Section 5 - Troubleshooting
5. The computer does not recognize the DWA-520 Wireless Adapter.
• Make sure that the DWA-520 Wireless Adapter is properly seated in the computer's Desktop slot.
• If Windows does not detect the hardware upon insertion of the adapter, make sure to completely remove
drivers that were previously loaded. To remove the drivers, do the following:
A. Under Tools > select Folder Options... > select View > under Hidden files and folders > select Show
hidden files and folders.
B. Uncheck Hide extension for known file types > click on Apply
C. Search for previously loaded driver files. Remove these files from the INF and SYSTEM (DRIVERS)
folders in the Windows directory. Note: Windows XP and Windows 2000 will rename .inf files that
have not received WHQL certification into oem.inf files (e.g., oem1.inf.)
6. The computer with the DWA-520 installed is unable to connect to the wireless network 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.
