Linksys Wireless Router :: WRT400N Stops Routing Packets Randomly?
Aug 19, 2012
This happens intermittantly. This results in most connections (but not all) being dropped. I will be unable to connect to web servers. My connection to videogame servers will drop. However, AIM will stay connected. These were done simultaneously. The same thing happens with my Cisco AE1200 and a D-Link 802.11g adapter I have. Disconnecting my adapter and reconnecting it solves the problem. I have tried doing a factory reset on the router and installing the latest firmware. It seems to happen more frequently when I am doing a lot of throughput (downloading a game on Steam, for instance) but other times it will happen when all I am doing is playing a game (like Tribes Ascend) which uses very little data. This is extremely frustrating. When I pay more than $150 for a piece of networking equipment, I expect it to last more than 3 years.

Having a problem with port forwarding on their WRT400N? I'm forwarding one service (https) and this stops working if it's not accessed after a 10 days or so. The only way to get it to work again is to reboot the router. I’m running the “latest" firmware, which is an oxymoron considering it's been over 12 MONTHS since Linksys updated the code... Which is appalling considering this appears to be their flagship wireless N router.

The wireless drops specifically from my laptop constantly at random times. When the wireless drops in order for me to be able to reconnect i have to restart the router itself. There are also random times where the Wi-Fi stops broadcasting altogether. I have a computer connected via Ethernet and it does not lose connection during these times. All the computers are running Windows 7 and the Router is up to date on firmware.

I have downloaded netflix on our wii. We have a E1000 Linksys router.
While watching anything on Nextflix, the movie stops every 2 minutes and began loading again.

Router randomly stops working and sometimes reconnects by it self and sometimes I have to manual reset the router. Also I only get 2-3 bars wireless. Is my router not configured properly or damaged?

I just bought a dlink 655 from amazon and for some reason the router stops broadcasting on wifi. I cannot connect to it through my laptop or ps3. The only thing that fixes this is removing the plug from the back of it and putting it back in, once i do this, the SSID shows up once again and all is well until the next day (or 2 days after)

My internet works fine but after a random period of time, usually 20-30 minutes the internet stops responding. I have ran a diagnostics test using the Intel PROset/wireless tools program and it states on the ping test that there is no response from the default gateway and the DHCP server.

We have a situation with 20 4410N's They are connected through a 2960 switch. They runned for about a year with no problems. We use the WiFi system with 10 cisco wireless ip phones, several workstations (5-10) and a few mobile devices.
Three weeks ago we took 10-15 iPads in commission (almost equally divided over the AP's), since then the trouble started. Several accesspoints stop randomly responding a few times a, day. We updated to the latest firmware (2.0.4.2), but that did not solve the problems.
Were using 3 SSID's WPA2 encryption and fixed IP's for the AP's. If we can't get a hold on this we have to replace all the AP's by other ones.

I've been using an 802.11 b/g USB wireless network adapter card with my computer to use in conjunction with an AT&T 2Wire router,which is about 20 or 30 feet away off in another room.After about 10 minutes on average, the adapter will stop transferring data suddenly, and it will stay that way for a while. If I do nothing, then sometimes it will start up again after several more minutes, but instead of waiting, I usually will select "Repair" from the Wireless Network Connection pop-up menu, which also works to get it started again. The problem though, naturally, is that after another little while, like about 10 minutes again, it will short out all over again. Sometimes, very rarely, it will stay working for up to maybe an hour, and sometimes, it can short out yet again within a few seconds.

I am trying to troubleshoot my own router (Linksys) issues with using Lync and accessing some sharepoint sites that are internal to my company's network. I am connecting to the Internet using a Linksys router (WRT400N). When I have my work laptop using RESCUE GFE hardwired directly to the modem - and then connecting to VPN - I can connect to Lync and work normally. However, when I move connection via the router - I can no longer connect to Lync nor access some Sharepoints. I can access VPN fine but with Lync I get an error stating "Your Lync account does not allow access from outside your organization's network. Please connect to your organization's network and try again. However, I am connected via the VPN.this connection worked with a prior laptop using WinXP (I am no on Win7) and the connection thru router and using VPN worked with Communicator.I unfortunately had to reset my router - so I cannot recall if there were port settings established from the last time I had to set up the network. I didn't save the configuration; note to self - save configuration in future.

I just did a reformat on my laptop, therefore I had to reconnect with my router. I put in the correct encryption key.. however as soon as i got connected, it just kept saying *Authenticating* for about 5-10 minutes then it disconnects me.. What i can do to stop this?The router itself was installed on a shared computer (I live with several roomates) and that particular computer got replaced.. does that matter to the router? the new one doesn't have the program installed.

Recently upgraded to WRT400N from older 54G. Opened ports to my Linksys IP Cameras and can access via DynDNS address (using Modem addressort) from inside my network but not remotely. If I disable SPI Firewall it works from outside my network ... am I missing a step ... never had this problem with 54G and although I run software firewall on my computers I like the thought of added security of a firewall on my router.

Been having random connection drops for the past few weeks where I would see the network connections to the router just drop either on a wireless connection or a wired cat 5 connection. As of tonight I cant connect to the router at all. If I disconnect and reconnect the power after 30 seconds it will come up for a short time but then I will lose it again. linksys as my router is out of warrenty. I'v searched around for similiar problems people have been having, but it seems like mostly involve just the internet connection. I still have the same firmware for the routers as the day I purchased it and the router sits on my desk in a ventilated area not overheating. I can do to further diagnose the problem, I have even tried resetting to factory defaults. I try to diagnose the problem or see if my router is just dead.

Check to see if there is a firmware upgrade and there is. Well I updated it with the newest and only one out there. I did the upgrade, said sucessful and now it will just random reboot or something........ every few minutes the power light starts flashing....... then all the light go out, then power flashes again and it comes back up. I have tried many times to reflash it with that new firmware but no avail. I wish I had the old firmware back because it was working fine till I did this upgrade.

I cannot get internet Wake on LAN to work via my wrt400n . (It works fine on my LAN - so I know that the pc is configured properly. Further, I know that port forwarding is set up correctly, as other applications are using forwarded ports and are working correctly). The issue seems to be that the magic packets are being blocked by the router or they are received but the router doesn't know where to route them. I monitor the network and the never see the magic packet on my subnet. how do I set up a static ARP route on the wrt400n? I suspect that I may need to create a static ARP to resolve the issue.

E3200 works great until I enable QoS. The device uses QoS and works find until reboot. If QoS is enabled and the device is rebooted, its stops routing from LAN side to Internet side. Administration-->Diagnostics allow me to ping/trace route to Internet sites and local LAN clients but cannot reach Internet from local LAN.
Windows networking icon indicates "No Internet access". I can ping other devices on local LAN.
Disabling QoS restores routing and you can re-enable QoS after that and all is well. Unfortunately, if there is a power failure when I', not there to disable/re-enable QoS afterward, other household members can't use the Internet till I get home.
Wondering if any other QoS users have observed the same problem.

I would like to configure it as an access point on my LAN, similar to the way my WAP55AG works.My research on the Internet and on these forums indicate that I have to disable DHCP on the router as well as use the LAN ports to connect it to my network.I am able to turn off DHCP, but assigning it a static IP address is challenging.I can set the IP address, but I am unable to set the subnet mask to 255.255.254.0 as I am only getting a set of SM in a drop down list whick are all 255.255.255.x

I have a WRT400N and approximately every 30-45 minutes the router will drop all connections (wired and wireless), all the lights will go out and then power light (far right light) will flash for a minute or so. I have tried connecting directly to my modem and I have no problems at all.

I have been experiencing intermittent issues with download speeds of 1-3 MB and ironically upload speeds of almost 10MB. When everything is working fine I get download speeds of about 35MB and upload speeds of 5MB which is normal. This issue comes and goes. I had Comcast come out several times and we finally pinpointed it back to the WRT400N router. The Comcast modem is a Cisco DPC3008 model. I know there are known issues with the Cisco WRT400N but have had a hard time finding the information. Any known issues for this model and if so what are the fixes. BTW, the firmware is up to date.

Region : Argentina
Model : TL-WR1043ND
Hardware Version : v1
Firmware Version :
ISP :
Region : UnitedStates
Model : TL-WR1043ND
Hardware Version : v1
Firmware Version : 3.13.12 Build 120405 rel 33996n
ISP : Verizon Fios
(My router says Version 1.9).Had this router about a month. It works fine. Using it in Wireless mode wpa2 security. Get excellent speeds. HOWEVER> It freqently drops connectivity and fails to allow wireless clients to connect at all. (You can see the SSID via wireless clients, but not connect to it). To restore it, I have to disconnect from Power, wait a moment, then reconnect to power. It recycles and connections are working again with no problems (UNTIL NEXT TIME). Seems to happen every few days.
I checked the web site and I appear to have the most current firmware.I have a Trendnet router on different channels in another part of the house which has never had this problem. I disconnected it to test if it was somehow involved, but the TP-Link router had same symptoms when it (trendnet) was not connected. Our Actiontec Router (VERIZON provides this as base connectin to them serving the Cable TV DVRs also) ) has its wireless disabled and is the DHCP server provider to the home network. DHCP is disabled on the TP Link.

I'm having a little trouble connecting a new computer to my wireless network. I have a WRT400N router and I'm connecting an older computer to it. The computer runs off Windows XP and the router itself is a WUS854G. We can get the adapter to say that it is connected to the network, but the router will not assign it a new IP address or even acknowledge that it is connected on the MAC client list. We manually forced a new IP, which allowed the computer to connect (though, again, the router did not show that it had been connected to.) but despite the connection being "Excellent" we could not access the internet. Furthermore when we tried to refresh the connection the IP address reverted to the original setting.

Just bought a WRT400N and set it up using 5ghz and 2.4ghz bands, and using WPA TKIP for both. Problem is that both my laptop and my iphone occassionally lose connectivity and my iPhone says that my WPA key isn't valid.

I have the WRT400N router with the latest firmware. Recently I have noticed a device in my DHCP that I do not recognize. It is not device I own (believe me, I have racked my brain and confirmed) as it shows as an Acer pc. I cannot ping the IP address however. I have rebooted my router several times thinking maybe it's a former connected device but saved in memory but it keeps coming back. I am thinking possibly it is someone hi-jacking my Internet, but not sure. I am using WEP security but it shows a LAN connection which is strange for a wireless device. The only hard wired pc is my HP.

I've had been successfully using a WRT400N to extend my wireless network as follows:
The WRT400N connected to my network via an Ethernet port in my kitchen. The cable ran down to a corner of my basement connecting to Verizon router that brings in our Internet, TV etc.
The Verizon router's poor location was a problem, and placing the WRT400N in the kitchen worked perfectly, providing excellent network access and Internet to wireless devices throughout my home. It worked fine for over a year.
Recently, we had a power outage which reset the WRT400N to factory settings. and I am having trouble getting it to work again. I set it up in the first place, but am now having difficulties. Clearly, I am no guru!
I tried to get it going again by: 1) plugging the WRT400N into a PC and giving it a new IP address that would not conflict with the Verizon router (both default to 192.168.1.1) 2) turning off DHCP, 3) renaming the router, 4) changing the router password, 5) setting up a WPA2 security key.
I then plugged the WRT400N back into the kitchen Ethernet port, but something is wrong. Wireless devices cannot find the WRT400N.
The good news is that I can "see" the WRT400N through any PC on the network via a browser and access setup, but the bad news is that devices cannot see or connect to the wireless signal.
When I go to "Status" it shows the IP address, subnet address and default gateway all at 0.0.0.0. On the SETUP page, it has the correct router address (192.168.1.9), and a subnet mask of 255.255.255.0. Not sure if it is supposed to be this way...

I've had the WRT400N for about a year and a half now and just last night it stopped sending out data when connected to my cable modem. I've tried connecting the modem directly to my Mac and it works just fine (that's how I'm sending this message now). But when the modem is connected to the router, I get no data. It connects to both the 5 Ghz and 2.4 Ghz networks, but it refuses to send data through the pipe. I've tried power cycling both the modem and the router to no avail.

I am trying to set up an access policy on my WRT400N. Whenever an access policy is enabled, all internet acess is completely blocked. This occurs irregardless of what the access policy is supposed to block. Even a blank access policy that allows access to everything and doesn't have any computers registered still blocks everything. How do I get it to stop completely blocking internet access?

We had a power outage the other day, and now the wireless router cannot connect to the internet. Network Magic shows there is no connection from the device to the internet. I tried repairing it through Network Magic but it wasn't able to fix it.
My PC is directly connected to the wireless device by LAN cable. If I connect the PC directly to my DSL router I can connect to the internet, but not if I connect to the wireless router and from there to my DSL router. I tried resetting the wireless router to factory defaults and then going to [URL] and resetting up the router security settings. But Network Magic still shows the bad internet connection.
I then tried resetting the router to factory defaults again and installing it from scratch using the setup CD but that failed as well. I'm not at home right now so can't remember exactly at which point it was but I think it was either when the setup wizard tried to detect the device or install the device.This is the second time I've had to reset up my router due to power outage. Last time I was able to get it working by doing the first steps above.

My WRT400n has started dropping the wireless signal 4 to 5 times a day. Somet times it fixes itself but most of the time I have to re-boot the router to connect a wireless signal.I looked for a firmware upgrade but there hasn't been one since 2009.
