I recently bought a Asus laptop G751JT, second hand from a friend and it works perfectly in every respect. The wifi in the beginning too worked absolutely perfectly but then all of a sudden it stopped. So the problem is that the wifi adapter is the Intel AC 7260, and it seems to now have a very short connectivity range and if I'm searching for networks they have to be close and even when they are close the bars that show signal strength remain on one bar. That's one problem. Further that if I do eventually connect to a wifi, the connection will be highly unstable and connect and disconnect frequently and sometimes just say can't connect. When it eventually connects the speed of the wifi is so slow its almost unusable for the most part. It started by having high ping in games and sudden connectivity loss and overall slow speed. Another problem is that download speed is so slow. If i connect another laptop to the same wifi the speed is fine. The way it seems is as though something is continually using the wifi in the background the the speed is hindered or restricted.
So overall it seems that the problem is that the wifi connection is terrible or something is restricting wifi speed and connectivity. I have done a lot of research and cant seem to find the same issue. I tried to use a TP link wifi adapter which worked until i turned off the laptop and turned it back on then the adapter too, had exactly the same issue. If i use a lan cable the connection works and speed is fine etc so the lan connection works with the same router. I once got the wifi to work properly for a bit once by deleting the driver netwfw02.dat and replacing it with an intel driver netwfw02.dat without going through the driver install process but by copying it manually. This seemed to help until I restart the laptop. The driver itself says its not digitally signed if I install the network driver from Intel's Website. So I font know if it has something to do with how windows installs the network driver if a virus or registry command edits or changes the driver as it installs. I have done many Windows Resets to try fix it and Network resets to fix it all didn't work. Also wifi adapters work until i reset my laptop then they have the exact same issue. Its as though the wifi adapters work until something changes if thast even possible. I have run virus scans from many different programs and antivirus including Microsoft malicious scanner in safe mode. I have done boot time scans and nothing comes up. A complete reinstall of the wifi ac 7920 while in windows doesn't fix the issue unless i delete the netwfw02.dat file then i have poor connectivity to wifi but the speed when connected is fine.
Sorry its so long and probably confusing but the problem has baffled me as i dont even know where to begin the fixing process and I have tried many things none of which seem to have effect. Please let me know if you need anything from my side to help or further explanation. And i don't know if this has anything to do with it but if i install other drivers like a gaming mouse driver the AC7920 stops working and the device manager shows a exclamation in a yellow triangle next to it. I would assume those drivers have nothing to do with each other, and if I install Bitdefender i get a BSOD every 5-10mins and by searching the code it says its an issue with the network drivers or drivers. But with avg,avast or McAfee this doesn't happen. Could my entire windows installation with regard to driver installation be corrupt.
