constant dc's since happening since last patch

[namidairo9]

before last patch i would rarely dc unless i decided to close the browser myself or my wifi went out. after the most recent patch i keep getting an error saying login authorization fail and dcing me from server at random times making it difficult to do certain events like iob, ladder, wrangle fruit delivery, afk grinding while i want to sleep and even dungeons since if i dc i lose my entry. this is occurring on 2 different accounts of mine and is happening between 5 to 10 times a day. (if it matters char is namidairo and server is 107)
