Internet speed slows down
Hi all,
I'm having problems with my internet speed, I'm on M500 but each day the speed drops to about 5 and I have to reboot the super hub 4. This sorts the problem, but anybody know why or how to fix.
Thanks 👍
Forum Discussion
Repeat reboots of VM Hub as you can see is not fixing anything.
1) Does a call to 0800 561 0061 reveal a VM service fault in your street ?
2) Do the Upstream / Downstream Hub status tabs show and signal levels issues or many and increasing errors ?
3) Use the link below to see if there is a Speed to VM Hub issue, or a VM Hub to device issue.https://www.samknows.com/realspeed/
Once the test begins click on: Run full test to see all the stats.
The speed at the Hub should reflect your subscription.
The speed any WiFi device draws data at is limited by its data needs and technical abilities.Thanks Client62,
1) no problems in my street
2) I have the hub 4 in modem mode and cannot access 192.168.100.1 for some reason
3) realspeed says not available on this network.
I'm using archer 20 router, tried this thinking it might help with the problem, but still the same issue
Apologies the router I am using is the TP-Link AX1800
Same again today, speed down to around 5mb restarted router and back to over 500.
Hi tonytheblue
Thank you for your post. I'm sorry to hear you've been having some trouble with your broadband speeds. To clarify, is it your download speeds you're having trouble with?
I've had a look at your specs and everything does appear to be normal. Your downstream channels are slightly on the low side, but only just and shouldn't really be causing any problems. Your BQM also looks great - no signs of issue from there.
You mentioned you're struggling to access 192.168.001.1, is it the Hub page you're trying to access? If so, please note that it is 192.168.0.1 😊
What sorts of speeds are you receiving over a wired and wireless connection?
2) I have the hub 4 in modem mode and cannot access 192.168.100.1 for some reason
It doesn't hurt to read the OP's messages!

Your levels are perfectly good EXCEPT the all important DOCSIS 3.1 channel which has reduced SNR and really low power that should raise more than an eyebrow. This is where your problem lies, assuming that your WiFi environment isn’t suspect.
Thanks, is this something I can rectify or will it require an engineer?
Morning tonytheblue,
I've had a look at things from our side, and it's identified a performance issue that requires an engineer visit. So I can arrange this I've popped you over a private message.
Alex_Rm
Despite what the Forum Team have told you, the level is unacceptable, especially as you have reported problems. It requires an engineer who knows how to resolve a DOCSIS 3.1 issue - and will also need to have access to 2nd line support, imo.
@tonytheblue
I urge you to ensure that the technician sees your stats and in particular the DOCSIS 3.1 downstream. The technician has the portable measurement tool necessary to confirm all this and the noise associated with the poor power levels.
What we haven't heard from you is whether or not you have checked that your coax cables are tightly screwed in. This check is very strong advice.
Please let us know.
Just an update, tech visited Friday and after having a look at the setup and the cabinet has arranged for re-wire on Wednesday.
He said the same about the docsis 3.1 levels being wrong.
Thanks
Thank you for updating us tonytheblue please do let us know how things are looking after the work on Wednesday?
Thanks again
And yet the BQM looks great. No dropouts, no reboots.
