Recently upgraded to a new device. Connected to the network and worked fine for a week. Now when I try to connect I cant find the network, and the networks that show up have very low connection. Turned off, and back on. Didnt help. Tried connecting to my phones hot spot, same problem. Connection comes up low on the roku, and wont connect to network. Unplugged my new roku, plugged my old roku back in, my network shows, with full signal, as does 6 other networks, and a Verizon hotspot all with full signals. Tried my phone, phone network shows, full signal, and connects. Plug new roku back in, 3 of the 6 networks show, all with 1 bar for signal strength, and my network isnt one of them. Try phone again, 1 bar signal strength, no connection. Do I have a bad roku? What's the next step?
