Wifi connection issues

Michko

Hello, last half year i got serious problems with my internet, really low download speed and stability issues, after lot of asking and getting the same answer I sent my Aspire VN7-791G to repair service. They told me, they found the problem and replaced my previous Wi-Fi adapter ( I believe it was something Qualcomm, but dont remember the exact type) with Inter Dual Band - AC 7265. After I got notebook home, I updated my drivers and nothing changed. I was thinking maybe it was unlucky, so I switched my notebook for a few days with my brother. If its going to crash for him aswell ( He has room next to Wi-FI router) After few days he gave it back to me and said Wi-Fi was unstable and slow. I had no issues with his notebook. So i sent it back, hoping to repair it or to get money back(but thats not happening) but they told me they didnt find any problems and they sent it back home. So im here, I literally cant play any online games, watching serials or youtube is pain in *****. I dont know what to do.If I send it back im gonna waste another week without ntb, but at the other side, my guarantee on this ntb is ending in few months.Could anyone help me, how to solve this, or atleast make Acer give back my money? Thank you

Hi,
Go to Device manager, expand Network adapters, highlight and right click Intel AC7265, click Properties, go to driver tab, find the version and let us know.

It is 19.51.7.2

Hi,
Go to Acer support site, download driver version 18.12.0.3 and install it after uninstalling the current driver in Device manager.

Hi,
OK, go to Device manager, expand network adapters, highlight and right click WiFi, click Properties, go to Power management tab and remove the tick from the box that says "Allow the computer to turn off...", also go to advanced tab and try different Preferred bands, you can select them with the drop down arrow.

I already did this, nothing changed

Hi,
I can not think of any more ideas, you have to wait for someone else to chime I'm.

Okey, thank you for your effort.

Hi,
You could also try switching to different DNS server, like Open DNS or google DNS. Go to WiFi Properties, IPV4 Properties and use the addresses as follows:
For Open DNS: 208.67.222.222 and secondary: 208.67.220.220
For Google DNS, use the one in my snip.
