It's second time it's happened, had 2degrees for about 8 months.

Unplugging and plugging back in Fritz fixes it. The WLAN light flash's like mad - 2 to 3 times a second and no device can pick up a wifi signal.

Internet is still working as phone calls were made while in this state on Phone Plus.

Have goggled, but results only return about power light flashing. Unplugging fritz deleted the logs so I will plug something in with ethernet and look at logs next time before unplugging.

Is it anything to worry about or is it something expected for something constantly plugged in?

Cheers.
