Can't connect to internet

We are getting close, BDAqua.

I safe booted, logged in as the administartor, repaired permissions, copied the root SysConfig folder to the desktop, trashed the original, and, before I rebooted, started up Safari. Safari connected to the Internet no problem in the administrator's login. I connected to a number of pages.

I safe rebooted again, logged in as the user, and I again repaired the permissions from the user login. Still no Internet. In a fit of desperation, I moved all the user permissions to the desktop. Safari connected to the Internet and I was able to load numerous pages.

I have just rebooted out of Safe mode, and sadly, nothing has changed. no Internet. I ran Network Diagnostics again, and the Internet and Server lights were orange. After I had picked the network name, they changed to green and a page loaded in Safari. Then the lights turned red and the Internet connection stopped.

In Network Diagnostics, by cycling through the step where I pick the name of the network and click Continue, the computer will connect to the Internet for 10 to 15 seconds before the red Internet and Server lights come on. Something is knocking the computer off connecting to the Internet. Something that's rest everytime I pick the name of the network.

We're close.

What is your next suggestion?

Thanks a million.

If I start the computer normally, neither the admin login or the user login will connect to the Internet for more than a few to 20 or 30 seconds. On the other hand, if I log in after a safe boot, both will connect, and stay connected, no problem.

I guess it's time for me to research what's turned off with the Safe boot to see what might be corrupt there. Would a reinstal of the OS be in order, or would the corruption get carried over?

The sun is within reach!

Hi BDAqua,

I finally solved the problem. I disabled the extensions that weren't in Safe Boot, but it still wouldn't connect. I reinstalled the OS, but it still wouldn't connect. Tonight, in frustration, I took it to a Genius at an Apple store. He figured it out in two seconds.

It seems that DNSCrypt was blocking the port used to connect to a DNS server and instead was asking the computer to connect to an internal IP address. By enabling DNSCrypt over TCP/443, Internet connection was restored.

He also said he's seen a lot of this happening lately with DNSCrypt, but that the solution was relatively unknown in the community.

Thank you for all your time, excellent suggestions and encouragement. If I had been smarter and gone staright to a Genius bar, I wouldn't have wasted so much of your time.

If you're ever in Vancouver, I'd love to buy you a coffee, or whatever, for all your help and encouragement.

And, I didn't get burned. 🙂

Thanks, again.
