Update Firmware Netgear M1 (MR1100-1TLAUS)

Hi Guys & Girls,

Anyone able to solve the non existent Telstra Carrier Aggregation on this unit? I have the latest PRI 5.05 / firmware NTG9X50C_12.06.08 on the MR1100-1TLAUS but seems to have really slow uploads suggesting only single band.

Do I need to move house or install a booster in Brisbane QLD AU to be able to get two towers?
