Did that help at all @charleville?
If you followed these instructions
http://community.48months.ie/t5/The-Knowledgebase/My-Internet-is-not-working/ta-p/45928
and your configuration settings are definitely correct but data is still not working for you then you need to contact 48 support for more advice/assistance.
Hope this helps.
