I just found these forums and it seems like you guys know your stuff.
I work in a small office, and several of our computers have recently updated to Windows 7 Home Premium (formerly Windows Vista -- not sure exactly which version).
Ever since the upgrade, network connection has been flakey after boot up. Sometimes it will say I'm not connected to any network.
The weird part is, it only happens sometimes. Other times after boot up it works just fine.
Another interesting quirk is that physically disconnecting the ethernet cable from the box, waiting a few seconds, then reconnecting it will instantly fix the problem -- but again only sometimes. This morning I had to disconnect and reconnect it 3 times before it found the network.
Once it finds the network, there's no problem. Everything works perfectly until the next shutdown.
My first thought was that there was something wrong with the physical cable, but since this symptom has appeared on multiple machines in our office (at least 2), and so soon after an OS upgrade, I just have to believe they're connected somehow.
What should I check first? Could this be a problem with the drivers or network settings?
I don't know much about my computer's specs, as Win7 is pretty new to me and I'm not entirely sure where I can go to look up hardware details, but system properties give me the below info:
Windows 7 Home Premium 32-bit Intel Core2 Duo E4500 @ 2.20GHz 4.00 GB RAM (I don't see any info regarding my ethernet device)
The router I'm connecting to (on the other end of the ethernet cable) is a Qwest / Motorola 3347.
Any help would be greatly appreciated. I'm happy to provide more info if needed.
