I use Windows Vista Home Basic, and get my internet connection via a LAN to my son's Linksys BEFSR41 downstairs. I occasionally need to shut my computer down for a few hours, and I restart it I find my internet connection is lost. The dianostic error message reads "Connection unplugged". I would appreciate help with this annoying problem!
Ok, the router hangs. Is your BEFW11S4 a version 4 model? Look on the serial number tag.
If so, here is some beta firmware that *MIGHT* solve the hangs. No warranty expressed or implied. Make sure it's a v4 mutation, not one of the others:
Should this convert your BEFW11S4 v4 into a doorstop or smoking ruin, I'll pretend I never even mentioned it and deny all knowledge. On the other hand, if it works, I certainly would be interested as I've been too lazy|busy to try it.
Oops(tm). Sorry, I wasn't paying attention. Since this is a
*WIRELESS* usenet group, I assumed you were using a wireless router.
I agree with Mr. RBM. You may have a loose connector or intermittent CAT5 cable connection. Look for chewed (mice, cats, puppy, kids, furniture) cable. Inspect the RJ45 connectors at both ends. The usual is a bad crimp job on the RJ45 plug. You can check for continuity by observing the lights on the RJ45 connector at both ends.
It's also possible to create *internet* connection problems with an MTU mismatch. See article at:
It's unlikely that this is the cause of a "connection lost" message, but might some creative way for Vista to announce that it has lost internet connectivity. It's worth checking. If you're using DSL, the correct MTU is probably 1492 instead of 1500. I would need to know what program is generating the "connection lost" error message to determine if it's referring to the internet connection, or the local wired CAT5 LAN connection.
If that's not the case, there's a few DHCP oddities in Vista. Failure to renew the DHCP lease will cause a similar error after about a day of continuous connection (depends on the DHCP lease time). See:
for a short (but growing) list of Vista DHCP related issues (bugs).
I would also verify that you have the latest firmware in your BEFSR41 v2.1. This might be awkward as the Linksys web pile lists version
2.0, but not 2.1 for the BEFSR4.1. However, the version history shows
2.x, so using the firmware for 2.0 will probably work.
On my BEFW11S4 v4 I backed off from a later firmware version (don't remember which) to version 1.50.10 and it seemed to solve the streaming problems and continual need to reset. Currently it is a wireless accesspoint only and seems rock solid for that use. [BEFW11S4 v4 accesspoint only] to [Linksys switch] to [Netopia 2241N DSL modem/router].
At one point, I went back to 1.50.14, which did NOT solve the hang and reconnection failure problem. However, I didn't try 1.5.10. I'll give it a try. At this point, I have 3 of them, and all are next to useless. However, as I previously mumbled, it't not the wireless section that hangs. It's the router section.
