IP lease time optimising network performance

General question. In case of having a large number of devices. Let’s say 100 of which a 30 have a static IP on a single network. What would be the best approach in term of IP management. I currently have a lease of 48hrs.

I try to find the optimal settings for my router to give the most stable net work. I experience loss of connection with a reconnection within seconds to 1-2 minutes if it happens. I try to resolve that by managing a separate range for dynamic (DHCP) and static ip address and lease time.

Any advice?

I use static IPs for all devices that are serving data. That means everything from ESP32s to servers. For devices that do not serve data (like my phone) I use DHCP.

That said, devices should not disconnect for up to 2 minutes when their lease expires. What router is this?

Most stable but most work: static IPs for everything except mobile phones and laptops.

I use a Teltonika RUTX50 bridging to TPlink Powerlink network. The WiFi signal is strong everywhere but nevertheless I see devices disconnecting and I can’t see why. And some times it takes too long to reconnect.

Hence the discussion about static/dynamic and lease time.

Is that a mains power line link?

They are all notoriously unreliable.

Yes it is. Giving the distances it was the only manageable solution. I noticed that this loss of connection started to increase with increasing numbers of devices. I used to be very very stable. Now I have for some devices a rock stable connection on a single extender in combination devices which tend to drop.
