Modem/router is only a few weeks old, was able to login several times using defaults of admin ID and password PS, now get authentication failure. Did a power cycle and a less than 15 sec reset, did not fix, did not change password ??
Try clearing the browser cache, if no good, try a factory reset. (Hold the reset button in over 15 seconds), you will lose any settings in the router. If that fails call the tech's at 800 363 2416 Let us know how it goes, thanks...
A reset to default should not bother your phones, other than when the gateway is temporarily unavailable while the reset is happening. It will, however, remove ALL of your router specific setttings.
If you still have a problem after the reset or don't want to do it yourself, call the folks at 800-363-2416.
