DHCP Server not connecting after Xbox update

UPDATE

1.- The wifi fix I found doesn't always work.

2.- Sometimes, if the Xbox is on it will connect to the internet after some time (ethernet).

What model of the Xbox console do you have?

Go to your console's network settings and reset to factory default.

Clear the system cache and reboot.

Now try connect your console to the network and let us know if it can obtain an IP from the DHCP server. If not, take the same ethernet cable and connect it to your roommates console and let us know if your friends console can obtain an IP from the DHCP
server.

I am also experiencing this issue. It began after a major software update on the Xbox earlier this year. This issue affects only the XBox, all other devices on the network are fine.

- On powerup: the XBox is able to negotiate an IP address using DHCP.

- After a period of time (presumably the DHCP TTL period): network connectivity is lost and the XBox reports that DHCP is failing.

- Disabling and Re-enabling the network interface within the XBox settings menu restores connectivity.

I have now configured a static IP address on the XBox and it has performed flawlessly since.

I believe that an issue with DHCP negotiation was introduced with the software update that occurred earlier this year.

Xbox now using wired connection and now message says cannot connect to your dhcp server ??????

Did this happen right after an update and are u in the preview program? Yesterday in the middle of a game my xbox shut down and then when i powered up it did an update and now when i tru and connecr to live i get a messge saying “Can’t connect to your DHCP
server”. Ive tried everything i can find, but have had no luck.

Your Xbox should receive an DHCP offer from the DHCP server on your wireless router, but I suspect that the only connection between your switch and your wireless router goes into the WAN port of your router, correct? If so, there will be no subsequent traffic
from the DHCP server on your router. Only the initial messages from your console, being a discovery broadcast message, but no response from the DHCP server, being on the wrong interface.
