My MBP works fine. Every 2nd blue moon, it gets no internet, so I renew the DHCP lease, all good. I just put that down to my old router filling up the log of DHCP connections. Lately its most mornings. Get up read the internet, get the requisite coffee then I need to renew the lease to get the Internet online.

Spark Fibre, Huawei 659B in the garage that feeds the Airport Extreme that the MBP and phones. tablets, connect to by wifi.

Any ideas? MBP is shut down most nights. When I renew the lease, it has the same internal IP

659b can only handle 32 devices from memory - would you be hitting that limit?

That rings a bell, but nowhere near that. I do recall being told the logs can fill up. Is it 32 active devices or 32 connections to less than 32 devices that come and go?

Here is my layout

659B is in the garage connected to a patch panel. We have an ethernet port in every room, only 3 are connected in the patch panel to the 659B. Wifi is turned off.

Patch Panel/659B connects to:

A downstairs ethernet port that has a cabled Airport Extreme, which is then cabled to MySky, and to an ATV4. And it provides wifi to 3 actively used iPhones, 3 actively used iPads
Other living room ethernet port is cabled to a Chinese STB
Upstairs ethernet port is cabled to my WFH laptop that VPN's to work

I could restart the 659B in the morning, leaving it off for 30 seconds and see how that goes.

I think it was 32 devices in total across wifi & ethernet but could be wrong. Would give those sort of symptoms though, with with a device just disappearing.

What model MBP & OS version?

MacBook Pro (Retina, 15-inch, Late 2013)

Big Sur 11.7.7

The odd thing is its just the MBP, and when I renew the lease, its the same internal IP, as if it got lost.

Is it the Huawei or the Airport providing the DHCP server?

The Huawei I assume, the Airport is in Bridge Mode, Airport Utility shows it connects to the Internet via DHCP

I have to say the Huawei 659B is not worth it, both Spark and Vodafobe used these modem and they have endless issues, wifi stops, overheats, needs reboot every 5-7 days. I suggest throw in Bin and buy another modem.

I’ve had no issues of note. I do need to power cycle it from time to time but that’s more like every couple of months or more
