HUB 5 WIRED SPEED DROP

[psycstunt]

Hi Folks

Just upgraded on a new contract and got the Gig1 connection with a new Hub 5.  WiFi is great but on the ethernet connection to my laptop, the speed keeps dropping to < 100mbps (both on Ookla & SamKnows). It is wired with a Cat 7 ethernet cable and the Hub is about 1.5 ft away from my laptop.  Re-booting the Hub solves the issue temporarily, but the problem keeps recurring. 

I am certainly unhappy with this and < 100mbps on a wired connection is way below Virgin's guaranteed mimimum download speed. 

I would be grateful for any advice/ insights etc.

Thanks 

David

Can you try a better Ethernet cable?

Hi jb66

Do you mean a different CAT 7 or a CAT 8?

Anything Cat5e or better should be fine. But they do fail from time to time (usually a wire snaps in the connector) so first job is always to change it to a new one... of good quality.

Also check you network card hasn't dropped to be at 100Mbps - check its set to 1GB - then test speeds again exactly like this.
_____________________________________

As you expect >100Mbps then connect a 1GB enabled computer/laptop, 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 ).

This ensures that NO other devices are connected

Test speeds at https://speedtest.samknows.com/ - 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 on ... see message 7 in the first thread and 9 in in the second and 3 in the third

Hi John 

It appears my Realtek card was the issue? Speed & Duplex was set to auto-negotiation. I have changed this to 1000mbps and everything appears to be working fine so far.  Does that soiund right? 

I am by no means a computer tech so apologies for posting before trying this out!

They copied the same bug from hub 4 to hub 5?

Try another cable

Its unlikely but the NIC could be faulty and dropping link speed

Hi Alessandro

Thanks for your reply. I have a CAT 8 cable arriving today so will try that in the first instance.

Probably not the same ethernet firmware for the auto-negotiate because Hub4 = Arris/Commscope and the Hub5 = Sagem. The UI is similar because LG specifies that to all Hub vendors.

Hi Folks

Sorry for the delay in an update but I have been working. Anyway looks like all my issues are solved with a simple upgrade to a Cat 8 cable. 

Thanks for all your input, it is appreciated.

Cheers
