So I check my download speed every few days to make sure I get what I am paying for, Samknows real speed would usually come back with around 1140 and 940 - Ookla would come back with around 940Mbps too. During all this the upload is a constand 52Mbps.
Noticed things going slow on Sunday and the speeds had dropped to around 94Mbps download.
I have two different 1Gb network cards in the PC and swiitching between those (and SH4 ports) made no difference.
After a couple of power resets of the PC and Hub4 all went back to the expected rates. I suispected the PC had got intob a weird state.
During yesterday I could tell from download speeds that things were not right again - and they were back to 94Mbs download and 52Mbps upload.
Tried the power resets again and still 94Mbps download via Ethenet. 5GHz Wifi is still working at over 300-400Mpbs which has never changed.
I have another device with a 1Gb card which would give similar speed results to those excepted - but that is now maxing at 94Mbps download too. A few other devices would usually achieve over 130Mpbs - and are all maxing at 94Mpbs too.
One device I could always get around 300Mbs download via Ethernet is now showing 94Mbps too - but still 300Mbs when switched to Wifi.
It seems the SH4 is auto-negotiating at 100 and not 1000 on all four ports. Config still shows 1 DOCSIS 3.1 channel connect and config download is still 1230000450.
Have done a pinhole factory reset and before doing any SH4 customisation I tried again and still only 94Mpbs on all four ports.
I am sure it is not a signal issue as Wifi is good and I'm getting between -1.1 and +3.0 on all power levels and between 37.3 and 38.8 on all SNR.
I've not seen anything in the logs to show a firmware update but the logs were lost here in the factory reset - currently cmreg-vmdg640-bbt076+voc-b.cm
I will call TS today and get them to suggest things but I can put the issue down to the SH4.
Power levels are mainly the same after the factory reset so within expected range.
Anyone any other ideas of things to try?

I am also having the same problem and need to reboot the modem to fix it until it reoccurs.

Hi there samosa,
Welcome back to the community.
Apologies for the service issue, can I ask whether an area fault has recently been raised in your area?
Also are you able to post network logs for us to check, to do this;
• Please go to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode),
• Don't log in, click on 'router status'
• Copy/paste the data from each of the tabs as text into a 'REPLY' as opposed to 'QUICK REPLY'. Please do not include your MAC address.
Thanks,

Hi Samosa,
Thank you for your post, I am sorry to hear you are having a similar issue.
Can you please give us some more info on what is going on? Is the issue exactly the same?
I have checked our systems and can see you have not rebooted in 11days, could you do a reboot to see if this helps?
How is it all looking? Keep us posted 😄

Hi Zoie,
I believe the same issue. On the router's UI it reports the connection on routers WAN port is 100mb, this is supported by various wired speed-checks which average around 87-91mb. Rebooting the Hub seems to fix the issue until it re-occurs, it was more frequent in the last couple of months however since the last reboot 11 days ago it's not re-occurred yet and currently routers UI is reporting the WAN connection at 1gb.
Just for kicks, I've rebooted the hub again.

Hi
Im having the same issue 1gig service but its up and down terribly often around 100Mbps. Ive rebooted the hub 4 in modem mode multiple times and even changed router. Still very unstable, its been like this since Friday 10th June 2022. Is there anything you can do to help please?

Hi andrewglass3,
Thanks for posting, and sorry to hear you've been getting some slow speeds.
Looking at things from our side, everything looks to be within the specifications we would expect.
Can you confirm if you're testing on both a wired and wireless connection?
