I am using DLINK DIR 600L. I bought this after hearing lots of good suggestions from my friends.
My ISP is Tikona and I live in India.
Hardware Version of Router is B1 and the firmware version was v2.00.
When I connect the INTERNET cable to PC my internet works fine ( that points out that there is no problem with ISP ) but when I connect the INTERNET cable to my router (To use wifi and my desktop at the same time) internet connection gets into Limited Connectivity or No connection and stays like that for an hour or so.
After going around through Google i found a solution with upgrading the firmware so I upgraded to V2.04 but the problem still exists. A friend of mine suggested me to upgrade to V2.03 because he had a similar problem and it was solved . But even after updating to V2.03 I still got problems.
Please help me out.
I dropped a mail to DLINK Customer Care here in New Delhi , India.
