Win 10 Anniv. Update (v. 1607) no Internet Connectivity

Hi there -

On 9/25 at 4:00 AM my system, already a Win 10 machine, applied updates bringing it to v 1607, build 14393.187. Since then I have had no internet connectivity - either through wifi or with an Ethernet cable. I rolled back to v. 1511 build 10586.589 but still no connectivity.

In the Network & Sharing Center I see 2 networks - my Ethernet and my wifi, however the access type displays NO INTERNET ACCESS for each. I have rolled back to earlier drivers in the device manager - the device manager indicates that both network adapter is working properly (Realtek RTL8188CE for wifi and Qualcomm Atheros AR8162/8188/8168 PCI-E Fast Internet Controller).

I think the problem resulted in the fact that I had Zoho Assist software installed. I've uninstalled it with Iobit.

I've been trying everything out there.

I've uploaded the wlan report - it looks terrible as a txt file but I couldn't upload the html version. I'd be happy to email it to you.

Thanks so much - I'm not a network person and appreciate everyone's help. I was on the phone with MS for several hours yesterday and it got escalated to Tier 2 but I don't have a lot of confidence in the team out there.

Thanks again.

Update - I have network connectivity back - I went into Control Panel -> Network and Sharing Center -> Wi-Fi Status -> Properties and unchecked every item and started checking them back beginning with Internet Protocol Version 4. The only unchecked item is MS Network Adapter Multiplexor Protocol.

New problem - neither Firefox nor Tor will load. Both start a process in the Task Manager but the app never opens. I've uninstalled using iobit and reinstalled and tried running as admin. No luck. any thoughts?

Thanks for any help you can provide!

Waited a few days and updated to 1607 - this time there were no problems. The one remaining issue is Firefox. It takes about 10 minutes to start - even when I change its priority to high in the Task Mgr. There are always thread (1-3) waiting to finish network I/O.

Any thoughts?


Thanks again!

Try Chrome, which takes about a second or two to start on my 1607.

Hi Matthew -

Thanks for your suggestion.

I have 2 monitors - I use Chrome on 1 and FF on the other - that way I can have each browser open on a different screen. The laptop is under the desk.

It's all very mysterious. I went back to FF v 48 - it works - sometimes it takes 5 minutes to open - it just appears as a background process for about 5 minutes and then jumps up to apps in the Task Manager. FF 49 definitely never opens! And there isn't much out there on it - this started with the Win 10 Anniversary Update (1607) - I was already WIn 10 1511 with no problems.

Thanks again.
