I’ve had this issue for the last 3 years or so where at completely random times, the wifi drops and can’t connect to internet. Only a restart of the router will fix it.
Was previously with orcon and they couldn’t fix the issue they tried sending us new router but issue still persisted.

back in march switched to sky broadband and it was fine for the first couple months but it’s started again. Almost daily at this point. Once again restarting the router fixes the issue- until it happens again.

any ideas?

Deploy your own wiresless solution and disable the wifi on your toy router, lots of great choice out there. Grandstream, Ubiquiti, Mikrotik, Alta Labs.

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

Have removed the isp router and using google wifi nests as mesh network. They have been replaced to see if that resolved it but issue still persist.

So does this only affect Wireless clients? Do you have any wired clients?

Despite changing from Orcon to Sky Broadband your underlaying ISP still remains the same (2degrees).

Kinda sounding like CG-NAT port exhaustion to me.

How many clients would a CGNAT ISP be putting behind a single IP address to be able to exhaust so many ports?

You’d be surprised on how easy it is. Shoppify can do it by itself.

Use a UPS, I would say you have dirty power.

You need to be clear exactly what you are talking about. You said the wifi drops which literally means the client device disconnects from the wifi. If so one would assume that the SSID is no longer visible. Is this true. Obviously if there is still a wireless connection between client and router then you don't have a wifi issue.

Just saying "Wi-Fi drops" makes it harder to diagnose and ISPs don't always have the best support.

To summarise the above:

Is this affecting Wi-Fi only, or can you see wired devices also lose connection at that time (indicating either a router issue, or ISP issue).
The fact you are using a different router but still seeing this problem seems to indicate this is not a "Wi-Fi drops" problem. In this case, as suggested, have you tried a filter or UPS to make sure there's no power problem?
Have you tried a different ethernet cable from the ONT to the router?
What are the ONT lights showing when "Wi-Fi drops"? Could be a ONT problem?
Are there other devices on your network at that time? Is QoS enabled? Could another device be infected with some malware and using all the bandwidth available?

Think about these, test well and document these details. This will make it easier to decide if this is an ISP problem or a hardware problem (ONT/router/cable) on your side (although I think router would not be the problem seeing there is a new one in use).

@GSMainic had a thread about this exact same issue in 2022 and they were advised to bin the GWifi.
