Netowrk Problems After Switching Internet Providers

Hello All,

I'm having an issue where my internet is only working for a few minutes and then is cutting out with the only way for me to re-store it (that ive found so far) is to go into the command prompt and do a ipconfig /release and /renew to get it working again for a few mins. It is happening to every workstation after the compnay switched over from dsl to broadband. Now I didnt do the switch but from what I could tell all our equipemnt (router, switch) configuration remained the same outside of the new modem being in place of the old one. I have full access to our network system and if I can get a little guidence on maybe some possible solutions I can try and fix it over the weekend while it wont effect anyone's work.

Ill be checking back frequently if anyone has questions.

Thanks everyone
