USB/Wifi problems?
Hello again guys, there seems to be one slightly complicated issue with my PC after a a few weeks of use.
My USB WiFi adapter seems to work intermittently - some days connects to my router easily and other days just will not connect at all. I do not move the PC at all, it is about 4-5 metres away from the router, a few walls in between.
The adapter is the "TL-WN725N V2" and I have downloaded the latest drivers from the TP-LINK website.
At first, I assumed it was a USB issue, as my computer used to crash whenever I plugged in my external USB HDD (Powered by mains) and I had to cold reboot to recover. Also the backlights on my keyboard used to flicker between red and blue randomly (point is whenever I reconnect keyboard it resets itself to blue lights). I realised I had not installed any drivers for the motherboard, so I used the all in one package, NEC USB3 driver and the SATA3 Marvell driver from here:
ASRock > 890FX Deluxe4
This sorted the crash issues with external HDD and the flickering keyboard lights.
But I still cannot connect to the internet consistently :/ One thing I have noticed is that in Device Manager, the devices "USB Controller" (shows two instances) and "Ethernet Controller" do not have their drivers installed. Of course, updating via Windows Update when I had internet access did sod all.
I have also noticed, when attempting to connect to my router, if it does connect properly the signal strength is 4-5 bars before connecting. When it fails to connect, the signal strength is always 3 bars before connecting. When I go to the "change adapter settings" in Network and Sharing Centre, if I'm unable to connect, the status of the adapter is in "attempting to authenticate" and nothing else happens.
Just to note, I have enabled legacy USB in BIOS. If I disable that, the keyboard is unresponsive during POST and I'm unable to enter BIOS unless I clear CMOS.
I'm tempted to think the adapter is faulty, as installing the drivers for the motherboard seemed to fix the other USB issues I'm aware of, but the USB Controller devices with no drivers still indicates a USB problem to me.
Any guidance/troubleshooting would be great, as I have tried everything I can think of off the top of my head (as I am happy playing Just Cause 2 and Amnesia: TDD offline completely fine :P) so I'm not tooo bothered. But my inner OCD wants everything fixed (not to mention updating MSE and Windows Update, not just gaming ).
Thanks in advance!
