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

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?

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;

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

@csystems: I'm sorry about my solution not working for you. Please pay attention to the fact that you not only need to avoid touching "My Home Network" (older EasyNetwork), but you have to previously delete your EasyNetwork settings by deleting your entire network. This solution does work for me.

@lixiao: I haven't tested your solution yet (since mine works for me), but I found strange using a ipv6 network address for a device which has a working ipv4 network address.

P.S. I will start a topic saying "why I won't renew my subscription", explaining these troubles and new ones I've discovered from time to time.

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

Adding "fe80:: / 10" solved my network sharing problem.

What does it do?    Does it affect my home network security?

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

Some Windows services like UPNP and media sharing might use IPv6 addresses, adding that rule is to allow traffic coming from those IPv6 addresses. If you have a wireless network and it is secured (e.g. strong password and encryption, and/or MAC filtering etc.), this rule is generically considered safe, as it only covers local addresses that can only exist on your local network.

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.
