I'm just throwing this out there as someone's bound to have an answer.
i was recently trying to connect my wireless router to my pc and i messed up somewhere & decided to start over again. big mistake... now my internet won't connect at all, even if i directly connect the cable modem to the pc. I've already tried to release, renew, flushdns to the ip but to no avail. i've even uninstalled & reinstalled the driver, installed another nic card but same result, the internet wont connect. if anyone has any solutions to try, it'd be greatly appreciated.
