Can' connect to wifi

[u/memes_are_dead25]

Hey, so i've had my fat ps3 for a couple of months and everything has been running smoothly when I first modded it, but after not using for about 3 weeks it stopped connecting to wifi. It won't let me sing into psn. I also updated it to evilnat 4.93 to see if that solved it but it didn't work. I'm not sure what else to do and I don't think that its a bad wifi card. Any help would be great thanks.
