Formatted all partitions, including recovery, and Macintosh HD - Data

I was having some general issues with my OS ( Big Sur 11.3.1 ) and had a partition of Windows installed that I never used. So I decided it may be a good time to format my partitions and reinstall with the latest mac os. I may have gone a little over board and formatted everything including the recovery partition and my Macintosh HD - Data.

After everything was formatted, I rebooted the machine and was taken to the Globe for Internet Recovery, I selected my wireless network from the drop down, and waited about 20 - 30 minutes for the progress bar to complete. Once it completed, it displayed the globe with an error triangle over it, and displayed the support.apple.com url with the error code -1008F.

I tried retrying the internet recovery steps a few additional times with the same resulting error. So I went ahead and created a bootable usb with the latest mac os ( 11.4 ), turned off my system, plugged in the usb, powered it up holding down the option key, selected the bootable usb drive from the list of available drives and hit enter. After a black screen for a couple of seconds, it jumps directly back to the internet recovery globe which fails with the same error every time.

I have gone through the steps multiple times to reset my NVRAM and SMC which has not helped. I have also tried creating an additional bootable usb with ubuntu to see if I could boot into that with no luck. I have also allowed the power to drain completely before starting it back up.

Somewhat strange is that the windows bootable partition still shows up when holding down the option key on boot, even after resetting NVRAM and SMC, but of course it does not work as it has been formatted.

I am at a bit of a loss at what to do next. The system seemed totally fine before my formatting misadventures so I don't believe it is a hardware issue. I am not sure if I possibly formatted the hard drive incorrectly, and if so, without Disk Utility, if there is a way to reformat the drive using an external drive or secondary system.

Any help would be greatly appreciated! Please let me know if any additional information is neeeded.

Internet recovery as well. Internet recovery eventually fails giving a -1008F error.

-1008F error

In Internet Recovery, these low negative thousands error messages indicate that your provided Wi-Fi Network is inadequate in some fashion, and cannot be used (for this purpose) in its current state.

Common problems include:

Hidden Network-name

required use of a proxy server to get Internet access

required use of a login page to get Internet access

Use of a login server or certificate to get Internet access

Use of PPPoE in the Mac to get Internet access (typically only applies to DSL)

Use of Fixed IP address rather than good old DHCP

Variance of the time by more than five minutes

Failure of Router to provide workable DNS server addresses, or providing 0.0.0.0 [may produce the error]

If you have an Ethernet port, you may in some cases be able to move your Mac close to the Router and connect to the Router using Ethernet.

Also, make certain the Date&Time and Time Zone are correct within 5 minutes.

I'll go ahead and make sure non of those common problems are occurring. I do have a docking station for my macbook pro with an ethernet connection, but I don't see any options to use ethernet and am only given the option to select a wifi connection from Internet Recovery. Is there something I am missing to run Internet Recovery over ethernet wired connection or should it just automatically start if it is connected via ethernet?
