1
Check the hardware connections, and make sure the LED is behaving as expected. See the Quick Start
Guide and
Section 1.5 on page 8 .

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 LED, and check Section 1.5 on page 8 . If the
NAP 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 is weak, try moving the NAP closer to the NAP (if possible), and
look around to see if there are any devices that might be interfering with the wireless network
(microwaves, other wireless networks, and so on).
3
Reboot the NAP.
4
If the problem continues, contact the network administrator or vendor, or try one of the advanced
suggestions.
5.5 Wireless Connections
I cannot access the NAP or ping any computer from the WLAN.
1
Make sure the wireless LAN (wireless radio) is enabled on the NAP.
2
Make sure the wireless adapter (installed 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 NAP’s active radio.
4
Make sure your computer (with a wireless adapter installed) is within the transmission range of the NAP.
5
Check that both the NAP and your computer are using the same wireless and wireless security settings.
Hackers have accessed my WEP-encrypted wireless LAN.
WEP is extremely insecure. Its encryption can be broken by an attacker, using widely-available software.
It is strongly recommended that you use a more effective security mechanism. Use the strongest security
mechanism that all the wireless devices in your network support. WPA2 or WPA2-PSK is recommended.
