Intermittent faults are awful to track down and very much dependent on the quality of field engineer that looks at the problem. The fault has to be tracked back through and if it has multiple causes solving can be very difficult and costly.
1. Firstly make an assessment of your technical expertise and experience, if you are 'self taught' it is wise to get a professional in to help you. As an IT business during a year we see this across many sites and we get to know our clients which makes it easier to help.
2. Make a log of the outages and duration, confirm this by checking your router stats.
3. Create a dialogue with your Broadband supplier (this is where a professional will avoid being fobbed off without getting mad).
The key to this is to have good evidence and build a clear dialogue with the supplier, keep a record of each time you raise the fault with the supplier and always ask them for the call reference.
On one occasion I dealt with this problem for a client where the supplier (PostOffice) would not/could not resolve the problem and switching suppliers was the only route. The reason switching worked was that the new supplier was prepared to have BT out to replace the local cable. The downside was that the client was off-line for 3 weeks whilst this was sorted out, during that time they were dependent on using a 3G connection.
Hope that helps.
