Cable internet to 4G internet conversion

I have SUSE 11.0 set up to act as a router/firewall for my home network to the internet through a cable modem attached to an Ethernet card. When I was laid off several years back, I found information that let me connect my network to an ISP via a standard serial modem. I am considering going to the Sprint U1901 4G USB modem and dropping cable internet. Sprint claims the U1901 is Linux compatible. My thoughts are that using the 4G modem should be similar to the old dialup modem. I had a script that connected to the internet whenever internet traffic was detected. Unfortunately, I did not save notes on what I had done to setup the modem to dial automatically, and I have been unable to locate information that seems good to set this up again. I already know that all I had to do to get routing working was simply replace the internet port in the firewall/routing script with the port for the modem. So I assume that is rather trivial.

Would you please point me to a doc, perhaps SuSE specific, that gives reasonable directions on how to set up a “dial on demand” ISP connection? I assume that the 4G modem will be very similar to my old serial modem so that a dial on demand script will work. I did find a dial on demand howto, however, it did not seem to apply.

Also, any information on connecting a USB modem would be helpful, too.

Thanks in advance.

Some time ago I posted info on setting up a mc950d usb modem under Linux 11.1, & 11.2. I no longer have this modem as costs ballooned way too high ($50/month plan shot up to $250/month when exceeding 1GB). If you search either my posts or the mc950d you should be able to see that such modems are seen by knetworkmanager and Yast as Wifi USB devices and the dialing if I remembered right is handled by the sim card.

My isp provider was rogers so YMMV. Good luck

Further to my last post, be aware that sprints 250u modem connects to 2g, 3g, 4g networks but not 4g wimax. the U1901 modem connects only to the 4g wimax network AND not all areas are covered in the wimax network. If you fall outside of the wimax area you will have zero connectivity due to it not being able to connect to non-wimax systems. Sprints coverage under wimax are very vague with a lot of if’s, possibly’s, and maybe’s.

Thanks for your replies, and for the tips about where service might be available. I’ll search for your posts.
