If you're getting 169.xxx.x.xxx, that's an automatic private IP. This means your Xbox is not getting anything from the router at all. Is this a router provided by your ISP, or is it one that you own? Have you done anything to change MTU size on the router? Have you tried resetting the router's settings to their factory defaults, then reconfiguring it?

Yes tried it all. It is a router we got with our voice telephone. Oh and Wireless is still working on the 360. MTU size isn't a problem either.

Also adding to my comment, your internet carrier may also only allow so many MAC addresses registered.

Does either your laptop or PC support custom set MAC addresses? If so, you could change the MAC address on one of those and see if they get assigned an IP address.

MAC is normally disabled but I tried it with enabling it and filling in the correct MAC, didn't work.

 

Do you mean your MAC address is preset?  The MAC address cannot be "disabled", it is a crucial piece of information in the IP protocol.  Do you know where the DHCP server is?  Is the your modem a modem/switch or a modem/router?

Filling in the correct MAC on what?  I do not know if you can manually set the MAC address of a 360.

I mean MAC filtering disabled, meaning letting everything true, and I meant the fill in the correct 360 MAC address in the gateway settings. (it's a modem and router in one).

 

(oh and you can change the MAC of the 360 if you wanted)

 

So if it is a router, the problem will be with the routers settings.  Since the a router is a DHCP host, there shouldn't be anything stopping it from handing out IP addresses except for settings.

 

Not entirely true, my PC's are just working fine, but I can't connect my 360's. It's too bad I can't do a ipconfig all on them.

Edit: you can test the connection on your xbox, everytime it fails while trying to get a valid IP adres (sometimes the router gives me 169.xxx.x.xxx, meaning something is wrong with the leasing, but I should have done everything to overcome that problem.)

I know your PC's are working fine, but if you can change one of their MAC addresses to something new, you will see if there is a problem with what the DHCP host settings (not all NIC drivers support manually set MAC addresses).

The 169.x.x.x is what is assigned when nothing is received from the DHCP server (default address).

You can also try setting the MAC address of the 360 to the same as your PC, then unplug your PC and plug in the 360 instead.  This is a way of (hopefully) verifying that your 360 ethernet port isn't broken.

 

also done that.

What router are you using? Is it the Verizon FIOS router?

I give this thread a 9.6.



Thank god for the disable signatures option.

Which one?

So the 360 ethernet port is broken (do you get any appropriate LEDs on the 360 port)? I find it hard to believe that your router is broken, only bad settings?

Are you using the wrong type of cable (patch cable maybe?).  I think its unlikely that should be the problem because most ethernet MAC/PHY's support autonegotiation, but you never know.

And getting 169.xxx.x.xxx at least means there is a link (I already know that though because the 360 verifies there is a connection).

Yes I know nothing should be wrong and it should be working, but it just isn't that's why i'm so frustrated, I'm very glad there are still people who try to help me though.

 



largedarryl on 11 August 2008

I don't mind trying to help, what else is there to do on the internet ;)

The only other possibilities I can think of is a bad CAT5E cable or a setting issue (either 360 side or router side). What type of a router is it (there is a small chance I'll know it)? Could you put any english screenshots up of the DHCP settings page?



Spankey on 12 August 2008

might be a bit late now but have you tried disconnecting your wireless module?
I don't know if the 360 can handle two simultaneous connections, as far as i know it's an either or thing.
Also, dumb question, but have you double checked or tried opening up your subnet mask?

Yeah done that both, 3 people will take there routers with them so I think it eill be good, I just want to find out what the problem is for the next time (thought it is likely I will just buy a new router.



Spectrumglr on 12 August 2008

sorry if i insist but what happens when you disable DHCP client on x360 and set the ip address manually? from the PC can you ping the x360?
