a couple days ago my BEFSR41 started making trouble, and so far I have not been able to get it working properly again. When I hook up my laptop directly to the cable modem everything works fine, and I get an IP address via DHCP. When I connect through the router, though, the router status shows 0.0.0.0 for all DNS, gateway, etc. addresses, and even pressing DHCP Release/Renew doesn't change that.Also, in the log I see these messages:
2012-08-08 20:30:41 warning DHCP RENEW WARNING - Field invalid in response
2012-08-08 08:30:52 notice TLV-11 - unrecognized OID
Since I can connect to the cable modem directly, it seems the cable modem is not at fault.My overall setup is:
- BEFCMU10 cable modem
- BEFSR41 (not sure which version, but I believe it's a 4.x)
- WAP54G
Could it be that my provider (Cox Communications) has changed some configuration in their DHCP server, and my laptop (MacBook Pro) can handle it, but the router cannot?
On the BEFSR41 v1 series and WRT54G series, what is the maximum value for the DHCP "Client Lease Time (in minutes)?" It seems that 2^16 -1 (65535) minutes is the max. This is about 45 days. has the max value changed with newer versions of these devices?
Most devices pass a client name to DHCP when requesting an IP, but some like my smartphone, do not. When a device does not pass a client name garbage is entered as the name of the client name.The first is that when you use the Web Admin pages, and select Status/Local Network/DHCP Clients, the table will not display any clients because there is an error on the page. If you right click and View Source from the browser, you will see all the client entries are there and one of them will have garbage (unprintable characters) for the client name.The second and more serious issue is that the internal DHCP table once corrupt is unstable. I've had my BEFSR41 reboot because of the corruption and then I get IP conflicts on my LAN because the DHCP starts handing out in-use IPs.I'm on hardware version 4.3 and the latest firmware Ver.2.00.4 Build 8 (which is very difficult to install without bricking the router). BTW, when I use a WRT54GL router with the smartphone, it is properly handled by the DHCP and shows a blank client name, not garbage.
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.

I just bought an e4200. I was using a LinkSys WRT54GS running DD-WRT alternative firmware.
One feature that I really liked in DD-WRT was the ability to assign static IP leases from the DHCP server. I liked having all of my devices running with a predictable, known IP address on my network. I have a Home Theater PC, and various controller applications that run on iPhones, etc. - some pretty homebrewed. Configuring the firewalls, etc. was much easier with IP address based controls.
Is there a way to achieve the same within the e4200's stock firmware?
we finally got my Cisco refurbished E2500 configured and working downstream from a UVerse 3801HGV box. We had to change the default IP address of the 3801 because it conflicted with the E2500's default. The E2500 is set up to get its Internet IP address using DHCP from the 3801. This is working fine for normal web browsing, etc. However, anything that requires extended connections (downloads, streaming, etc) freezes after a couple of minutes, forcing me to refresh the action to get it started again. Extremely annoying to say the least.
I'm pretty sure that I've tracked it down to the E2500's configuration of the 3801's DHCP allocation. For some reason, the E2500 wants to set the DHCP Lease Time for the 3801's assigned IP address to 10 minutes regardless of the upstream settings from the 3801. The 3801's default is 24 Hours which I've changed to 168Hours (7 days), but the E2500 stays stuck at 10 Minutes. Specifically, I'm referring to the setting displayed on the E2500 under Status>Router>Internet Connection IPV4>DHCP Lease Time.
I have a Linksys WRT310N v1 with firmware v1.0.10 build 002Jul 19, 2010 My router fails to renew it's DHCP lease from my cable provider, causing internet access to drop. I can still access my cable modem at 192.168.100.1, but I must do a "IP Address Release" then "IP Address Renew" to get back internet access. The router works fine otherwise.
I'm trying to change the DHCP Client Lease Time from 1440 minutes to 480 minutes. When I try to apply the new settings, I'm getting a message that says "Invalid Characters" and it won't stick. I've tried this in three different up-to-date browsers (ie10, Chrome and Firefox). Also, I'm connecting locally through LAN and I have the latest EA6500 Firmware: 2.1.39.145204
I have the setup disk and want to set up a password for the router. Don't want to mess things up since the system was installed by a pro. How do I simply enter a password to be used to connect?
I have an AT&T Univese which is class G. I want to run it in class N.Do you think plugging my Linksys router into the AT&T will give it to me(class n)?If so, how do I get the linksys parameters set up? It giving wrong readings at its not connecting to the internet.
My internet supplier is Comcast. I have a problem with a URL that will not load or I could not connect to that site. Comcast said it was my router that was probably the reason. I have not had any problem in the span of using this model and version before. Should I be looking for firmware upgrade or a new router? Operating system is MAC OSX 10.5. Using router to network 2 MACs.
I have a BEFSR41 that often goes brain-dead and the DHCP stops working. I've tried three times to download and install new firmware but it always fails with a "pattern mismatch". My current firmware version is 2.00.02 and the file I am downloading is 2.00.04 build 8. Yes, I have verified that my hardware version is 4.3.The download file from this website is corrupted.
I have a Century Link DSL connection in my house and its working fine. I just got a new Linksys BEFSR41 v.3. I am trying to set it up for my PC, Xbox360 and BD player. Everything works fine when I plug them in to the DSL modem 1 by 1 but when I try to put the Linksys "in the middle"... nothing... So I'm pretty sure its not my DSL modem or connection.All the lights come up on the Linksys as they should (power, internet and the Ethernet) but for some reason it seems the internet not getting trought the router. When its connected and I pull up my internet browser I type 192.168.1.1 and it takes me to the linksys config site. Without the router in the same address go to the Westell site as thats my DSL modem. Everything looks fine on the config site. All the correct IP, MAC, DNS address are there and still no internet access on any of my device.
I have problem with Linksys BEFSR41 ver.4.2 (Firmware Version: 2.00.4 )When i plug the cable on internet port , router crash , can't see web configuration if get ip or to make some ather configure, only if unplag internet cable and restart the router i can see the web configuration .(i try to ping in local ip when crash 192.168.1.1 but not responding )in my computer i have static ip (192.168.1.5) and is direct connect with Linksys.i try it and with DHCP and plugent over LevelOne switch and over Cisco switch .[code]
in previous firmware they don't have in menu the server ip in wan pptp web configuration connection I have test with more than one Linksys BEFSR41 ver.4.2 and all router have the same problemWith ather router e.x. Cisco RVS4000 configured and working perfect in same network .
Comcast upgraded me to a 30 Mbps speed, and my trusty old BEFSR41 v2 doesn't cut it. Cisco promotes wireless routers with a 1 Gbps ethernet, I would rather have a wired router, and use a WAP that I can unplug when I am not using it, since, for now, I only connect my work notebook wirelessly. Most wireless routers also generate a lot more heat than a wired one does, and I don't need any more heat in my Houston home.A new BEFSR41 v4.3 is only 10/100 Mbps. There doesn't seem to be any 1 Gbps wired routers for home use. Will a new BEFSR41 give me 100% of the cable Dociss 3.0 speed, or would I need to get a 1 Gbps router to get the fastest throughput? Or do I only need to upgrade when the cable speed increases closer to 100 Gbps?If a 1 Gbps router is better, are there any simple business wired routers you could recommend?
I have recently been having difficulty with my router. We have 2 computers and our xbox hooked up to the router and for the last few days whenever both of the computers are in use we experience frequent disconnects. It does not happen when it is just one computer and the xbox running, but as soon as both computers are in use it happens. The disconnects are very brief but extremely frustrating when I'm trying to play a game. I have the most up to date firmware according to the linksys site
I am using a Windows 7 machine and I'm pretty sure the ethernet cable that I'm using is functional, considering that I'm using it to connect to the Internet right now.I've been trying to get my router going for a while now and I'm pretty sure I've tried everything that the internet has advised. I've screwed around with the card speed, 10 mbps Half Duplex didn't work or anything. I've manually set the IP and related stuff to 192.168.1.x and the works. I've tried to manually run the setup, although that definitely didn't work considering that my computer can't even detect the dang router. I've screwed around with the wiring and restarted my router and modem constantly.
i tried to upgrade my BEFSR41 model 4.2 to a newer firmware (FW_BEFSR41v4.3_2.00.4.5_20080603_code.bin) and got a blinking power led. I've tried to power cycle (several times), reset (several times, 30/60 secs), unbrick (several times) and still have flashing power led. My connection to the router looks like:
Request timed out.Request timed out.Request timed out.Reply from 192.168.1.1: bytes=32 time<1ms TTL=64Reply from 192.168.1.1: bytes=32 time<1ms TTL=64Reply from 192.168.1.1: bytes=32 time<1ms TTL=64Reply from 192.168.1.1: bytes=32 time<1ms TTL=64Reply from 192.168.1.1: bytes=32 time<1ms TTL=64Reply from 192.168.1.1: bytes=32 time<1ms TTL=64Reply from 192.168.1.1: bytes=32 time<1ms TTL=64Reply from 192.168.1.1: bytes=32 time<1ms TTL=64Request timed out.Request timed out.Request timed out.Request timed out.Request timed out.Request timed out.Request timed out.Request timed out.Reply from 192.168.1.2: Destination host unreachable.Request timed out.(and offline until the next reset)
I have just received this device from my deceased son-in-law and I need to know how to change the password. I do not know his and have no way of getting it.
I just have a quick question about the TFTP utilities that Linksys has. I tried to upgrade the firmware of my BEFSR41 v1 router using the TFTP utility for a BEFSX41 and it didn't work(I just hope I did it correctly).
So, the question is, are these utilities router-specific or they should work with other routers as well?
My cable modem works fine when not running through the router. However, when running through the router, the internet won't work.I tried unplugging the power and plugging it back in, as well as holding down the reset button for 30 seconds, but nothing worked.
I went a bought a brand new model V4.3. I had trouble installing it right from the word GO, but I did successfully get that acomplished, how ever one of the important features "logging of incoming and out going ip" won't work at all. I tried deleting the old logview.exe and rebooting everything, then installed the "new" logviewer.exe. Well absolutely nothing happens. I have double and triple checked the setting in the router...logging is turned on, the computer which has the logviewer.exe installed is the confirmed network ip i.e. 192.168.1.101 and I can and do access the internet and all other computers on the network from that computer.
how to use a packet sniffer for a night school class, but lack a hub at home. I only have a BEFSR41 Cable/DSL Router with 4-port switch.Is there any safe way to use active sniffing methods? Would the "Mac Flooding" I've heard about work, or do I need to find some kind of ARP poisoning method?Unfortunately while I do recall using Etherpeek around 10 years ago, it was at a very basic level and I'm out of practice.Is there a way to make the switch act like a hub?
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 have 2 PCs and am using a Linksys befsr41 router.The first PC connects fine. The 2nd PC does not find a connection. BTW, when I connect my laptop to the 2nd port, it sees the connection immediately - the lights flash on the ethernet connection. No lights on the 2nd desktop PC.
i have a BEFSR41 v3 firmware v 1.05.00 - i have been usuing 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 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.Then one day i started getting this weird 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.
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 the limited or no connectivity reappeared and the previous solutions did not work to fix it - after searching for a fix i discovered that i could simply unplug the router and the plug it back in and this would solve the problem. This solution worked many 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 reported The IP address lease 192.168.1.100 for the Network Card with network address0xxxxxxxxx has been denied by the DHCP server 192.168.1.1. {The DHCP Serversent a DHCPNACK message}.Now the even viewer just tells me it is using ip address 169.254.xxxxxx - (not the exact message but i didn't wanna go back and look)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.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 even tried different cables and switching ports on the router.
I am using a BEFSR41 for my network. My internal netmask is 255.255.0.0. The only options permitted in the dropdown list on the BEFSR41 is 255.255.255.0. How to change the netmask?
