T3 timeouts not good and RS errors may be an issue - so can you do this....
Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax and ethernet cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables. Then switch the Hub back on and leave ~5 minutes
When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) you have a problem (noise) that only a Tech visit will sort.
Re the speedtest - can you do it this way....
As you expect >100Mbps then.... Connect a 1GB enabled computer/laptop (check network card is set toi 1GB) , with up to date drivers, via a NEW and working Cat5e/6a ethernet cable, directly to the Hub which you have put into “modem mode” (https://www.virginmedia.com/help/virgin-media-hub-modem-mode
). Or go into the Hub settings and turn off/disable the wifi and also disconnect all ethernet cables from the Hub. This ensures that NO other devices are connected
Test speeds athttps://speedtest.samknows.com/
- or https://www.speedtest.net/
- try on 2 different browsers - as Chrome sometimes gives odd results.
If they are still low – boot your device into Windows safe+networking mode - to disable any potentially interfering software - and try again.
There are many posts on here (I have a list of ~30!) where QoS software, anti-virus, 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. For examples of why... see message 7 in the first thread and 9 in in the second and 3 in the thirdhttps://community.virginmedia.com/t5/Speed/HUB-5-and-IGB-wifi/td-p/5088163https://community.virginmedia.com/t5/Networking-and-WiFi/Slow-Ethernet-Speed/m-p/5060946#M484321https://community.virginmedia.com/t5/Speed/Upgrade-from-M600-to-Gig1-no-speed-change-with-Hub-4/td-p...
