Bad WIFI connectivity
#1
We've been using ethernet to connect my tinker boards to internet and everything was working fine. Now, we need to have Tinker to be able to connect to internet over WIFI.

The WIFI connectivity is acting strangely.

We first connect my tinker board to WIFI and run a speedtest:
Code:
Testing download speed................................................................................
Download: 5.57 Mbit/s
Testing upload speed................................................................................................
Upload: 7.67 Mbit/s
Information about the WIFI network:
- professional grade router (Sophos AP55)
- ~55% of WIFI quality
- When the tinker board is connected the firewall see a good connection speed (72.2 Mbit/s) then it drops slowly to (6.5Mbit/s) and it sometimes get better, sometimes not. 
- Other WIFI device in the same area (computer, smartphones) have no problems

Software:
- TinkerOS 2.0.7 (first tests of 2.0.8 not conclusive)
- nmcli to establish connectivity 


We did the test with many Tinker boards S and same results. Some devices speedtest are really bad (0.17Mbit/s) and huge ping (29000ms 48000ms). Sometimes it works fine after few reboots.

We're not sure if its an hardware or a software issue, we hope it's a software one.

Very simple to check:

https://www.armbian.com/tinkerboard/

with kernel 4.19.y (also 5.3.y) where improved driver is used. Not sure if it runs better, but its one of your only alternatives. In any case you get better software support as from ASUS.
Armbian. Lightweight Debian Stretch or Ubuntu Bionic for Tinker Board.
