DNS Unable to Resolve

Delta3D · 21 Nov 2017 at 22:08

Hi All,

I've recently been encountering an issue with DNS on my Windows 10 Machine.

I'll be browsing the internet fine with no problems and then all of the sudden my connectivity goes pop and whenever I try to browse to a new page I get the generic Google Chrome page saying that the DNS was unable to resolve.

I try firing up a Cmd Prompt window and bash in ipconfig /flushdns however this sometimes works and sometimes doesn't. I'm currently using a Static IP however have tried with Dynamic and received the same. Everyone else on the home broadband is fine including mobiles.

Tried letting Windows automatically select DNS Servers on IPv4 and also tried using googles DNS servers
Primary: 8.8.8.8
Secondary: 8.8.4.4

Also flashed BIOS to the newest version and updated chipset/network drivers to no avail.

Any ideas/suggestions are much appreciated

Hi Quartz,

Local network consists of:
3 PC's running Windows 10
4 Phones (2 Hardly use the WiFi)
2 Laptops (Rarely on)

Running from a BT HomeHub 5.

Here's a bunch of screenshots of the settings

Thanks for the replies,

I've made sure I'm outside of the DHCP range and I'm on a static IP fully. I'll give the nslookup a try when it next happens and also the NBTSTAT -RR.

I also noticed last night when I was watching a stream I lost connection to most things, however the weird thing is I could still send messages over Steam & the live stream I was watching was still giving me content? Skype dropped out and web browsing went with it.

Sometimes I can ping the Home Hub when it goes down but other times I can't - I'll give a try pinging DNS next.

Yeah I meant that I've made sure they're outside by changing it

Now on 192.168.1.20

Ethernet cable is fully plugged in with no damage - Never gets touched/moved

Changed it and got the same issue when I was on Reddit - Seems weird though as streams & steam can still use the internet fine?

99% Sure I shouldn't have any malware - I don't really download stuff at all and things I do download are from trusted sources - also stick to trusted sites, mainly just use Reddit, Facebook and YouTube.

Seems like such a weird issue.

Not sure if PIA VPN Could have anything to do with it - It seemed to happen after I installed that a bit more frequently - It has it's own network adapter however it is set to Disabled when the VPN isn't open/connected.
