Re: Network Discovery and Media Sharing Problems-Lost me as a customer

After spending many, many hours trying and trying,

I think I've found a solution.

  1. Go to Navigation > Firewall > Connections (networks?)
  2. Annotate the ip range for your LAN:
  3. Delete your LAN in the connections (networks?) window
  4. Re-enter your LAN data.
  5. This action will delete your LAN data in the "My Home Network" function.

(sometimes, changing from "Home" to "Office" or vice-versa has the same effect, but sometimes it does not work)

Don't visit the "My Home Network" function!!

"My Home Network", wich is the Mother of All Network Trouble, will be inactive (displaying "Unknown network") until you visit it again.

Re: Network Discovery and Media Sharing Problems-Lost me as a customer

urganda, thank you!

that worked for me (clearing out the network, then re-entering it, as you better describe above).

Thanks so much!


Mcafee, when the trial period ends, not sure I will pay/renew, considering AVG w/ windows firewall instead. This was a sucky way to spend 3 hours to fix this problem, that should not have been a problem.

also, bookmarking this page as I think the problem or others may come back (so, not too confident on this firewall).

Re: Network Discovery and Media Sharing Problems-Lost me as a customer

I'm glad that worked for you, alb-nyc3. I am no more a Mcafee customer. Now I use Avast!, that also has some network troubles (specially with shared internet connection and all other kinds of  internal tunneling and routing), but runs fine on older pcs and is european, so I contribute to my homeland industry.

Re: Network Discovery and Media Sharing Problems-Lost me as a customer

I am having a significant problem getting a Sony Blue Ray Player model BDP-S570 to start server connection "Media Player 11" on my desktop. I am using a wired  network connection able to see Netflix and other services, no issues with networking. The Blue Ray configuration tool continues to imply there is a fire wall setting preventing the server from starting. I have opened ports as documented by Microsoft, see link below, Additionally I have added a setting for  "IPv6"  "fe80::10: to " "Home" to My Network" McAfee without any success. Help please...

Re: Network Discovery and Media Sharing Problems-Lost me as a customer

Even though this thread is 90 days old, I wish to express my complete agreement with the orginal author (dth1971).

I have worked 30 years in the computer industry (20 in networking), and the last 10 with the largest router and switch manufacturer in the world, located only a mile or so from McAfees offices in Silicon Valley. I'm simply appaled with the enormous problems that the McAfee product presents to its end users. The bottom line is that if you have a home network, and wish to connect two or more devices together, you should buy a different firewall.

I believe the reason McAfee is doing nothing to fix these deficiencies is that the vast majority of home users do not share files or media. As a result, they are unaware of the issues. They simply share access to the internet.  Mom and Dad have their laptops, and the kids have theirs.  Each of them accesses the internet in their own way, but they never do anthing more exciting than that.  If they actually did share data or media on the home network, they would be stopped in their tracks as has dth1971 and me.  I am now using the anti-virus capability, period.  I have gone back to the built in Windows firewall.

I'm completely taken aback by the comments posted by Peter (Ex_Brit), who states that he is "none too technical about this". Apparently so, because six devices (licenses) certainly is not the number of devices that would require an enterprise edition of the software.  Enterprises deploy hundreds and/or thousands of devices.  Most of the people I know here in Silicon Valley have 10 to 12 devices in their homes.  These include PCs for mom, dad and the kids, plus DVD players that have IP addresses, video projectors that have IP addresses, stereo speakers that have IP addresses, cell phones that have IP addresses, photo frames, security cameras, and lots, lots more.  This is the home networkng mega trend that is part of everyday life for those who have the technical understanding of how to do simple networking.  Having encountered all the same problems dth1971 described, I talked to several of my friends who have real home networks, and guess what.  They don't use McAfee.

I read urganda's post about a work-around and her advice not to touch the "My Home Network" function.  She hasn't posted her results, but they did not work for me, nor did scores of other purmutations I tried, both before and after reading her post.

So, here's the bottom line.  If your home network only shares access to the internet, you won't see the gaping problems.  If you share files, media or anything else, your best and only alternative will be to turn off the McAfee firewall.  Trying to run a home network with McAfee installed is like trying to run a network with no cables and the WiFi turned off. Installing McAfee is the best way I know to prevent any networking from ever occurring.

I said I was not too technical meaning in comparison with Technical Support and you are talking 100's of devices which hardly applies to the home products now does it?

Pete (ex-brit),

I too am a 20 year IT Veteran (VCP, MCSE, 5 Exchange Certs, Citrix CNE, Cisco CNA, 6 Sig. Lean), plus I have 10 years managing McAfee Products in corporate environments.

I find your comments short-sighted and terribly defensive (in denial). Society has gone E-everything in the past 5 years, and the quality of harddrives has sunk to new lows, where 3 month drive failures are common. Therefore shared devices and backups are essential to retaining your life these days.  What is the easiet way to backup a device regularly?  It is a network, and your product is stopping that option built into every router sold in the retail market.

None of McAfee's Corporate products are as flaky as this AV/Firewall.  Sorry to point that out, but my neighbor has chosen poorly and selected your product for one of their "Vista" PC's and it is a nightmare.  I have to go over there and fix it every 3 months.  This product is NOT something I would recommend to my enemies!

BTW: My house has 3 iPads, 2 desktops, 2 laptops, Home Theatre, Allshare, 3 Smartphones, 3 iTouch, 3 Wireless AP's and 3 TV's - that is 21 connected devices that share files daily.  There is no way I'm going with McAfee, because it is a pain to manage and it is a resource pig too.

Thanks for the input, but that thread is mostly two years old. If you would like to open a new thread on this subject, please feel free to do so. For now though the old thread will be locked as there hasn't been anything of substance on it for a while.

Re: Network Discovery and Media Sharing Problems-Lost me as a customer

If you are having problems of Windows media sharing and/or network discovery, please try following steps:

  • Open McAfee SecurityCenter, go to Firewall -> Settings, locate “My Network Connections”;
  • Click on “Add” button, select “IPv6” as IP Address Version, type “fe80::” into Address, type “10” into Prefix, and click on “Save” button;
  • You should now see a rule “fe80::/10” displayed in the list;

You can also enable UDP tracking to improve compatibility to external devices:

  • Open McAfee SecurityCenter, go to Firewall -> Settings, locate “Smart Advice and Advanced Settings”;
  • Check the option "Enable UDP tracking" and click on "Save" button;
