Hi,
So my Roku Express I bought last year has been working great for months, up until about 2 weeks ago. All of a sudden, certain channels will not connect. In fact, the only channel I know that works now is PBS Kids and Pluto. The Roku channel opens, but just times out, the same with Amazon Video.
The Roku itself, if hard reset, will connect to my wifi and pass the connection test, but will not retrieve a activation code, UNLESS I tether it off my phone. I know about 5 other customers have the same problem with smart devices, ie. Roku's, SmartTV's, Firesticks.
I don't think it's an IP related issue, because Laptops, Tablets, Phones on this router wifi can connect to Roku and Amazon Video just fine.
My question is, what kind of traffic is getting blocked? If PBS kids works fine, what kind of protocol does it use different from say the Roku channel. And what link is the roku trying to reach to pull down an activation code.
Thanks
Thanks for the inquiry.
Have you made any changes to your wireless network recently? Please be aware that the Roku Express is only compatible with wireless b/g/n networks on the 2.4 GHz spectrum. Have you tried changing the wireless broadcast channel on the router to see if this will allow your device to connect to the internet?
If you have factory reset and are not getting an activation code, we recommend rebooting both your wireless router as well as trying to connect your device to an alternate network or mobile hotspot to get your device set up again. Once activated, try reconnecting to your wireless network.
Please keep us posted.
Thanks,
Danny
Thank you Danny for the follow-up, it actually turned out to be my MTU. As I mentioned, my setup worked for months, and it might be coincedence but I started having trouble a week after my ISP had some trouble. Also, I was always able to tether off my phone and pull an activation code or just use the Roku normally, so I really figured it was something with my ISP. Regardless, setting my MTU down to 1460 made everything start working again great. Same for other users around town.
I'm having the same issue. On which device did you change your MTU?
MTU is a setting in your router, but I'd be surprised if that was really the cause of the problem.
I adjusted the MTU on the WAN settings in my router, I believe, not 100% sure because my ISP seemed to fix whatever problem they had a few weeks after, and I've since set it back to 1500.
The other customers who had the same problem had luck with 1450 MTU, but I'm not sure how they concluded that was a better setting.
