Hi guys,
I have an Acer Aspire S7 392 and have experienced WiFi connection problems since the moment I took the device out of the box. First there was the frequent disconnecting from my router, then there was the incredibly slooooow connection speed. After reading through this entire forum I have tried several things.
With the drivers in between 16.536 and 17.05 I had horrible, horrible connection speeds. Sometimes my download wouldn't even go above 2 Mbps while standing directly next to the router. Given this frustration I have let my actual work slide and decided to find out what is actually helping me. (The clueless Acer customer service told me the problem was probably with my "wifi antennas" and I should send it in to repair.)
What works best for me for now is actually to revert back to the Driver Version 16.536 where I get the highest speeds.
I have uninstalled my drivers to version 16.02 (or something like that). Then I restart my computer and the drivers automatically update to 16.536.
I get the following test results:
Driver 16.536 with HT modus on (Best)
Driver 16.536 with HT modus off
Then I upgraded to the new driver version in hopes of actually getting better speeds. But no.
Driver 17.05 HT Modus On UASP on
Turning off UASP helps, but not as much as the old drivers
Driver 17.05 HT Modus On UASP off
And just for completeness sake
Driver 17.05 HT Modus Off UASP off
I will keep testing and see if the connection drops keep occuring in this old driver version or if bluetooth is in any way affected. Regarding the Wifi speed there seems to be some clear ****-up between the 16.536 version and versions afterwards. I haven't moved the computer and just the different driver makes tremendous differences in speed. I spent 5h on this now. Please intel, you should be able to solve this. Buy some computers with the known issues and do some testing...
