Odd Disconnection Problem

[Guber]

I can't log into WoW, I type in the password and account name and then it connects and immediately disconnects me. I know I'm connected for a second b/c it says I was when I check my account on the WoW website. This has happened ever since I downloaded the most recent patch (which it says it downloaded completely). I uninstalled and reinstalled the whole game and the same issue persists. I have two computers (desktop and laptop) and WoW works fine on the laptop so I'm going to assume my internet connections are fine. I did everything they suggested on the website for troubleshooting and then when I emailed them they just sent back that same troubleshooting crap from the website. Sorry to be so long winded here, any input would be appreciated. Thx =)

I have had that , usually Immediatly after a router puke , which results in me having to reboot that , then my pc.
my router pukes out resulting in one of more of my pc's losing connectivity to the internet , and at least one being able to stay online.

is your routers firmware up to date ?
have you ensured no firewall is eating data packets going out or coming in?
do you have more than one firewall running ?(sounds silly but i have seen that done before lol)
are there any sharp kinks in the network cable from the desktop pc to the router , or any signs of crushing (cable could be damaged)
im assuming you have ensured all cables are solidly connected , none half out or at slight angles ect.
is your network driver up to date?
seems silly but try pinging blizzards server from the desktop (ofc the laptop is fine so dont do it from there)
compare system settings between the desktop & laptop

sorry this is a bit long winded , just trying to think of what could make your connection die.
