media dissconnected

hello guys i am stuck my internet has been working fine for 9 months since i moved house

few weeks ago i could not get online so i checked cmd/ipconfig and it says that media state media disconnected now it takes me hours to get online each day

i have a windows 7 laptop and a windows xp pc and a xbox 360 all on the network and non of them will work

i tried a new router which worked for about an hour then gave the same error

please help me i have followed about 30 things on google and nothing

also my laptop is wireless and xbox and pc are on a wire and they face the same problem

 

Is your router the only thing between your computers and the cable/dsl line, or do you have a modem as well?

 

i did have my talktalk modem but i just purchased a modem and router all in one and still same problem
