I have this laptop http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en...
Its Atheros wifi adapter s very weak. When i was having my old laptop I was able to sit in my room with excellent internet signal, but with this new laptop the signal is weak. I tried to reset my DLINK router. Nothing happened. Tried new drivers. No help. What should I do? Can I overclock this adapter?
Have a check to see if the router you are using is an N standard router, the laptop supports the N wirless feature wi-fi standard in the laptop. it may be the case if your router can broadcast an N signal it is not turned on, but more likely set to a lower standard like 54g.
If you can up the routers broadcast signal to N you should get a better signal and a faster wireless transfers.
You will need to login to the router to change the wireless settings and change the broadcast standard to N if the case.
