no recovery with CMD -r

Try connecting the laptop directly to your router using an Ethernet cable which will bypass any possible WiFi issues. An ethernet connection should be more reliable and usually faster.

If you have access to another Mac, then you can create a bootable macOS USB drive.

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 -2002f]

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.

The higher the number, the more obscure the problem.

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

Older Macs may not have a recovery partition. How old is yours?
