"Attempting to Reconnect..." while Internet is fine

Two nights in a row (hasn't happened during the day, not sure if coincidence) I have lost control of my champion and gotten the "Attempting to Reconnect..." message consistently throughout all games played. Reconnecting and restarting the client do not fix the issue, waiting it out is the only way; and of course by that time I would be several levels, dozens of cs, and more than likely a couple kills behind (because in ranked there is no honor, only LP). When the bug triggers, initially I am able to see everything happen in real time. I may even be able to get off a spell or an auto attack, but not move. Not visibly anyway, who knows what happens on others' screens. As it persists, however, the game begins to stutter and eventually all characters come to a standstill until the spike is over. My Internet doesn't seem to be the issue, as everything else works just fine. It doesn't appear to be related to game activity, as the bug triggered both in lane and at the fountain. I'd love for this issue to be fixed, it makes me not want to play for fear of dealing with the soul-crushing frustration of watching my champ sit in lane auto-attacking minions and knowing that my opponent(s) are probably in the process of killing me. It's already cost me 2 or 3 ranked games.
