Resolved slow wireless d/l speed problem

Yes, wireless d/l and u/l speeds are now typically 6400 kbps and 500 kbps and, additionally are a lot more steady. Plus they seem unaffected by cordless phones, phone lines to TVs or microwave ovens.
How did I do it? I just changed the router. So, it seems the previous one may have had a hardware problem.
More detail is provided in the forum thread I started on this yesterday.
