I am using D-Link Wireless Router at home, it was disconnecting me from the net frequently. I guys on D Link India website for solution, they replied back in a day, I provided the necessary details to them (Firmware version, hardware version etc…), in 2 days I got new firmware version file in mail…

Upgraded the router…and everything started working fine 🙂

So one more good company with good customer support which I came across….
