Apologies for another "what router should I buy" thread, but I've had a browse on here for a while and not seen anything which is basic enough for me!
I don't have any particular requirements, other than stability, optimum wireless range, VPN for home working and my son is a gamer. I live in a Victorian semi and need the best reception through 2 or 3 brick walls and a wooden floor. I upgraded to wireless N to try and improve signal strength. Two PCs have TP-Link N cards, the other users are laptops, so wireless G. Oh, and a PS3 since Christmas

I currently use a WAG160N which now seems to require a reboot every couple of hours, so am looking the best bang for my buck in a replacement - not more than £100, but ideally less! I recently switched to Xilo as my ISP.
I did consider a Billion 7300 or 7800N, but am a little confused by references to dual band wireless - I think my main question is would I be better off (i.e. get better reception) with a router capable of using the 5Ghz spectrum?
Line stats from the WAG160N are:

My exchange is Draycott/EMDRAYC, and we're about 1/2 a mile away.
Thanks in advance!
