Ive recently purchased a macbook pro 2016, It had sierra installed but the wifi was not working correctly so I fully reset the computer. Now i can’t reinstall mac osx through internet recovery because i can’t connect to the internet. Is there any way i can reinstall without internet?

Only other was is to have someone that can run 10.12 make bootable USB Drive with the Sierra installer on it...

Open Terminal (Applications/ Utilities) now copy and paste this command into the Terminal window,
sudo plutil -replace CFBundleShortVersionString -string "12.6.03" /Applications/Install\ macOS\ Sierra.app/Contents/Info.plist
press return
enter your password
press return
Now paste in the createinstallmedia command for Sierra where MyVolume can be replaced with the name of your USB stick
If your USB name has more than one word separated by spaces you would need to type it in as
/The\ USB\ Name
sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Sierra.app
press return
follow the prompts
Can you connect to your Modem or Router with Ethernet cable?
Ok thank you, do you think a new wifi card would work to fix the wifi issue?
