Hi, 
This may be a duplicate of my previous post, but I can't see it so think it's just lost.

Bought an AX50 to replace the horrible routing on my Virgin Hub3.

Wired connection Hub Port 1 -> AX50 WAN port.

Configured through tether as per instructions, all seemed ok.

ookla when connected wireless through ax50 @90 whereas ookla via hub was @350 .. hmm.

Hub was still set to router mode so discounted the speed.

Changed hub3 to modem mode ... no connectivity. Amber (I think) on AX50, red on Hub (99% sure not magenta which means something else entirely apparently)
Couldnt get into Hub to look for config issues so ended up factory resetting and going back to router mode ... eventually as 192.168.0.1 was being redirected to 192.168.1.1 which was no longer online ...

Any thoughts more than wlcome

Many thanks
