I'm having trouble connecting my Roku player to my E4200 router. The Roku recognizes the wireless network but won't connect when I enter the network passcode. Looking in the router, I see the Roku's MAC address in the list of devices, but it won't connect. Any ideas?
It sounds like it might be an encryption issue. My first suggestion is to log into the router control panel and click on the Network link. Scroll down to the wireless section and change the following items values:
Channel Width - 20MHz
Security - WPA/WPA2 Personal
Encryption - TKIP/AES
Next click on the "Scan" button at the end of the Channel option and after it has finished, choose a channel that has not other wireless device showing.
Save at the bottom.
