Section 5 - Troubleshooting 5. The computer does not recognize the DWA-556 Wireless Adapter. • Make sure that the DWA-556 Wireless Adapter is properly seated in the computer's PCI Express 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 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-556 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.
