Hi please can someone help .my broad band router has started shutting itself off .if you turn it on again it lights up and starts to reconnect and then shuts off if you leave it after a few seconds it comes back on again and goes through the whole process again and you think its going to work and then shuts off again it did this on tuesday evening and eventually it worked and has been fine up to this evening but now i cannot get it to work at all it just shuts off every time .
