HUB 4 to Zenwifi Pro XT12

[BruceT]

Hi 

I want to connect a ASUS Zenwifi pro XT12 WiFi mesh system to my HUB 4 any recommendations best way to do this

any recommendations what mode to run the ASUS Router in

i take it I put HUB 4 in modem mode and connect wan port from ASUS to port 1 on HUB 4

any advice would be most appreciated please

wifi on HUB 4 very unstable so need the XT12 to boost signal and provide AX features for multiple devices and gamers in the house

thanks

any recommendations what mode to run the ASUS Router in

If you're running the hub in modem mode, then you have to run the Asus in router mode.  If you run the hub in router mode, Asus has to be in access point mode (I think Asus may use the term bridge mode, means the same thing).

Our general view is that there's no point running a VM hub in router mode with any competent mesh or third party router, because the hub's router will be inferior, although it will work if you need to run things that way.

And connect it in this sequence.....
____________________________

Switch on and set up your own router/Mesh unit (in its settings) with the WAN port set to be in Automatic IP i.e. DHCP (& Nat) mode, it may be pre-set that way anyway. Then, disconnect all cables from your new router (or Mesh first unit) and switch it off and unplug it. Then, put the VM Hub into modem mode
( https://www.virginmedia.com/help/virgin-media-hub-modem-mode )

and wait for the base light to turn magenta/purple (on a Hub3 - but not on a Hub4!). Once it’s in modem mode, the VM hub “MUST” then be powered off.

Then switch your router on and make sure it’s fully initialised (leave 5 min) and then put in the ethernet cable from its WAN port to the VM hub (any port will do).

NOW… power up the VM hub and wait 5-10 minutes for The Hub to initialise and and you should get a connection. Use the recommended App to connect any other Mesh units to the first one. This order only needs to be done the first time you connect the router to the VM hub.

Thanks gents setup went like a breeze and worked well and first time.

pity my hub 4 is still unstable and network needs to reconnect every now and then during the day. At least I now have world class ax based mesh network in my place and it’s is super quick when I have VM signal.

That's good.

Now let's see what we can do about the unreliable broadband:  Pull up the log in page for the hub.  But don't log in, just click on the link "Check router status"  That'll bring up a window with five tabs.  Open the Downstream tab.  Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here as TEXT not screenshots.  Post that, do the same for the Upstream and Network log.  You'll get an error message when you post the Network log, just click on "post" a second time.  Then we can check for any obvious problems with power, noise or error counts.

@Andrew_G the upstream has no errors now as this was a post-reboot of Hub I had to do this AM. I took photos of the logs and  status, what I saw was T3 timeout of Chan 1 =-31 2=284 3=285 4 = 309 all channels 64QAM modulation

The  Hub is having to reset the connection due to up and downstream errors upwards of every 30 to 60 mins during the day. VM Technical have replaced the hub beginning of the week thinking it may be the hub after a line test was very successful but I'm starting to think it is not the hub. I have a new line pulled into the cabinet in late Jan so the last mile is brand new and the installation was brand new.  

For some reason, I do get some stability in the afternoon  but then at around 7 pm the Hub starts to reset the broadband connection, when I look at the stats the errors happening on T3 timeouts is  fairly big as per above in some cases  as well as downstream pre and post rs errors

The HUb is running in Modem mode
