This is my first post on the site, just looking for some help!
I have just bought a new Sony VGN-CS26G/R laptop with Windows Vista and SP1. When i start up the laptop, I can connect to my home internet network wirelessly, however, the internet connection (not the local network) usually cuts out after only a few minutes. I can then disconnect and reconnect to the network, and it will either be perfect for a long period of time or the same thing will happen again and only stay connected for a few minutes (where i disconnect and reconnect again). The same problem occurs when resuming the computer after a sleep or hibernate.
If i try and diagnose the problem using vista, it says there are no ploblems.
When i connect to the router via a wired connection, everything is fine and works great.
To try and solve the problem i have downloaded all of the windows updates, manually put in IP addresses and DNS numbers in the 'Internet Protocol Version 4' Properties, and have changed the power settings to ensure the power to the wireless card is always on.
The router being used is a D-Link DI-524.
I would appreciate any opinions or help
