Sudden disconnect from game/ No error warning messages

Playing games at any time will disconnect from, and kick me out of game completely. Then I have to resign in and start over. Losing progress in raids and other active battles when I'm kicked off. I can't play more than 10 -15 mins at a time before I'm kicked off. I already uninstalled, reinstalled, updated, etc. Nothing has stopped the issue. I've never had this issue before. Playing for 3-4yrs active.
