I set up my home network all through this 3G wifi router. Problem is it only allows 5 devices to connect. That's not much especially if a wifi printer and gaming consoles keep hogging these slots. On the other hand I don't see the point on blocking these devices. They are (should) not doing anything online just intern in my network.
The documentation I can find is surpirisingly unhelpful and focuses how to plug the device in a power socket.
So what would be my options.
Notes: I have already been able to get a shell on the device using ssh. It's running some Busybox. But I fail to find the how and where this limit is enforced/created.
Notes 2: Specifically my device is a 3WebCube - unfortunately not specifically marked with the Huawei Model number.
Successes so far
After enabling ssh in the options I can login:
ssh -T

unfortunately because of this -T - the tab key does not work for autocomplete and all inputted commands will be echoed. Also no history with arrow keys.
ATP interface
this custom interface is not very useful:
ATP>help
help
Welcome to ATP command line tool.
If any question, please input "?" at the end of command.

Shell
BUT undocumented - I somehow found on a auto translated chinese website - all you need to do is input sh
ATP>sh
sh

using tftp
after installing tftp on my desktop I was able to send files with
tftp -s -l curcfg.xml 192.168.1.103
and to download onto the huawei with
tftp -g -r curcfg.xml 192.168.1.103
I think I'll need that - because I don't see any editor installed.
readout stuff
(still playing around where I would get interesting info)
