Aug 18, 2016 6:17 PMby BobHarris,Try booting into Safe mode
<http://support.apple.com/kb/ht1564>
It is possible that a 3rd party addition you have installed is interfering with your networking. Safe mode will not load 3rd party additions, so you should be able to quickly see if you can access the network from Safe mode.
Please post the EtreCheck output
<https://discussions.apple.com/docs/DOC-6174> or <http://etrecheck.com>
This will show all the 3rd party additions installed.

Anti-virus software has been known to interfere with networking.
Please read:
How does Mac OS X protect me?
<http://www.thesafemac.com/mmg-builtin/>
And you have ClamXAV (as far as I know it does not intercept networking traffic, so I'm not picking on it for that)
[not loaded] uk.co.markallan.clamxav.freshclam.plist (2013-06-13) [Support]
and of all the anti-virus packages running ClamXAV is one of the less offensive, but generally only gets recommended with some Windows biased organization insists you have an anti-virus without bothering to educate themselves about Macs.

Mac cleaners are also not recommented. Sometimes they clean up things they should not.
While I suggest removing the above items, the more important thing from your perspective is getting network access back. And booting into Safe mode should have disabled all of the above, and if any of it was interfering then in Safe mode you should have been able to access the network, unless of course the Mac cleaner deleted something essential.
Did Carolyn Samit
Try System Preferences > Network then select the configuration on the left click Assist Me > Diagnostics
show anything useful?
Does System Preferences -> Network -> Advanced -> TCP/IP show you have a valid IP address (and not a 169.... self assigned address).
If you change your System Preferences -> Network -> Advanced -> DNS -> [+] address to something like
208.67.222.222
208.67.220.220
Google DNS
8.8.8.8
8.8.4.4
Does that get things working? NOTE: the first DNS server in your Advanced -> DNS list is the most important, as it is always tried first, and then only if it does not respond (like 30 seconds later) is the next in the list tried.
...I disconnected the ethernet cable and used justed the wireless since all my other devices are working fine and i rebooted the router several times no help.
I just want to make sure I understand. Do you have Zero network access? Or did WiFi work, but Ethernet Fail? Your statement can be interpreted either way.
If it was just Ethernet, then check your Ethernet cable. Just last week I had a short Ethernet patch cable that I had been using for years fail. My ISP gives me 75+ megabits/sec and that bit of cable was delivering, until recently when it dropped to under 30Mbits/sec. I eliminated everything until it was just the patch cable that isolated to being at fault. So a stupid cable with no active components can still fail.
Again, if it was just etherent, it could be the ethernet router port (or ethernet switch port) you are plugged into. If a switch that then plugs into the router, it could be the entire switch, or it could be the ethernet cable from the switch to the router, or it could be the router port the switch is plugged into.
Of course if it is zero network connections from both WiFi and Ethernet, then that mostly restricts things to your Mac, or your Router deciding it does not like you

That's correct, it does not intercept, firewall or otherwise interfere with network traffic. It can be setup to monitor browser cache, but that will only reveal issues after the fact.

Aug 20, 2016 2:43 AMby MadMacs0,A couple of McAfee processes have crashed, including StatefulFirewall and VShieldScanManager, which could indicate issue involving that software.
And since you also have ClamXav installed, it would not be a good idea to use it's Sentry feature to watch folders in real time as it's likely to interfere with whatever you have McAfee doing.
