Internet connecting and then disconnecting every couple of minutes

Check the back of the modem for the DSL ports next to the phone cord. Each DSL port that has a phone cord plugged in should have a solid green light next to it. If this light goes solid and then drops and begins flashing again you have a problem called losing sync. There's either an issue with the wiring in the home but more likely the issue is outside on the cable and a technician will need to fix it. Make sure all your phone cords are in good shape and look for any other wiring that may be damaged. If the issue keeps happening you'll have to contact Telus support.
