@Sunshine   Hello and good afternoon, today I was trying to update my router's firmware but I can't seem to update the firmware, so I searched on the internet and found this thread. I am attaching a screenshot of the firmware version and hardware. I have already tried from your website but none of the firmware versions seem to work. My ISP was updated correctly. Thank you and I hope you can answer me.
