Only one system with DNS issues?

[Joe Doe]

I have a six station network in my home, about half LAN, half wireless. All of them have internet except one, who has no internet because the "DNS server is not responding".

It is intermittent and goes in and out (but mostly out). I can reset it by pulling out the wireless adapter stick from the USB port and it will work for a few seconds, then out again. My other systems have no issues, using the same physical stick, put in the same location, etc. I have tried flushing DNS, changing DNS server to google, adjusting placement of router and dongle (even though it's fine with the same dongle and placement on other computers).


What is making the DNS server not respond on only the one computer?

It might be an general problem with the ip configuration. Please tell us way more about the device, like what it is, operating system, static IP or dhcp and so on.

Also try running Malwarebytes for infection.

There's nothing in that post stating it's receiving DHCP requests. This likely means your TCP/IP information has been statically/manually set in network settings.
Go into control panel under network and internet:
Network and Sharing center > Change adapter settings
Right click on the adapter and highlight "Internet Protocol Version 4 (TCP/IPv4)" then select the properties box.
Change to "Obtain an IP address automatically".
Also change "Obtain DNS server address automatically".
Then reboot your pc and test connectivity.

No infections present.

Specs

CPU = i7 6700K
MB = ASUS Z170-AR
RAM = 64GB CORSAIR Crucial "Ballistix" DDR4 2400
GPU = GTX1070 Strix
HDD = RAID 0 (2x) ScanDisk 240G SSD Plus
OS = Win 10 Pro all current updates
Wifi adaptor = Linksys WUSB6300 AC 1200

No static IP, using DHCP, and automatic DNS.

Verified both IP address and DNS already set to automatic.

If you go into device manager, is there any missing devices corresponding to your lan adapter?
I found this in your board's FAQ:

Everything including the Linksys adapter is showing up and running in the Device Manager.

Have you tried a different USB port on the problem computer? Could be that the wireless adapter is making intermittent contact.

 

[SgtScream]

That's a good point. Try using a usb 2.0 port and not a usb 3.0 port.

 

[Joe Doe]

Yeah, I've tried all available different ports. Maddening that it's intermittent as well (mostly off, but will come on for a minute with a reset).

I just plugged in a wired ethernet connection (again) and there were no problems. Then unplugged the wired and went back to wireless, and so far it's kept it's connection. Probably after I say that it will go back to it's DNS problems here pretty soon, hahaha.

I sure do thank you all for the help.

Try this driver:

Try following Linksys's driver installation guide for that driver:

[Joe Doe]

Will try this as well when I can. Otherwise I'm just going to do all the work and route a wired connection through the walls.

Thanks again folks.

If the problem comes back, please open cmd.exe, execute an "ipconfig /all" and post the output here.
