Wanted: Any freelance IT guys willing to offer your services..?

Name resolution aint the problem here - sustained download speeds are crap, name resolution issues would only either cause a download to fail or take a long while to start - they dont have any bearing on the actual throughput once a transfer has started.

As Hippy has mentioned this looks very much like a line problem - if it were the router having issues you would also (normally) expect greater latency and packet loss while it struggles to proccess packets. Latency looks fine so either someone/something is using up most of your bandwidth or your SP has throttled it/is having issues.

V doesn't mention downloads, just says it's slow and losing connections

Latency/ packet loss.... slow browsing, losing connection??

i think she should leave all angles open for investigation.. give this thread some legs!
