A week ago I started having this problem that whenever I turn on my pc all my startup programs that require internet connection fail to connect(steam, discord,cloud, anything that requires a connection) I usually have to wait from 1 to a maximum of 5 minutes for my network to respond, if I open my browser I get a DNS lookup fail, even after "regaining" my network whenever I open a site for the first time I always get the dns lookup fail, and have to wait a few seconds for it to respond and actually connect while sometimes It doesn't fully connect so I have to refresh every site a couple of times in order for it to be fully loaded.

All of this doesn't happens as long as I'm connected to a VPN, whenever I connect to my vpn everything runs smoothly like it used to work not to long ago, without the need of the vpn (I use tunnel bear and softethervpn); If I disconnect from the vpn every problem listed above starts to happen including the downtime. Forgot to mention this only happens on my pc, every other device I connect works perfectly (reason why my ISP basically told me to find help somewhere else)

I've done every solution I've found on the web and It's the same; (cmd as admin, flushdns, release and renew, google dns on adapter, turning ipv6 off, network reset, restart dns service)

someone halp pls

EDIT: I have win 10 pro

EDIT 2: Sorry I should've mention that I have win 10, I did the nslookup and this is what I got. Microsoft Windows [Version 10.0.15063] (c) 2017 Microsoft Corporation. All rights reserved. C:\WINDOWS\system32>NSLOOKUP server DNS request timed out. timeout was 2 seconds. Server: UnKnown Address: 8.8.8.8 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** Request to UnKnown timed-out C:\WINDOWS\system32>

I did it a second time and I got this: C:\WINDOWS\system32>nslookup server Server: google-public-dns-a.google.com Address: 8.8.8.8 *** google-public-dns-a.google.com can't find server: Non-existent domain C:\WINDOWS\system32>

No, I haven't done anything to my pc, the only thing that happened was that my router was changed, 1 day later after that problems started; but since the problem only happens on my pc my ISP refused to send a technician.

@ xenoid I did 4 pings, one without my vpn (I turned it off a while ago) C:\WINDOWS\system32>ping 8.8.8.8 Pinging 8.8.8.8 with 32 bytes of data: Reply from 8.8.8.8: bytes=32 time=42ms TTL=52 Reply from 8.8.8.8: bytes=32 time=44ms TTL=52 Reply from 8.8.8.8: bytes=32 time=54ms TTL=52 Reply from 8.8.8.8: bytes=32 time=43ms TTL=52 Ping statistics for 8.8.8.8: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 42ms, Maximum = 54ms, Average = 45ms

and right after turning my vpn off C:\WINDOWS\system32>ping 8.8.8.8 Pinging 8.8.8.8 with 32 bytes of data: Reply from 8.8.8.8: bytes=32 time=45ms TTL=52 Reply from 8.8.8.8: bytes=32 time=43ms TTL=52 Reply from 8.8.8.8: bytes=32 time=44ms TTL=52 Reply from 8.8.8.8: bytes=32 time=43ms TTL=52 Ping statistics for 8.8.8.8: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 43ms, Maximum = 45ms, Average = 43ms

@QMord During this time I can connect my vpn and my network would work like nothings wrong, I tried once having the vpn connect on startup and nothing wrong happened, and if i disconnect from it I have to wait for the normal network to "kick in"

  • Very likely the VPN changes the DNS to point to its own and fails to undo these changes when disconnecting. Stating your operating system would help. If you have the nslookup command, in a command prompt, enter nslookup and then server. This is the IP of your current DNS. Give it to Google and see if it belongs to your ISP or to the VPN organization. – xenoid Jul 24 '17 at 20:23

  • Have you reinstalled your network card drivers? Somehow DNS is failing and a faulty network card driver could be the result of that. VPN has its own DNS and all DNS requests are channeled through it. – LPChip Jul 24 '17 at 20:51
  • Can you ping 8.8.8.8 right after closing the VPN? – xenoid Jul 24 '17 at 20:53
