Odd problem: 8-port Switch needed to be reset?
Posted by MAG on July 10th, 2004


Hi folks-

I just recovered from the darndest thing and am hoping someone can
explain it to me.

In summary, a Linksys 8-port switch needed to be power-cycled. That
fixed the problem. My curiosity comes from me not knowing that there
was anything in the switch prone to going into limbo and needing a reset
cycle. Any comments?

My network consists of the cable modem (RCA DCM235) which was giving me
normal blinks during my "service interruption" problem, so I was not
surprised when I plugged my laptop into it directly and got a good
connection.

After returning the cable modem output connection to its usual position
on the router WAN port, I then power cycled the router and wireless
access point (in my office I use a hardwired cable connection, when
roaming around the house I use the wireless card, and for reasons not
worth going into here I have a separate Linksys router and Belkin
W.A.P.). Still no connection to my computer through my office wire
connection or via wireless.

Then I noticed that the 8-port switch that plugs into the router and
happens to provide the feed to the access point as well as my office
ethernet cable didn't power cycle (since it's not plugged into the UPS,
and I used the UPS switch to cycle the other components).

I unplugged/replugged the switch and all returned to normal.

So, what's in a switch that would fail like this? It was working fine
last night.
