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 ip= tables and gui work, and dnsmasq
to get out of beta and I'd like to fi= nish up simple_qos to become
ceroshaper...

etc...

but go for it!

In this ca= se 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
significant= ly vs a vs a default openwrt setup.

Also I disable ecn on at lea= st 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 ot= her 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 w= ifi...

in /etc/config/network

...Basically swap the g= e00 and wifi entries...

in /etc/config/wireless

Enabl= e "sta" mode for the wifi interface you are going to use. (mildly
easi= er 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 us= b-net is built, but have not tried
it recently. There used to be suppo= rt for several 3g usb-modems, in
fact, installable via opkg.
