Often, when I am developing something on Android and come back to a windows computer I haven’t used for a while, the emulator won’t connect to the internet.

It will detect the “Android Wifi”, but not the internet. Grrr

I generally do the following;

Manually disable all non-network adapters and loopbacks I may have running on the machine

Go to Network adapters and right-click disable all non-essential adapters

Open up an administrator powershell window using cmder run netstat

netstat -r -n

This will show a list of all the adapters and their routing tables. From this list I pick the actual Wifi adapter and make sure its at position 1 in the interface tables.

e.g.

Interface List
3...10 03 b5 65 30 4e ......Microsoft Wi-Fi Direct Virtual Adapter
10...12 03 b5 65 30 4d ......Microsoft Wi-Fi Direct Virtual Adapter #2
<strong>9...10 03 b5 65 30 4d ......Intel(R) Dual Band Wireless-AC 7265</strong>
1...........................Software Loopback Interface 1
===========================================================================

So, I enter the following to bump the Intel adapter to the first position of the interface table

Set-NetIPInterface –InterfaceIndex "9" –InterfaceMetric "1"

Resulting in the table looking like..

Interface List
<strong>9...10 03 b5 65 30 4d ......Intel(R) Dual Band Wireless-AC 7265</strong>
3...10 03 b5 65 30 4e ......Microsoft Wi-Fi Direct Virtual Adapter
10...12 03 b5 65 30 4d ......Microsoft Wi-Fi Direct Virtual Adapter #2
1...........................Software Loopback Interface 1

Reset the DNS to globally available servers

Open up the network settings for your computers Wifi adapter and use the following DNS settings

8.8.8.8 (<a href="https://developers.google.com/speed/public-dns/">google dns</a>)

208.67.222.222 (<a href="https://use.opendns.com/">OpenDNS</a>)

Flush the DNS

At the powershell window run

ipconfig /flushdns

Restart the Android Emulator

Everything should now connect..
