Follow this fix by Lenovo in the mean time: Wireless / WIFI network disconnect frequently
It might not resolve the disconnection problem completely but it should at least lessen the disconnection frequency.
Thanks, theveterans. I followed Lenovo suggestions (I only had to disallow computer to disconnect wireless to save power) helped. Connection lasted about 15 hours this time before it eventually disconnected.
Meanwhile I bought an external wireless adapter, which I should have to do for a brand new computer. I hope Intel is continuing to work on this issue.
Actually, the correct word would be AVOIDED the problem.
- Win 8.1 PRO + Wireless-N 7260 card (NOT the dual band one)
- Connected to AirPort Extreme 5th Gen
- Constant (every 20-30 mins) disconnection to AP
Already tried all (I mean ALL) combination of driver versions, pro tools available in planet earth, including a beta 16.8.x version. None of them fixed. forget about this. Tested disabling BT and a lot of other scnenarios. NONE of THEM will work.
The Problem: Intel's driver for 2.4 GHz, when connecting at "N" speeds has bugs. Current documentation from Microsoft, Intel or HW vendors is awful. That's it. I hope they fix it someday, but it's not the case now.
Solution: Forced the adapter to connect at 54 Mbps (802.11G). Simple as that. It won't give me the performance I'd like, but I stopped dealing with annoying connection loss every 20-30 mins. This allows me to work while Intel figures the bug in it's driver.
How ? Open the adapter settings and set the "HT mode" to OFF (in advanced tab)
Instead of trying to connect at 115 Mbps, it'll connect at a stable 54 Mbps. It works for me (for now).
I left the Wifi mode to 802.11b/g since my adapter doesn't support "A".
Thank you BernandoFortes,
I too am using Apple Airport Extreme 5th Generation router. However, my wirless card is Intel 7260 dual band.
I have driver version 16.6.X installed. Getting frequent disconnect.
Now I have changed the wireless adapter setting to connect only at 5.2 GHz and allow Windows 8.1 to manage wireless profile and not the Intel Wireless Management Tool.
So far connected for over 2 hours, no disconnect as of yet.
I will post the results of this exercise.
