As I mentioned, I'm not sure it's my router (BEFSR41), but things are
behaving strangely.... which is not uncommon in the computer world. I've
heard only a few negative comments about Linksys so it's probably something
else judging by the responses. Something is unstable and I guess I'll just
have to track it down. I was hoping is was something obvious. What's odd
is that it shows a connection, but can't log on to the internet or get email
as well as it can't "see" my other computers. If I plug in my DSL modem
directly to this computer, it automatically reconfigures it and when I
reconnect (through the router) as it was before, all goes back to normal.
I have a number of BEFSR41's in different locations -- all have been running
fine, some for almost 4 years now. Yet some people have had legitimate
problems, so it wouldn't be unheard of for yours to go bad. You need to do
more troubleshooting, though.
Bear in mind that when you talk about "seeing" other computers on the LAN,
you're usually referring to the browsemaster, a feature of Windows, not of
the router or hub. The Linksys can be working fine, but if Windows has a
browsemaster problem, computers may not show up in "Network Neighborhood".
To troubleshoot this, use winipcfg or ipconfig (depending on Win version) to
see if each machine is getting a proper IP address, not something in the
169.xxx.xxx.xxx range. If you're using the Linksys as a DHCP server, make
sure there's not another DHCP server somewhere. If you're getting a valid
IP address, check whether you can ping each machine from the others using
the IP address. If you can, then see if you can map a network drive from a
command prompt (e.g., "net use N: \\othermachine\sharename"). If you can,
then your network is working and it sounds like a Windows browsemaster
problem. Beware any firewalls running on various machines while you're
doing these tests.
The internet problem may be trouble finding the gateway IP or DNS servers.
Again with winipcfg or ipconfig, see if each machine is picking up valid
gateway (probably 192.168.1.1) and DNS IP addresses. You mention DSL, so
don't forget to also check for PPPoE login problems.
These are just a few suggestions. For more focused advice, you may want to
