Hi all,

A newbie on the forum and seeking some assistance from far more technical savvy individuals 😀

My Hub3 wasn't performing that well so I purchased a D-link AX1500.  Set up went well (I thought), Hub3 into modem mode, connected it to the D-link.  I've a mix of ethernet wired through the house and these devices are working very well.  Phones etc are running well via wifi but I have two chromebooks the kids use that are constantly losing connection with No Internet, secured.

D-link App on mobile shows a speed test of 213.4 download/20.7 upload.  

Any suggestions?  Thanks in advance.

Is the firmware up to date?

Do you have a SSID for 2.4 and 5 bands?

Try the chromebooks on 2.4GHz

Yes, I've checked the firmware on the D-link and it is up to date, similar for the devices.

No, I haven't changed anything so it will be 2.4/5 on the same settings.

I've logged into the H3 via 192.168.100.1 and it is showing:  Wireless (off), Internet (modem only) so it looks like the Modem only setting is working okay.   

Under the network status link, under the network log it is showing two critical priority and two warnings in the last 2 hours.  Warnings are RCS Partial Service, critical are SYNC Timing Synchronization failure.   

Not sure if any of this helps identify the problem though!

Long shot... did you connect it using the "correct sequence" as per belpw? If not it would be worth a try
_____________________

Disconnect all cables from your new router (or Mesh first unit) and unplug it. Put the VM Hub into modem mode (see VM website for “how to” details) 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, set up your own router/Mesh with the WAN port set to be in DHCP & Nat mode, it may be pre-set that way anyway. Make sure it’s fully initialised (leave 5 min) and then put in the WAN cable to the VM hub. Now power up the VM hub and you should get a connection. Use the recommended App to connect 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.

On your D-link AX1500 can you give 2.4G its own SSID and 5G its own SSID.

I don't think this is the issue as this would affect all connected devices.  As stated earlier split the SSID into two distinct names, e.g. append _2 and _5 to the names.  .  This will allow you to connect to a specific band and may stop the Chromebooks disconnecting.

Post your power levels and Network logs for comment to see if we can spot the issue around the SYNC errors.

FWIW, I had the exact same issue when I was using the D-Link Router.

It also had the worse App I have ever used for a router or Mesh system.

I changed to an Asus AX56 and the difference was incredible

Yes, I've now given the two channels their own name.  I've tried connecting a Firestick as a test and I can see both channels but the wifi is so weak that I can't get connected.  The Hub3 was okay.
