Hi

I've got an Archer MR 200 and use a 4g/3g sim card to access the internet I use it for remote monitoring some devices where other internet access is not practical.

I'm in Australia and they are shutting down the 3g network and the 4G uses B28 (700mhz). My carrier (Telstra) tells me that this device will not longer work on the network (I assume its only been using their 3g network though it still works well enough for my purposes).

Can I do anything to upgrade the device to use B28(700mhz)?

Failing that does TP-Link have any other modems that support a sim card with LTE4 B28 (700mhz) band?
