Inspiron 5100 - Broadcom built-in network adapter problem
Hi!
I have a problem with my Inspiron 5100's built-in network adapter :
When I plug in a network cable (I tried several cables...), the PC seem to detect the connection but it drops it after one second, detects it again after one second, drops it, and on and on... the orange and yellow leds over the ethernet plug go up and down each second...
The adapter is installed correctly in WinXP...
I cleaned the ethernet port's pins with contact cleaner... always the same problem ;-(
Sounds like a link speed negotiation problem. If possible, set the speed and duplex the same on both ends of the Ethernet connection, and see if that stabilizes things.
Mmm... the problem arises on all kinds of connexion types : connected directly to a Linksys router (100Mbps), connected directly to a cable modem (10Mbps), connected to another computer using a cross cable...
Do the I5100 diagnostics include a test of the Broadcom adapter? If so, take a look with them.
Have you ruled out the possibility of link speed negotiation being the source of the problem by locking the speed on the 5100? I admit, with that many different failures, it's unlikely that speed negotiation's the source of the problem.
Called service by phone and tolled them what the problem was... but as soon as I started doing the tests they asked me to do, everything worked... before I even touched a thing!
