Why is Optus mobile data coverage so much better in regional Victoria for an older portable wireless modem with internal antenna such as a ZTE MF910 (IMEI: 86415402), than it is for a newer non-portable wireless modem with external antenna such as a TP-Link TL-MR6400 (IMEI: 86778702)?

TP-Link TL-MR6400 isnt an Optus sold device.
Unless you have the APAC V3 Version of the TP-Link TL-MR6400 you wont get band 28 which is 700mhz - most critical for regional coverage in Australia.
ZTE MF910 has band 28 700Mhz.

Thanks, this turned out to be exactly the reason why I couldn’t get 4G connection on my TP-Link modem. The nearest tower to me offers 4G on the 700 MHz frequency, and my TP-Link TL-MR6400 V2 wasn’t able to use that frequency.
I have swapped to a DLink DWR-921 C3 modem, which can use the 700 MHz frequency, and I can now get an Optus 4G connection.
