I have now been able to try out the ZTE MU5001 in concrete terms (the advanced settings are only available on the desktop browser or PC WebGUI, the mobile browser WebGUI is rather very reduced):

- There are 3 WiFi SSID available, 1*2.4GHz and 1*5GHZ as well as 1*2.4GHZ guest access. For all 3 SSID, SSID name, password and SSID hide can be set separately (optional). For Wifi guest access, the device connected to it can optionally be automatically isolated from the other WiFi SSIDs via the firewall.

- The internal IP network and the network range of the router can also be set as desired. The same applies to the associated DHCP range (IP4 and IP6). However, all 3 SSIDs share the same internal IP network (there is no possibility to define a separate IP network for the Wifi guest access).

- There is no flight mode (as e.g. with Netgear AC810S).

- The WebGUI in both desktop and mobile browser mode is "somewhat" unstructured (compared to the Netgear AC810S).

- USB-C and Ethernet ports are without covers to protect against dust and lint deposits.

Conclusion I can actually recommend the device. I cannot say what the device is capable of in terms of 5G, as this is problematic in the Italian networks (where I have now tested the device), as the feed lines to the 4G/5G antennas are very often overloaded from my own experience (max. 4G/5G signal but hardly any real data bandwidth - often over lunchtime and in the evening).

Unfortunately, I can't help with the guest access and the SSID because I use the router alone. On my 2nd router FRITZ!Box 6850 LTE 5G it works. With kind regards
