I've my PS3 (60GB-model) connected with Wi-fi to my network with ~12Mbps down and ~3.5Mbps. Though all games (GTA Online most recently) keep lagging and I don't think that should be a problem with that speed. I've tried with wired connection and that works much better though I have to use wireless. I've no problem with Wi-fi on other kinds of devices.
Using Pingtest I get 103ms on the PS3 and 36ms on my laptop.
Is there something I can try to fix this?

Wi-Fi is rather notorious for being susceptible to interference (they're just radio waves, after all). Here's a small checklist that you should go through to make sure you're doing everything you can to reduce interference:
If nothing helps, you'll just have to somehow get a wired connection to the PS3. Your other devices probably don't need as little delay that the PS3 online games require to be played with no noticeable problems, hence why you're not experiencing any issues on them.
Quick edit: A difference of 103ms vs 36ms using the same router is pretty big. I don't know if consoles are known to have slightly worse network capabilities, but it also seems like there's some interference, or it might just be that the PS3 is too far away from the router.
