one day about 2 weeks ago, my net stopped working just randomly. I get the error 'Local Area Connection doesn't have a valid IP' when i try to use the router, and some 'unidentified network' shows up, i cannot connect to it.
I reset everything and unplugged everything but couldnt get it to work until i unplugged from the router and plugged my computer directly to the modem. A good fix to get the net going in a pinch but it has become a real problem with me, my husband and my kids all using one computer when we're used to having our own. You cant even imagine the drama.
I've tried everything i can to fix it, usually google gets me through anything i cant fix on my own and i did come across a few other people having my problem, they all seemed to fix it by disable a bonjour process. I had the same service running but their trick to disable it didnt fix my problem, it is still exactly the same.
Another suggestion was to get rid of windows 7 driver
for the network card and use the vendors own driver, tried that, made no diff either. also tried rolling back to several different times but for some reason the process failed.
i dont know what caused it, i cant remember if anything new was updated that day.. i dont think so, but im not certain, i have even gotten rid of all internet security and tried disabling windows firewall too.
I dont know what else to do but we cant go on with one working computer for much longer!!
