10.4 Internet Access
I cannot access the Internet.
5 Make sure your mobile access information (such as APN) is entered correctly in the WAN screen.
These fields are case-sensitive, so make sure [Caps Lock] is not on.
6 Make sure your SIM card’s account is valid and has an active data plan. Check your service contract
or contact your service provider directly.
7 If the problem continues, contact your ISP.
I cannot access the Internet anymore. I had access to the Internet (with the WAH7003), but
my Internet connection is not available anymore.
8 Reboot the WAH7003.
9 If the problem continues, contact your ISP.
The Internet connection is slow or intermittent.
1 There might be a lot of traffic on the network. If the WAH7003 is sending or receiving a lot of
information, try closing some programs that use the Internet, especially peer-to-peer applications.
2 Check the signal strength. If the signal strength is low, try moving the WAH7003 closer to the ISP’s
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).
3 Reboot the WAH7003.
4 If the problem continues, contact the network administrator or vendor.
10.5 Wireless Connections
I cannot access the WAH7003 or ping any computer from the WLAN.
1 Make sure the wireless LAN is enabled on the WAH7003.
2 Make sure the wireless adapter (installed on your computer) is working properly.
