No network access for Xbox 360 (Failed IP Address)

Just tried what you suggested but nothing changed; I still have a problem with the IP Address.

I'm not sure setting your IP to the LAN Configuration will work. I would try setting it as the WAN IP and see what happens there.

Furthermore, Check to see which updates were recently installed via Windows Updates, and I would be careful about Auto Updating in the future. WU has been known to cause some issues with peoples gimmicked setups. I know I've had plenty of headaches from it.

If I'm going to be honest, I have no idea how to make changes/settings for either LAN or WAN as I've never had to before.
With regards to Windows Update, all that appear for the recent update were security updates as far as I can tell. (But yeah, I've noticed WU tends to create problems for some settings I've changed before, too.)

To ensure that the point to point ethernet connection between the laptop and xbox are on a different subnet please use the following addresses for the ethernet adapter(s):

XBOX:

IP address: 172.16.1.11

Subnet Mask: 255.255.255.128

NO DEFAULT GATEWAY

LAPTOP:

IP address: 172.16.1.12

Subnet Mask: 255.255.255.128

NO DEFAULT GATEWAY.

For the connection to the internet using the phone hotspot you should be able to change the DNS servers as listed above and test it. That being said I would keep it on Auto assign since a phone hotspot is not a router and has it's own set of configurations.

I take it you mean I should set the IP Address when asked on the Xbox to that you mentioned in the part you entitled 'XBOX:'? If so, I'm not sure what to do with the one for the laptop.
If you're able to edit the IP Address on the laptop (and Subnet Mask, etc.) I honestly have no idea how.
I'm not really one for having to set things up for a network or anything of the sort, so I'm completely clueless.
I'll try the DNS settings like you suggested, though.

Thanks for the help (both of you)!

Yes put the address and subnet mask in the Xbox (ONLY WHEN AN ETHERNET CABLE IS CONNECTED TO THE LAPTOP).

As for changing the IP address for the laptop - DNS Addressing - How to Change in Windows 7

   Warning

Do not change the DNS servers. Follow the above tutorial up to Step 6. On Step 4 make sure you right click the ethernet adapter and NOT the wireless one when selecting the properties. Once the you have TCP/IP properties, click on the 'Use the Following Address' button and only enter the address mentioned in my previous post.

This should allow communication across that ethernet link between your laptop and Xbox. If you wish to connect to the internet then just connect to the wireless hotspot.

   Note

You may need to re-enter the IP address on your Xbox when you wish to connect to the laptop since an Xbox can only use one connection

For some reason, it still doesn't work.
I've got it set up like this on my Xbox:

IP Address: 172.16.1.11
Subnet Mask: 255.255.255.128
Gateway: 192.168.43.1 (It won't let me remove the gateway as even when I erase everything to do it over it reappears, then says that I can't leave it blank.)

For my laptop, I have it set up like this:

(Local Area Connection, Internet Protocol Version 4 (TCP/IPv4) Properties)
Use the following IP address:
IP address: 172.16.1.12
Subnet Mask: 255.255.255.128
Default Gateway: Blank

The DNS server/settings on both my Xbox and laptop have been left alone, so they're blank too.

What do you mean by 'accessing'?
Do you mean how am I connecting them, using them, or..?

And on the Xbox it says 'Enter a gateway address. This address must not be 0.0.0.0, 255.255.255.255, or 127.0.0.1.'

Edit::
Also, just tried pinging the address you told me and I got:
'Request timed out.
Request timed out.
Request timed out.
Request timed out.
