Jason0u, the TV controls are completely separate from the Roku controls (unless you're using CEC which you're apparently not), so it's possible for them to work while the Roku controls do not. The Roku controls use Wi-Fi Direct which in general takes more power than simple IR, so if you haven't given new batteries a try you should. It's also possible for the remote to lose its pairing in which case the TV controls will continue to work, but the Roku controls will not. You may want to try pairing it again if new batteries don't fix it.

New batteries.  Why didn’t I think of that.  That’s like calling tech support and them telling you to restart your computer.  The very first line of the troubleshooting tree.  Thanks. 
I changed from the 5ghz network to the 2ghz network and it started working again. So it wasn’t a battery issue thanks. It is a connectivity issue. Nothing with my network changed on the 5 ghz band so there really shouldn’t be a reason for it to suddenly drop connectivity or lag as it has been. Other than hardware problem. But what do I know.
