Chapter 4 This chapter contains a troubleshooting guide for solving common problems you may encounter when using the A202 Wireless USB Key Adaptor.
Troubleshooting This troubleshooting guide provides answers to some common problems which you may encounter while installing and/or using Diamond Digital Wireless LAN card products. These problems requires simple troubleshooting that you can perform by yourself. Contact the Diamond Digital Technical Support if you encounter problems not mentioned in this section. Problem My computer does not recognize the installed A202 Wireless USB Key Adaptor.
Troubleshooting Problem Action I cannot connect to an Access Point (AP). • Check if the Network Type of the device is set to Infrastructure mode. • Check if the device has the same Service Set Identifier (SSID) as that of the Access Point. • Check if the device and the AP have the same Encryption. If WEP encryption is enabled, set the same WEP keys for the device and the AP. • Check if the MAC address of the device is included in the AP Authorisation Table. Ask your LAN administrator about this.
Troubleshooting Problem Action I cannot connect to other computers linked via an Access Point or Ad-hoc network. • Check if the A202 and the other APs and/ or clients have the same Encryption. If you enable WEP encryption, you must set the same WEP keys for the device and the other AP/s and/or clients. • Check the TCP/IP settings (IP address, subnet mask, gateway, and DNS) of your computer. • Enable file and printer sharing in each client computer to allow file sharing.
