Surface Pro 7 WiFi says "Connected, no internet" when internet is working

I tried uninstalling the drivers and rebooting and the wi-fi is still bad. I hadn't realized that it's not just cutting out completely, it's also spotty, as I discovered during a video call this afternoon. 

All the many wi-fi devices in the house are all connected this router without issue. I hope there's no need to replace it. 

I tried uninstalling the driver and restarting, and it's still not working. I can see that the driver installed is now 21.40.1.3. Windows Update says it's the best version, but at the link you sent there is a newer version, 21.40.2, so I'm going to try installing that next. I'll post an update when I can see whether it works. Thanks!

If this happens again, go into device manager and uninstall but do not delete

the Intel WiFi network adapter and restart. Then reconnect and see what happens.

There are other steps you can try as shown in

https://support.microsoft.com/en-us/help/10741/windows-fix-network-connection-issues

but try the uninstall first. (If it were me, if that failed, I'd go looking for

newer drivers - see below).

Again, the Intel WiFi driver is new to Surface, so this is a brave new world. I

have seen connectivity complaints about that specific Comcast gateway in the

past.

I don't know what driver version is shown for the Intel WiFi in device manager, but you can install the MSI package from to be sure they are installed correctly.

Mod edit: We don't recommend installing drivers that have not been tested on these devices and published by Microsoft in Windows Update.

OK, now I installed some updates. (I may have been mistaken about previously installing updates, it installed a lot of updates this time.)

The computer restarted and came back to "connected, no internet". 

I opened CMD and ran ipconfig /renew and got this: 

No operation can be performed on Local Area Connection* 1 while it has its media disconnected.

No operation can be performed on Local Area Connection* 2 while it has its media disconnected.

After it hung for 2 minutes, I turned wi-fi off and on and and then I got this: 

An error occurred while renewing interface Wi-Fi : The operation was canceled by the user.

No operation can be performed on Bluetooth Network Connection while it has its media disconnected.

Then I restarted the router. After taking a while to connect (about a minute) I'm on the internet again.

I have a fairly recent Comcast router: CGM4140COM

I restarted the router and the wifi and internet connected. This has happened three times. I'll try ipconfig /renew next time, assuming it happens again. 

I ran one update since getting this computer a few days ago, but it looks like there are more updates now, so I'm running it again. Maybe it will fix the problem! 

I'll try to follow up. Thanks!

The Intel WiFi in the SP7 is new territory for most of us. This is the first report. May I ask what router you are using? 

Did you install all the available updates?

If you open a cmd prompt and run the following, is the issue cleared or not?

ipconfig /renew
