Odd Problem Acquiring an IP Address Through Ethernet

Hello,

After having scoured a plethora of forums and threads about this topic, I think I have a fairly unique case.

This is my situation:

I'm currently renting a one person basement suite, and the landlords have Shaw internet provided to us. I have one wired Ethernet connection to the router somewhere upstairs (which I have no access to). I do, however have access to the router settings on my internet browser.

The router they have is the SMC8014WN.

Now onto the problem. Ever since having moved here, I've had to use wireless from the adjacent suite for any internet I'd like to use. They have a separate router that they've bought since the wifi from upstairs doesn't reach us down here.

The wireless has worked great and satisfied most of my needs. However, I've been wanting to plug my desktop directly into the wired ethernet port provided. With no such luck, nothing has worked in regards to using wired ethernet to my desktop. I've tried re-installing network adapter drivers, re-installing windows, and even different ethernet cables. No matter what I do I simply cannot connect to the internet through ethernet. The troubleshooting wizard on Windows 7 simply says I cannot acquire an IP address from the router.

DHCP is enabled, I've made sure of it. I've restarted the router, turned off/on the firewall, and have rebooted it several times with no luck.

The funny thing is, is my Macbook Air can easily connect through ethernet via a thunderbolt adapter with the same cables/wired connection in the wall. This leads me to assume that it's a problem with Windows 7, or my machine.

I decided to try my Xbox 360 as well. Same problem. Cannot connect to the network with it either. I've tried manually changing all the settings to the one's specified by my router. Still, no such luck.

I'm almost about to throw in the towel in regards to this odd problem i'm having. Is there any additional steps I can try to somehow hopefully solve this problem without actually accessing the router or buying a new one?

Thanks for your time.
 
Hey!

This should be pretty straightforward to identify.

Firstly, when doing any of this testing on the wired connection, make sure that you disable wireless so that we don't get a false positive.

Now - for some troubleshooting -
1. Plug desktop into wired ethernet.
2. Open command prompt:
2a. Type 'ipconfig' - do you have an IP/Subnet Mask/Default Gateway?
2b. Type 'ping 4.2.2.2' - what is the output?

Then, repeat with the MacbookAir using your thunderbolt adapter, but instead of typing 'ipconfig', you'll use 'ifconfig'.

This will probably be easiest to diagnose if you just include all of the output. You can paste all of it at http://pastebin.com/ and just share the link here.

 
After having disabled my wireless adapter, and enabling my wired connection, I got this output from CMD.

On my Mac (not sure if this is the correct information or not).

And pinging 4.2.2.2 gave me this.
