Hi all.
I have been using XNet VOIP for a while now, and I'm very happy with it. But I'd like some advice on the hardware. I initially went for a WAG54G, based on the presumption that an integrated router/adapter would handle QoS and other such issues transparently, and probably better than separate devices ever could. Certainly, I've never made any changes to QoS settings, and I've never had any issues. But I'm now feeling a bit stifled by that initial choice; at some point I'd like to upgrade to wireless N, and it would be nice to have some of the features of dd-wrt on my router, which isn't an option with the WAG54G. So I'm considering switching to a separate VOIP adapter such as the PAP2T so I'm then free to use any router I like. But I'd like to know more about what issues I'm likely to face in relation to things like QoS. Will it just work nicely out of the box? Or will I have to tweak it myself in order to get a similar experience to what I get now? If so, are there any good guides available?

Any advice would be much appreciated.
