Wireless network connectivity issues

Hi guys and girls..

For past two weeks I am trying to solve issue involving my PC and very slow internet/router response time. The issue involes only one PC as any other device at home have very good response time.

Router is a G+ Belkin
I got two adapters - one is a Belkin G+ adapter from the router , other on is brand new TP-Link N+.

Regardless of the adapter I use (cable connection unavalible) I am connected to a network but my pings are around 600 to 800 or higher.The signal strength is 5 bars(96%) on TP-link and on Belkin 3-2 bars. Even if i am trying to get to my rotuer page 192.168.2.1 it takes very long time (256 ping ) .Installed new windows with new drives , that didnt help. Ubantu wont even connect to the network.
