Chapter 21 Troubleshooting
LTE3301 Series User’s Guide
137
I cannot access the Internet anymore. I had access to the Internet (with the LTE3301), but
my Internet connection is not available anymore.
1 Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick
Start Guide and Section 1.8 on page 13.
2 Reboot the LTE3301.
3 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. Look at the LEDs, and check Section 1.8 on page 13.
If the LTE3301 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 LTE3301 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 LTE3301.
4 If the problem continues, contact the network administrator or vendor, or try one of the advanced
suggestions.
Advanced Suggestion
• Check the settings for QoS. If it is disabled, you might consider activating it.
21.5 Wireless Connections
I cannot access the LTE3301 or ping any computer from the WLAN.
1 Make sure the wireless LAN is enabled on the LTE3301.
2 Make sure the wireless adapter on your computer is working properly.
3 Make sure the wireless adapter installed on your computer is IEEE 802.11 compatible and supports
the same wireless standard as the LTE3301.
4 Make sure your computer (with a wireless adapter installed) is within the transmission range of the
LTE3301.
