Can anyone tell me if I can use this with xnet and vfx?

I purchased it last week thinking I will just use my existing modem to connect to xnets standard dsl and use the Belkin N1 for wireless.

However after looking at the Xnet site I saw they provide the VFX service which I like (I am moving into my own place in 8 days so thought I would join up)

Would I be better off selling that and buying a Linksys WAG54GP2v2?
