Hi,

I have recently switched to VM, been looking at Think Broardband Quality Monitor, please can someone explain the following.

Why does using the asus dynamic name to find my connection vs using the current IP give different results?  I would have thought once the monitor finds the IP it would then test the current IP?

Via Asus Name

direct current IP address

I have had these not so good looking results for some time with previous FTTC provider, is it just due to the number of devices on my network causing traffic or is their something I can do to improve. (My mums Sky connection just has a green bar sitting at 10ms)

Regards,

Steve.

Yep, it's a bad connection.  Looks like the upstream power's too low, and I've marked that for the staff to take a look.  If they agree (or can see other faults) they'll book a technician for you.  This has nothing to do with the number of devices on your network, it is a fault between the hub and VM's network.  Other than a reboot, possibly a pinhole reset, and checking that the coax cable connections are finger tight there's nothing you can do.  If you're using a third party router, I assume you are operating the hub in modem mode, or have the third party router in access point mode?  Having two routers active in DHCP router mode on the same network could also cause those sorts of poor BQM results. 

There will always be a small yellow fringe on a cable internet connection, because the technology isn't as consistent as that used by Openreach, but it shouldn't normally be enough to be noticeable in daily use.  This is a good day for my connection, and about what you should expect:

Hi @iamSteve,

Welcome to our community forums and thank you for your first posts.

Thank you for flagging your Think Broadband Quality Monitor to us. We can understand your concern and want to best help. As mentioned by @Andrew-G , there seems to be an issue with your service connection. I have sent you a private message regarding this. Please look out for the purple envelope and provide a response when you can.

Thanks,

[iamSteve]

Please can someone further explain this to me?

So today at 2pm I disconnected my Asus Router from the Hub 3 and Factory 'pin' reset the hub, and allowed it to connect back up as a Virgin Hub 3 router, this was the quality graph with a new IP address.  Other than removing the Cat6 to my Router Wan no other cables were touched.

Then after this I changed back to Modem mode and reconnected my Asus router.

Clearly there is a big difference between the hub in 'router' mode with one device vs 'modem' mode and my Asus router and network connected.

Why is this such a difference?

Why did the IP address change back to the same one when set as modem?

(To clarify my question above, I understand the IP changed when I reset, and a new one was picked up but when I switched back why was a new one not obtained OR the recent one remain, why did I get my old one back?)

Hi iamSteve,

Sorry I had to reject your images showing the majority of your IP address. It's against Forum rules.

VM IP addresses will change if you use a 3rd party router, however connecting directly to your VM hub you will retain the usual IP address.

Although VM IP addresses  are not static (unless you have business broadband) they are to all intent and purpose practically static and generally only change if VM send you a new router, or in some instances when VM have performed to major external work/upgrades.
