It looks like this is the manual here
https://consumer.huawei.com/eg-en/support/smart-home/b311s-220/
two relevant takeouts for me were,
- There appears to be a wifi mesh type product that accompanies it - HiLink
devices? using your own mesh setup may interfere with its built in
ways...
- It looks like you can disable its inbuilt WiFi, DHCP NAT etc and use it
in "pass through" mode. This is how you would want you to use it in
conjuction with a real router and your own existing Wifi equipment, it
would reduce that box to modem mode.
from Scenario Constraints..
A maximum of 32 devices can be connected to the WLAN in theory; the actual
number of devices that can be connected and served depends on actual
conditions.
nice and vague :-)
I wouldn't use it by itself as a small business router, i worry about how
long it will hold out in full daily use without needing reboots. But
attached to something like a draytek in WAN2 to be a mobile broadband
backup line it looks pretty good especially for the price
