This can be caused by a bad WiFi chip, software issues or a setting issue.
In most cases (especially with modern AC/AX routers) it’s a network security configuration issue - a lot of modern routers bias towards WPA3 over WPA2 so this stuff will continue to happen -- the wireless hardware Sony used doesn't see WPA3. This issue leaves you with a choice:
- Bad option (please, please avoid if possible): Powerline Ethernet. The reason I despise this option is unless you *need* to reach for these things there are better options. Powerline Ethernet is only as good as your house wiring; it's the Konami code of networking because if you’re dealing with vintage 20+-year-old contractor-grade Romex, it’s gonna reflect the quality of contractor-grade Romex. I get it - going into your attic or basement isn’t fun, but a good Cat7 wall run is way better in the long term.
- Basic (reduced security): Systemwide WPA2-AES downgrade (AES>PSK if possible for security with less of a compromise -- how you set this varies per router, so look into it based on your specific router.
- NOTE: Expect your ISP to give you a hard time under the guise of “security” (especially if it’s one of those app-managed ones they are now using, like the Spectrum AC routers), especially if you cannot change it on the admin side. IT CAN be done, but they may lie or deny it can be done so push back as needed. I have had to push back against this stuff and cite things like my A+ cert to get them to listen before. This tradeoff is fine because realistically WPA3 isn't a major security bump, but it's not something you SHOULD DO unless there's a legitimate need.
- Intermediate (secondary compromised, but main secured): If you can setup a secondary router with WPA2-AES (Again, PSK IS discouraged but so be it if all else fails; it's not as bad here) but on your normal network. These will coexist if set as a repeater and the ISPs cannot touch you for this, but it requires a capable router (ASUSWRT, DD-WRT or stock FW with the option required; likely needs DD-WRT or ASUSWRT).
- Advanced (requires enterprise or business class gear from eBay, FB Marketplace, or your preferred source of enterprise surplus): Setup 2 VLANs: VLAN 1 (main), and VLAN 2 (quarantined). NOTE: SOME prosumer routers support this, but you usually need a “managed” switch (Cisco, HPE, Aruba, Juniper or L2/L2+ TP-Link) or a capable “Smart Web” switch (Ex: TP-Link DE/PE/MPE). You want to set this up as a quarantined network for your PS3 and other devices as needed; do not add things that do not need it. This is the fastest way; no need to tell ISPs off and it keeps your main network untouched. Essentially you just built a homelab here since you have to use enterprise-level equipment or good business class; this is CHEAP BUT you have to manage it yourself.
If it’s not the network, start with resetting the PS3 back to factory settings, and pray. You may even need to format the PS3, so backup the console first. If it doesn’t fix that way, the WiFi chip is bad.

Did anybody ever figure this out? I have the same problem. Took it down to a repair shop and everything connected just fine. But at home my WiFi and network cable don’t work.

See if you could buy a 2.5ghz router and hard wire it to your main router, then try connecting it

PS3 Does not recognize 5GHz. On Mobile Hotspot switch phone temporarily to 2.4 GHz and you should get a connection.
