Router TP LINK - no internet access for few seconds. Question.

Hello. My router TP LINK. Have an question. Connected to wall. Laptop wifi. Yesterday get No internet access for only 5-6 seconds and then internet back and no issues.
Is this something with router , or ignore this?
I ask because 2 weeks ago i had power out due to washing machine that tripped RCD. So it was because this maybe or this doesnt matter?
