Could really use some help understanding the DNS mechanics which might be at play here.
In a nutshell the big mystery is this: if my VPN to the office is off, everything is sweet like candy as far as my download speeds–near instant on my 400 mb/sec Spectrum connection.
However, if I have the VPN from work up (and am not even RDP’ed into my work PC or anything), then I get a 8-10 sec delay on everything I request from the web on my local PC side, if that makes sense.
So VPN is up but I’m not remoted in to anything. It’s just on.
Then I go to my browser (any of them, doesn’t matter) and I go to some website.
I get 8-10 sec delay for virtually every request and in the bottom left of all the chromium based browsers (Chrome, the new Edge) I get “resolving host” during that time. If it’s Firefox I think it says something else but I still get the delay.
What could be happening here?
I mean, I’m not sure what the various possibilities could be for why my PC’s browser would try to use the VPN (apparently) to resolve http just because the VPN is on and then, apparently, go on out to the web like it would normally, only 8 secs later.
I am using public DNS (Google’s at the moment, configured at both the PC ‘s internet adapter and in the router’s settings).
Also, to save some troubleshooting time, this has been going on since mid last year and I have since replaced almost the entire “supply chain” if you will, including:
- PC – Now on CyberPowerPC
- OS – Windows 10 PRO is current OS
- wiped OS 2x, even on new PC
- uninstalled chrome including after turning off all sync’ing (thought it was just a chrome problem at one point)
Also, this only happens with my PC. My wife has a PC which is hardwired into same router and it does not suffer this way–nor do any of the other 8 or so devices on our network (one other pc and several mobiles/tablets on wifi, TVs etc.)
Not sure what else you might want to know.
My IT team at work is stumped on this so I’m looking for any help or suggestions I can get.
Many thanks in advance. Would love to kill this problem after going at it off and on for almost a year!
Here’s what my basic set-up looks like.
CyberPowerPC to Nighthawk Modem, then out to web and/or VPN
