Since I have migrated from Windows 7 to Windows 8, my WiFi connection has been a nightmare.

The disconnection occurs a lot of times, intermittently.

I am going to contact Intel since I think Microsoft will not provide any useful information. The latest contact I had with their support about ATI Radeon's driver bug was pretty bad.

I am sharing my info, regarding my Wifi network adapter, and maybe someone can give me some tips to solve this connectivity issue:

Device: Intel(R) WiFi Link 5100 AGN

Location: PCI bus 4, device 0, function 0

Advanced Properties: 802.11n Channel Width for band 2.4: 20Mhz Only 802.11n Channel Width for band 5.2: Auto 802.11n Mode: Enabled Ad Hoc Channel 802.11b/g: 1 Ad Hoc QoS Mode: WMM Disabled Fat Channel Intolerant: Disabled Mixed Mode Protection: CTS-to-self Enabled Preferred Band: 1. No Preference Roaming Aggressiveness: 3. Medium Transmit Power: 5. Highest Wireless Mode: 6.802.11a/b/g

Driver info: Provider: Intel Driver date: 1/22/2012 Driver version: 14.3.2.1 Digital Signer: Microsoft Windows Hardware Compatibility Publisher Driver files: C:\windows\system32\Drivers\NETwNs64.sys C:\windows\system32\Drivers\vwifibus.sys C:\windows\system32\NETwNc64.dll C:\windows\system32\NETwNr64.dll

Power management info: Allow the computer to turn off this device to save power

Connection info: Security type: WPA2-Personal Encryption type: TKIP

The router is Dlink DIR-300. Without any configuration changes since Windows 7, now I am using Windows 8, so it seems there is something weird with operating system or Intel Wifi driver.

In Intel Driver Update utility page, it says:

Product Detected: Intel(R) WiFi Link 5100 AGN

Current Driver Installed: 15.1.1.0

This device is unknown or unsupported. Please contact the manufacturer for possible updates. More information>>

Have there been any changes around nearby WiFi devices? Other APs suddenly online or on the same channel? Do multiple site surveys and see if anything appears. Possibly unrelated to the upgrade to WIN8 –  Dave M Jan 24 '13 at 15:18
    
No changes so far. My wife's notebook is still using Windows 7 and her Wifi connectivity is fine. Mine is unstable since the OS change :-( –  Junior Mayhé Jan 24 '13 at 15:24
