I am trying to reconnect my Magnavox MBP 5120 blu-ray player to my Linksys WRT120N routers wifi (which I have done before without trouble) and I am getting DHCP cannot be acquired. I have change the IP ADDRESS to manual on the blu-ray player without changing the IP address itself and no error. I have checked the routers settings and DHCP is enabled. Is there a way to FIX this? I had it connected just fine so I added the ip/mac address to the DHCP Reservation think that would help it did not. Thia is the player http://www.walmart.com/ip/15080510?www=true&productRedirect=true. and here is proof of the error http://tinypic.com/r/nozwi1/8
From your post it seems it was working and now it does not.
Error messages are not always y ACCURATE. A router will provide DHCP service to any WIRELESS client in range that attempts to make connection.
What did you change?
What did you add or remove?
Wi-Fi devices may fail fora number of reasons.
A. Component failure. The unit has to go back to the factory.
B. Configuration changes. Any body plaything with the device may have changed settings.
C. Severe interference from another device, such as a cell phone at close range.

If it were me, I would take tit to a friend's house and SEE if it works on their system.
But if the device is still in warranty, I would consider sending it back. I did not change anything, did not add/remove anything.
I was just on it conected fine no errors turned the player off and back on and will not connect and gives error
