The LH1000 has terrible thermal management. Under heavy load (streaming 4K + downloading a game), it gets hot enough to throttle. The CPU will slow down, and your speeds will drop by 50%. The fix? Put it on a laptop cooling pad or aim a small USB fan at it. Seriously.
At first glance, the LH1000 looks like an air purifier or a modern Bluetooth speaker. It stands vertically with a grey fabric wrap (on the T-Mobile version) and an LED strip that glows white (good signal), yellow (okay), or red (poor). arcadyan lh1000
T-Mobile hides the advanced cellular metrics. Navigate to: http://192.168.12.1/TMI/v1/gateway?get=all (Note: This endpoint varies by firmware, but for most LH1000/KVD21 units, this returns a JSON file with signal-to-noise ratio (SNR), RSRP, RSRQ, and band info.)
