another day another server problem

i moved my server to a location with fibre as my broadband started going really slow. As usual i opened the ports on the router and it works better but for those with boxes that can only use an N line cannot login. my oscam says in the log

client connected to 10000 port
2014/06/01 10:50:33 15F8090 c xxxx (0963&000000/FFFF/C4EF/5F:CAD73D51B44BC7370234590E582D4250): cache3 (244 ms) by xxxxxxx (L/2/2/2) - Ary Digital UK (wait_time over) (cwc NDS OK)
2014/06/01 10:50:33 16C8930 c encrypted newcamd:10000-client 11.111.111.111 granted (ppppppp, au=off)
2014/06/01 10:50:33 16C8930 c user ppppppppp authenticated successfully (mgcamd)
2014/06/01 10:50:33 16C8930 c init for reader xxxx not finished -> reject client
2014/06/01 10:50:33 16C8930 c encrypted newcamd-client 11.111.111.111 rejected (login failure)

the port is open for newcam and cccam peers can connect ok to their port. i didnt change any configs on the server

even upgraded oscam to 9754 and still no difference. why would it say login failure. ive never seen that before or had any bother like this

well seein as no one has had this problem before i''m going to uninstall oscam and reinstall. what is the Ubuntu command to uninstall the oscam package please

done that already but still the same problem. can login using newcamd protocol of cccam but not mgcamd. get that login failure message. looks like I need to rebuild including ubuntu
