Hello,

two years I used a Koppel firmware, but because
some limitations (old kernel 2.4.20, some issues
with 3G modems, ftdi drivers, usb webcam drivers),
I switched to OpenWrt and then DD-WRT.

At last I am using the renewed Oleg's firmware
from http://code.google.com/p/wl500g/.
(WL500gp-1.9.2.7-d-r2624.trx; Kernel 2.4.37.11)

I like it and has some improvements.
It recognize easily 3G modems as ZTE MF637,
connects to Internet through it; also the
firmware has System Utilization (in GUI),
a nice feature.

I liked the Koppel's firmware, GUI:
---USB Connection and Backup Connection---
* Setup [enable backup connection],
* IP address [Primary, Secondary IP for ping tests],
* Time [time in minutes for ping testing cycle],
* Primary [wired, WAN], Backup [radio, GPRS/EDGE/UMTS],
mean: if the primary connection failed, the backup
connection takes over.

I have a question: does someone are using this renewed
Oleg's firmware and has a script that switch automatically
the connections in case of failure (and switch back to
wired connection when it's available again) ?
I've noticed that with this version (in GUI)
I can only manually switch the connections
[IP Config - WAN & LAN: Automatic IP, Static IP,
PPPoE, PPPTP, L2TP, BigPond, WiMAX, USB Modem]
and has no special page in the tree e.g. backup connection.

That's all, thank you for any ideas.
