Win 7 WIFI adapter status loged on while not in vicinity of WFI networ

Since a couple of days I have some problems with my Atheros AR9285 802.11b/g/n WIFI adapter on my HP Pavilion dv7 4040ed

First of all every time I am logged on to my WIFI at home, after a couple of hours, I get told that I am loged on to two WIFI networks (A and B), whilst I only get one set of bars in my statusdisplay (bottom right). When I switch off WIFI, network centre keeps telling me I am loged on to WFI B.
A is the SSID and B is the typenumber of teh router I have, so there is only one WIFI signal.
What can cause this and how can I solve this problem? It annoys me.

Secondly, after being logged on to my home WIFI, All activity seizes, I can not load pages, check e-mail, or anything. I can access my router and it tells me everything is ok, but packages seem to come to a halt. My PS3 can be online, so the problem is in my laptop I think.
I have tried releasing and renewing my IP and resetting my router, but only rebooting my laptop helps.
Again, what could cause it and how can I solve this very Annoying problem?

Thank you for your time and effort!

It sounds like to me that your wi-fi adapter has gotten corrupted some how. Try downloading the driver from Hp's website.
