Zorin lite 16.2 WIFI issue,and the crazy things we do for our mothers

Hello to everyone,and thanks for your time!
I am a Kali and Minth user on daily bases,so when my mothers elderly 10-ish years old,Samsung laptop started to freeze i thought it would be a great idea to relieve the hardware with a light OS,and here we are.
Zorin works great,response as expected,no issues at all except the WiFi speed,which is about a fifth of the real bandwidth at download,but strange enough,the upload is at full.
The specs are as follows:
-CPU AMD E2-1800/memory 6GB/HDD 500GB/GPU Radeon HD 7340
So what have i done so far in the last few days,except fresh install the OS?
-tried to convince my mother to buy a new laptop,that didn't work
-done update and upgrade
-disabled bluetooth,avoided any use of VPN
-WIFI power management directly disabled (value 2)
-fiddled with Firefox,not much improvement
-installed Brave browser,slightly better
-emulated a VM Zorin on my Mac,WIFI was acceptable
-also installed OS on a separate partition (third device) works just fine
-connected directly thru UTP,no improvement
-the plan is fiber optics unlimited 200/20mbps
-tried on some different networks,same issue.
Below i will share the lshw and lspci data,so knock yourself out,and hopefully together we will find some solution,because i am running out of ideas...

The vast majority of the time, if your Upload speed is normal, but down speed is slow - you need to check your router. If there is any block or interference between the computer and the router or the Router Bandwidth Channel may need to be changed.

I think based on your use-case, Linux Mint Xfce or MATE would have been a good way to go. You get automatic updates and the newer Xfce desktop 4.18 or MATE's recent desktop. Plus Mint sort of has the same paradigm/flow for the most part on all 3 desktops (Cinnamon, MATE, & Xfce). I use Zorin Core about 40% of the time with Mint Cinnamon and LMDE 5 too about 40% with Windows 11 and Tuxedo OS the remaining 20% of the time. Despite like using Zorin a bit more, I think Mint is just a bit better in some areas with regard to their upgrade tool and automatic updates as part of their system. Plus, Mint has found drivers for me in the past with a minimum of fuss. All I am trying to say is although Zorin Core is better for me, their Xfce Lite version I think is not as well done compared to Mint's Xfce which is delightful to use. Good luck!

The latest Mint XFCE is version 4.16.

I didn't want to go long and wide in my description,but ofcourse i checked the router,reseted it,accesed it to check if there is some rogue parameter ...

I downloaded Mate,and will give it a go,so i will check back with the results.

Nope,same thing. All went by the book,no hiccups but the issue is persistent in Mint too.
I already started browsing for a red Samsung laptop,because i am out of ideas.

Will try,but i am not expecting a lot of a ten years old laptop.

But - the newest update will have 4.18 which is in Beta now.
