I dont know if this is the right section to put this in but I had an old router tucked away for some time and decided to connect it to my modem to change my IP address. So I plug in the router and it works fine, except I forgot the username and password to the router login page. I then decided to reset my router, but now every time it turns on the wifi symbol on the router stays on for a split second and turns back off, I've tried multiple things to get it to work but I simply cannot get it to stay on. Any advice helps, thanks!
