The reason why my backup computer was never allowed to replace my older laptop is that I always had troubles with connecting it to wifi through Linux Mint. No Wifi-issues in Windows 7 (which is what it was shipped with), but in Linux Mint it would only connect for short periods of time before disconnecting.
In any case, I installed 18.1 hoping that whatever issues my computer had with LM would have been resolved by now. And the experience has been better than last time. On one occasion my computer was not able to connect at all (finding all networks in my area, but upon trying to connect constantly asking for the nettwork password), but this was resolved after a reboot. For the last three days I have been able to stay connected, the signal strength is good and in general there does not seem to be any issues.
Except one: speed. I did a comparison today between my older laptop (running Linux Mint 15), the one I'm currently using and my cheap android phone (Moto G2), using testmy.net (tested the devices one after the other, all to the same UK server). My network is supposed to be 30/30 Mbps (but has usually been anywhere between 15-30 when testing the speed previously)
Below are the results:
-----------------Old computer (LM 15) | Computer with LM 18 | Motorola Moto G2
Dowload:---------33.3 Mbps-----------------------8 Mbps------------------------30.2 Mbps
Upload:------------20.9 Mbps-----------------------3.9 Mbps---------------------10.9 Mbps
The difference is quite shocking.
Here is the result of inxi -Fxz gives:

I did actually try to install the recommended driver just after having installed LM 18.1. However, after doing so I was no able to connect to my wifi (all networks were identified, just not able to connect) and so I reinstalled LM 18.1 altogether (as I didn't see a way to "rollback" the driver update). (In retrospect, regretfully I don't think I even tried a reboot after having the updated driver give me connection problems.)
Any suggestions? I could try to go for the recommended driver update again, but in that case I would very much like to know if there is a way to "undo" the changes should the same connection problem emerge.
