5. TROUBLESHOOTING

PROBLEM SOLUTION

The adapter does not work properly.	Reconnect the wireless USB adapter 11N to your computer's USB.Then right click on my Properties. Select the Device Manager and click on the network adapter. You will find the adapter if it is successfully installed. If you notice the yellow exclamation mark, the resources are in conflict.You will see the status of the adapter. If a yellow interrogation mark appears, please check the following:-Make sure that your PC has a free IRQ (Interrupt ReQuest) (interrupted request) (a hardware interrupted in a PC).- Make sure that you have inserted the correct adapter and install the appropriate disk. If the adapter is not working after trying the above steps, remove the adapter and do the following:-Uninstall the software from your PC's drive.-Restart your computer and repeat the hardware and the software installation as described in this user guide.
You can not communicate with other computers linked in the infrastructure confi guration.	-Make sure that all related devices are switched on.-Make sure that your adapter is configured on the same channel and the same security options as with the other computers in the confi guration of the infrastructure.
What can you do when the computer with the installed adapter is not connected to the wireless network or the Internet?	-Check that LED indicators to the broadband MODEM are indicating normal activity. If there is a problem with band connection broadband.-Check that the LED on the wireless router indicators is functioning properly. If it is not, check that the power cord and Ethernet cables are securely connected.-Check that the IP address, subnet mask, gateway and DNS settings are correctly entered in the network.In infrastructure mode, make sure that the SSID is specified in the settings for wireless visitors and access points.In ad hoc mode, both wireless visitors will need to have the same SSID. Please note that it will be necessary to configure a client to establish a BSS (Basic service Set) (basic service set) and wait briefly before configuring other visitors. This prevents several visitors to try to establish a BSS at the same time, which can result in a multiple BSS being established instead of a single BSS with multiple associated visitors.Check that the network connection for the wireless visitors are properly configured.If security is enabled, ensure that occurrences of the number keys are entered both the adapter and the access point.
