My o2 net download rate jumps up and down quite a lot, from 456kbs to 800kbs.  Also every so often my net disconnects, i was wondering if this could be down to the router itself and if i bought a better one to replace the o2 standard one, will it help with these problems.  If so which would you guys recommend.
