I'm having frequent wifi disconnects on my Lenovo X1 Carbon Touch laptop.

I got this laptop 2 months back and it has been happening ever since about 3-5 times a day and 10 times a week on average. I've Frontier Fios internet. Power connected or not does not matter.

Once I get disconnected, I try below to connect again in that order:

• turn Airplane mode on and off,
• troubleshoot network problems windows troubleshooter),
• restart the laptop

I'd find that the WiFi adapter would get disabled and sometimes windows troubleshooting would help but more than often I'd end up restarting the laptop.

A week back, I upgraded my wifi network adapter drivers (now Intel, version 15.5.6.48, 10/3/2012). I still get disconnected frequently but turning Airplane mode on and off gets me connected again. So the driver update did help.

Windows 8 is updated.

None of the other devices (nexus, iphone phones, nexus7, ipad tablets) would have wifi issues when my laptop would get disconnected.

config:

Intel(R) Centrino(R) Advanced-N 6205 (WiFi network adapter)
Microsoft Windows 8 Pro Microsoft Windows [Version 6.2.9200]
x64-based PC
LENOVO
System Model: 3443CTO
X1 Carbon Touch

I recently noticed this log message When I got disconnected in event viewer:

Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x[XXXXXXXXXXXX]. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

Any idea?
