Is a TiviMate 401 error related to my internet connection or Wi-Fi signal strength?

Generally, no. A 401 error specifically indicates an authentication issue with your IPTV provider's server, not a problem with your internet connection itself. If you had an internet connection issue, you would likely see different error codes (e.g., network errors, timeout errors) or no connection at all. However, a very brief, intermittent connection drop *while trying to authenticate* could potentially lead to it, but the root cause is almost always credentials or subscription status.
