Linksys Wired Router :: BEFSR41 V4.3 Latest Firmware - Frequent Internet Drops?
Jan 14, 2011
2 brand new routers (BEFSR41 v4.3) Firmware - 2.00.4 Build 8, 10-19-2010 - both same problems:Frequent Internet drops, daily resets required.I'm 99.9% sure there's either a defect in this model, or a serious screwup in this firmware.My router uses an IP address, with DHCP off. Also, we have cable modem. Plugging in directly to cable modem works fine.I am an experienced network admin, so refrain from the usual reset / try again response. Have there been many issues with this model and / or firmware? Have there been many returns?

I have a BEFSR41 that has been flawless to date but it is version 1 (I think). I have gigabit nics on all PCs but I am wondering if the old version 1 is only capable of 10mbps throughput. If that is the case then it may explain why I can get up to 20mbps download speeds off the modem and under 10mbps off the router. The router has the latest firmware and otherwise no problems.

I have a linksys router(befsr41 v3) with the latest firmware(1.05.00) - i have been using it for at least 7 or 8 years now - at one time i had 3 computers hooked up and they all three worked fine. Now i have 2 plugged into the router - both are xppro machines - the one i am on now works with no problems. The other computer however has the limited or no connectivity problem.I used this router for years without any problems then one day this ip conflict message started to appear.
I started getting this ip conflict message on both computers but only occasionaly - it never caused any problems - if you ignored it - it would simply go away.Then one day computer #2 got the limited or no connectivity message - i simple reboot fixed it. This solution worked several times. Computer #1 has never had any problems with the internet connection.Sometime later the limited or no connectivity problem reappeared and this time a reboot did not work - i searched for a fix and decided to try changing the link speed from auto sense to 10mb half duplex - this solved the problem. This solution worked several times.
Sometime after that the limited or no connectivity reappeared and after some searching i upgraded the routers firmware - this solved the problem.Sometime later the limited or no connectivity reappeared and this time i had to actually uninstall the NIC, reboot and then let it redetect the NIC and then the problem was fixed. This solution worked several times.Sometime later (wich brings us to 3 or 4 months ago) the limited or no connectivity reappeared and this time after searching for a fix i was able to fix it by updating the NIC drivers. Problem solved.
This brings us to now - the limited or no connectivity has reappeared and none of the previous fixes correct the problem.When i originally set everything up it worked immediately out of the box.DHCP is enabled - everything is set to obtain an ip address automatically.At first the event viewer on computer #2 reported The IP address lease 192.168.1.100 for the Network Card with network address 0xxxxxxxxx has been denied by the DHCP server 192.168.1.1. {The DHCP Server sent a DHCPNACK message}.
Now the even viewer just tells me it is using ip address 169.254.xxxxxx
I have tried all of the previous fixes to no avail. I've tried shutting everything off and turning everything back on - i've tried resetting both the modem and the router - i've tried upgrading the firmware again. I even downloaded LELA and installed it on both computers thinking maybe it would detect and fix the problem buy no such luck. LELA simply tells me that computer #1 is working normally. On computer #2 when i installed LELA the first thing it did was try to find the router and it tells me it cannot find it.
I tried uninstalling the NIC and removing the drivers, rebooting and then reinstalling them. No luck.
I tried setting a static ip on computer #2 with no luck. When i did these two error messages appeared in the event viewer of computer #1---
The master browser has received a server announcement from the computer (computer #2) that believes that it is the master browser for the domain on transport NetBT_Tcpip_{0876E9A8-C6E. The master browser is stopping or an election is being forced.
The name "MSHOME:1d" could not be registered on the Interface with IP address 192.168.1.100. The machine with the IP address 192.168.1.20 did not allow the name to be claimed by this machine.
If I ping the router from computer #2 it comes back 100% loss.
If I ping the NIC it comes back 0% loss.
I might also add that I can see both computer #1 and #2 in my home network workgroup on both computers. I've tried ipconfig /release and ipconfig /renew - I've tried it one after the other and also a reboot in between. I've tried clicking on repair in the LAN status - I've tried resetting the ip stack with the netsh command - I've even tried different cables and switching ports on the router.

I have what I believe is an original (V1) version of the BEFSR41 gateway/router. The label underneath the device only shows the model number with no version information. Current firmware version on the device is 1.46.02, dated Aug 03 2004.
Can I confirm (1) that I indeed this router is at hardware version 1? If that is the case it appears from your web site that version 1.46.02 is in fact the current and only firmware version for the device and that there are no firmware version upgrades available.
The DHCP software current does not have IP address reservation, which I am interested in adding if possible via firmware upgrade. If not then I have to consider whether I want this feature bad enough to replace the router.

I own a Linksys BEFSR41 v 3.1. I've been attempting to set up a home network with three computers; my main desktop running Windows 7 Pro x64, a netbook running the same OS and a box running Windows Home Server 2011 x64. The firmware listed for my router was initially 1.05.03.
My router has the issue with resetting its administrative password to the factory default and I've been unable to set up remote access to my LAN and home server. I decided to try updating the router's firmware, but none of the versions listed fit the one I have. The label on my router says v 3.1, but Cisco's site only has a 1.0, 2.0, 3.0, then skips to 4.1, 4.2, etc. The instructions on the site warn not to use a version for a different model, but are vague as to exactly what that refers to, as the model # and the version # aren't clearly delineated.
Anyway, I tried using the latest firmware and received the, "File Pattern," error. Although it didn't seem like anything had changed, I reset the router just to be safe, then tried the v 3.0 firmware update, thinking that the software was intended for all revisions of v3.0. This time it reported updating without a problem, so I reset the router again and went back to the admin page in my browser to check the firmware version listed. To my annoyance, the firmware is now listed as 1.05.00 - i.e. an earlier version than what was shipped on the router.
This means that not only is the issue of the password resetting not fixed, but any other fixes included in the original firmware are now wiped out as well and, needless to say, I still can't set up remote access properly.
How do I restore the firmware version? Neither a reset nor a, "Restore to Factory Defaults," does this. How do I find an actual update for the router? I can't find any mention of a v 3.1 on Cisco's site, let alone support information specific to this model and version.

My BEFSR41 Ver4.2 cannot startup after upgrade firmware to Ver.2.00.4 Build 5. I am sure the upgrade is completed, but the Power light keep blinking after restart. All devices cannot get IP address. The manage page (192.168.1.1) cannot be access even I input a IP address of my NIC manually.

I have upgraded the firmware on my Linksys BEFSR41 V4.3 router. On this router i used Statis IP (so DHCP enabled). This worked fine on my network, until this upgrade. Now when i try to ad another static IP , or when i want to change something in the Routing-tab, i get this message ' Wrong Gateway Input! It should be the same subnet with WAN IP'. Strange because i haven't changed anything in the settings.I already did a complete reset on the router, still the same problem.

I have a BEFSR41 V2 router connected to a westell c90 modem and my provider is Bellsouth.net (AT&T). I have the modem set to PPPoE and DHCP enabled. I am using the router as a gateway. The router's status page indicates that is communicating with the modem. Release and renew works and I can detect the addresses of the modem. I just can't pull up websites. I am wondering if this router (12 years old) is not compatable with the service.

I upgraded the firmware on my BEFS41 v4.3 to the Ver.2.00.4 Build 8, off the cisco website. After I received the successfully upgraded message, I could no longer connect to the internet, nor could I connect to the router's configuration page. I tried to do a few hard resets and connecting it to other computers to see any other computers could connect to it, no luck. I tried connecting one computer just to the router, without the internet plugged in, and tried to ping 192.168.1.1 but I received a "transmit failed, error code 1231." Is there anyway I can access this and change the firmware, or am I screwed?

I have a Linksys router (model BEFSR41) and I all the outputs going to two computers and two gaming systems (X360 and PS3). I have had the router for over a year and it works fine, but I recently decided to attempt to have my 360 access the media on my computer by linking the two together through the Media Center. To do this, I needed to enable my router to allow UPnP (according to Microsoft help). When I did enable this, the router would disconnect me every 2-5 seconds from the internet, then would reconnect me right away.I have no clue why it was doing this (it occured across all of my devices) so I just disabled UPnP and things went back to normal. How to fix this so that I can have a consistent and stable connection when I have UPnP enabled?

I have a home network with a wired BEFSR41 that, for a variety of reasons, MUST be manually IP configured (DHCP off). All computers and other devices connected to it are manually IP configured. I desire to add a device that cannot be manually configured, and needs DHCP. I therefore need to daisy-chain two routers with the second one DHCP on (and manual IP connection to the main network). The new device needs two-way internet access, but doesn't care if it sees any other current network devices. I've tried several configurations, none seem to work.

what is latest firmware version is for router WRT 160n (v1). The Linksys site currently states that it is Ver.1.02.11 (11/08/10). However, on the admin page for my actual router it states v1.52.0 Nov 16, 2007. These versions #s and dates don't jive. How could I have a supposedly newer version that is older than the most recent one posted?
