What to do if a PC in the LAN cannot access the Internet?

•If the power indicator is off, you need to check whether the power adapter is normally connected.

•If the signal strength indicator is off, you need to check whether the area is covered by the network.

•If the area is covered by the network, you need to check whether the network mode is correct. For information about network mode, see "Mobile Network Settings".

•If the indicator of the Ethernet interfaces blinks, the corresponding Ethernet interface is normally connected. If the indicator is off, you need to check and ensure that the related Ethernet connection is normal.

•You must configure the correct PPP user name and PPP password when you access the Internet through the device. Check whether they are correct, and see "Configuring PPP Profile Settings" for details.
