The latest firmware update for a Hub 4 has broken the link aggregation (LAGG) functionality where a Hub 4 in modem mode could be connected via 2 or more network cables to secure the best speeds.  

If you use LAGG you might try with just 1 network cable from the Hub 4 to your Router.

Hi VM Support

Please could you check my connection, I am getting less them 300mbps constantly even after a power cycle of the hub4, these have been speed tested on Wi-Fi 6 devices ( Latest Gaming PC <Wired> iPad Pro/MacBook Pro and Galaxy S23 ultra ) 

Awaiting your response

Hi @mhussain14 👋, thank you for your post. We're sorry to hear about the slow speeds you've been experiencing 😔

How long has this been the case and have you tried all the relevant standard checks, including rebooting your Hub? 

Advice on fixing slow speeds can be found here 😀 You can also test your speed here and run diagnostics through your My Virgin Media account here, to see if it detects any issues.

Furthermore, I'd suggest going to this link here to set up a 24-hour Broadband Quality Monitor graph. This will allow us to visually see what your connection is doing and it'll assist us in pinpointing where the issue could be coming from on our side.

Please make sure you have the Hub in router mode while you do these tasks. We look forward to hearing back from you.

Regards,
Daniel

Do a speed test in modem mode with PC in safe mode with networking.

Hey @mhussain14 thanks for reaching back out to us on the Virgin Media forums. 👋🏼

I'm sorry to see this issue occur on the broadband connection /network. 😞
Let's investigate further in to this as we can see a massive drop in the connection there.

I will send a private message - watch out for the purple envelope inviting you in.

Kind regards,
Ilyas.
