Note: This is a tutorial on the USB-AC53 Nano Adapter, it is a separate purchase and not included as part of your JOI BOOK 150. The reason for using a USB Adapter, is that the JOI BOOK 150 inbuilt wifi cannot support 5G. The AC53 Nano Adapter does and hence you get high speed wifi.
This is the adapter, for those interested in purchasing the same (however I can't say I recommend it, although it works great in windows, it was a pain to get working in Linux)
Firstly, find the driver we need to make the AC53 work.
The AC53 works on the RTL8822BU adapter, hence download and follow the install settings here
Note: when it's working you'll end up with 2 wifi adapters again (the onboard one and the USB one). I disabled the onboard one by adding the following to the end of the /etc/network/interfaces file. "iface wlx18bb264035b1 inet manual"
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
iface wlx18bb264035b1 inet manual
This means I still have the on board wifi if I want it, it's just I have to start it manually.
Fixing an Unstable WiFi connection.
Only do this if you're really facing issues with the stability of your wifi connection as this fix, uses a different wifi manager, and it don't look pretty at all :(, but it works.
So after a few days running on the AC53, I would find that the wifi connection would sometimes disconnect for no reason, seemed to be more often when I used my phone's hotspot. These are the two changes I made to fix it.
Step 1: Disable powersaving on your wifi adapter, so it has full power all the time. Do this by editing the file: //etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and change the wifi.powersave = 3 line to 2 (note don't set to 0 this will power it off completely)
wifi.powersave = 2Save the file and reboot. If this solves your problems, then great! don't do anything else.
If like me... it didn't then read on.
Step 2: Disable IPV6 (if you don't need it, disable it as it can be buggy on some older/unusual hardware), for me this is the bit the stablized the wifi.
To disable IPV6 edit the /etc/sysctl.conf file and add these 4 lines to the bottom of it.
# Kill IPv6 for the session
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1Reboot and your wifi should now be stable, but you have no IPV6, sorry.
