I recently bought a second copy of Minecraft for my fiance and I to play together, but since about 1pm this afternoon I have been trying to get his LAN game to show up on my server list/ vice versa to no avail. I tried setting up an online server both through Himachi and the official Minecraft server jar files, both failed. Through Himachi, with both windows firewalls shut off, his computer can ping mine, and mine his, but not locally. I've tried going through every tiny setting I can find for inbound/outbound allowances. After tweaking, instead of the connection timing out, it just tells me the connection was denied/not allowed.

Through the command prompt/powershell, with both firewalls on, he can ping my Windows 7 system, but the connection times out when I try to ping him. I even tried running the game in compatibility mode for windows 7 under admin(which is stupid because they're both running the same Java version of the game so eh?)

And so after almost throwing his new laptop out the Window, I have come here for your mindful assistance.

TLDR; Windows 10 is rude and won't talk to Windows 7.

He can ping you, but you can't ping him ... sounds like you are on different networks. I assume you guys are in the same house, is the laptop connecting through WiFi and the PC Ethernet? Is there more than 1 router in the house?

I assume you both have private IP addresses (ones starting with 192.168 or 10) ... can you list both IP addresses for me?

This guide has a nice explanation of how to open your firewall:

They are both connecting through the same WiFi network. I'll pull up the IPs, sorry for the super delayed response.

My PC running Windows 7's Ip 192.168.1.105

My fiance's laptop on Windows 10's IP is 192.168.1.124

I already went through that entire guide a few times to make sure I didn't miss anything. I even tried just turning the firewalls off. Nothing.

Very odd ... both computers have the same default gateway? 192.168.1.1 or 192.168.1.254 I would assume. (use "ipconfig" at the command prompt to see the default gateway).

With both firewalls off, can you ping each other? If no, is there any other security software running?

Hamachi is a VPN software that allows people to connect to a computer even if it is behind a NAT ... since you are on the same network, you shouldn't need that.

On the laptop (Win 10) ... If you enter "Network Status" in the Cortana/Search bar, it should bring up a new window. At the top, does it identify the network as public or private? If public, click "Change connection properties" and change it to private.

Default gateways are the same(192.168.1.1)
I have Avast running. I shut that off and both firewalls and now it just says 'destination host unreachable' when they try to ping each other. My network is set as private on both.

And 192.168.1.1 is also the source of the WiFi? Any repeaters or extenders? Are you using a guest network? Some routers have a setting that keeps clients from browsing one another (on mine it's called client isolation). If you have the model number of the router, I'd be happy to look over the manual. The error message you are getting is generally a routing problem. Though I am sure you have done it 100 times, you might want to reboot the router and then do "ipconfig /release" and "ipconfig /renew" on the computers. They might get new IP addresses, depending on your setup. You probably also have your phones on the WiFi .. anything else?

I assume you can ping 192.168.1.1 and/or google just fine, but I have found it's bad to assume, so I should ask.

Yep it's the same default gateway, I even tried setting up static IPs. It's my own router. It's the Cisco E1500(kind of old I know, I need to upgrade to triple banding soon). I reset winsock and all those other settings on both computers. Nothing else on the wifi but my tablet and his phone, and I've changed the password just in case. I did read online that someone called Microsoft about this issue and the support tech basically said WIndows 10 can't network with older versions of WIndows. And yeah I can ping other stuff just fine. It's just his laptop is being difficult.

I'm probably just gonna have to suck it up and upgrade to WIndows 10 once I decide to upgrade my PC. Or switch to Linux. Thanks for trying to help though.

There is an issue with windows networking (networking that uses SMB and machines pop up when you pull up network in the file manager), but not with TCP/IP. Windows 10 can still ping Windows 7, XP, Linux, etc and vice versa.

The E1500 is a stout little router. Sure it's only N, but you get 2.4 and 5 GHz bands and IPv6 compatible. For your 4 devices I would keep using it as long as no issues come up.

So, back to the pinging issue (and by extension the connecting issue). Most routers will list all the connected devices. I looked through your user manual real quick, but didn't see the page, but I assume it's there somewhere. Is it listing both of your computers? Here is the thing ... When you try to ping the other computer the router should forward the packets, but it seems like it's not. Something is stopping it. The router does have a firewall, so you should look if any LAN to LAN communication is blocked. In the user manual, I don't see any client isolation, unless one of you is connecting to the guest network and the other to the main ... but I'm pretty sure your not doing that. Have you ever tried pinging the phone or tablet (if you can find the list of connected clients, they should be on the list)? Does that work? Last thing, rather than static IP, I would use DHCP reservations for all your devices. (page 29-30 http://downloads.linksys.com/downloads/userguide/E_Series_UG_E900Rev_3425-01486_Web.pdf) ... remember after doing the reservation on the router, you will need to do "ipconfig /release" and "ipconfig /renew" on the computers.
