Waddi i have a DSL for VM
the only real diffrence is that you need somthing to dial up if your going via a telephone line. So if that's your set up then you need a ADSL to dial up and make the connection / conversion.
As my connection is direct to my set topbox, then my set topbox acts as a modem so i dont need that part of the equation. That's it in its simplest form.
If youre in any doubt, call your provider if in your case its Vergn Media, you will be told, we dont support any ask the vendors. But bare in mind if your going wireless you need a
reliable wireless router / adsl or dsl or what's the point.
I guess the likes of NETGEAR LINKSYS do well is because they will help you with a problem. I was on the phone (fee call) to Linksys talking to some chick in the philipeans at 2am configuring my remote access points (Software glitch) point being there was support there when i need it. As it was also them who told me the correct configuration for virgin media
Hope that helps.
