can't connect to internet from one mac

[jayhaque]

My Mac connects to my home wifi router. Same as everything else. Everything else is working fine but on this Mac I can't access the internet. Here's what I've tried:

1) check advanced settings -> proxies and there is nothing set for any of the options including https and http

2) manually set DNS server to 1.1.1.1 and 8.8.8.8 and still can't get out to internet

3) turned off advanced protection option on router, still can't get out to internet

4) in a browser, tried to go to https://1.1.1.1 and it doesn't work (it's IP so doesn't require DNS lookup)

5) restarted comptuer

6) tried another account on same computer

7) connect to my hotspot via AT&T and everything works as expected - I can access everything, I can ping 1.1.1.1 and get to https://1.1.1.1, pinging 1.1.1.1 fails on the Mac when connected to wifi

8- one of the first things I did is reset the modem

9) i checked the device list and the unit is not "blocked"

Any ideas what is going on??

Not a Mac person so I can't say exactly how to do these items, but here are a few items to check

1. I assume Mac is connecting to the same wifi SSID as other devices?
2. If you connect Mac to wifi, does it have the same subnet and default gateway as other devices that are connected?
3. Can you ping default gateway?
4. Can you ping other devices on the same subnet?

First, is this a new issue? (That is, has this Mac connected in the past?) If so, what's happened in between the last time it worked and now?

When you connect this Mac to your home WiFi, what IP address does it get? Is it in the same subnet that other devices connecting via WiFi get? Is it an IP address that doesn't conflict with the router's (or another device's) IP address on the WiFi network?

From another device, can you ping the Mac at the IP address it received? (This assumes that the Mac allows ping through its firewall, so it might not be a useful test.) Is the Mac's firewall in stealth mode? (Though that shouldn't keep traffic from going out.)

Trying to ping the router was also suggested earlier. Did that work?

I'm having the same issue after moving apartments (still Fios service). What was the fix that worked??
