i m getting full download speed with utorrent(above 200 kb/s ).but very slow browsing speed .some times while downloading with browser i get speed like few bytes /s. some sites like yahoo r opening with normal speed .but with google even this site it sucks.i haven't change any setting of modem(D-Link GLB-502T) since bsnl had it set up for me year ago.i reinstalled my system(win Xp sp2) 2 weeks back.& problem has started from that day. i thought cable cut is the reason.then i changed my dns to open dns next day & i got normal speed for 3-4 days.but problem started again after that.i hv also tried tcp optimizer ,but it's not working. i m using comodo firewall & avira antivirus.
