Have you tried a new Cat5e/6 cable? Old ones can fail and limit speeds to <100Mbps. Also see what the NIC card is reporting in its settings as connection speed? Is it showing 1GB or dropped to 100Mbps? Are the NIC drivers up to date? if all looks fine do it this way in modem mode... ________________________________________________________________
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” (see VM website for “How To”). Test at speedtest.net (not using their App!) to your nearest VM server - try on 2 different browsers.
If they are still low – boot the device into windows safe+networking mode and try again.
There are many posts on here where unknown/flaky software, old network card drivers, corrupted browsers, bad cables or other connected devices are limiting speeds on tests.
Report back what that gets. ---
