Quick Solutions
Still having issues? This is usually the deeper cause below.
If the hub reconnects then drops every few minutes, check for an IP conflict — two devices sharing the same DHCP address fight each other continuously.
Controlled join conditions prevent repeated orphaned pairing attempts.
Hub disconnections that cycle repeatedly are almost always IP conflicts — two devices fighting over the same DHCP lease after a router restart.
