Devices lose connection regularly

I'd really appreciate a hand with debugging this.

I've found that some devices work consistently, no problem, others constantly need reconnected and get can get stuck at the "obtaining IP address" stage. Restarting the hub can help, but within a couple of days, the same device will have connection issues again.

The router is in an adjacent room, the 5Ghz and 2Ghz networks have different names, the signal strength appears good on the affected devices and the same devices did not have issues on previous networks.

Is there a way to tell why these devices can't properly connect on the router itself?

Re: Devices lose connection regularly

Upstream looks borked (too high power and 16 QAM - should be 64
Downstream some channel SNR looks too low and loads of PostRS errors!

I'd say an engineer is needed!

Re: Devices lose connection regularly

Hello Mario64

Sorry to hear this is happening 

The down stream levels are just a bit out of the range we need 

I have booked the first engineer appointment we have available
You can check and reschedule this appointment through your online account if you need to
You can also cancel it if the fault has gone 
Can you please let me know how the visit goes

Re: Devices lose connection regularly

Hi, thank you very much for arranging the enginner.

The engineer addressed a few problems on the 19th that apparently could have been causing interference. The error section of the router page has only seen two "No Ranging Response received" errors since which suggests it's improved.

Hopefully that's it sorted. Thanks for all the help.
