[MENTION=13657]farhanmughal[/MENTION]! While in Lahore, you can only consider TWO Services.
1. Link Dot Net - If you live in DHA Area, then LDN might give you better results over PTCL DSL.
2. PTCL DSL - Quite simply the only solution people have here, especially for online gaming.
As for Rest, Qubee, Wateen etc ... Wireless is NOT meant for gaming. Which means, you'll get even higher than usual pings on 'em. (While you are looking for an alternative which should have LOWER pings).
That said, On most of international servers, If your pings are <250 ... Your connection is just fine. If you get higher pings than that, then run a SpeedTest and see what pings you get on different servers. Also run the PingTest.net to get an idea of the quality of your connection.
