I went in my wireless router and changed the IP's to 22.214.171.124 & 126.96.36.199 but when the roku poowers up it searches a minute and then immediately says "can't connect." Nothing I select on the remote changes this during or after it arrives at this point. After a while it then shuts down. Any ideas?
Those IPs are for Domain Name Servers, so hopefully you change whatever was there, and not your actual device IP. A typical home IP should look something like this 192.168.1.1, or some variation of those last two.
You could start off by using dhcp setting which will assign unused IPs when a device needs one. If there is a need to have one stay assigned to the roku, then it could be reserved in the router so it always gives your roku the same number.
That is exactly the process to change your dns addresses to those google dns IPs. If you are getting internet on other devices I'd power roku off and back on, go into network setup menu and report what you find.
If you reset it, you'll need to recreate your home wifi name and password. Just FYI.
The router doesn't explain why the remote isn't working now.
Probably the better advice is to scrap that old roku 2 and enjoy a newer model. My brother in law just replaced his older roku with the new roku soundbar and says it's amazing.
The Roku was given to me by someone who got a truly smart TV. My TV is new but turns out to be only semi-smart, and can only by itself run pre-loaded apps
