Unable to contact DHCP server

[Osteoporozis]

I've been having numerous problems with the internet provided by my landlord and I've sent in so many complaints that I'm thinking their tech guy has started ignoring me. I'd have called already but I want to be absolutely sure it's not on my end before I point fingers at the cruddy network.

Lately my issue has been that if my computer is off during the hours of roughly 6-9pm it doesn't seem to be assigned an IP by the router and isn't able to connect to the internet. If I'm at home and the computer is on, this never happens and the connection is totally fine, but if the computer is off it's unable to connect for thirty minutes to several hours afterwards.

I've tried every combination of restarting the computer and unplugging my cable from the wall and computer (and by that I mean doing it in every order imaginable) and routinely try ipconfig /release + renew. None of this seems to help until a certain point when /renew just suddenly kicks things into gear and it comes back up. I've saved a log in which, eventually, I'm assigned an IP and /renew works:

Interestingly enough when I plug my laptop into the same cable while the internet is down on my desktop there's no issue; leaving the desktop unplugged while I'm gone has no effect. I'm pretty clueless on this one, and none of my research has yielded any results - most of the threads I've found about this error message are solved by getting new cables and uninstalling McAfee. Sorry for the lengthy post, and thanks in advance for any advice.

If it says MEDIA DISCONNECTED it means your NIC is not seeing the switch port on the other end as if cable unplugged.

Try going into the NIC's property (Power Management):

DISABLE allow machine to turn off this adapter to save power
ENABLE adapter to wake computer
ENABLE WOL only.

When you turn off machine, the little LED next to the RJ45 should remain lit.


If the laptop works, it's not the landlord's fault, not directly anyways.

Oh, nevermind those - one of those is for a VPN and I forget what the other is. "Ethernet 2" is the one experiencing the problem, you can see where it says "An address has not yet been associated with the network endpoint."

Do you know any of your neighbors? I would ask them if they are having a similar problem or not. If they are it means the problem is on the server/router/firewall end of things. If they say no it could mean something is up with your desktop.

A question about the laptop is it connected to your wifi or does it only use a lan connection like your desktop? If it does use the wifi try turning the wifi off or just shut the laptop down during the time period you specified and see if the same problem happens to it. My thought being if its on wifi all day it may have received the updated IP information so it will continue work when you plug it into your desktops lan cable, while your desktop being turned off didn't.
