The Roku 1 uses an IR remote, so a replacement isn't that expensive. In fact, you can probably go into a local store that sells generic remotes and find one that list support for Roku devices for about $10 or so. But first, make sure your remote batteries are good, and inserted correctly. Different Roku remotes have different battery orientation.
But since the Roku 1 is WiFi only, you have to connect it to the wireless before you can use a phone app. There's no other way to connect it to a network without a remote. Unless you know the WiFi SSID and password of the last network that it connected to, and change your WiFi to match. In that case it should auto-reconnect.
