game freezing and long r0 periods

[ejiboo]

for the last week or so randomly, with full wifi strength and no apparent reason my game will R0 for upwards of 10 minutes (that's the longest i've waited) without responding or disconnecting, sometimes restabilizing itself at very random intervals. this can happen only once in a while or once every 10-15 minutes, in any area. i have never had this problem before. very annoying when crafting!!!

edit: i r0 but never disconnect <--

recently i was trying to reposition one of my retainers and now, whenever i try to call that retainer my game will freeze. i have to disconnect my wifi for the game to log me out. i've tried restarting my computer, switching areas multiple times and even calling the retainer at a different ward. my game freezing with calling this retainer is a separate problem but also one in the same because it replicates the problem-all of the other times stated in the previous paragraph are totally separate!

why is this happening!?
