Example: If your device only supports 802.11b or 802.11g and it can’t connect to the router then you can try to change the 802.11 mode to solve the problem. If your devices all use the same 802.11 standard, you can set an ‘only’ mode to improve performance.
Step 1: Open an Internet browser (such as Internet Explorer) and enter http://dlinkrouter, http://dlinkrouter.local or http://192.168.0.1 into the address bar.
