Cant get wired internet on my ps3

you need to sequential power cycle all the equipment, turn off ps3, turn off router, and turn off modem. then one by one turn it on. start with the modem. and wait for the lights to settle in. then the router. if all the lights had settled in. turn on your ps3 then try to connect again. this should work

With firewall disabled, try setting the ipv4 properties of your connection as follows: ip address:
obtain an ip address automatically.
DNS
Obtain DNS server address automatically
since this is a peer to peer network you have to understand that the two machines are independent of each other so if this is not the settings on your first machine, please duplicate the exact settings of the first machine on the second machine. The hub might be distributing specific requirements from the modem. Hope this helps

some networks tend to be available but the moment you try to connect,it disappears.maybe its just one of those networks that is really unstable.

try using a modem, connecting a ethernet cable to your ps3 and computer, then your internet cable to your computer and modem. it should work after that.

Try swapping the ends of the ethernet cable between your PS3 and the router. Otherwise, try a different ethernet cable. Also check that there are lights on by your ethernet port on the PS3 and the router.

It is likely your internet connection is not working properly.

Unplug your modem, router, PC, and power down your PS3.

Plug in your Modem.
Wait for it to run it's full diagnostics.

Plug in your router and let it do the same.

Power on your computer and let it obtain an IP address.

Then re-try your PS3.

When you hooked up your connection to the PS3, did you reboot your modem and or router before doing so?

This will clear the memory of those two and allows the PS3 to gain its own IP and MAC address. Try this and see if it helps.

maybe the modem set is different from the modem in the lap top in other words maybe you ps3 needs higher and better connection

The ps3 wifi is very finicky --
While the ps3 scans for a hotspot turn the router off then on so the router aquires the ps3.
Goto settings
Goto network settings
Goto network connection, select enable
Goto Internet connection settings just below internet connection-
Push yes when it says you may be disconnected
Select wired or wireless
For wireless use scan or enter manually
Follow on screen instructions.
Once that is set up return to main menu and go to network near the right
Then once in the internet browser press triangle and goto file and enter the internet address you would like visit.
If all else fail use the ethernet cable to attach it to your laptop. Then run network setup on the laptop and add the ps3.

Turn off the PS3, unplug the power to the cable modem, let them sit 5 mins. Plug in the power to the cable modem ONLY, wait for all lights to be on steady except for the activity light Then turn on the PS3 and check the network IP addy.
