Thought you may be interested in a little project that was spawned in a Whirlpool Australia thread and has snowballed rapidly into creating a bunch of pretty heavy hitting 3/ 4G routesr, using OpenWRT as the core.
The fundamental objective of the project is to support late model high speed 3G, Cat3 and Cat4 LTE modems to enable them to run at their full 42Mpbs, 100Mbps and 150Mbps potential, whilst router connected.
You may have discussed these connection speed issues elsewhere in your excellent forum.
Very few of the commercial offerings support speeds greater than 25Mbps. One shining example is Sweden's Dovado range.
PPP the traditional Ethernet over USB protocol limits USB transfer speeds to 25Mbps. Different manufacturers use different fast protocols and the one manufacturer may use several different protocols in their product range. However most modems still support PPP as well, so most routers connect just fine albeit slowly.
There is another complication when you move to hostless modems ie ones with a web interface rather than a connection manager.
And there is the universal problem of poor to non-existent modem information, provided by router manufacturers in the router GUI. We all need MDMA style info at our fingertips.
Enter the ROOter.
The ROOter is the brainchild of a bunch of Whirlpool enthusiasts and the deployment is the product of the brilliance of our Canadian programmer, Dairyman.
Read the Whirlpool WIKI for the history and development and link to the current discussion thread.
Visit the brand new open source firmware distribution site maintained by Diaryman (our Canadian guru) where you will find the firmware, along with detailed information and tutorials. There are details to make your own build or simply download the appropriate router bin file and flash your router.
We have learned much in our short journey.
Please drop into the Whirlpool thread and say hi.
I will also endeavour to field answers to any questions in this thread. Although I am no expert, I have watched the ongoing development with true wonder.
Because I am new around here I am are not yet allowed to post links. :(
So ... Google search for 'Whirlpool openwrt WIKI'
Some kind mod may fix the links?
