This is happening on both my laptop and my new desktop. (Lenovo W510 and Asus Maximus Formula XII)

If I leave all unused ethernet and wireless adapters in device manager, enabled, but disconnected, my internet is crippled and only certain pages load.

If I disable every unused ethernet and wireless adapter and keep only the adapter in use enabled in device manager, my internet works fine.

This just started in the last few months. I've never had problems like this before with multiple unused adapters.

On my laptop, if I am using Ethernet, I must disable the wifi adapter in the network settings and vice versa.

On my desktop, if I am using the GB ethernet, I must disable the 10GB Ethernet and wireless adapters in network settings for the internet to work properly.

Thanks.
 
Just wondering if you have Comcast as your ISP. I gave up on Comcast's DNS servers about 18 years ago because of problems like this.

Spectrum formally Time Warner

My cable service has been nearly flawless. Consistent speeds of 480ish down and 23ish up (400/20 advertised) and rarely if ever down.

I have no problem with Comcast's physical network throughput or stability, just their DNS servers. I have only had to call Comcast 5 times in the last 20 years, 4 times to let them know I was upgrading my cable modem and have them add the new one to my account.

Only 1 time did I need to contact them for a problem, and funnily, it was a DNS problem, but not the typical issues (i.e. not the reason I ditched their DNS servers for being unreliable). It was a reverse IP lookup issue with the IP that I had been assigned, which was causing havok with lots of things (especially anything that would attempt to verify me and communicate back using the IP I was presenting as since the IP and hostname matched fine if you searched by name, but not if the search was by IP). Took about 90 minutes convincing the front line support that it was a real problem and that it was a problem on their end and that they needed to transfer me to their higher tier support (only managed that after sending them my certs as a Oracle Certified Solaris Systems Administrator, my CompTIA Security+, and Linux+ certs to the front line manager at which point they finally believed that I might know what I was talking about...).
