I have that same router. What I did is go on to your main computer that has the router connected to it. In the adress bar(where you type in websites) type in 192.168.1.1 once you click enter you will get a pop up saying that it needs a user name and password. Leave the user name blank and for the password admin. After you are in click on the wireless tab. Once there click on wireless network mode and set for mixed. For Wireless Network Name (SSID) set it for whatever you want. Do something easy like the first letter of your last name then net. Mine is qnet for example. For the wireless channel set channel 1. Wireless ssid broadcast set for enable. Then save settings. That it what worked for me, I had the exact same problem.
