Intel Wifi Link 1000 BGN Connection Difficulties

Hello!

Something of a frustrating problem here:

I use a Lenovo Y560 laptop with an Intel Wifi Link 1000 BGN network adapter. I've typically
had little problems connecting to wireless access points until two weeks ago. After a bit of
trial and error I realized that, though the adapter detects all the networks it used to at the same
signal strengths, it's unable to connect to anything that's basically not at full signal strength (pretty
much beside the computer). I've tried re-installing the manufacturer's drivers, installing Intel's drivers
(which for some reason cause the adapter to be shown as an Intel Centrino-N wireless adapter rather
than an Intel Wifi Link 1000), disabling 802.11n mode, disabling the "Allow computer to turn off this
device to save power", ensuring that transmit power is at the highest, roaming is at medium, switched
through channels... nothing. Performance is exactly the same, basically bouncing off access points with
four bars or less of signal strength. I've tested this on APs with Open, WEP, and WPA2 security, reset routers,
etc. Verified the actual adapter, seemed well connected, cables were in place. Any ideas, because it's driving me
a little bit nuts how though the networks are detected, connection's not possible. Thanks!

    My issue of not being able to connect was limited to whenever I would try to use my router in "N" mode, i.e. turning on WPA2 (AES) security...was not having ANY issues with wireless B/G using WPA security...but as soon as I would change the security to WPA2 (and bumping max speed to 300 mbps)...BAM!, unable to connect.

    After reading this thread i got the idea of turning OFF the 5.0 ghz radio in the router, and voila, it's now working!

    Not sure why, but perhaps this NIC is "confused" (as someone else in this thread stated) by the 5.0 ghz radio...

    Anyway, it's only been a short time that I'm working, but I noticed a 180 degree turnaround when I turned off the 5.0 ghz radio.

    Try it if nothing else seems to be working for you.
