The question I have is,
1. Did you have sync previously and it has suddenly stopped working?
2. Is this new a new DSL activation of service to your address and has not achieved sync yet?
The most common issue is usually a recent change within the telephone environment or equipment at your address, does any of the following fit your scenario: You recently moved your DSL equipment to another room, you have bought a new phone, answer machine, Fax machine, Sky television subscription, a monitored security alarm service has been installed at your address or health monitoring equipment has been installed or an unlikely, lightening strike or power outage has occurred around the same time as sync was lost.
Any of the previous changes may have altered the way DSL signal is being filtered or split from your standard home phone signal, all telephone line using devices except for the modem/router will need to have its own DSL filter, if security or health monitoring was installed you will need to contact your internet provider and request a line splitter installation (this can be at some cost to the user, so don't forget to check what a local electrician can do this same job for)
DSL Filters can also be very susceptible to problems after power surge/failure or lightening strike at your address. Or if you have recently moved your DSL equipment, please double check the way you have setup the filter and cables at its new location.
The only test required to verify the issue is not at your address is known as an ISOLATION TEST. The router must be checked in a Phone signal free environment, please remove all phone cables from all jack-points within your premis and plug in only your router, without a filter, you should also test your router across all the jackpoints at your address if the first phone-jack you try fails) If we got lucky, you now have sync and the problem lies with one of your phone line using devices or the filter that it is using, start plugging each device back into the phone circuit one device at a time, with a filter and check to see if the router has lost sync after each device is plugged back in until you are able to identify the problem device, filter or jack-point.
Follow the directions exactly as above and if no problem devices, filters or jack-points are found, then ISOLATE your router again and call your ISP provider and request firstly a "port reset" for your DSL port, this should be achieved within a 24Hr period, some are able to do this within 20min of your call, if sync will still not come up it is time for the ISP or service provider to send out a technician to verify the issue is not at the port, cabinet or exchange, this may take some providers up to 5 days to achieve.
Some last thoughts,
Dont rule out the possibilty of the Phone cable used for the router has failed (test the cable on a working home phone to verify it is still working)
or you may have bought an extension cable for your router, the length of Ph cable between your router and the jack-point can be no longer than 5meters before DSL signal fade can start to occur, the router will work at its best with a 15cm-30cm Phone cable, the 1meter cable usually supplied is fine.
Also, do check the jackpoints that you are NOT using at this premis (rare occasions have found me resolving sync issues because the vaccum cleaner has taken out one of your unused jack-points under the bed, in the spare room or the neighbours visiting toddler has tried to plug in a jam sandwhich or even a small plastic toy of some sort into an unused jackpoint)
If you are able, do check that your router can get sync and connect Ok at an address where DSL signal and Sync is currently known to be working.
If you have just moved to this address and your property is over 40-50Yrs old, you may want to check with the phone line provider to see if "line insulators" have ever been installed previously to resolve line noise issues, ageing line insulators will corrupt your DSL signal especially on the high humidity days.
I realise this must seem quite broad and intensive, this testing is intended to rule out any possibility of the issue being internal to your address (as we all know TELCO technicians are all too eager to hit you with unexpected maintenance charges if the issue is found to be internal to your property, as opposed to external)
Hope this gets you closer to identifying the source of your DSL sync issues, if you are like the many DSL subscribers out there, you cant stand to be without your high speed internet for more than two minutes either.
