I don't have anything running on N speed around here, but I've seen a few posts around that have to do with the same problem as yours. The only solutions that seem to work is is lowering the encription to a level where it will work. I know that would be just a workaround if it did work, but we'd be able to narrow down the problem somewhat.

I couldn't find the bios setting.
What i have under the bios is Network -> Ethernet LAN option ROM (enabled) and ->Wireless LAN and WiMAX radios (ON)
there are no other settings for network.
The problem persists whether I use the adapter or battery.

I keep forgetting that older machines have more options in the bios. You're right, your settings are okay in the bios. Are you using access connections or windows connections? If you're roaming around a lot and using a lot of different access points, perhaps you should let windows handle the wireless.
If you're using access connections, then you should make a profile for each access point you connect to and then when you're at that access point, open access connections and click the profile for that access point.

thanks for this hint.
I just updated my BIOS an WLAN driver to the current versions and gave the N-Mode a try again.
Still the same problem.
For me (paranoid one) it is better to disclaim on speed than on security. In the mode b/g it works acceptable the last weeks.

I'm using windows connections. In any case, the profiles I use have already been entered into access connections.
Any more tips before I have to physically hand it in to a specialist?

The only other thing I can think of is open the network and sharing center and on the left change adapter settings. From there right click your wireless connection and click properties. In the next window, click configure, and then advanced. click roaming aggressiveness and make sure it's medium or medium-low. Then in transmit power make sure it is highest.
I'm not sure what the setting throughout enhancement means. mine has no problems but it was disabled and I enabled it just to see if it made any difference. I don't know yet whether it did or not.

I have got the Edge 15 last week. It has Realtek b/g/n wireless PCIE installed. It works fine until I have installed the Windoes 7 SP1. The sympton is that after the sleep, the wireless will not connect. Disconnect/reconnect does not help. I have to disable and reenable the adapter. Of course a reboot will work. It has the driver from the Lenovo web site installed which is version 2010.
I did a wireless packet trace and it turns out that the laptop only sends out Probe Request with no Association Request at all which means it does not even tries to conenct to the access point. It is definitively a driver issue. Then I installed the driver directly from the Realtek web site:
The driver version is 2020.1.0311.2011 published on March 22, 2011. So far it works OK. Did a couple of sleep/wake, everything seems to be fine.
