I have a toshiba satellite laptop with an external Linksys wireless card which connects to triband through my D-Link wireless router. For the last couple of months, I have been experiencing frequent drops in connection. MTNL as usual said evrything was fine at their end. I used a company laptop at home and had same issues, so it's not a problem with my laptop/linksys card.I tried reseting my modem to factory condition using the menu and sometimes that seems to solve the problem. At other times, if I physically reset the router (using the reset button at the back), it seems to solve the problem but there are still connection occasional connection drops. Now I suspect it's my router's fault combined with a bad MTNL line. Any ideas/suggestions on how to resolve this. Thanks in advance,Claude
