I saw that L860 modem is supported by GLiNet modems (ROOter by Of Modems and Men )
How ever, router only see carrier name and did not connect to internet. I updated modem firmware to 18600.5001.00.35.01.57_5026.01 but no luck. Model name and Imei are not displayed on UI, however i could see imei from AT Command
SFT1200 is not supported by ROOter.
ROOter has extra drivers included.
