9.4 Internet Access

I cannot access the Internet through a 3G/4G wireless WAN connection.
Make sure you insert a 4G SIM card into the card slot before turning on the LTE4506.
1
Make sure your mobile access information (such as APN) is entered correctly in the WAN screen.
2
These fields are case-sensitive, so make sure [Caps Lock] is not on. Check with your service
provider for the correct APN if you don't have it.
Make sure your SIM card's account is valid and has an active data plan. Check your service contract
3
or contact your service provider directly.
If you are using a pre-paid SIM card, insert the SIM card on another mobile device to check if the
4
SIM card still works. If the SIM card works without any problems on another mobile device, contact
the vendor. Otherwise, contact your service provider.
If the problem continues, contact your ISP.
5
I cannot access the Internet anymore. I had access to the Internet (with the LTE4506), but
my Internet connection is not available anymore.
Reboot the LTE4506.
1
If the problem continues, contact your ISP.
2
The Internet connection is slow or intermittent.
There might be a lot of traffic on the network. If the LTE4506 is sending or receiving a lot of
1
information, try closing some programs that use the Internet, especially peer-to-peer applications.
Check the signal strength. If the signal strength is low, try moving the LTE4506 closer to the ISP's
2
base station if possible, and look around to see if there are any devices that might be interfering
with the wireless network (for example, microwaves, other wireless networks, and so on).
Reboot the LTE4506.
3
If the problem continues, contact the network administrator or vendor.
