Can we get a better full set of data. First switch the Hub off for 5' and then back on and go to the "Router status" and check the RS error count columns have all reset to 0.
Then post up ALL the data from the Downstream and upstream pages (x2 tables for each) and the Network logs but DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button a second time).
Then as you expect >100Mbps then connect a 1GB enabled computer/laptop, with up to date drivers, via a known good and working Cat5e (or better) ethernet cable, directly to the Hub which you have put into “modem mode”. Test at speedtest.net (not the App!) to your nearest VM server - try on 2 different browsers.
If they are still low – boot the device into safe+networking mode and try again.
There are many posts on here where unknown software, corrupted browsers or other connected devices are limiting speeds on tests.
Report back what that gets.
