I'm happy with 3.7.1 from a reliability perspective.

I've got 8 routers deployed on it now for testing, no crashes, good
performance, I'm happy.

Still need some features to land in iptables and gui work, and dnsmasq
to get out of beta and I'd like to finish up simple_qos to become
ceroshaper...

etc...

but go for it!

In this case nfq_codel is on ALL 4 wifi queues, so you will need to
parse those. Also the debloat script modifies the size of those queues
significantly vs a vs a default openwrt setup.

Also I disable ecn on at least one queue...

Well, I'm a command line guy, but you can do all this via the gui if
you do it all in one go. However:

In /etc/config/firewall:

Change the ge00 entry to the wifi device you are going to use - this
will turn on nat for that device.

Replace the wifi interface with ge00 on the other entries in the firewall.

In /etc/quagga/babeld.conf for the wifi device you are going to use.
Enable it for ge00 if you are going to use that for something.

Assuming you are using dhcp on your wifi...

in /etc/config/network

...Basically swap the ge00 and wifi entries...

in /etc/config/wireless

Enable "sta" mode for the wifi interface you are going to use. (mildly
easier to get this right via the gui)

in /etc/config/dhcp

disable dhcp service on the wifi interface you are going to use

cross fingers, make a small blood sacrifice to Murphy, reboot.

I note that both vi and zile (emacs) are installed from a command line
perspective.

...

As for the usb approach, I think usb-net is built, but have not tried
it recently. There used to be support for several 3g usb-modems, in
fact, installable via opkg.
