Speed slow for a few days now

[markmcg]

Hi,

I have turned off/on modem (Hub 4) and still get relative slow speeds.  Upload is unaffected...supposed to be 1G.  This wired.

Any ideas please? Supposed to be 1G

Is that test on an ethernet cable connected device or over wifi ?

[markmcg]

It is wired...had 'full speed' a few days ago.  Will do some more testing later. 😐

In modem mode, linked to a Netgear RBK50 Satellite Mesh and 2.5Gbs switch...will put Hub 4 back to modem/router and testBack to top with just one PC. 😐

First suspect is a failed ethernet cable -usually a snapped wire in the connector causing a drop back to 10/100 speeds.  Or the Netgear auto activating its QoS.

Try a new Cat6a one (better shielding from crosstalk and interference). If it is still the same do this..
_________________
As you expect >100Mbps then Connect a 1GB enabled computer/laptop, with up to date drivers, via a NEW and working Cat6a ethernet cable, directly to the Hub which you have put into “modem mode” (https://www.virginmedia.com/help/virgin-media-hub-modem-mode ). This ensures that NO other devices are connected

Test speeds at https://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 third

Looks like it could be the known Hub4 94M issue - try changing the Ethernet port on the back of the SH4.

Changed port, rebooted...getting near 900mb. I know I can never get the advertised speed due to the router, at least it is better than 94mb. 🙂
