These types of problems can be very tough to troubleshoot. Begin by checking the following:
1. Filters - DSL Modem should not be filtered. Everything else should be filtered (phones, answering machines, alarm systems, water meters, Satellite receivers if hooked to phone line, etc.) Try unplugging everything but the modem itself. If the problem is fixed, most likely one of the filters is bad.
2. Electrical Noise - Bug Zappers, Treadmills, Dimmers, Vapor Lights, Halogen Lights, Street Lights (not only yours but your neighbors too)
3. Internal Wiring - Check for broken wires, recent changes to anything inside your home (new phone, new electric outlet, new electronic devices).
4. Faulty modem - This is rare but the modem itself could be going bad.
5. NID check - Try plugging the modem in at the NID to help eliminate inside wiring being the issue.
6. Half Ringer - Some NIDs have a half ringer inside. If you have one, it should be removed as they generally degrade DSL performance (line stats will show this). »Residential Install with PICTURES!!!!!
7. Outside Wiring - Construction in your area?, Squirrels?, Recent car accident?, Trees?
8. Detailed modem logs are the biggest help. Note the days, times and frequency of the drops. Logs from 5100, 4100 and 2Wire modems will help show whether the actual DSL signal is dropping or the PPPoE session is dropping. Don't forget to post the line stats that are in the modem as well.
Also note if your dial tone drops as well during this time.
The more detail you have, the better.
