Wifi issues [Device or resource (DNS server is not responding]
Disclaimer: This is actually my girlfriends' PC that she's been having issues with. I'm unfortunately not able to physically access the PC as she's in another country. This is her post largely but I've added some more technical aspects to it. Thank you.
I have some Internet issues for the last few days and I am just running out of ideas.
First my specs (no idea if you need that all, but better safe than sorry):
Motherboard: MSI H110M Pro-D (MS-7996)
Processor : Intel Core i5-6500 @3.29GHz
Graphics: NVIDIA GeForce GTX 1070
Ram: 16 GB
My Windows is installed on my Samsung SSD 850 EVO.
Ethernet is not an option the only option I have is WiFi, I'm using a PCI wifi card with the Intel Wireless-Ace 9260 Chip. I am also living on the country side and my plan is only 16Mbps to begin with. (higher is not possible where I live) Even though I have quite a limited Internet speed, everything worked fine the last few months. I am playing online games, was even able to stream some games in decent quality. Now a few days back all of a sudden my Internet cut out completely, I assumed it was an issue with my provider, no biggie, and went to bed.
Now the next morning my Internet was still not working on my PC, on my phone everything worked well.
I have tried [regarding the router]:
Restarting it physically
Restarting it through software
Resetting the router to factory
I have tried [regarding my PC]:
Setting a manual DNS server to Google [8.8.8.8 and 8.8.4.4]
Windows Troubleshooter and I got the following message: Your computer appears to be correctly configured, but the device Detected or resource (DNS server) is not responding.
Disabling my firewall and anti virus programs.
Restarting my PC
Flushed DNS, and used Ipconfig through CMD.
Disabling IPV6, all power saving options.
Checking for any viruses with Malwarebytes and Bitdefender.
Whenever I got my Internet back, the first 2-3 minutes it works fine and I get my usual speed back, but then it just drops down again to around 250Kbps MAX! , it's just not usable.
The longest it worked for was roughly 30 minutes after I factory reset the router.
No updates happened before the issue started occurring. I have set my Windows to update only manually and I also haven't installed any new programs. After the issue started I updated my Windows, I am now on Windows 10 Pro Version 1909; Build 18363.815. I updated my WiFi cards driver and am now on the most recent driver.
I have also tried disabling my WiFi card and to use a WiFi USB dongle [802.11ac Wireless LAN Card] instead, I have the same issues there. That's what leads me to the suspicion it would have to do with software issues maybe? Since my phone has no issues connecting with the Internet at all, if I do a speed test on my phone it also shows the best results possible.
What can I do? Does anyone have other ideas?
Thank you in advance for any help with my issues.
