AC RT-87U sporadically quits

[inPicton]

Am running 380.57. Have been having this issue for several months. Desktop connected via Ethernet. WiFi is also unavailable. When I run the troubleshooting utility, get message: 1 or network protocols are missing on this computer.

Then I run these steps that I found in this article online:

I ran the link to the troubleshooter at end, it couldn't find any issues.

I did not reboot the router during any of the following changes. I wanted to see if making changes at the computer would fix the issue. It did not. Unplugging the router for 15 minutes did fix the issue. However, I expect that it will happen again, as in the past.

Having done all of the steps below, rebooting the computer, did not fix the issue.

I'm sorry that it's so long.

Regards, Paul.

"Windows Cannot Automatically Detect this Networks Proxy Settings" since Windows 10 Upgrade"
OK, so I have been on Windows Answers Chat and have a Ref #....I have spent 2 hours on the phone with my ISP...I have tried all of the offered fixes on all the chat boards and communities (I've been in an Elevated Command prompt so many times it makes my head spin)....I've changed settings and changed them back....I've reset all of my networks and network adapters ad nauseum...and I've used special settings from my ISP to try to bypass the issue.....

Yet, for all of this every computer in the house that has been upgraded to Windows 10 offers the same error message and is so slow or simply won't connect to the internet. I can get to the networks just fine...just can't consistently get to the internet. Even bought a brand new Asus super duper wifi router to no avail.

I am now at a complete loss and wondering what can be done to be able to get to the internet at consistent good speed with Windows 10 and not consistently get the error message above when I troubleshoot. When is Microsoft going to fix this issue. It gets worse with every update. Are there any work arounds that can at least allow me to be productive because right now it isn't good.

Jesinta:

In addition, I have performed the following to no avail:

Method 1

Disable Proxy Connection

I suggest you to disable the proxy connection and check:

1. Click the Gear box at the top right corner in internet explorer.
   
   
2. Click the Tools button, and then click Internet Options.
   
   
3. Click the Connections tab, and then click LAN settings.
   
   
4. Uncheck Use a proxy server for your LAN.
   

Method 2

Resetting TCP/IP and check.

1. Press Windows key + X.
   
   
2. Click on Command Prompt (Admin).
   
   
3. At the command prompt, copy and paste (or type) the following command and then press ENTER:
   netsh int ip reset c:\resetlog.txt
   

Note: If you do not want to specify a directory path for the log file, use the following command:
netsh int ip reset resetlog.txt

4. Reboot the computer and check the issue.

Method 3

Flush your computer's DNS cache.

1. Press Windows key + X.
   
   
2. Click on Command Prompt (Admin).
   
   
3. At the command prompt, type the following commands. Press Enter after each command.
   

ipconfig /flushdns
ipconfig /registerdns
ipconfig /releases
ipconfig /renew

Method 4

Turn off taskoffload to improve network performance. Open an elevated command prompt and type the following commands.

1. Press Windows key + X.
   
   
2. Click on Command Prompt (Admin).
   
   
3. At the command prompt, type the following commands. Press Enter after each command:
   

netsh interface tcp set global rss=disabled

netsh interface tcp set global autotuninglevel=disabled

netsh int ip set global taskoffload=disabled

Again, I ask, when will Microsoft fix this obvious bug in Windows 10 or provide guidance that works?

I now have this problem with Windows 10 and tried all of the above to no avail. Is there any further guidance available?

UPDATE: Following a Windows update this issue seems to have resolved itself in my case, and my internet access and speed is back to normal, however the error is still picked up when I run the troubleshooter.

UDATE 2 - 20 Oct 2015: Still the same issue: internet access very intermittent and error identified as "Windows cannot automatically detect network proxy settings". Having contacted the Microsoft Support Answer Desk online they advised me to run the troubleshooter: http://aka.ms/diag_cssemerg68309

3. Click on LAN Settings.

4. Do the following steps:

• Uncheck the box Use Proxy Server for your LAN.
• Check the box Automatically Detect settings.

In this step, Uncheck both boxes (leave no boxes checked)....problem dating back to Windows 7.

Thanks, John. I'm glad that you included, "leave no boxes unchecked."

I thought that I had it fixed having gone through that long dissertation because all was okay for nearly a week.

I'm wondering, though, why does that make the router shut down?

I have also programmed it to re-boot everyday @ 4:00 am.

Regards, Paul.

Thanks, John. I'm glad that you included, "leave no boxes unchecked."

I hope that's a typo .....should be 'leave no boxes checked' (everything unchecked).

I don't think it makes the router shut down....it just breaks the communication from Windows to the router where Windows is looking for a proxy that it thinks is there, but really isn't. Why the problem can show up all of a sudden, I've never seen an explanation.

When this happens, there is no WiFi available (no signal using a sniffer), nor able to connect to router from another Desktop via Ethernet.

I came across this thread:
http://answers.microsoft.com/en-us/...4b6e-a4e1-b3c8215a0bc0?rtAction=1456183441351

I hope it's fixed, but I'm sceptical...

Will report back.

I appreciate your help!
