Nighthawk M1 Optus speed slow
I purchased the Nighthawk M1 outright to use with an Optus sim rather than Telstra which is who it's sold by. However, I'm unable to get the speeds that I'm seeing with the same sim via my Samsung S...
carleast01 if you bought the Telstra Nighthawk M1 (MR1100-1TLAUS) then it does not support all the Optus radio bands. Specifically it does not support TDD B40 which Optus use for the Carrier Aggregation. If you really wanted to use an Optus SIM - then my suggestions would be to buy the Optus AirCard 800S which is a CAT11 device (CAT9 out of the box but with a firmware upgrade it is CAT11) and that does Carrier Aggregation with B40, B28, B3 and B7 - all the bands used by Optus LTE 4G currently.
Thanks.
