Don’t know why SOCKS, never looked this deep before. Does that suggest a change I should make? Thanks

Adware/malware launch daemons can set SOCKS proxies without user participation.

(SOCKS is an Internet protocol that exchanges network packets between a client and server through a proxy server.)

If you suspect you have installed adware/malware—

Try running this trusted utility https://www.malwarebytes.com/mac/

restarted several times MBP mid 2012 Catalina 10.15 2.9GHz i7 16GB RAM 500GB SSD(24.8 avail) New Spectrum modem Arris TG1682 (power cycled 30sec several times).

Network shows Ethernet and Wi-Fi both green with new password.

Background: Haven't run updates in a couple of months because no room on SSD so we've been dragging photos to the LaCie backup and now have 24.8GB available.

So, I got a Malware Bytes update and ran a scan and quarantined (isn't everybody?) the 5 adware

questions. Then the problems started. Spectrum gave up and let me go get a new modem and phone tech gave up after several reboots. I tried to un-quarantine the adware stuff but didn't help.

No other browsers will connect either (Brave, Opera, Firefox, Chrome, Safari)

Call your ISP— you have to provision a new modem

enter 1.1.1.1 as the URL. If you get the CloudFlare splash page, you have a Domain Name Server (DNS) problem. [ CloudFlare is not part of any solution, it is just dead simple to remember their numerical URL.]

Try restarting in Safe Mode (hold shift at startup) and see if the results are different. It does a five minute disk repair, then demands your username and password, even if you normally auto-login. Screen updates will be wonky and slow, because graphics acceleration is among those NOT loaded.

(Safe mode loads minimal set of Apple-only extensions. if results are different, it's something you added. )

Is your system Time correct within five minutes, and the Time Zone shown in

System Preferences > Date&Time > TimeZone ...

all correct?

Are you using a VPN or proxy server to make the connection to the Internet?

why are you using SOCKS?

what is that supposed to be doing for you?

Network Address Translation (provided by your Router) protects you from arbitrary access for the Internet.

encrypted connections suffice for most uses.

Nobody should be using a Proxy Server unless they know why, or have been told to -- by an IT department that can answer the "why" question for them.

It can keep a lot of things from operating correctly.

Most Users are NOT using SOCKS. If you did not deliberately set it up, you should consider it the equivalent of malware, and take steps to turn it OFF.

It may keep you from being able to get Apple updates, which you said you could not do above.

Reboot the router.

well that's pretty weird.

In Firefox, does it show the lock icon to the left go the URL in the URL-bar?
