macos sierra "Destination Net Unreachable"
Hey guys,
I have a weird problem. I have a Early 2015 Macbook Pro running macOS Sierra 10.12.2. I uninstalled a VPN today and after that uninstall, everything went to pot. Now my Macbook Pro gets an ip address from my router that is valid and everything looks normal. However, it cannot reach the internet. In fact, it cannot even ping the gateway router. In fact, it can't ping anything other than localhost and the ip address it was assigned. Everything else gets a "Destination Net Unreachable".
I have booted into recovery mode and reinstalled macOS Sierra and it still exhibits the same behaviour.
My next step, a drastic one, is to wipe the drive and reinstall clean 10.12.2.
Before I do that, are there any steps I can take?
I've checked the routing tables and they look correct.
I've done several route -n flush[es] and then downed the en0 and then up[ped] it with ifconfig.
I've plugged in a thunderbolt Ethernet adapter and it exhibits the same behaviour.
Strangely, a traceroute to 8.8.8.8 yields this:
traceroute to 8.8.8.8 (8.8.8.8), 64 hops max, 52 byte packets
1 google-public-dns-a.google .com (8.8.8.8) 0.729 ms !N 0.0.69 ms !N 0.042 ms !N
It appears not to go through my gateway router at all?
On this mac (an older Mid 2012 Macbook Air connected to the same network, I get this
traceroute to 8.8.8.8 (8.8.8.8), 64 hops max, 52 byte packets

the netstat -nr shows the same routing table as my Macbook Air.
I've also tried removing the SystemConfiguration folder from /Library and removing most of the airport and network related plist files from /Users/<me>/Library/Prefer ences and finally also doing a reset by booting into safe mode terminal and removing the .AppleSetupDone from /var/db all of which is, as you might have guessed, in vain.
I'm at a loss. I can only guess that something has messed up some file somewhere during the uninstall.
Please and thanks in advance.

Of course not. If I had time machine, this problem would never even have happened :)
I'm backing up the SDD to an external USB3 as we speak.

Im sorry man.. I don't have anything else to offer. Good luck to you.

Thanks for your responses anyway. I ended up doing a clean reinstall and everything works again. I'll make sure to do a Time Capsule so that it never happens again :)

While there was no answer here, Ken's help in troubleshooting was much appreciated.

I have indeed tried this. The ip address and netmask and gateway are all correct for the wifi interface. I had also removed and readded all the interfaces as part of my troubleshooting.
The arp -a does indeed show my router with the correct mac address. It even shows the other computers on my LAN (same subnet anyway).
Pinging anything other than the assigned ip for that MacBook Pro or localhost (127.0.0.1) yields a Destination Net Unreachable.
Interestingly, even sending a file to another mac book via bluetooth also does not work. Something in core networking is apparently messed up.
