Disconecting

Good morning everyone.
I got a problem with 1 char in iSro.
I have 1pt 8/8 and the cleric keeps dc 5 sec after login. But I notice this happens mostly when the bard is not at spot so he got no mp to buff.
Is there anything I can do? As it get disconnected so many times at spot so won’t get xp anymore becouse of fatique and after few dc’s I get ip ban.
Thanks alot
