My X1 Carbon Gen 3 is a new machine and it's worked fine on a various Wireless APs, but at my mother in laws, her TP-LINK is throwing me off every so often.

Firmware Version:	
3.13.13 Build 120605 Rel.38634n
Hardware Version:	
WR1043ND v1 00000000

Other wireless devices are fine.

Many thanks,

Please try the latest version of the firmware:

I installed it. http://ix.io/grr How do make sure it's running? What do I grep for and where?

Here is another log when I'm unable to join the TP-LINK at all with "No association and the time event is over already..."

Btw, I am pretty sure this is the AP's fault, since when I reboot it, things are much better. However since other devices are stable on this AP, this is still very much an issue for Intel. ;)

oh you are running 3.18 so that won't work.
You must have 3.19 for -12.ucode.

But now that you are saying that rebooting the AP helps, yeah - it must be the firmware dropping the beacon of the AP because it is botched.

Not much I can do for that.
Please try to check for a better / newer firmware.
You can try openWRT maybe.

Er, how come every other device on this AP is OK except my new Intel hardware?

So I need to tell folks Intel software is not as robust as anything else? :/
