Find the problem
5G with full bars but slow?
The bars measure radio signal to the nearest tower. They say nothing about what is behind the tower - and the "5G" icon itself hides two different networks. Two rows in Radien and one ping tell you which situation you are in.
1. Read the Radio row
Open Radien's status card on cellular, then Network Details. The Radio row says what the status bar rounds away:
- NR: real standalone 5G, radio and core both.
- NRNSA: a 5G radio riding the 4G core network. The icon says 5G; the speeds are often honest 4G. Nothing is broken - the network simply is what it is, and now you know its real name.
2. Measure instead of believing the icon
Open Ping and probe 8.8.8.8 over cellular. Full bars with high or wobbling latency at busy hours is the signature of a congested cell: the radio is fine, the tower is crowded. Clean latency means the connection itself is healthy - and a slow app is then that app's problem, not 5G's.
3. One row for the curious
If Network Details shows a NAT64 row, your carrier translates between address families inside its network. That is normal engineering, not a fault - but it explains why some old-fashioned tools behave oddly on cellular.
What you now know
Which 5G you actually have, whether the cell is congested, and whether the slowness even belongs to the network. Full bars were never a lie - they just answer a smaller question than the one you were asking.
