The 2800VG isn't known for being the best wireless router out there tho (i've got one) and the draytek forums are full of complaints about that side of it. It's pretty good but it's probably a bit overpriced
IMHO as someone who's had one for a fair old while. The previous series (2600?) was probably better overall and draytek are still trading off that reputation to some degree.
Don't get me wrong - it's a good router - but it's just not as compatible with different wireless chipsets as perhaps it could be (as compared to some other routers i've owned).
YMMV.
