Acer Swift 3 SF314-43-R2YY sound delay problem and Wifi connecting problem.

Hi! I recently bought a new laptop which is Acer Swift 3 SF314-43-R2YY. Everything was fine until I notice a little sound delay when playing a video. The delay is like few milisecounds, but it is still annoying because I can notice it and doesn't feel comfortable. I tried to play the same video on the other browser but same result. I tried to update the drivers but didn't fix it. I thought the speakers were the problem but it wasn't and I notice that by connecting to my bluetooth headphones and it had the same delay. That is when I notice that the laptop system it self has a problem. I really tried my best to solve but I coudn't. People that have the same laptop model as me has the exact same problem. Is there anyway to fix it?

The wifi problem is pretty simple but I don't know how to fix this. There is a problem with connecting to wifi when I start up the laptop. It takes about 30sec to just automatically connect but it says "No wifi" or "Not connected". Then it tries again to automatically connect, but suddenly the wifi it self disappears from the list and comes back seconds later then repeats the same message "Not connected" I tried to disconnect and connect again, and it worked. I can do it this way but disconnecting and reconnecting everytime I start up, is pretty annoying and irritating. I want this device to connect the wifi quickly and automatically. It is little bit odd because occording to the specs it has wifi6 card and should be fast and quick to connect.

    IIRC your model comes with either an Intel AX201 or a MediaTek MT7921LE WiFi/Bluetooth card. Have you checked for updated drivers from the manufacturer? I know the drivers for my AX201 from Intel are much newer than the Acer versions, though Acer caught up some when they released W11 drivers for some models.

    The latest AX201 Wi-Fi & Bluetooth drivers can be found here:
    Intel® Wi-Fi 6 AX201

    I'm not sure if it's the latest but a very recent (04 Apr 2022) driver for the MediaTek MT7921 can be found here:
    MediaTek MT7921 Wireless Lan Driver for Windows 11 (Version 21H2 or later), 10 (Version 1909 or later) - ThinkPad L14 Gen 2 (Types: 20X5, 20X6), L15 Gen 2 (Types: 20X7, 20X8) - Lenovo Support CH

    Simply download the .exe file(s), run it with admin privileges and follow the prompts. The MediaTek driver page has a readme file with full installation instructions.

    I have the same problem with my Acer Swift 3 SF314-43-R06N L AMD RyzenTM 5 with MediaTek MT7921 for wi-fi.
    Bought the laptop for a week, been busy and realized something is off with the wi-fi connection. Tried to checked using my old Dell laptop but out internet connection seems fine. Installed and updated all drivers but still the same. I googled MediaTek MT7921 and found out it has a lot of complaints. Imagine, my spotify web player keeps on halting, a SPOTIFY that streams 3-4MB  per song, that is totally unacceptable. What's even worse is I can't find a wi-fi dongle that supports Windows 11.
    Mediatek should recall their products.

    Different SKUs of the SF314-43 models had different WiFi/Bluetooth cards. They all use the M.2 (NGFF) 2230 specification, so you can swap to a different vendor if you wish. I used to work at Intel in their network products division (a long, long time ago) and have a soft spot in my heart for them, so I suggest swapping out the MediaTek for an Intel AX201 or AX210. Some of the SF314-43s shipped with the AX200, later with the AX201 but they had stopped production before the AX210 was released. AX201 is WiFi 6, AX210 is WiFi 6E.
