[SOLVED] Can't Access Wired Connection

Decided to upgrade my internet access from a 3G modem to a 4G hotspot. I've got a T-Mobile Z64 (ZTE MF64). It works great with Win7, which is how I'm online right now. I can't seem to get it to work properly under Linux (Slack64 v14.1), however.

What I've already read says that it shows up as an ethernet connection, instead of a modem, which it does (eth1). I can bring it up and down, and assign address and netmask, using ifconfig. Bringing it up and down shows up in gkrellm (which doesn't happen with eth0). It shows up when I look at hardware info. I've checked to see whether or not usb_modeswitch is changing it correctly, and it appears to be doing it (changes from 19D2:1225 to 19D2:1405).

The problem is that nothing I do makes it show up in Network Manager, or under networking in system settings. I've been googling and trying this, that, and the other, for a couple of days now. I only know enough to be dangerous, and I've exhausted what little I know. I just can't get it to work.

Any help is greatly appreciated.

It looks like that is not yet a known to work device.

If interested you can try to create a udev rule to swap it or flip it yourself


move somewhere safe any files in /etc/udev/rules.d that appear to be a usb mode switch
ditto any files in */lib/udev

as we don't want any interference

if you do so....remove the usb-modeswitch data package so you eliminate it from flipping and failing for you

then suggest you read this post and modify it to suit your model

make other adjustements as you see fit....below is just to give you the idea if you wish to try it


so where it says /etc/usb_modeswitch.d called 19d2:0166 , the same as the ID from lsusb

You change 0166 to 1225

now use the message content from another MF device from the text link such as
what have you got to lose?

not sure but I don't have your device so good luck

Okay, I got it working, but not how I thought I would. It seems I was overthinking things and looking for problems in the wrong places. Apparently, /etc/rc.d/rc.networkmanager wasn't set as executable. I fixed that, started Network Manager, plugged in my hotspot, and watched as Network Manager automagically did its thing. I am now, happily, online from the Linux side of my system!

The T-Mobile Z64 (ZTE MF64) works for me under Slack64 v14.1. Your mileage may vary...

Thank you, aus9, for your input/suggestions.
