My MacBookPro15 has displayed a -1006F error

I have a very old MacBook Pro that my friend gave to me with most of it's storage used, and I decided to remove all the data because It was useless to me (I booted using ctrl R). I now want to make a clean reinstalment of it but if I boot in normally it flashes a folder icon and if if boot using ctrl R, it asks me to use the wifi recovery mode. I select my wifi ssid but when I go to the page with the password input, it gives me an error. The error looks a lot like the -1005F(discussed on an other forum) error but says -1006F

Please help as soon as possible, Thank you.


MacBook Pro 15″, OS X 10.11

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.


If your battery was completely depleted, the Date&Time could have reverted to the default, which will not work. There is a terminal command to reset to current Internet Date&Time -- post back for assistance.

If your Mac starts up to error -1008F
