Video Game Lunatic<p>I work in an area that has a lot of radio interference (secure facility all staff wears a duress alarm). It's particular, every evening as the sun begins my mobile data degrades to the point where I can no longer stream music, podcasts, etc. Any ideas why this happens?</p><p><a href="https://mstdn.social/tags/streaming" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>streaming</span></a> <a href="https://mstdn.social/tags/radiointerference" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>radiointerference</span></a> <a href="https://mstdn.social/tags/mobiledata" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>mobiledata</span></a></p>
