I have about 62 devices hanging off 4 Unifi APs (A long house with a double brick wall down the centre).

There a mix of WiFi controlled heat pumps (they are my canaries! They start reporting connectivity errors and refuse to operate when things are about to take a turn for the worse.) The rest are IOT lights and switches, a few rings cameras, 3 smart TVs, and of course a couple of laptops and mobiles. And we often have guests around using our network too.

Whilst I might be ahead of the curve for a typical household, this is the way things are heading, and ISPs should IMHO be able to cope with it.

62 devices seems high, but not unduly so, especially given IoT devices shouldn't have a whole heap of concurrent outside connections open.

On the Unify, can you log in to the cli and see how many nat connections you have? I know little about Unify but I would expect this should be possible.

Biglegs:

Unsurprisingly this seems to have worked, the connection is solid as a rock. The question for me now is if CGNAT doesn't deliver for all its customers, should I have to pay for an IP address to fix it? I have no desire to expose internal services to the wider internet and would be quite happy with a CGNAT solution - sol long as it worked reliably. Apparently it doesn't.

The problem is that CGNAT probably does deliver for the vast majority of their customers. As an outlier it's probably easier for both you and them if you either pay for a static IP or move to a provider where it's included (one-off fee).

Hi many ISPs provide public IPs that are not static but will change from time to time, regardless those connections will not be impacted by Nat overload overload issues that a cgnat connection can be as discussed here and they are not charged for as they are not static.

CGNAT might be a red herring given @nztim is seeing the same issue and has a public IPv4.

Here's a final update on this issue for those that are interested or may discover this thread.

Since switching to a static IP, the router has been up without a single hiccup for 4 weeks and 1 day. I contacted tech support at the end of the month as requested, and they agreed that it was highly likely that CGNAT was not coping with the high number of device connections. They could not offer classic DHCP, so static was the only option to guarantee a stable connection. I pointed out I had no need for a static IP, only a stable connection. I also pointed out that whilst I might be an outlier at this point in time, it may certainly become the norm in the near future so they would eventually need to adapt.

After a conversation with their escalation team, it was agreed to continue the free static IP for 12 months, after which we'd review again. I will seriously do that. Who knows - there may be changes to CGNAT by then.

2degrees need a public dynamic ip option

Sky broadband is the same price and uses the 2degrees network

I am with Sky, who re-sell 2degress, same deal, but 2degress don't offer public dynamic direct to their own residential customers
