Netgear C6300

Hello, 

I live in Texas and recently experienced a power outage for 4 days. Finally, the light was brought back on and I noticed my internet was no longer connecting anymore. I later found out that the modem is at fault. It only blinks a red light for a second and then goes off. None of the light at the front of the modem is on.  I have always used a surge protector with the modem. I also tried factory reset (at the back) and that did not work.  I am currently unemployed due to covid, so this unexpected modem replacement bill will be a big burden for me.  I need my wifi to do school work and apply for jobs. Please, If anyone know how i can fix it, i will appreciate it.
