Same network, phone app doesn't work now
I'm having this exact same problem. Both my roku and phone are on same wifi. I entered the ip address manually on the roku app....exactly and it says no roku device found! I've restarted both devices and still the exact ip address says it does not exist despite being right in front of me on the screen. I've never had any issues before up until now. Even more frustrating is it only seems to be able to connect to eachother if one is on the 5g network and the other on 2g. This makes zero sense since the 2g and 5g are on seperate SSIDs. My phone cannot be on 2g bevause that's horribly slow and Mt TV keeps telling me to switch networks because the 2g signal is so poor. So why is ir that neither of the two can connect to eachother when they are both on the 5g network? This is also is the case woth youtube and any casting for that matter. None of it works unless my phone and TV are on opposite networks.... and I cannot afford either to be running on 2g.
