Having now tested the RUT240 extensively and read all of the past posts on this topic, I have to conclude that the RUT240 just isn't capable of connecting at speeds anywhere close to what it should (or at least what I expected).
DL speeds of 1 - 10MB DL is what it delivers, where my phone (connected to same mobile service in the same location) delivers anything between 50 and 80MB, depending on where it is.
I understand the limitations of CAT4, but with every post reporting exactly the same findings, it's clear that the RUT240 is built to a price point, rather than a performance point.
This is a shame ... it's small, configurable and very flexible, and I'm sure its speeds would be fine for some applications, but if you're hoping to stream TV etc, it just can't deliver the speed.
Can anyone recommend an alternative 4G router which can be powered from 12V and take an external antenna?
