I've got a home network (Verizon Fios). I've got multiple computers and all connect to the internet fine except one. This computer has been connected for years. I'm suspected a hardware problem on the motherboard, but somethings don't add up.
Thinking the motherboard network hardware was failing, i even disabled it in BIOS and installed a brand new PCIe based card, which is recognized, drivers installed, and still gets the same exact error. I've tried resetting the MAC address. I've tried disabling the windows firewall. I've tried disabling the anti-virus (I've got Avast and Malwarebytes)
If I tell it to get it's address from DHCP, I get the generic stupid IP that works for diddly. I can override it and specify the IP, mask and router and then it says ok, you're on the home network, BUT it can't talk to anything else. Using PING I get "general failure" when I do ping. Even to LOCALHOST... (ping localhost)... So I can't even PING myself..
Wierd thing, is I have a XIMEDIA NDAS device (network storage) and THAT drive IS accessible. So the problem seems to be specifically focused on the TCP/IP side, not the Ethernet side (the NDAS uses an ethernet non-IP protocol). The network printer is not reachable either (IP based).
The system with the problem is running Windows 7 64-bit ultimate edition. About the only things that have been updated recently on it are these:
a) I updated Avast anti-virus to the latest version
b) Windows Updated installed MS .NET Framework 4.5.2
c) A few days earlier a version of McAfee anti-virus got installed as a piggy back of a Java or Adobe Flash because I must have not turned-off the freebie, so I had to un-install it.
For history, I've had an intermittent problem with the network adapter disappearing (completely going away) every 2-4 weeks and it would come back if I turned off the computer and unplugged it for a few seconds. Which is why I suspected hardware issue and had a brand new PCIe network card sitting ready to be installed when this whole thing happened.
I'm out of ideas at this point. If I unplug the cable from that computer and plug it in another, the other computer connects fine, so this is not a cable, switch or router issue (i've reset the router, swapped switches, cables, etc, just the same, but it makes no difference).
Out of ideas now.
