I'll try to make sense :D

On Xnet Fusion, not currently set up for VoIP (no VoIP hardware)
Currently have Dlink DSL router (ick) and Linksys WRT54G Wireless running together.

Should I add something like Linksys SPA2102 to the mix so that I have 3 devices, or go for an all-in-one unit?
Ping times are pretty horrible in-game currently (750ms or more in WoW) and I'm wondering if I have too many devices to go thru to get my 'net :)

Dlink router is assigned DHCP duties and the Linksys just provides WiFi.

Suggestions people..... I gonna get SOMETHING today
