Question about Sony Playstation 3 (PS3) Console

PS3 can't obtain IP address through LAN switch

In my home network, I have an all-in-one linksys cable modem/router/gateway with a built-in 4-port switch. This router/gateway also acts as my DHCP server. When I connect my PS3 to the switch, everything works fine (PS3 is able to obtain an IP address and access the Internet through the gateway). The PS3 Internet Settings are set to automatic (use DHCP). I recently added an external 24-port LAN switch (HP Procurve) with an uplink to the router/gateway. I think I configured the switch (set to the same subnet, use the Linksys as the gateway). I then connected all the computers in the house to the HP switch. They work perfectly (they are able to obtain IP addresses through the Linksys DHCP server and access the Internet). However, the PS3 fails the Internet Test function, saying that it can't obtain an IP address. When I move the connection from the HP switch back to the Linksys switch, it starts working again.

I have not tried manually setting the PS3 IP address, gateway and DNS server. I hope to understand the DHCP issue better before trying workarounds.

Any ideas?

    yes, it is a managed switch (web interface). Procurve 1800 24G. The documentation doesn't mention anything about being a DHCP relay. I found some FAQs and such about DHCP relay function for much larger enterprise-class switches, but nothing for the 1800. The config has the ability to enable or disable DHCP for the purpose of the management interface. It is set to "disabled". I manually set the IP address, subnet mask and gateway.

    It is strange that my pc's have no problem reaching the DHCP server, but the PS3 does.

    Since the Procurve 1800 does not provide a DHCP server itself, you would think it would be able to relay to a second-layer DHCP server.

    Do the PS3 Advanced/Manual Internet Settings offer anything that might help?

    Just to let you know, I've tracked down and fixed the problem. I was looking too deep. It had nothing to do with subtleties of DHCP or cascaded switches. The problem was a bad 110 punch block on port 8 of my patch panel! I moved the wiring to another block and it works great.

    Thanks for your help. You convinced me that what I was doing was right and that the problem must be something really simple.

    You seem to have it all figured out, however could you explain in VERY simple terms (as I have no computer knowledge) on how to fix the DNS 80710102 problem on the PS3. We have a wired connection, we only have 1 port, so the PS3 is the only thing connecting at that time. It finds the IP address but the Internet connection fails. Do you think you can help?

    ok, well, here are my next thoughts.

    the PS3's network settings are kinda primitive, not much to do in there. Unfortunate, but true.

    have you tried disconnecting all the computers (unplug their network cables - some NIC's maintain an active connection even when the computer is shut down for WOL and such) and then plugging only the PS3 into the switch? If DHCP works then, it's something in your switch that's messing with things. If it doesn't, I would be inclined to think that something in the PS3 settings is not on the up-and-up, even though this seems highly unlikely.

    oh, by the way, i don't know if you've seen this, but this guy is having the same problem, only he's in a bit of a tiff because he's on a college network.

    If unplugging the computers doesn't work, I would try setting the switch within the DMZ of the Linksys, if it has this option. Could be the linksys's fault too.

    It is very strange that the PC's are receiving a DHCP address while the PS3 is not.

    If you were to set a static IP, could your computers see the PS3 locally? ie, the PS3 cannot access the internet but media-sharing and other local features are available?

    Lastly, double check any and all options in the ProCurve that have to do with NAT, IP Address translation, DHCP, etc. Make sure the Linksys is handing out an adequate number of IP's as well. Sorry for all the simple suggestions, I hate when tech support does that but just trying to cover all the bases. On-site is a lot easier too :)

  • Anonymous May 11, 2010

    when you say that you configured the switch, i'm assuming you mean that this switch is a managed switch, ie using a network interface. is this correct?

    it sounds like the PS3 is using the first layer device to obtain the DHCP address - the switch isn't handing them out so it won't get one. HP has a few tech bulletins on setting up DHCP relays in ProCurve switches so that a second or third layer device can hand out IP addresses.

    Have you enabled DHCP-relay in the switches management console?

My DHCP is not assigning a dynamic address to one of my seven wired devices. I've had to switch over to a stati

On the second router just plug a port cable in from your main routers port into the wan port and then be sure to change the second routers gateway and IP address to a different number. Say that your main router IP is and for your second router IP you could use or what ever combo you want and then you should be able to use both routers together. Is this what you are trying to do?
Linksys routers as well as all routers with DHCP enabled should be able to handle up to 255 separate IP address's for a LAN network. Is the firmware of the Linksys the latest? If not, down load the latest firmware and flash the router to update it. Or, check out third party firmwares like Tomato to flash that tired Linksys and turn it into a real router.

Turn the DSL modem off.

Turn the Linksys router off.

Turn your computer off.

Check that all the cables are correct & are connected:
* 2-wire or 4-wire cable between telephone wall-port and DSL modem;
* 8-wire cable between DSL modem and the WAN (or 'Internet') port on the router;
* 8-wire cable between one of the LAN ports on the router to the network-port on your computer.

Turn the DSL modem on, and wait until its blinking-lamps settles down to a repeating pattern.

Turn the router on, and wait until its blinking-lamps settles down to a repeating pattern.
Ensure that the lamp for the WAN connection is on.

Turn your computer on, and let it boot.
Ensure that the lamp for one of the LAN ports on the router lights up as the computer is starting.

After your computer has booted, your router should have assigned an IP-address to your computer.
Click Start
Click Run
Type CMD
Press Enter
Press Enter
You should see an IP address like '' for your computer,
and a similar IP-address for your "default gateway".
If you see an IP address like '', then your computer has *NOT* obtained a *valid* IP-address.

Also, your router should have obtained an IP-address from your ISP (AT&T),
and you should have Internet access -- try to access '' (or any other web-site).

How do i hook up my router?

There are several ways to do this, depending on how your network is configured.

Generally, if you have only one router - you connect the network jack of your cable modem or DSL modem to the WAN ("wide area network" or "internet") jack of the router with a CAT 5 network cable or jumper. Each computer's network jack would be connected to one of the router's (4) LAN ("local area network" or "home network") jacks labeled 1, 2, 3, & 4.

In the picture above, the left most jack (WAN) of the router connects to the cable or DSL modem. The "LAN" jacks labeled "1, 2, 3 & 4" connect to each computer's network jack in your home.

The above would change if you are simply adding this router to extend an existing network. You'd likely be using this router as a switch, and leaving the routing duties to the main router. Over simplified, all the CAT 5 network cables would be connected to the 4 LAN jacks. There would be no connection to the router's WAN jack because the output of the first router provides only private IP addresses used in YOUR location. The internet IP address from your ISP is used only at the first router so that your entire home has the single IP address. The WAN jack is for internet addresses only - and the LAN jacks are for local / private addresses in your home only.

Have a look at the LinkSys web site for help configuring your particular model router, or reply with the model and version here.

I hope this helps & good luck. Please rate my reply - thanks!

How can I my up my comcast netgear modems wireless to work? when I try my PS3 it detects a sginal but wont obtain an IP address. The same with my lap top.

You have to change the ipddress on the router different then the modem. For example and leave the modems ip alone. Plug the cable into the Lan port of the router. Go to the setup screen on the router and tell give your username and password that
Comcast gives you. You will need comcast gateway address and dns numbers. There will be a connect button on the router and tell it connect it to the modem. You are trying to let the router receive that only ip address.

Plug the ethernet cable from the modem into the Lan port on the router. Your modem and router are trying to use the same gateway ip address. If you know how to do it change the Lan IP address of the router and plug the modem back into the wan port and it should work..

Cannot share my cable modem connection

You need to connect a router to the cable modem.  The router then gets an IP address from Comcast and provides a gateway between the computers connected to the router.
The modem expects to communicate with a single Ethernet device, and provides an IP address to the first device that provides a piece of data called a MAC address.  By placing a router in-between, the router gets the IP address that lets you communicate on the Internet.  It provides local IP addresses to the equipment connected to the local Ethernet and "routes" those to the Internet.  You can either hook your two devices into the router if it has enough ports, or hook you switch to the router and hook your PC and PS3 into the switch.
