Same issue as several others with this restart loop after "updating" software. Have tried all of the suggestions with no change. Thoughts? Thank you.
My Roku Express finally updated. I used a spare router I use for my Jobsite when I setup CCTV cams. I setup my router to have no password, temporarily. Went through setup, downloaded the latest firmware and restarted. To my amazement it worked. I then moved the Roku to the location I wanted to use it and connect to the regular router (the one that previously kept looping) and it worked fine.
I don't know if there was a recent update on the server. I had one theory that the ports may be blocked preventing the update to reconnect to the link server.
I solved my issue as well. After researching the specs of the device, and seeing the antenna was only 802.11bgn, I decided to try something.
Both the 2.4ghz and 5ghz networks on my WiFi router shared the same SSID, which I had been connecting to with the Roku. I changed the 2.4ghz network to a different SSID, connected the Roku, and viola it connected and updated successfully.
If your router is sharing the same WiFi network name for both wireless bands, I would suggest renaming the 2.4ghz to something else, and ensure the Roku is connected to it.
Solved problem by setting router to 802.11g only ---- it had been mixed.
I tried 802.11n only and problem stayed.
Up and running who hoo!!
I just bought a Roku Express today and having the same issue won't get past update. I do have a Roku Ultra which I got a year ago on another tv still works fine.
I had the same problem and have been following this situation. I was able to get it working after 3 weeks of failing. Apparently after the update it (Roku Express et. al.) gets very picky on what type of WiFi connection, but from my solution, using an older 802.11 b/g WiFi connection did the trick. Just as an added measure, I disabled the WiFi Password (temporarily) so it would obstruct the setup process. All other solutions seem to point at the router, though I was skeptical at first because it would connect to the router and save the password. After using an older router that was 802.11 b/g it connected. Then after the link code displayed, and complete the Setup. I was able to reconnect to the Main router that was previously failing after the setup was complete.
What brand and model WiFi Router are you using?
I would suggest you force the Roku to connect to your 2.4ghz wireless network. If you are running both 2.4 and 5 bands with the same SSID, I would rename the 2.4 network to be something unique, and try again.
