Presario CQ57 unstable wifi connection

Hi all.

As the topic indicates, I have a Presario CQ57 laptop, and am running Windows 7. I am having a problem holding a wireless internet connection. All other computers/laptops on the network have properly functioning connections. I am able to connect to the network, but the problem is that my laptop cannot hold the connection for very long. Every 5 minutes or so, I get randomly disconnected from the internet. This does not show in the wireless connection bars at the bottom right (it does not change at all). If I am in an online game, I will be disconnected, which is very frustrating. Also, if Skype is open it will show the reconnection symbol on the taskbar. I have tried various things to fix it, but I am willing to try anything and everything to fix it. I am new to this, and therefore am not sure what other details should be provided.

My router is a Netgear DG834Gv3 (there is also another modem in the house I can connect to which is a Dlink9A3C, this one does not work properly for me either).

My network adapter is "Atheros AR9485 802.11b/g/n WiFi Adapter" (from Device Manager).

If any more information is required, let me know. Thank you.

 

Thank you for your reply DavidGP.

My Windows 7 does have the service pack 1 update and critical updates have been done. I am not entirely sure if I am using a 3rd party wireless manager, but I think I am using Windows own manager. I am now trying the problem solving ideas in the link you posted.
