No Network lost connection to Tower

[HowTo]

Morning




Did reboot router there after it was fine. Why..............?

 

[LOTR]

Saw this twice today. Around 6.45 this morning and again this evening about 5.15. Red light on router.
Switch off/on - all is well again.
Seems to me like it happens constantly for a few days, then nothing for a week or two - followed by rinse and repeat.
I really should keep a log of these.
