDD stays on, cutting the power to the router will wipe the connected HDD. What's up with that? Even a silly Windows PC wont nuke your files that much if an accessed HDD was disconnected while in use. Do i really need a UPS system for the router and safely disconnect the HDD from the router via the user interface every day? If so, the concept of having a router with these nice features is really useless and money theft in my opinion.

well, i just bought an E4200 and, by the way, was very hard to configurate. But the real problem is: if there is a power loss, both modem and e4200 lights up, but no internet connection is provided.Even the SSID desappear. I trried to disconnected everything, reconnect by parts, but no success.I wired connect the E4200 to my iMac and the router was ok, configurated.Then, i reconnect to the modem and all worked ok.Now im testing possibilities and is i reboot the router, the net desappear and i have to try possibilities till it works.
My older router connected automatically, without a problem, but i decide to buy "the best" brand and its top product". Now im disappointed..
Twice i realize that if the connections drops out, i have to disconnect and reconnect the internet cable from my E4200...

I have installed my new E4200 and it works beautifully. I have several wirelss adapters and a few wired connections through powerline adapters. I also have a second VPN router attached to the 4200.I can see the wireless connected devices with the associated IP addresses. If I plug a laptop directly into the Cisco, I can of course see it.However, I can see none of the devices attatched to the powerline devices? I have a securty cam connected via the powerline and want to know the IP address. I checked with cisco technical support via chat and they said it is impossible. I have used 2 previous routers with the same configuration and can see all devices.

I've verified that the router and the pc have the same time zone, daylight savings update specification and that they both showed the same time (00:56AM). But a file created on the attached USB device was timestamped 01:56AM (the date was correct).

I own a CISCO Linksys 3500 router I use in my home. Every time there is a power outage, the router stops working. The only way I have managed to get it to restart is to remove the software, disconnect the router and then re installed and set up the router again

I recently installed some wireless IP cameras and when attempting to re-install a camera I went into the DHCP Client table to verify which IP a camera was using to set it up, but I could not...and still cannot see any of my cameras in the table even though I can access three of them directly through the IE web browser. I initially power cycled both the E4200 router and Motorola cable modem, and then later just the wireless router...but I still do not see the devices connected. I currently have 2.0.37 firmware even though I was told by Cisco support that there was a later version available, just before being informed that I do not have support available and could purchase it. I attempted to locate a newer version, but the online upgrade portion of the Cisco Connect software searched the net and then states that I have the latest version available. I also opened a Firefox browser to see if maybe my browser was causing issues, but the same limited table appears without all entries available. I even opened the Cisco Connect software on another laptop with the same limited results. Other than a factory reset, get me E4200 dual band wireless router to show all attached devices through the DHCP Client table as it previously did approximately two weeks ago?

I seem to be having packet loss with the E4200V2 which is upgraded to the latest firmware as of today, 1/18/12
The application is accessing a security DVR which uses a RTSP / RTP stream. Of course this requires certian ports to be forwarded in order for this to work. This works flawlessly with a WRT310N or a Cisco 871 Router so I know the port forwarding is correct.
With the E4200V2 it works intermittently, I can replace EV4200V2 with either the Cisco 871 or the WRT310N and there are no issues.

So I have an WRVS4400N V2 and just got a new laptop with an Intel 6230 Wifi card in it and have an odd problem.While the laptop is on battery power the network gets massive packet loss.
I don't know what to do.Laptop manufacture says its AP but AP worked fine with old laptop and works fine when laptop is on power and all other devices seem to be fine with the exception of my Xbox 360 that wont connect if I have it on WPA2 but I will post another thread for that.

All of a sudden I started experiencing occasional loss of communication with my router. I tried updating the firmware to the latest (1.0.04) but am still experiencing the same thing.I don't lose internet access, I lose connection to the router itself. If I power cycle the router, the connection is re-established and I'm able to access the router and in turn the internet. I'm seeing this on both wired and wireless connections. Last night the Cisco logo actually turned off when I lost connection (this was a first). When I power cycled, connection was restored and the logo lit up again.

Vista 64 Intel Pro 1000 with latest driver Here is a shot of the lagometer in COD Black Ops when all is good. I used to see this with my old WRT54GS and connected at 100Mbps Full Duplex or Half Duplex and I currently see this when connected through the E4200 at 100Mbps full or half duplex AND when connected via Gigabit via one of the 4 ports on the back of my cable modem, a Motorola SBG6580 [URL] This next screen capture is what happens when I try to connect via Gigabit thru the E4200. It either starts out like this right away or within 30 seconds to a minute this will start to occur. I believe the red spikes indicate packet loss. [URL]

I have a problem with the e4200 router and a mybook 1 TB connected to it. The media server works fine but after a while i loose contact with the router and the server this means that the Cisco connect doesn't work, the 192.168.1.1 doesn't work and I can't find the disk via \. I do have internet connection via wifi as im using it now....why I loose connection to the router? The lease time is 24h and it can happen more than once in a day.

I don't see any setting in the e4200 interface to reduce the transmit power. I only need to cover my small dorm room not the building. A friend has an e1000 and needs to do the same thing.

I'm using Comcast cable with a Linksys WRT4Gs wife router. I live in an older building which loses power for a little while (10 minutes or so) with every big storm. Every time the power comes back the linksys router completely resets...I have to plug into it and change the SSID, turn security back on, enter the password again, and then I'm fine...can I prevent this from happening? Before I plug into it I see both networks available (mine under my name, but I can't connect to it, and linksys as a public network), is there a step I'm missing to make my router remember it's identity?

we have two WLC model 5508 with software version 7.0.116.0 (25 ap supported for each), i tried to add a new access point air-lap1131ag-e-k9 but after five minuts (maximum) the ap reboot, i replaced :
- power injector
- AC/DC adapter
- patch ethernet
- switch port
- switch
- ip of the access point
- reset a default of all access point i tried
- reboot of both wlc
I took the ap and connected directly to the switch (with or without power injector), but the access point reset with this reason.

I'm running Windows 7 Home Premium (64 bit) connected to a Linksys WRT610N Router. I have attached a 320GB USB 5400 rpm hard drive to the router as NAS storage.The router is running 2.00.01 build 15 firmware. I get frequent drop-outs when transferring large files. Tonight I've been trying to transfer a 4.36GB file to the drive from my PC. I've tried several times. At exactly the same time, with about 377MB to transfer I get a message saying 'There is a problem accessing Z: make sure you are connected to the network and try again'.

I am very pleased with my purchase of the E3000 so far. However, one function seems to allude me. One of the main reasons for purchasing this router was because of its Media Server functionality. I wanted to be able to stream to my UPnP devices (ps3, xbox360, etc) without having to keep my power hog of a PC running. I have set up the HD using the Storage tab of the Advanced Router Settings, and created several Shares on the Media Server tab. The good news is that I am able to access the share on my PS3. The bad news is that I can't on my Xbox360s. As the Xbox360s has built in wireless N, I would really like to be able to stream to that system.

I have mapped the attached hard drive to my EA4500 on my PC and can access folders and files on my LAN PC. However, when I come in through the Internet via an iOS device, I can see folders but when I try to enter the folder, all I get is a message that displays "|Folder|Enter Into Folder|Select|. There is no click-through capability other than "Return to Upper Folder", which takes me back to folders.

We installed a new WAP 4401n to extend a network and plugged it into a D-Link mini swtich (5 ports). In about 2 minutes we got no activity on the switch. We pulled power on the mini-switch, waited a couple minutes and re-powewred. No activity. Looks like we blew the switch. Put another mini-switch in and it did the same thing in about 4 minutes.
The WAP4401n is a PoE ready AP. We are checking right now on whether it's a cable wiring problem or an AP problem.I believe we are using the RJ-45 data cable that came with the AP.

I have a switch stack with three WS-C3750X-48 switches running 12.2(55)SE. Recently, stack member 3 went offline for a few minutes, after being online for over a year. A show version on member 3 reports that the system returned to ROM by power-on.
Stack member 3 shares a UPS with a router that did not lose power and all three stack members have stack power with four 350 WATT power supplies between the three of them. There are no crashinfo files on any of the switches, log files show the stack ports on the other switches going offline then switch 3 being removed from the stack.
Surveillance recordings show there was no one near the switch during the time and AAA accounting shows no clues. Is it possible the switch crashed without leaving a trace in the logs, a crashinfo file and report that it returned to ROM by power-on?
I've read before that loose stack cables can cause stack member reboots. Would such an event generate log messages other than the stack ports changing states to down?

We have 2 of the SG200-26 switchs. When ever we loss power all the settings are reset to default. Even if we loss power for 1 min. This includes the IP, user, password, etc. How can I change this so the settings are saved?

My network is a simple Linksys E3200 to broadband modem to Cox Cable ISP. When only one machine is attached, it works fine. When I add any other machine to the network, whether wired or wireless, PC or mac, the connection is dropped. I've updated my IOS, checked access settings, called my ISP. ISP says it has to be a setting in my router.

After setting up the newly arrived router, renaming the SSID and changing password for 2.4 GHZ AND 5 GHZ and also renaming the default router username and password, I decided to update the firmware.The procedure wiped all configuration I've made forcing me to do all over again.

I had to change from a WRT300N wireless router which died to a new E2500. I noticed that the speed my computers report that they are connected to the wireless network connection is now 144.5 mps, versus 270 mps with the WRT300N. There is no change in location of the devices or computers. The computers use a WUSB300N adapter. Is there a setting or setup that needs to be changed?

Having several issues w my E1200. For quite some time I have had intermittent loss of internet connection. This was somewhat true even before I got a wifi router. & it has continued. Recently it has been even worse & I'm not sure if it is my isp, my cable modem or the router. ISP came out & checked & said signals looked ok, although modem is old.Now i find out that the version of Cisco Connect that i had been using is incompatible w Mountain Lion so it won't work now. & newly downloaded dmg files say they are damaged (or that app has been modified or damaged--I'm not in a position to tell which but same results after I downloaded a 2nd time).
I have been having more frequent loss of internet connection at home. & when I click on the wifi icon to check, it shows it looking for networks. Also it has not been uncommon to see that it has switched to my guest network.Why would it switch to my guest network? What is the difference between the 2 besides the fact that I guess the guest network doesn't have access to everything on my regular network (which right now is only my iPhone, but may get wireless printer).Also when it shows the lists of networks that it "sees" my guest network does not show a padlock icon so what does that mean? It does have the default password.
Also because I had no idea that Cisco Connect was not compatible w Mountain Lion I didn't even think to check for upgrades before I upgraded to Mountain Lion & now I can't open Cisco Connect. Shows unsupoprted OS. & I'm also stalled trying to update the firmware for the router.I'm really beginning to see why it was cheaper than an Apple Airport Express. Even at a very low hourly rate, the lost time spent when this has not been working right has not been worth what I saved on the purchase price.

A while ago I bought a WRT320N as a trade-in offer, unfortunately I had around 20% packet loss on my connection after I set it up. If running directly through my cable modem I had no connection issues at all.I was running the whole setup cabled, and have no peripherals using the wireless connection.The router was returned to the retailer for RMA, and in the end I got the purchase credited.My setup ISP: Dansk Kabel TV (danish provider for internet, TV etc.)Modem: Netgear CVD31T DOCSIS 3.0 compliant Cablemodem (I do not have access to the modem, as it is provided by the ISP. I have now bought an E2000, and set it up in the same manner as the previous router.This has returned the same problems I had with my previous router.Updating the firmware didn't make any difference.Using Pingtest.net as my test reference I get results like this.when connected directly to the modem I get 0% packet loss, max 20ms ping and jitter is 2-3ms.Have I been so unlucky to get 2 faulty routers in a row, or could there be some problems with Linksys routers and Netgear?I have unsuccessfully tried switching cables without any change, tried moving the router "far" away from the modem, monitors etc to see if there could be any interference from the wireless.

My wrt110 firmware .05 has been working fine until now. I have a couple of phones, 2 printers, 3 laptops and a wii happily connecting to it. However now when I power on the wireless device, nothing can connect wirelessly. Wired connection is fine, but my wireless network disappears. No device can find the network, although it is there and set up on the admin pages. I pull the power chord out for 30 seconds and try again to get it going again, a bit like trying to start a car. Everntually devices find the network.
On two occasions it has forgotten the wireless settings and restored an open 'linksys' network. It's really infuriating becuase whilst I restore the SSID and use the same key, not all the devices actually recognise it and have to be reconfigured on the devices.
