To me this sounds either like bad drivers or bad hardware. There is a reasonably easy way to rule out drivers; test it in linux. Unfortunately this card is not supported by the kernel, however there are drivers available on github. You can test this in a "Live Linux" environment, where you do not have to install it to disk, all you should need is a USB stick and some patience.

Given that a T3500 didn't come with WiFi back in 2011, I'm guessing this is a USB network adapter. Maybe try this github repo. https://github.com/cilynx/rtl88x2bu

git clone https://github.com/cilynx/rtl88x2bu.git

https://github.com/cilynx/rtl88x2bu Seems like you have to compile these drivers to get the adapter working. I also have a TP-Link wifi adaptor and TP-Link doesn't support the newer Linux kernels and they haven't added it to the Linux kernel by default so it's a bit of a pain to get this working. But if you can figure it out and get it working congrats lol

Is the relevant information... The issue is the rtl88x2bu driver that is built-in to the kernel... It isn't very good. You could consider an alternative driver like https://github.com/cilynx/rtl88x2bu using these instructions.

If you are running Kali bare metal or if you have allowed USB pass through then it is most likely a driver issue. Take a look at this repo.

You'd first need to tether your laptop to your phone, then install the kernel headers (sudo pacman -S linux-headers), choose the one that matches your kernel version. Then install this driver. It's in the AUR. Make sure you get the one that says "DKMS" on it.
