Wi-Fi & connectivity

[brianberger]

For the past week, my Roku player has been unable to connect to any wi-fi source whatsoever. I have tested with other devices and it is NOT the internet itself. The problem has been temporarily fixed a few times, but by temporarily I mean lasting less than 10 minutes. I am at a loss for what to do. I do not know what information I need to specify to even hope to be helped, save for that it is version AEA.50E04201A. I also cannot install updates due to being unable to connect.

If you have Comcast/Xfinity or Cox as your ISP ensure your wireless mode is set to b/g/n and not g/n. For Comcast/Xfinity:

I... don't even know what any of that means. Would mentioning that my housemates' Roku devices are able to connect to our wi-fi just fine make any difference? It's just mine doing this.

You don't know who your Internet Service Provider is?  That may be irrelevant if other devices are connecting, but it would still be nice to know along with some other information.  What's the model number displayed under Settings->System->About?  If it's a device that uses a USB cable for power are you using the supplied power adapter and not your TV's USB port?

I know my provider. It is XFinity. The information in the link is just a lot to take in and not very coherent to someone such as me with very few technical skills. Like, that may as well be in another language to me.

I'm going to just buy a newer Roku device because I am clearly not equipped to try any of the solutions here, and I don't even trust that they will work due to all the other things I've tried and failed. This issue happened so out of the blue that I'm pretty convinced it's just shot for good. I just want to be able to watch TV again, lol.. Thank you for trying to help me though, it's very kind of you.

It's possible that your roommate's devices support 5GHz and yours only support 2.4GHz Wi-Fi.  If you buy another device that only supports 2.4GHz you may have the same problem.  See if this walk-through helps with changing the Xfinity settings:

Lots of people with Xfinity supplied equipment are having the same problem that you've described and changing the setting fixes it.
