I’m having issues with a number of X750s deployed in the US (T-mobile). Some work just fine, but others, despite similar signal conditions, have little to no data throughput. I’ve tried switching bands, but that doesn’t seem to help. Here’s an example of what I’m seeing

I’m at a loss for why this could be. Signal looks comparable to what the other devices are getting. I’ve checked with the carrier, the line has no restrictions, no network issues reported locally. All these X750s are running the same firmware and configurations. And yet, a number of them (Nevada, Arizona, North Carolina) are experiencing unusable data speeds. Looking for ideas on what else to test to determine the root cause. Any ideas?
