Im using 3G modem as backup connection together with Sophos UTM. On 1d4 it worked fine, modem detected,worked everytime as needed. Today i made upgrade to 2c4 and modem got not detected at all, only LED for miniPCIe is light up as there is modem present. The same modem works in 1d4,moved to 2c4 does not...It is some kind of BIOS issue?
Edit: i forgot... It is Sierra Wireless MC8775,old HSDPA modem...
