I am indeed running them on Ethernet. I don't actually use the B818 for 
anything else than as a LTE modem, so I wouldn't know, if I could get the thing 
to bridge I would. Or replace it with something else entirely that I can 
control, but that doesn't seem to be an option on FWA. That said the Zyxel 
looks like a better option since I assume it acts like a bridge by default.
The Zyxel device indeed acts as a bridge, or at least as close approximation as 
we can get it.  The PDP addressing protocol in mobile networks requres the 
address termination to happen where the SIM card resides.  So the device does 
some trickery with brctl, routing and iptables to simulate a bridge setup.


I dumped the raw signal stats the web interface grabs in an XML file together 
with the Flent tests. Also did some upload only tests tonight at different 
speeds (no VPN in play this time).
rsrp is good and rsrq is great at your location.  However you have ended up on 
the 800MHz band.  That is intended for coverage, not capacity.  It uses only 
10MHz bandwitdh and is shared with a lot more customers.  You probably should 
be able to get an 1800MHz frequency which has 20MHz and is shared among fewer 
customers.

Most likely yes. That's been my observation as well, that it generally acts up 
the worst when somethings using the upstream. Not entirely sure what I can do 
about that, seeing as I had to shape at 5Mbit to get rid of the worst spikes 
(but not all).

This is tricky.  You don't have a static set of resources.  You request 
resources "as needed".  The "as needed" amongst other things reads the buffer 
back pressure.  So if you shape to far down the LTE device will not request 
enough resources.  Shape to high and there will not be enough resources 
available to share.  And available resources vary with number of subscribers on 
that cell, weather, the subscribers usage and interference from other cell 
towers.  To get a proper solution to this I don't see a way around getting the 
chipset manufacturers on board.



On that point, I would've liked to collect signal stats over time, but the B818 
seems to insist on chucking me out after being idle for a few minutes, better 
known as scraping the stats with cURL


Have you tried to use the telnet service port (20249) on the B818?  Not all 
variants have that open but you could give it a shot.  You also may need to 
acquire an datalock code for the "at^datalock=" command.

telnet LAN_IP 20249



This is getting LTE/5G spesific.  Not sure if it belongs on the list.  Let us 
know if we are generating noise.
