I like the idea of the dual band but unfortunately I don't think that will work for me as my laptop won't work on 5ghz (unless I get a dongle - which I really don't want to and I'll probably loose within a few days anyway!). Which would mean I'd still be mixing N and G.

So going to go with the TPLink running at 300Mbps, that should allow my laptop to run at it's near full potential of 150Mbps even with a few G devices connected. And my main media PC will hopefully run nearly close to it's theoretical 300Mbps - even running at a 25% reduction to the G connection (no idea if 25% is realistic) I'd still have a significant upgrade from the rubbish I have right now!!

Thanks for your advice
