3. Wait until the network is fixed if your router performs poorly in wireless networks that might result from network
congestion.

1. Modification of the router configuration/settings will cause non-resumable disconnection of the device. Delete and
add the devices again after factory reset following steps in Q1.
2. Unstable network signal could cause disconnection of the device. Wait for about 2 minutes for automatic
re-connection. If the connection does not resume after a while, power off PM2/E and then put it back on. It shall
re-connect automatically.
3. If the above is not effective, delete and add the devices again after factory reset following steps in Q1.
