Appendix A: Troubleshooting

This chapter provides solutions to problems that may occur during the installa- tion and operation of the Dual-Band Wireless A+G Notebook Adapter. Read the descriptions below to solve your problems. If you can’t find an answer here, check the Linksys website at www.linksys.com.

Common Problems and Solutions

1.My computer does not recognize the Adapter.

Make sure that the Adapter is properly inserted into the PCMCIA slot. Note that the card can be inserted either way, but is correct only when it is insert- ed with the arrow on the front of the card up. If in doubt, try inserting the card both ways. The card will slide in further when it is correct.

2.The Adapter does not work properly.

•Reinsert the Adapter into your notebook’s PCMCIA slot. A beep should be heard if the card is properly inserted.

•For non-Windows environments, make sure that a PCMCIA card service driver is installed on your PC.

•Open the Control Panel and click on the PC Card. Check whether it has a PCMCIA card in one of the sockets or not. If you find the Adapter in one of the sockets, it means the card has been detected properly. If you see a yellow question mark, the resources are conflicting.

•Right-click on My Computer and select Properties. Select the device man- ager and click the Adapter. You will find the Adapter if it is installed suc- cessfully. If you see the yellow exclamation mark, the resources are conflict- ing. Click PCMCIA card and then click PCMCIA card service. You will see the status of the Adapter. If there is a yellow question mark, please check the following:

•Make sure that your notebook has a free IRQ.

•Make sure that you have inserted the right card and installed the proper driver.

If the Adapter does not function after attempting the above steps, remove the card and do the following:

•Uninstall the driver software from your PC.

•Restart your PC and repeat the hardware and software installation as specified in this User Guide.

3.I cannot communicate with the other computers linked via the Ethernet in the Infrastructure configuration.

•Make sure that the notebook PC to which the Adapter is associated is pow- ered on.

•Make sure that your Adapter is configured on the same channel and with the same security options as the other computers in the Infrastructure configura- tion.
