Windows 7 - Lenovo Broadcom wireless problems.

Hi there,
Not sure if I've got the right forum so sorry if I've put it in the wrong place, but here goes:

I'm running a brand new Lenovo B570 with Windows 7 Home Premium x64 and a Broadcom 802.11n wireless network adaptor.

Earlier today I was managing to connect to the internet wirelessly, though the connection kept dropping out. Then I could connect to the wireless router, but not through the internet, and now I can't connect wirelessly at all. With an ethernet cable internet access is fine, and another computer in the house connects fine to the wireless too, so it follows that the problem's with this machine.

The computer recognises that the networks are there, but it can't connect.

Any help would be appreciated, I've been at this all day.

Hi orderfromchaOs, welcome to the forums , Have you got the correct drivers installed ? Visit the Broadcom site and download the correct drivers if needed Broadcom.com - 802.11 Wireless LAN Solutions

Hi. I tried the update driver button in the network adapter configuration window, and it informed me that the driver software was definitely up to date.

Also, I'm not sure which of the links on the page you showed me I should download.

follow the model # of your adaptor and then select the driver required
