VPN connection dialogue

I have a VPN connection set up on this PC to access the university's network at campus (through wireless). However, when i'm at home, i get the connection dialogue every time i browse a page on gwg.com.

this is very annoying, cause i don't need to log into my university's VPN to use my homeconnection

i do not know if this is website or client (me) related, but some feedback on it would be nice.

Unfortunately there is little that can be written in reply to your inquiry. You are writing that you are using a VPN via WLAN. Which software do you use for establishing the VPN? What WLAN access point/router are you using? If you have a WLAN access point/router connected to some Internet line, why do you use VPN to reroute your traffic to GWG? Last but not least, what do you mean by "connection dialogue"?

by "connection dialogue" i mean this :

at this moment i am not using any WLAN, let alone VPN, i'm at home on a "regular LAN", with good ol' cables.
The VPN is added to my "network places" because i need it at university, to access the campus' network.
i have no intention whatsoever to use that VPN for browsing at home, yet every time i load a GWG page, the lil dialogue asking me to connect pops up. And that's not only pretty annoying, it also halts the loading of the page (untill i press cancel).

the above mentioned popup seems to appear when GWG loads one of the adservers, could i prevent that server from loading ?
