Apologies if this has already been discussed, but I couldn't find any recent posting on this topic.

I have an old Telstraclear fixed cable broadband connection with a Vodafone/One NZ cable modem (Technicolor TC4400VDF), originally connected to the company supplied Vodafone Ultra hub plus router.

I have recently replaced the Ultra hub plus with a new Archer AX-55 router and connected this new router to the existing cable modem (above).

After adjusting the AX-55 config (per instructions online, mainly setting VLAN ID and MTU size (PBTech)) my connection is up and running and my router is happily providing more coverage and perhaps speed.

My issue - when I run a wifi speedtest (using Chorus test on the web or using the mobile app "Speedtest") on the 5ghz frequency the modem connection just drops out completely and a router reset is needed to restore wifi once more.

I have run a test on the 2.4ghz frequency (it got up to about 150mbps) and the connection stayed solid. But when the 5ghz band was tested it got up above about 600mbps and then abruptly cut-out.

Has anyone else experienced this or can inform why this may be happening (didn't happen previously using the old Ultrahub)?

Thanks

Sounds like to me a power brownout is occurring and crashing the router. That’ll explain why Channel 40 works a bit better as I believe it also runs at a limited power level also.

if you can, see if you’ve got another power supply you can try with the router. I believe it should be 12v with 3 amps or greater.

So after looking at the router power supply it would appear I have a 9V 0.85 Amp power supply connected up ... which I believe is the power supply from an older TP-Link router that was plugged into the powerboard ... which hadn't been swapped out for the new supply. I will blame my son, and the myriad of cables on the powerboard, but I didn't check which supply was which and they both look the same !

Thank you for all your help here - the diagnosis of brown out was spot on.

The correct supply has 12V and 1.5A. My router now passes all speed tests and has not disconnected once since.

Thanks again
