I hv checked with both it is same but if i connect the isp cable in my laptop speeds are arund 90mbps..

Run a speedtest from your laptop connected by cable on the OpenWrt.
While it is benchmarking use ssh to connect to the device and run the command top -n 5

Use the "Preformatted text </>" button to paste the console output here.

The text was changing when test was going on so I hv put values which came at last..

But I hope the speedtest was still running when you copied the text, right?
Anyway cpu doesn't seem to be stressed.

Yes.. can you suggest any solution??

Since you have a 200Mbps connection and the C60 only has 100Mbps ports, I would advise to get yourself a more capable router with Gigabit ports.

But still i should recieve more speed ~50 mbps instad of ~10 mbps.

Yes, you should. The question is are you going to troubleshoot what might be the issue and get half the speed of your connection or start clean with a device capable of saturating the current and future speed of your connection?

Actually I want to try to use this router only can I revert to tp link firmware??

I don't see any specific instruction in the wiki.
This one seems to have done it.

Given that the restriction to 100 MBit/s ethernet is hardware side, the OEM firmware won't be able to cope with the given WAN speed either.

Actually there is a modem to which this router is connected to provide net on 2 floors.

Doesn't change much. Still you are limited by the 100Mbps port of C60

I tried this method but it didn't work..:confused:
