Trouble Shooting

This chapter provides solutions to problems that may occur during the installation and operation of PCI express Adapter.
Read the descriptions below to solve your problems.
1. The PCI express Adapter does not work properly.
Reinsert PCI express Adapter into your PC's PCI slot. Right click on My Computer and select Properties. Select the device
manager and click on the Network Adapter. You will find PCI express Adapter if it is installed successfully. If you see the
yellow exclamation mark, the resources are conflicting. You will see the status of PCI express Adapter. If there is a yellow
question mark, please check the following: Make sure that your PC has a free IRQ (Interrupt Request, a hardware interrupt
on a PC.) Make sure that you have inserted the right adapter and installed the proper driver. If PCI express Adapter does not
function after attempting the above steps, remove it and do the following: Uninstall the driver software from your PC. Re-
start your PC and repeat the hardware and software installation as specified in this User Guide.
2. I cannot communicate with the other computers linked via Ethernet in the Infrastructure configuration.
Make sure that the PC to which PCI express Adapter is associated is powered on. Make sure that PCI express Adapter is
configured on the same channel and with the same security options as with the other computers in the Infrastructure con-
figuration.
3. What should I do when the computer with PCI express Adapter installed is unable to connect to the wireless net-
work and/or the Internet?
Check that the LED indicators for the broadband modem are indicating normal activity. If not, there may be a problem with
the broadband connection. Check that the LED indicators on the wireless router are functioning properly. If not, check that
the AC power and Ethernet cables are firmly connected. Check that the IP address, subnet mask, gateway, and DNS settings
are correctly entered for the network. In Infrastructure mode, make sure the same Service Set Identifier (SSID) is specified
on the settings for the wireless clients and access points. In Ad-Hoc mode, both wireless clients will need to have the
same SSID. Please note that it might be necessary to set up one client to establish a BSS (Basic Service Set) and wait
briefly before setting up other clients. This prevents several clients from trying to establish a BSS at the same time, which
can result in multiple singular BSSs being established, rather than a single BSS with multiple clients associated to it.
Check that the Network Connection for the wireless client is configured properly. If Security is enabled, make sure that
the correct encryption keys are entered on both PCI express Adapter and the access point.
