Two days ago my WRT54G V6 started cutting out the internet connection
for no reason.
I updated the firmware and that didn't help. Per Google I changed the
MTU from auto to 1492, I thought that worked until just now it cut out
on me.
The cable modem is a Linksys BEFCMU10 version 4.
When I go to its diagnostic page http://192.168.100.1/ this is what I get:

Maybe your router is getting hot or going bad? I have Comcast and the
same router and it works just fine. Have you tried an alternative
software for the router?

Its not getting hot, it has been sitting in the same place for the last
year without a problem. There's no dust.


I heard about alternative firmwares for the Linksys...
Which one should I try?
