Re: Error code 18 issue also

Having the exact same issue.  Recently got a new mesh router system, and everything else in my house works except for all of my Roku devices, and I have four. Signal strength is excellent for network, but all my roku devices say download speed is poor even though I repeatedly test my Internet speeds and they’re consistently 250+ MPS.   I can find no definitive help on any of these forums other than “restarting your Roku or your router“. This does not work.

Re: Error code 18 issue also

I ran into this Error Code also -- but I have no idea how it might've happened.

I tried the trick of running the Roku unit (4660X2) from the Mobile hotspot, and it worked fine -- so I turned my attention to the router.  From the router log file, it looked like there was a problem with authentication on that device...

Instead of playing with different setup parameters, I just did a reset of my router to the factory settings (with firmware updated).  After that, the Roku unit did just fine over WiFi!

Looking back, I think the issue was that I had set the router's Security Mode to WP3, which my old Roku unit probably didn't understand.  When I reset the router, it came up set to WP2 by default.  With the router's Security Mode set to WP2 or WP2-WP3, everything worked just great!

Since I didn't see any other solutions in here, I hope this helps.
