WiFi Connection interrupted spontaneously on Ubuntu 22.04

I'm experimenting with an interesting problem that started about a month or two ago. My Linux machine can read Wi-Fi signals and I can connect to my home Wi-Fi network. However, after anywhere between 5 to 30 minutes of uninterrupted work time, the Wi-Fi stops (it still shows up as being connected, but my browser stops working -- both Chrome and Firefox).

Interestingly I have also noticed the following:

• Chrome and Firefox can't connect to the internet but Google Meet and Zoom can continue running as if nothing happened. Slack will also possibly halt.
• This only happens with my home internet provider and at my Mother's house (she has the same internet provider), it works fine in other locations eg. at University/Work (with potentially the same/different) providers.
• Internet connection will interrupt spontaneously on my computer (browsing mainly), but my Android phone can hold the connection steadily to the same Wi-Fi.
• There are no interruptions on the internet in my computer if I use my phone as a Wi-Fi hotspot (the same service as my Wi-Fi, ironically). So I find this a bit strange.

Where is the problem in this situation? And what should I try doing first?

It doesn't seem to be an internet provider problem because my phone would have the same issue. It doesn't seem to be my laptop Wi-Fi card either because I can go with perfect internet when I use my phone as a hotspot provider. So I'm a bit stumped. I will see if I can re-install Chrome/Firefox and perhaps that is the issue.

Some extra details of my setup: ASUS Zenbook. Pure Linux Ubuntu running on MATE. No Windows Dual boot. I recall having some trouble when I bought the computer setting up the Wi-Fi card to work (and got it working by upgrading to a new kernel), but it worked smoothly for about 2 years and I'm only having trouble now.

$uname -r6.5.0-18-generic$uname -aLinux alphastar 6.5.0-18-generic #18~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Feb  7 11:40:03 UTC 2 x86_64 x86_64 x86_64 GNU/Linux$lspci [Only relevant network information shown below]01:00.0 Network controller: MEDIATEK Corp. Device 0616

A relevant thread I've also been reading, though I don't think the kernel route will fix this, because I don't get this problem with another network or through my phone hotspot as internet: 22.04, wifi keeps disconnecting for a few seconds frequently

My usual workaround is to just disconnect and re-connect from the Wi-Fi network manually but it's extremely inefficient.

Edit: Not a Chrome/Firefox issue. These were just re-installed.

When the signal comes back after a minute or so,it starts giving:

-- I just encountered a similar problem at a CAFE -- This is the output of $ sudo lshw -c networkWhen it works:
