The signal from my router reads as poor of the time and occasionally comes up as excellent which is what my desktop's signal is. I'm guessing that i may need to replace the wireless card but i don't have much experience with laptops so i'm not sure. HP Pavilion DV2000 Intel Pro Wireless 3945ABG
even though it is showing a poor signal is it still letting you surf the internet? My wireless card on my laptop does that occasionally too but it still works without any issues.
