3G Dongle not connecting

[alan_smithee]

I've a RT AC66U with Firmware:3.0.0.4.374.38_2 (Merlin Build). I recently bought the Huawei E3131 (Which should be supported)
http://event.asus.com/2009/networks/3gsupport/

The problem is that the router won't connect to the 3g network.
In the Network Map it show "HUAWEI HiLink" so I think i finds the 3G dongle.
The dongle led stays clear blue what indicates it is connected to a 3g network.
The dongle works on my laptop without running a setup.

These are the settings on the router usb setup:

Enable USB Modem: Yes
APN service(optional): office.vodafone.com
ISP: Vodafone (also tried manual)
Dial Number: *99#
PIN code: (disabled the pin on the sim)
Username: vodafone
Password: vodafone
USB Adapter: Auto

I don't know what to look for in the log.
Any help is welcome.

There's been a lot of change to the USB code by Asus in recent versions. Try upgrading to 374.39, which has a more complete implementation of their recent USB Hub code.

Thank you for the fast response.
I've update the firmware last night and I notice the changes in the USB configuration.
I don't have to manually input the USB settings because the preconfigured setttings (netherlands - Vodafone) are good.
But in the network map it still says "Secondary WAN: Disconnected"

I've been searching in the log but I can't find anything that tells me why it won't connect.

This is what I could find in the log after a reboot.

Does anyone have any experience with the Huawei E3131 or with Vodafone (Office.vodafone.com) ?

One thing I noticed is that when I put the dongle in my laptop it has an 192.168.1.1 adres that it automatically goes to.
On that page you can view the connection status etc.

Maybe that interferes with the router ip adres?

I've have the latest firmware on the dongle.

When I run an ifconfig on the console I can't see the 3g modem

 

[plun]

You have a HiLink modem and this sort of modem doesn't need any drivers (built in)

First you need to enable auto-connect with the modem connected to a PC, go to http://192.168.1.1


Then just enable "dual wan" in the router, plug in the modem and reboot and the rooter itself should recognize that the modem uses 192.168.1.1 and give the router another LAN adress.

 

[alan_smithee]

Thank you all for the help
The problem was indeed that the dongle takes the 192.168.1.1 gateway
Even though the router was on 192.168.1.254 it did not work

So I had to move my entire netwerk (I use static IP adresses for all my devices) to another subnet.
My router is 192.168.2.1 and the dongle is connected to 3g

Once again thanx for all the help

 

[alan_smithee]

I noticed that the connection switched from connected to standby a couple of times even though the primary wan connection was still disconnected and the internet traffic was really slow.

The reason: My cable provider changed the IP adres of the monitoring webpage on the modems to 192.168.1.1 and the Asus router has an IP conflict with the dongle.

I can't find a way to change to default gateway of the Huawei dongle (not documented) nor can I adjust the ip adres of the modem.

So I see only one option put a extra router between the modem and Asus router.

Did you plug that stick into your PC and setup the Huawei software thats normally stored on them? Its how you configure them.

 

[alan_smithee]

When I use the dongle on my pc it's starts up a webpage and configures an adapter automatically. No input or driver install is required from my end.
The settings that I can adjust on the webpage are really limited.
Provider, auto connect etc.

In the adapter settings (throught manage devices) there is an option to adjust the gateway value but that doesn't work. I changed it to 192.168.3.1 but the dongle keeps pushing a 192.168.1.1 gateway with 192.168.1.100 as an client ip (even after reinserting and renewing the DCHP).

I've read on a couple forums that you can run the dongle in debug mode or change it to a dail in modem.
http://tjworld.net/wiki/Huawei/E3131UsbHspa

But I don't want to brick my brand new dongle. So no luck there.

 

[r00t4rd3d]

What happens when you plug the dongle into your pc and you goto 192.168.1.1 or what ever the dongle's ip is?

 

[alan_smithee]

It brings me to a status/setup page with very basic setup options.
Settings only shows: autoconnect, roaming, reconnect etc.

When I unplug my modem and just leave my router and dongle running I can also acces that page. Only when I reconnect my modem (without the cable signal) it brings me to e modem page since that also has the 192.168.1.1 webpage

second router did not work still the same problems.
After a third look in the log I find this line

So I turned off STP and now everything is working fine.
