WRT120N - Dropping wired connection frequently

Today alone I have dropped connection 6 times. I recently purchased this router because I thought my WRT54G was kicking on its last leg. It would dropped connections every 45 minutes it seemed.
Now I am experiencing the same issues with this router which is brand new. I have tried power cycling the modem and router. I have made new cables for my devices I am connecting (PS3, PC, DirecTV receiver) I haven't tested things with just going with the modem seperately for security reasons, but I have contacted my ISP to see if anything was wrong with the modem. They have told me that nothing is showing up on there end.
What else could be causing this?

I changed the setting and I am still getting drops in connections while on the internet and PS3. Since the morning of the 9/10/09 up until today, I have dropped 14 connections. Though they only last maybe a second or two, it is still inconvinient.
This happened frequently while trying to play my PS3 online, so I disconnected from the router and plugged the PS3 straight into the modem. I didnt have any issues while playing my PS3. I plugged the modem back into the router and got on the computer for a few hours and the dropped connections started again.
I am honestly at a lost with this.

WRT%$G dropping wired connect frequently

Trying to setup a wireless internet with WRT54G v.3 ( using latest firmware 4.2.1 1/30/2007) on Comcast IP w/VOIP modem (Arris TM502G). Seems to work fine when using only MAC address specific. However when adding WEP encyyption, it frequently drop the wired connection. Sometimes the drop is momentary and it reconnects itself. Other times, I have to restart the router. I've been through much of the forums and have spent much too much time on the issue. Problem remains. Currently using borrowed Actiontec MA424WR without issue. Please help would like to get the WRT going so I can return the Actiontec. Thought maybe your technical crew will have an answer for me...thanks Paul

I assume you mean you are using 4.21.1 firmware.
After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you have not done this since the last firmware upgrade, then please do it now and see if it corrects your problem. If you saved a router configuration file, DO NOT use it.
Also, many users have found that WPA works better than WEP. Please try WPA encryption.

E4200v2 dropping wired connections

I just installed a brand new e4200 replacing my WRT54.
Wireless works good with a noticable performance improvement over my old wireless.
However, the wired conenctions are not solid at all. I am getting over 10% packet loss from the wired conenctions.
I can not even connecct to the web ui reliably over wired connections.
I upgraded to the latest firmware release with no real change at all.
I hope this is an easy fix since the e4200 generally has good reviews Im stumped as to what is going on.

Try the following steps:
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
1] Open the software and go to the option which says "Router Settings"
2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
3] Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page)
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the user name field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.
Then check the connectivity..

Desktops dropping wired connection to e4200 and other Linksys routers

Hi,
On Friday, I lost all Internet connnecitivity on my Linksys e3000. After determining that my cable modem was connected and working correctly, I pulled the e3000 and put my old wrv54g router in place. Wireless worked, but all wired connections showed link but no other apparent connectivity. Neither of my desktops could get a DHCP lease.
At that point, I purchased and manually installed a new e4200 router. All worked fine. Both laptops connected via wireless and both desktops via my house LAN. Until this morning (Monday). Wireless is working just fine, but both wired computers show 100 Mbs connections on an unknown network with no DHCP. Checking status shows packets going out, but nothing coming in. Checking LAN status on the router shows that both ports are connected, but it does not appear to receive anything from either desktop. All was fine last night. Oh, the router is on 1.0.03 firmware.
I have tried about everything I can think of. Configurations both on the router and the desktops (one Windows XP, 64 bit and one Windows 7) and all seems fine. I have disabled and reenabled the network connectors, rebooted both the router and the computers, etc. Nothing seems to work.
I am out of ideas and desparate. Does anyone have any idesa.
Thanks,
Mitch

I actually solved the problem, after a long day of trying everything I could think of, and the issue was not the router. I did a chat session with a Linksys support rep and we figured out that the router was bad. I replaced it with a new one and still had the same problem.
Long story short, I have a weather unit that connects, via wire, to the Internet to retrieve weather forecasts. It is hooked up through a ethernet switch, along with my desktop. For whatever reason, it went flakey and took down everything that was on a wire, including my wife's desktop in another room, which was connected to the router through a hub. As soon as I pulled the power on the weather device, everything started working. When I put power back, everything still worked.
Not sure why, or how this happened, but I will take success any way I can get it.
In regards to the e3000 problem, when I was returing the original e4200 for replacement at Best Buy, the guy there said that they had seen the ethernet switch part of the e3000 units fail before. I had an e3000, which failed last Friday, which was why I purchased the e4200 to replace it. Of course, my e3000 failed completely, including wireless.

WRT120N dropping wireless connection

My complaint is directly toward no one except Linksys/Cisco. I'm sure you've heard this scenario before... I've always bought Linksys products, and picked this router up for my Dad's house because I am staying there temporarily until I find my own place. Router setup like a charm, no issues, and I was very impressed by how simple the company had made things. I have my old man's desktop hard wired in port 1, and use the wireless for my laptop and iPhone. Everything works fine, when the wireless is still connected. I have researched over and over online, and even users have tried to get an answer on this forum without any luck. I have changed all the suggested settings, taken my security completely off the device, and even turned off the "smart wifi" hoping that my devices would just stay connected. Let me point out, the PC that is hard wired NEVER loses connectivity, so that eliminates any questions about the ISP or modem. Also, even though the connection is lost, the router is still visible to all my devices...but can not connect. This is a WIRELESS problem with the DEVICE itself... I've been battling this problem for two months now, coming home, finding my wireless dropped again...I'm sick and tired of power cycling the **bleep** device everyday. This is a very frustrating ordeal for several people, so can we please find a fix? Respectfully, Chris_WV
(Mod note: Edited for guideline compliance.)

OK, so you're not going to answer any of my questions to help you. So let's take a blind stab here.
First make sure your router is on firmware version 1.0.05 (Build 03). If not upgrade your firmware per the instructions on the web site. When successful reset the router by holding the reset button for 30 seconds and release. Wait 10 seconds and power cycle the router. Connect via wired computer to 192.168.1.1 username blank, password 'admin'. Reconfigure the router from scratch (no backup files) and do NOT use the setup CD.
In the router:
Disable UPnP. Under wireless settings Beacon interval 75, RTS and Fragmentation threshold 2304. Select channel 1 or 11. Save settings. Now connect and try.
Further help is to optimize your MTU value. Go here http://www.dslreports.com/faq/5793 to set this in the router. Last thing is if you have any wireless computers on Vista or Win 7 disable IPv6 under the LAN settings for both the wired and wireless adapters. Reboot computers and try again.

EA 3500 dropping wired connection when online gaming

I just had Comcast setup my internet and it is really fast. 30 down, 10 up, 40 ping, my connection to my computer (wireless) is very fast and my online gaming (wired) is not laggy at all.
The problem lies with the connection dropping when I am online gaming. I connected directly to the modem and there's no problem at all. I connect to my Linksys EA3500 and once I start playing in an online game, I disconnect from Xbox Live and am dropped from the game... anywhere from right away until about 10-15 minutes into the game. This is the only time where my connection falters at all, otherwise it is great. But I play online a lot, and competitively, so I obviously need a stable connection.
I have not had this issue with my previous ISP in New York, Time Warner and that connection was much worse. I'm thinking it must be a setting on the router that is causing this, but I can't pinpoint what. I tried automatic AND static connections from my xbox to the router. On the static connection, I even put a DMZ on it, but to no avail. What is causing this hiccup in the connection?
Any suggestions would be great, please and thanks!!

Are you already using the Linksys Smart Wifi? Set up media prioritization in the router and see if that will improve the connection with the xbox. Is the connection intermittent with other devices? Is there like a specific time in the day where your connection will drop?

WRT150N - Dropping wired connection

As the title states I have a WRT150N router. Ever since I've gotten it I randomly lose my connectivity to my internet, and my home network as well I think. My dad has a regular wired router, not sure which one exactly, but when I'm connected to his router I never had this problem. The IPs for all of the computers on the networks are allocated dynamically and aside from that I don't know what could be causing it. Any ideas?

When you lose the internet connection, check if you lose the network connection as well...
The box said windows xp or better... So I installed Linux!

WRT55AG router dropping wired connection during setup

Hi, I bought a Linksys WRT55AG router yesterday after my Netgear wireless router gave up on me.
However, when I am setting up the router with the setup cd, it gets to around step 8 when it is searching for the router, but it keeps flashing that the network cable is unplugged, then it will connect, then it will unplug again. This keeps happening, so I am unable to get anywhere with the setup. It appears that the router is resetting itself as the lights all go off when it says it has been unplugged.
I know there is nothing wrong with the network cable or network card I am using, as I can connect directly to my modem without any problems.
This is really frustrating because I cannot easily access the internet without a wireless connection, and the router is brand new!
Please can somebody help before I pull all my hair out? I can't update the firmware either as I can't keep a good enough connection on the router to do that. Is my router faulty, should I send it back?
Thanks
Rob

i see. if after trying to use another power adapter, and then you have the same problem, try resetting the router by pressing and holding down the reset button for 30 seconds then power off the router for 30 secs and power it back on.
If you still have the same problem, you will need to reflash the Firmware of the router.
go to this link and it will guide you thru the process.:
How to Upgrade the Firmware on a Linksys Router
then, after reflashing or upgrading the firmware, reset the router again for 15 secs then, reconfigure it again.
okies?
hope that will help.

Since upgrading to Yosemite I am getting frequently "safari can't open the page (blank) because the server unexpectedly dropped the connection this sometimes occurs when the server is busy. wait and then try again"

Since upgrading to Yosemite on my iMac I am frequently getting "safari can't open the page (blank) because the server unexpectedly dropped the connection this sometimes occurs when the server is busy. wait and then try again". This is with both a WiFi and Ethernet connection. The server is working fine from other devices using WiFi onto it such as iPhones, iPads, MacBook (which is also on Yosemite) so don't believe its an issue with the server.
I am also noticing page load very slowly when this problem is not occurring.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

MacBook Air + Time Capsule frequently dropping internet connection

I too have been having frequently dropped wireless connections between my MacBook Air (MBA) and my Time Capsule(TC). My TC is connected to a cable modem and I also have an Airport Extreme Base Station (AEBS) at a different part of my house which is used to extend my network connecting via ethernet to a PC running VISTA, and wirelessly to a printer and an older MacBook. I also connect wirelessly to my home network with two iPhones, a Squeezebox 3 with a server running on the PC. I have an Apple TV and a Squeezebox 2 connected to my TC via ethernet.
When my connection drops I will either see a Time Capsule disconnect message or if I am surfing the web, the browser just hangs. The wireless ICON strength is still pegged a the max level. None of my other devices (wireless or ethernet) connected to the TC or the other AEBS seem to drop their internet connections. I can re-establish the connection on my MBA by either turning off my MBA's Airport wireless and then turning it back on or by running the network diagnostics. The latter method usually shows green lights for all but the "Internet" and the "Server" which will have yellow lights. Usually when I select my wireless network and press continue, it will prompt for my WPA2 password which I have to reenter even though I always check the box for it to remember the password in the keychain.
After reading the various discussions on disconnect problems and trying the various "solutions" I was still having the disconnect problem.
Last night, I decided to turn off my Time Capsule and was then able to maintain an internet connection for considerably longer than before. Perhaps it was one of the other "solutions" that caused that. After turning my TC back on, the disconnect problem reoccurred within about 5 minutes.
Next, I did my too frequent Time Capsule remedy which was to disconnect the power and then reconnect the power. (Seems like some of these devices (APPLE TV included) could use power switches.) I then deleted the .sparsebundle backup file on the Time Capsule. I was then able to restart Time Capsule backup and things have been running uninterrupted for over 12 hours...still backing up (20GB in 12 hours? Doesn't seem very fast!). I can report back later if this actually "fixes" my disconnect problems in the future. I am dubious that it will.
I have several questions about the MBA and the TC/Time Machine backup operation.
1.) I often forget about the TC when I close the lid on my MBA and haul it off to work. At work (connecting via ethernet), I will eventually get a TC disconnect error. But I am wondering if there are points in the backup process where a random disconnect will cause some sort of TC corruption. What is the recommended way of handling this? Should I always stop the Time Machine backup before turning off my MBA? (A nuisance if so!)
2.) What is happening when the TC backup operation stops functioning and hangs up the MBA's internet connection? (I see lots of messages logged in the system log when this happens; but, of course, I don't have much of a clue of which ones are normal and which are not normal. I could send a copy of the logs when it happens next (I am assuming it will).
Also one other anecdote. A few months back, I had taken another AEBS to my work to use during a training conference. My MBA kept dropping its connection while the other PC laptops in the room maintained their connections...(very embarrassing!). Maybe one of the other "solutions" would have fixed the problem or maybe if I had just turned off my Time Machine backup it would not have disconnected. I will repeat that exercise when I get a chance now that I have some things to try.
It seems pretty clear to me from my own experiences and the discussion reports of others that the disconnect problem lies in the MBA's wireless internet connection software or the configuration of it. It seems like it is having difficulty recovering from various wireless connection "mishaps".

Folks, I was having a very similar problem for the last 6 months. My connection was fine until June 2008, after which my Macbook and my Time Capsule would constantly conflict. If I rebooted or reset the TC, or the MB, things would be fine for a few minutes or sometimes a few hours and the problem would recur soon thereafter. About a month ago, I had to do a clean reinstall and the problem vanished for about 5 days, after which it reappeared. My MB never had a problem at work, or at someone else's home or with other routers, only with TC. Apple sent me a new TC, then they replaced my Airport card but the situation did not change ... UNTIL ABOUT AN HOUR AGO.
An hour ago, I called Apple for the nth time in the last 6 months, and the rep heard me out (just like the previous n-1 reps). He then asked me to to System Preferences --> Accounts --> Login Items and asked if Real Player Downloader showed up in my list. Indeed it did. He asked me to remove it, and told me that Apple had just figured out that the Real Player downloader was recently found to be causing a drop in the connection between Macbooks and the TC (as well Airport Express).
The problem I've been having baffled everyone. All the previous reps, the guys at the Genius Bars, nobody had a clue. Joe (the rep I spoke with this morning) seemed very confident that the removal of the Real Player Downloader from the list of login items would resolve the problem. So far, so good. My connection seems solid (its only been an hour, but earlier it would drop after 5 minutes of use).
I hope my problem that (literally!) used up hundreds of hours of my time has been finally resolved. I hope this solution will work for at least some of you as well. What gives me hope is that this solution is logically consistent with the history of my problems. I probably first downloaded Real Player in June 2008. And when I did a clean install, I remember downloading Real Player a few days after the reinstall. So I'm pretty hopeful that my issue has been finally resolved.
Shame on Real Player for putting out a defective piece of software. And thank you Joe!

Actiontec MI424WR dropping wireless connection intermittently; wired connection works

I've had this router for about two years, with no issues.
Beginning on Saturday, our two laptops and phones began losing their connection to our wireless network, dropping the signal every 30 seconds or so. I tested the wired connection by plugging the laptops directly into the router, and both computers functioned properly - no issues connecting or staying connected. I have my Roku hard-wired to the router, and that also has had no issue, so it'd definitely a problem with the wireless signal to my devices.
Spoke to a CS rep, who had me first check the internet signal (green, blinking sporadically, which I was told indicated no issue with the connection), then had me reset the router and unplug. No dice. She said the internet signal seemed fine, and that "everything looked good on her end", whatever that means. They're sending a new router which I'll receive today or tomorrow, but I have trepidation.
Has anyone else had this issue? I saw alot of router issues on the forums, but wasn't sure if everyone was having this specific problem (just wireless connect issues).
Solved!
Go to Solution.

This turns out to be good advice. I changed the channel on my router settings to 11 (per an earlier post on a different thread), and I haven't had an issue since. Here's the original post: "01-21-2011 11:32 AM that type of problem doesn't sound like a router issue, but instead sounds like a wireless transmission issue. you may be able to resolve that fairly easily.. Try to change the wireless signal. you can do that in the router. open a browser, and go to http://192.168.1.1, user name is admin. and the password is most likely the serial number found on the service tag of your VZ router unless you changed it. Once you login successfully, go to the top and hit wireless, then on the left basic security. then go to option 3 which is channel 1, 6 and 11 and are the only channels you should try. So it will likely be set to auto, change it to 11 and put the check for keep settings even after reboot (Directly under the channel) and then hit apply., after you hit apply, test your connection out, if you notice a difference, leave it like that until the problem happens again, and if it happens again, go back into the router, and try channel 6, test it out. and then finally 1 if the first two don't work."

BT Homehub 2.0 Dropping all connections. Wired and...

Hi All
I recently joined BT a couple of months ago after being with Virgin. I was very happy with the speeds up the service to begin. Then the homehub started dropping all connections, both wireless and wired. This would happen about once or twice per day and the only way to get the connections back would be to power off the homehub. The lights remained all blue and there was no apparently connection issues after ringing through to support. After a few calls to BT they agreed that the router was faulty.
I then received a replacement hub, and after connecting it, I found that it was even worse. It lost all connections about every 20 minutes to the point where I had to hook up the one I was about to return to BT.
I have read similar threads, but nothing has been able to solve my problem. I have checked the channels and tried changing them, although I was the only router on a particular channel to begin with.
I am about to ring up BT tomorrow to request yet another homehub. Before I do I was hoping that someone would be able to help. In the entire time I was with Virgin for 2 years, I think I lost connection maybe 2 or 3 times over 2 years with their supplied netgear router. This is why I really feel the fault is with the router and not the line. I am not against just buying a new router, so any suggestions that people have used with BT would also help.
See below for my router ADSL settings and also speed test results.

E4200 dropping wired/wireless internet connections

I bought it a few years ago and it's ran fine since. I have been pretty impressed with it up until a few months ago when it started misbehaving (dropping connections every 10 minutes or so). I do have the Cisco Connect software installed and have also been using it.
I thought maybe it's the firmware so I updated after the problems began.
-checked my modem which is fine and is working well within the spec range.
I have done the following:
-I have upgraded to the latest firmware, refreshed it multiple times using different browsers (IE, Chrome)
-changed my settings more than a dozen times (channels and 20 vs 40 mhz)
-removed wifi-protect, put it back a dozen times or so
-did a full reset
-turned it over, on it's side, on it's back
-Did a rain dance but all that did was make it rain
-changed cables three times
It has been in the exact same location near the exact same modem and Ooma box forever. Even my hard wired connection drops every ten minutes or so.
I am desperately looking for some kind of solution to this thing as we have weened ourselves (a family of four) of of cable and rely on it.
I would call customer support but after waiting long enough, I know I'd lose connection again.
Would anyone be willing to offer me some advice or potential ixes that I may have skipped? I really appreciate the effort and hope it can be fixed instead of buying another.
Thank you in advance.

To safely update FW, I recommend doing the following: Download the FW file from the support site first.
1. Save router config to file first using IE or FF with all security add-ons disabled.
2. Factory reset the router with all other devices disconnected or turned OFF accept for 1 wired PC.
3. Reload or Update the FW using IE or FF. Just download the FW file to your local wired LAN PC.
4. Factory reset the router and then set up from scratch first and test with out loading the saved config from file. Check to see if any problems are fixed before loading the saved config from file. Sometimes you need to set up from scratch with out loading the saved config file. Just safer that way.
Internet Service Provider and Modem Configurations
What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
What ISP Modem service link speeds UP and Down do you have?
Check cable between Modem and Router, swap out to be sure. Link>http://en.wikipedia.org/wiki/CAT6 is recommended.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.

For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. Ensure modem is working well too. Bad modems are out there as well. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

Mac Mini drops WIRED internet connection

Hi Folks,
I have a Mac Mini that keeps dropping it's internet connection every couple of hours. I have tried a couple of different routers and am now using the airport extreme N router which I purchased a couple of days ago but to no avail. Other computers on my network stay connected without any issues, its only the mac mini that keeps doing this and not in any particular pattern. This is with a WIRED connection to the router. When I use the wireless its even more erratic. I listen to music using an airport express that is also connected via ethernet to the Airport extreme but obviously when that keeps cutting in and out.
Was hoping people might have some suggestions here.
Thanks!

Copy down the network address settings when things are ok, then recheck the settings when you have the problem. This will show if your loosing your ip addressing. When you have the problem, try to ping the address of the other computers. If you get a response, this will tell you if the problem is local or connectivity to the internet. (Go to Utilities>Terminal then ping xxx.xxxx.xxxx.xxxx)
