Hello,

Me and a coworker have two identical W520 machines and both are experiencing exactly the same wifi problems: unable to connect or dropped connections where the status of the connection seems fine, but the computer won't get a DHCP ip address or be able to connect to the internet. Every other machine connecting via wifi or LAN in the office is fine with the router (router is a Dlink DIR 655 http://www.dlink.com/DIR-655 running the latest firmware).

Wireless was working fine for about 2 months on both machines, and sometime late last week or early this week, the problems started.

Both computers are running windows 7 64 bit pro. I have gone through the usual things, updated all the lenovo software using system update, all the latest windows. I noticed lenovo released a big driver update recently which has not fixed the issue.

Anyone seen behaviour like this or know what is going on?

Cheers,

Edit: I will add that the computers have this wireless hardware:

- Intel(R) Centrino(R) Ultimate-N 6300 AGN
- Microsoft Virtual WiFi Miniport Adapter

Both of which appear in the device manager and appear to be working fine from that regard.


Cheers,

Try changing to the High Performance power profile.

thanks for the reply, we are developers and are both always on the maximum performance power profile

I have the same problem on also 2 identical w520 machines with 6300N wifi card. It all started after updating to the latest Lenovo drivers.

Haven't found a solution yet.
