A friend of mine has used my teamspeak for over a year, and suddenly his connection is dropping in and out and can't hold a connection. He's tried disabling firewalls, reinstalling teamspeak clearing cache, increasing security levels, I've raised codec delays on the server channels, I've lowered security for the teamspeak, I've allowed members to log in an infinite amount of times so it doesn't stop him from reconnecting if he disconnects too soon, but the problem still persists. His internet is stable and it is only happening on our server. We've tried multiple other servers and they all work fine. Does anyone have any idea what could be causing this problem?

Here is the client log:
