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 [email protected]

[email protected]'s password:

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.

ATP>?
?
cls 
debug 
help 
save 
? 
exit 
ATP>save?
save?
Command failed.
ATP>save ?
save ?
ATP>debug ?
debug ?
display 
set 
trace

Shell

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

ATP>sh
sh


BusyBox vv1.9.1 (2011-03-27 11:59:11 CST) built-in shell (ash)

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)
