Prior to this thread I have searched online for days.
My link speed when i connect to a router is normal , about 65mbps then after a moment it drops to 5mbps or even 1mbps. The download speeds are less than 100KBps.
I have tried many different routers, they are not the problem.
Even when using wifi file transfer softwares like 'software data cable' the speed is very low , about 100KBps , which used to be 1-2 MBps. So I infer the problem is with the phone itself.
I have tried factory resettimg, flashing stock JB , even stock GB , still no luck.
My friend has an s advance, with no issues. I compared my wifi config files, tried copying them to my phone.Still no luck.
The only other explanation to my problem I got is maybe its a hardware issue.
So guys please help me if i can try anything else software related.
I am sorry if I said anything wrong.
