LAN Unidentified Network Problem Resurrected
Hi, I've been struggling with my 1 year old Samsung laptop for the last week or so. I have a modicum of tech savvy but please forgive me if I don't always use the right terms. I've been using my laptop steadily with pretty great connection speed for the last 6 month plugged directly into my Time Warner Cable provided modem. A week ago, my internet access suddenly disappeared and left me with the apparently pretty common "Unidentified Network" message.
I could not release nor renew my ip address, which was stuck at a 169.x.x.x style address.
I ran all of the commonly suggested command line actions (TCP/IP, winsock, etc.) which told me that my computer could not connect to the DHCP server.
I disabled, enabled, uninstalled, reinstalled, and updated everything that could be.
I got a new modem. I double checked the cords. (my desktop computer does work when plugged in)
I disabled the Windows firewall.
I disabled the wireless card to make sure it wasn't interfering.
I double checked that I had uninstalled the preinstalled Norton and McAfee programs.
I reformatted my computer (auuuugghhh)
And then I did all of that again.
All of which was utterly to no avail.
Then, suddenly, 20 minutes ago when I plugged the ethernet cable in to try pinging the ethernet card because I realised I'd never 100% established that it was still in working condition, when suddenly! I have internet. Kind of. It's extreeeeeeeeeeeeeeeeeeeeemley slooooooooooooooooooow.
Is something that I can even ask advice for? I guess there's no way of telling why my internet access was magically resurrected after a week of frustration and despair. Is there any way to help try to restore my computer to running speed? The connection speed is just dire and really limits my browsing & media capabilities (namely video chat). I live really far away from my twin sister and it's shockingly hard to deal with losing my google video chat.
I have Avast installed and up to date, so I don't think a virus could have survived two reformats and a quick check onto cnn and youtube to test connectivity.
I've copy pasted my current ipconfig results below--

I'm also now afraid to turn off my computer in case my connection disappears again.
