Hi! I think I'm going to exchange my old BEFW11S4v2 with a WRT54G or a WRT54GS. I've read and read, but I still have some questions (maybe they're already answered - which I then haven't seen - sorry). It sounds like, some (older) versions (because of other chipsets) have better QoS support than others? Is this true? What should I look for? I need QoS that works (I'm using VoIP)! Which versions of WRT54G can be upgraded to support SpeedBooster? Is SpeedBooster only useable, when having other Linksys products (with SpeedBooster), besides the router - or is it always good? Too me, it seems like I should look for WRT54GS 3.0 (the newest one with 32/8 MB). Am I right about this? As mentioned, I don't know about it's QoS quality. Should I see if I can get on older model? Which one then? Thanks in advance!
