Acer Swift X SFX16-61G: Poor performing Wifi

The Wifi adaptor RZ616 performance is very bad. While signal is 80-90%, the web pages take long to load and adaptor totally loses connection in areas wifi signal strength is lower than 72db. This does not seem alright as all other devices keep strongly working in same location.

Here are results:

    Check the latency of your WIFI link, the problem may be your ISP, you cannot compare Androids with Windows network (Other devices?)

    Run these 2 commands to check Timeouts and Packet loss (both should be zero on a well maintained 4-5G WIFI network)
    ping -n 10 community.acer.com and tracert community.acer.com

    @tgab The fact that your signal strength drops from 85% at 2m to 82% at 3m and drops even further or drops out in an adjacent room suggests to me that the problem is with the wi-fi adapter aerial. By way of comparison, my connection sits at 90% anywhere up to 6m away in the same room and only drops to 87% in an adjacent room with an intervening brick wall. Maybe it's just a loose connection on the aerial. I don't know the details of how the aerial is connected so can't help there. Maybe someone more knowledgeable or with access to the service manual can chime in.

    However, before trouble shooting the aerial, I'd try a few other things.

    Try changing the connection from 5GHz to 2.4Ghz. 2.4GHz provides a stronger signal albeit with possibly more traffic.

    The other thing to check is whether your modem supports 802.11ax. If your modem is older, it may not and that can cause connection issues in some cases. If your modem doesn't support 802.11ax, try changing your adapter interface setting to use 802.11ac instead. That helped in my case when I had an older modem.

    Thanks for your replies. It seems there is issue with wifi card and I will be heading to ACER service center next week. Could not open back cover myself as it could void warranty.

    Yeah, warranty changes based on your country, so we can't guess whether it would be affected or not. It sounds more like one of the antennas isn't physically connected to the WLAN card rather than an issue with the card itself, but Acer will get it fixed for you.
