Huawei E169

[PlanB]

Does anybody know how to adapt viewtopic.php?f=36&t=18996&p=806992#p806992 to work with a Huawei E169/620/800 which loads as 12d1:1001 across ttyUSB0-ttyUSB2?

Thnx for the links but I've tried then already. Sakis terminates early when it gets an error response to a pin request & wvdial connects OK but hangs after the 2nd ary DNS is issued. I was hoping I could maybe get somewhere with Huawei's HiLink.

If you have a RPi B+ or later, you could increase the USB BUS from 600ma to 1200ma if you have a decent 5V2A PSU

Nah not a power supply problem, I've jigged it so the red power light doesn't flicker. Just out of my depth I think, heaps harder than WiFi. Mr. Engman you need to bring your deft hand to this me thinks!

Is the device being set to a USB Mass Storage Device ?

It's in modem mode, the problem seems to be the default route. Normally pppd would end with something like

Code: Select all

--> secondary DNS address 85.237.225.250
--> pppd: [10]gv[01]
--> pppd: [10]gv[01]
--> Script /etc/ppp/ip-up run successful
--> Default route Ok.

Mine ends with

Code: Select all

not replacing existing default route via 10.0.0.138
local  IP address 10.168.205.247
remote IP address 10.64.64.64
primary   DNS address 10.4.81.103
secondary DNS address 10.4.182.20
Script /etc/ppp/ip-up started (pid 3040)
Script /etc/ppp/ip-up finished (pid 3040), status = 0x0

The existing default route is my wifi router but i can't figure out why it still wants to use that because I've modified /etc/network/interfaces for the 3g dongle

Code: Select all

iface ppp0 inet wvdial
allow hotplug wwan0
iface wwan0 inet dhcp
