Acer swift 3 (i5 8250u /GeForce MX150) wi-fi problem, it stops all my network! Help!!

Hello, I've just bought the brand new Acer Swift 3 (with i5 8250u CPU and GeForce MX150 GPU) and I have a big issue with the wi-fi. What happens is that, when i connect to the router, it works properly for about 2 mins, than it blocks every device connected to the router (internet goes really slow, almost stuck). I've tried every solution found on the net (upgrade Win 10, upgrade wireless card drivers, disabled autotuningleve, disabled energy saving options, changed router) but nothing worked. I have bought the PC with a friend (he bought the same model from the same vendor) but he has no problem. Could it be an HW problem?? Please help me, I am desperate, the laptop costed too much to have this issue!!

Updating the BIOS might help. You can download the latest BIOS from here: https://www.acer.com/ac/en/GB/content/drivers

The download file is archived, so you have to extract it before installation. NOTE: Before executing the installation make sure battery is fully charged and laptop connected to charger. During the installation the system may restart several time, so don't turn it off.

If updating the BIOS doesn't help, you should contact Acer in your region, or if your device is still in test period, return it back to the store you bought it from.

Thanks for the suggestion, I've checked my BIOS version and it's already the most updated (1.03). No other solutions before returning it back?

Can't think of any. You have already done the troubleshooting that needed to be done.

Hi,
Could you please try removing the devices connected to router, download the driver from Acer support site and reinstall your WiFi driver and see whether it resolves the problem, could you please post the laptop model( SF314-xx), the driver version and WiFi make.

The model is SF315-51, I have already installed the latest drivers downloaded from the Intel site (which are more updated than the Acer's one) but it didn't work

Hi,
Go to Settings( click Windows logo), click Network and Internet tile, click WiFi in the left pane, click Manage known networks, click if you see any unknown networks( neighbours') and click "Forget", do this for all unknown networks and leave only your WiFi connection in there(like in my snip).

Thanks again for the help, but I live in the countryside and I have no other Wi-Fi connection close to my place!

Hi,
OK, then try this, connect your laptop with Ethernet cable, go to Control panel, Network and internet, Network connections, right click your WiFi, select Disable and then Delete it, reboot and create a new WiFi connection.

Thanks, but this laptop has no ethernet port. Now I'm trying to install a wifi working copy of windows 10 on my external hd and trying to boot the laptop from the exteral drive, if it works it means that the installed version on the laptop is bugged.

Hi,
Give this a try, type "troubleshoot" at Start search, click Network connections and see whether it fixes the problem.

Just tried, getting "No errors found" message, I've never solved a problem with MS troubleshooting.
However this story will finish, I find shocking that Acer and other producers does not test their product before selling them (and the worst thing is that this error is almost impossible to be fix!!!).

I've just finished the test with the W10(already tested and working) running from an external drive. At the beginning it seemed to work, but after 5 minutes the internet connection dropped. I've tried everything, there is no solution, I will return it back to the shop. So bad!
