3g does not work on 1.5.8

[sonykphilip]

The changelog for 1.5.8 says 3G fixes, but I there is no menu option for 3G wan.

Ive tried 2 usb 3G dongles (both by Huawei), usb_modewswitch has entries for both, but there is no /dev/ttyUSB0.

BTW, its a WZR-HP-G300NH. I moved over from DD-WRT v24sp2-r18777 where I was using the same dongles successfully.

Well this didnt get fixed in 1.5.9 either, but I managed to get it working myself.

If you

Code: Select all

cat /proc/bus/usb/devices

and you find that modeswitch has successfully switched to the target Vendor/Product ID eg,

Code: Select all

Vendor=12d1 ProdID=140b

because I already had

Code: Select all

cat /etc/usb_modeswitch.d/12d1\:1446
# Huawei, newer modems

TargetVendor=  0x12d1
TargetProductList="1001,1406,140b,140c,1412,141b,1432,1433,1436,14ac,1506,1511"

then it COULD be because kmod-usb-serial-option and kmod-usb-serial-wwan are not installed.

Do

Code: Select all

opkg install kmod-usb-serial-option

If it refuses to install try

Code: Select all

opkg --force-depends install kmod-usb-serial-option

You should get:

Code: Select all

opkg list-installed | grep kmod-usb
kmod-usb-acm - 3.3.8-1
kmod-usb-core - 3.3.8-1
kmod-usb-ohci - 3.3.8-1
kmod-usb-printer - 3.3.8-1
kmod-usb-serial - 3.3.8-1
kmod-usb-serial-option - 3.3.8-1
kmod-usb-serial-wwan - 3.3.8-1
kmod-usb-storage - 3.3.8-1
kmod-usb-storage-extras - 3.3.8-1
kmod-usb2 - 3.3.8-1

.

After this, ttyUSB[0,1,2] came up for me in 1.5.9. I dont know why its been left out but Im happy it works for me. YMMV.
