my roku device will not connect to my wifi I have followed all the steps to try to fix the problem and nothing is working. It has been a week now.
@Alyssap20 change it to b,g,n. Save the settings. Then reboot your modem and Roku
Here is a good guide from @AvsGunnar
Which model Roku express? The model number is written right on the unit. It’s also found by going to settings/ system/ about. If you have the base model Roku Express it only connects to the 2.4GHz. You need to reconfigure your modem.
