Dear IT Experts,

I hope you are all doing well. Yesterday, I was working on my  msc project management research topics when my TP-Link router was working perfectly. Suddenly, it stopped working, and upon checking, I noticed it was blinking. I contacted my internet service provider, and they confirmed there was no fault on their side. Therefore, I'm reaching out here for help. Your suggestions and replies would be highly appreciated. Pictures are provided below.

Thanks in advance.
