I am having some troubles with multiple laptops that where recently upgraded to windows 8.1, all of the laptops listed below have issues connection to WiFi, they can and they eventually will connect, but almost never automatically.
These are the laptops i am having troubles with: NC6320 6710b (GR680ET) 6710b (GB887ET) 6710b (GB894ET)
(All originally came with windows XP Pro and All have been upgraded with an Windows 8.1 Pro x64 operating system and a SSDnow 300 drive from kingston)
Now here are the details; These laptops (lets only speak of the 6710b because that one is most common for me) used to work fine on the wireless network in our company, but as soon as windows 8.1 happened, all the laptops started to have random issues with wifi at start up. 7/10 times when i fired up the laptop it just would not connect. simple solution: rebooting until it did, or manually disable the wlan adapter and enabling it again. Unfortunately i hand these laptops out to employees, who mostly do not know their way with computers, so in that case the employee keeps rebooting until it works. now this is an issue i need to see fixed, so i tried to figure out what was wrong, here's a list of things i have tried:
(note that the drivers below have been tried with windows vista/windows 7)
reïnstalling the driver
moved BIOS settings one by one
deleting the driver and install the 32 bit version
deleting the driver and let windows 8.1 install the driver
reïnstall windows 8.1
replaced the nic with the nic of another 6710b
Switching the wireless mode between 4/5/6 (b/g, a/g, a/b/g) in the advanced properties of the wlan module
installing a bunch of wlan drivers that also can be part of this particular laptop
deïnstalling a bunch of wlan drivers that also can be part of this particular laptop
installed a driver directly from the intelsite
installed the HP Support Assistant
tried installing the xp driver in compat. mode
installed the HP wireless assistant
moved the laptop into a whole new environment (home) where the wifi is mostly untouched (except for SSID and some NAT settings)
also, please note that the systemlogs where clean,..
at the end i was so tired of trying that i created a batch file that rebooted the wifi adapter at start-up. which changed the odds of the wifi working a tiny bit to my advance.
The only thing i could think of was that it had to be the operating sytem, so for the fun of it i decided to install the windows 10 technical preview, but that didnt solve anything either.
Right now the current installed driver on the 6710b (GR680ET#ABH) is: Intel(R) PRO/Wireless 3945ABG (version: 188.8.131.52) and the installed Networkcard is: Model: WM3945ABG MOW2 CT: GB86A0DB6WGHII Intel S/N: [Personal Information Removed]
