DLink DIR-620 C1 + Gargoyle

[Sieger]

Hello @ll!

First of all, thx a lot to Gargoyle (and Open-wrt) devs&contibs for working hard on this great project(s)!

Then, here is some (hi)story of me, my tasks and my h/w:

I had to replace my DIR-412 router recently (summer-time overheat),
so I've got DLink DIR-620 C1 as the replacement.

It's master-purpose for me:
3G router

Despite it has the most recent native fw now, it's really unstable running 3G with my Huawei E1550 USB-3G oldie.
(DIR-412 was really great with this, but as I said it's gone now).

I've changed fw to some modified http://code.google.com/p/wl500g
(lly и theMIROn, mod by Vampik http://vampik.ru).
I.e. this should be some modified WL500G fw.

It works, but I really need "dial on-demand" feature (which will auto-drop/restore 3G connection after it becomes idle).
This feature do present there, but isn't operational, so I still have to look for another alt. fw.

Gargoyle would be a great solution, but I really need help installing it (if it's possible at all).

HW contents of DIR-620 C1 thingie:
CPU: Broadcom BCM5358UB0 (530 MHz)
RAM: EtronTech EM6AB160TSD-5G (64 MB)
Flash: Macronix MX25L6406EM2I-12G (8 MB)

I.e. I believe Gargoyle should fit, but Gargoyle's DL section for Broadcom has a lot of fws, so I don't know which one fits my tasks
(i.e. it has to support my E1550 USB-3G donglie =))

I really hope someone would be able to help/advice/clarify on all this?

USB 3G Modems
USB 3G modem issue (insufficient power). The device does NOT deliver enough power for most USB 3G modems, which can lead to erratic behavior such as droped/failed connections. If a 3G USB modem is to be used, consider other routers with a USB port that delivers enough Amperes. (e.g. Buffalo WZR-HP-AG300H)

Compatible USB 3G modems
e.g. Huawei E1550

any chance this could also be your problem?

ispyisail, thx for the reply!

Thats an interesting point.

Well, the 3G@USB works pretty much OK in "alway-on" mode with Vampik's fw, even though 3G dongle utilizes 3-meter USB extender cable to
connect to the router (which additionally reduces the USB-sourced voltage).

I mostly lack the automatic drop/restore 3G connection capability
(to reduce em-radiation, when 3G is idle/"unused").
