Minimum pakages to get USB Modem working

[colinkhalid]

I have a TP-LINK MR 3420 router.

Is there enough space to get USB Modem packages installed on this router and which one should I install ?

this is the output from the free command:

Shane has made this documentation:

I think that he will also reply, as he has experience.

thanks

I did manage to get the following packages installed:

kmod-usb-core
kmod-usb-serial
comgt
chat

but failed to install kmod-usb-ohci and kmod-usb-uhci because there was not enough free memory.

The modem a Huawei E 1752 could not be found.

would be grateful for any suggestions

comgt kmod-usb-serial kmod-usb-ohci usb-modeswitch usb-modeswitch-data

Did it for me

Ok that good news, you are using a TP-Link 3420 ?

No! I'm actually using a 841ND v5 with usb modification...
But it's working great with TP-LINK MR 3420 Image and the packages i recommended...

Hardware seems to be the same regarding Ram and Flash memory...

EDIT:
I forgot to mention that i have only tried this with Huawei modems.
Working with all my modems: E1550, E180, E173, E220.
Hotswapping them is also working flawless
You should also edit /www/data/apn.csv for convenience.
I also had to add: option 'pppd_options' 'debug noipdefault'
to /etc/config/network.

You should start with a clean fresh router and install:
opkg update
opkg install comgt kmod-usb-serial kmod-usb-ohci usb-modeswitch usb-modeswitch-data

sync
reboot

Good Luck!

Regards.
