Hello there! First and foremost thanks for taking the time to read this - this will be a help request.
I've spent the past two months dealing with the poor performance from the Intel Dual Band AC 7260 that came with my G761JY-DB72.
Background: At first, things seemed okay and I thought I could tolerate the slowness of the card as I wasn't gaming much and wasn't downloading much either. However, lately I've wanted to game and download some new games, but I'm getting only 500-750Kb/s download rates through steam and 500Kb - 3Mb fluctuated download speeds through firefox. I simply can't take this anymore.
I've read the forums searching on here for the past few days before posting and I've tried the following to fix the AC 7260's speed issues and general issues with the G751JY:
1. Turned on the laptop and noticed the awful warming of the display... wonderful.
2. Windows 10 update from 8.1 failed, had to do a fresh install... yay!
3. Finally got Windows 10 installed on the G751JY and noticed the slow download speeds. Calibrated my display and removed splendid to fix the warming issues.
4. Compared my G75VW's speeds to the G751JY to ensure it's not my router. The G75VW gets a steady 5-7MB DL rate on steam, G751JY gets a full 500-750KB.
5. Tried to update the AC 7260's drivers from Intel, had to system restore as the application would not run on my system. The driver would be uninstalled and Win10 would be left without a wireless network driver. Wunderbar, just wunderbar.
6. Completely wiped Windows 10 (again) yesterday after searching these forums and noticed the guide with the proper installation order for the drivers and programs. Things seemed to be okay at about 1AM downloading some files with a 5-7MB/s speed.
7. I noticed this afternoon to evening the slow 500-750KB/s speeds are back and nothing is fixing this.
8. Ran ping tests on google to ensure I'm not crazy and am experiencing fluctuations in ping as well as download speeds... Google's ping test confirmed it. Every 5 pings I get a good 200-300ms series of pings.
9. Searched forums some more, noticed a thread saying to try a regedit: add ScanWhenAssociated to HKLM/System/... It didn't work, still getting fluctuations in download speed sometimes now up to 3MB then back down to 500KB. Google ping tests show high spikes still... groups of 200-300.
10. Searched google for AC 7260 replacement cards, can't find anything pertaining to the G751JY.
11. Searched google for AC 7260 / DIR-645 connection issues, couldn't find anything...
So, here I am. I'm trying, but I'm losing it. Does anyone know of a replacement card for the G751JY to get rid of this god forsaken slow connection? Or even better, has anyone found a fix for this?
And here it is again, my system info:
G751JY-DB72
Windows 10 Home
Intel Dual Band AC 7260 Wireless Card (18.12.1 Driver Install from 8/17/2015)
