Sorry, I have comcast, I have a Cisco E2000 wireless router, Private Internet Access (sorry I don't know what client means), I'm using windows 7 64bit, my roomate basically reset all the advanced settings to default. It works on my laptop (I don't use a VPN on the laptop). It worked on my desktop with the VPN before but not after he reset the settings. I don't think its a problem with the wireless.. Sorry if thats still vague..
