Inspiron 5150 Network Cable Unplugged

I have a Inspiron 5150 for about 9 months (broadcom 440x 10/100 internal) XP Home SP2
It has worked flawless for the last 8 1/2 months. Until two weeks ago when it started the
"Network Cable Unplugged" balloon pop-ups.
 
I have changed four patch cables, switched machines with a desktop that behaves, updated the broadcom drivers, updated and ran virus check/ adware check/ spyware check, changed from Auto to 100 Full/ 100 Half/ 10 Full/ 10 Half, Blew out the ethernet port with can air, but it still does the "Network Cable Unplugged".
 
I did notice that it starts about an hour after the machine is running which indicates a heat problem. I even placed a small fan behind the unit to make sure cool air is surrounding the unit. If it wiggle the cable it seems to make a connection for a a few seconds to a few minutes and does the same thing. It can not be the cable since I have swapped 4 plus moved it to a machine that behaves.
 
Is there some place on the motherboard that I should blow off with can air where the broadcom ethernet chip resides?
 
I am out of ideas

I am having a similar problem I keep getting the same message and I have tried several different cables and replaced the hub. Still no difference I have also reloaded new drivers from both the dell site and broadcom. nothing still get the same problem.

Any Ideas hate to replace a motherboard plus unit is out of warranty..

My solution was to say the heck with it I disabled the internal network card anad just bought a pcmcia network card and was on my merry way. From all that I could find is to replace the motherboard.. but to costly for me so a 20 pcmcia card works just fine.

Hi,

My problems are exactly the same with an Inspiron 5150. Did you find any solution yet ?

Hi, I've been having the same problem for a while. The ethernet port will frequently stay disconnected until I wiggle it for a bit, then it only stays connected for a short while.

I'm thinking that it requires a service request to Dell Support, which could get expensive. It's quite sad to think that the ethernet port dies in about a year (I've only had it slightly over a year).

You've got a good cheap solution though; I guess it's time for me to buy a decent, cheap PCMCIA ethernet card.

I also found another solution is to buy the extended warranty on my unit it cost 227 for 2 years which is far cheaper then the cost of the motherboard and when the hard drive crashes in about whenever which they always do on laptops then they it will be covered also.. try this
