Observe the following points:
Strong magnetic fields nearby or radio wave interference can be
a problem. Keep the MSR 900 series routers and the user
terminals away from strong magnetic fields and electrical devices
with strong electric fields.
Materials such as cement and boards may partially or totally
block radio signals. It is recommended to install the MSR 900 in
open spaces.
The user terminal is far away from the MSR 900. Move the user
terminal closer and try again.
Lightning strikes may also cause interference in WLAN
connections.
