It controls Fire OS, and Fire OS in turn controls whatever app sits on top of it, including your IPTV player. Directional buttons move the on-screen cursor, select opens whatever's currently highlighted, and the back button exits menus, exactly the same as it would for any other app on the device. It does not talk to your IPTV service or the underlying stream directly; there's no dedicated channel-up button the way an old-style cable box remote used to have built in. Playback controls like pause, rewind, and fast-forward pass straight through to whichever player app happens to be open, so the exact behavior can differ slightly from one app to the next depending on how each one maps those buttons.

The remote has no physical keyboard at all, so entering a host address, username, and password means clicking through an on-screen character grid one letter at a time using only the directional pad. For a typical Xtream Codes login that adds up to dozens of individual selections, and a single missed tap usually means retyping the whole field from scratch. It isn't a bug or a design flaw, it's simply what a nine-button remote was ever built to handle well. Two things genuinely fix it: the free Fire TV mobile app, which turns your own phone into a full keyboard for the stick, or a small Bluetooth keyboard paired directly to the device itself.

Hold the Home button down for about 10 seconds while standing close to the Firestick itself; a pairing prompt appears on screen once the connection succeeds. If a remote suddenly stops responding after a system update, unpair it and repeat the exact same steps rather than assuming the remote itself has failed or needs replacing. Generic third-party replacement remotes pair through this same process as long as they're built specifically for your Firestick's generation, so a lost or broken original remote doesn't mean starting over with anything more complicated than this.
