This morning I came into work after the holiday break and my internet would not work. My IP phone was working fine…which it s switch connected to my computer, but no internet there.
Here are the steps I took to figure out my “unknown network” issue:
I started with running the command prompt and then ipconfig /all. It turns out that I was not getting an IP address assigned automatically. So I tried this step:
ipconfig /renew
This did nothing.
Next I tried turning off DHCP and putting in a static IP. It took a while to find/figure out settings, but I finally dissected our network and figured out our Subnet Mask, Default Gateway and DNS server’s IP addresses.
Overall this seemed to do nothing, but then again, I did not try restarting my computer yet.
On our DHCP Server, I reserved an address for my computer specifically.
For this, I needed the Mac Address (Physical address under ipconfig/all)
Then I ran this: win key, type devmgmt.msc, hit enter.
Under network controllers, I uninstalled the driver, then rebooted. (when booting, the network adapter driver will automatically reinstall)
The computer automatically went back to DHCP and grabbed my prefered IP address (the one I had set up in our DHCP Server.)
Problem Solved.
