Wireless Router Repair [Help]

I am using Airlive WT-2000R Turbo G wireless router, for my infinity connection.

for last few days its not working properly, it restarts after every few seconds, i have tried changing its adapter but no success.

I guess its a hardware issue therefore needs repair.

Is there a solution or repairing shop available here in Karachi for wirless routers.

Thanks in advance.


I dont want to buy new one.
