Wifi goes down frequently - DHCP renew, No response T3 and ATOM self healing

[Noobify]

Hi Experts,

I'm on Hub 3. Experiencing terrible wifi stability which disappears almost twice a day and comes back up once restarted The technician who visited couldn't resolve with usual cable check, replace with another Hub 3 splitter check etc. Here are the logs: - any solutions or advice ?

Your BQM is fine I suggest you look at getting your own wifi router with 1Gb ports and use hub in modem mode

There is a hardware fault with the HUB, so putting it in modem mode probably won't resolve the issue.

The second technician came today and changed the upstream power levels, said the Hub is fine. Fingers crossed, let's see. In any case planning to use the modem mode in future

"ATOM is restarted" continues, it must be the processor in the Hub. Third technician booked, then I can get freedom from this amazingly reliable service !

Hi @Noobify 👋.

Thanks for reaching out to us. Apologies for the issues that you have had with your hub, I can see you have stated you will be having another engineer, and have spoken about modem mode, could you please on the day that you have the engineer, should you get a replacement Hub, do not switch into modem mode straight away. We would need the Hub to complete its initial set up as well as any and all updates as it has been in storage since we have released updates. This would need to be in router mode for 24 hours to allow for it to be at maximum performance,

Moved to a Mesh with Hub 3 in modem mode, the stability has improved but issue still exists, here are the network log again, in case any one can find a cause, may be @Sabrina_B ?

The upstream power is fine, actually.  The power level from Hub is commanded by the VM end and is contingent on whether or not the VM end can read the keep-alive messages from the Hub.  In modem mode, the ATOM messages are unlikely to occur because the (wretched) Hub 3 has nothing to do other than act as a bridge to your router.

The DHCP Renew messages are passive and you don’t need to worry about them.

So, in terms of your experience, what is going wrong now?

Thanks so much !
