Wireless Signals Too Weak

Hello experts,

I bought my Sony Vaio (Model - VPCEH25EN) around 6 months back. I faced some issues with my hard disk having bad sectors a month back and it was eventually changed under the manufacturer's warranty.

Immediately after I received it back, I started facing issues with my wireless signals. I used to receive full signal strength earlier, but now I was just receiving 2 bars out of 5. This meant that my wireless kept disconnecting again and again, and when it did not disconnect, I received bad speed. The issue is still persistent.

When I try connecting other laptops at my home through the same wireless router, it connects well with full signal strength. This clearly shows that there's nothing wrong with the router, but something with either the drivers of my Atheros AR9285 or with that itself.

I have Win 7 Home Basic 64 bit running on my system. Also, I have installed 9.2.0.427 drivers for Atheros AR9285. Please let me know if any other information is required.

Can somebody help me with this?

Thanks,
Prabby

 

Check if both antenna leads are actually connected.
Also AR9295 is crap- it doesn't work properly with 802.11n networks so change yours to 802.11g just for testing.
It may not resolve disconnecting issues as these seem to be related to poor signal reception but it should help you with low speeds you're getting while you're connected.

 

Thanks for the reply... I'll test it and come back...
