I have a small home network with a few computers/tablets and a network-enabled printer, all connected through wifi. The problem is I cannot connect (ping) from one specific computer ("A", 192.168.8.101) to the network printer (192.168.8.25), while at the same time all other computers can. Specifically:
- this seems to be a network/routing problem, as pinging the printer from "A" gives me a "destination host not reachable" error message
- from any other computer/tablet, pinging the printer works, and it is also possible to browse to the printer's built-in webserver and print
- pinging any other computer from "A" works, web connectivity is OK as well
- routing tables ("route print") are identical on "A" and other machines (see below)
- "arp -a" does NOT show the printer's IP-address on "A", but does so on other machines.
I have already tried:
- turning firewall off on "A" (there is no anti-virus software installed)
- adding a static route to the printer
- disabling all other network adapters except the wifi adapter
- adding a static ARP entry using "netsh" command (this results in a "request timed out" error message, rather than "destination host not reachable", when pinging)
- changing the IP address of the printer
- using a static IP address for the printer.
Nothing has helped so far. Computer "A" is the only one running Windows 8.1. I do not know if this affects routing and/or address resolution.
I wonder what I could do next in order to troubleshoot the problem. Are there any settings in the OS that would explain this phenomenon?

After a lot of research on the web, I found a partial solution to the problem. It seems that this particular network printer (HP OfficeJet 8500 pro) does have a problem if there is also a 5 GHz network present. I turned it off on the router, and it suddenly works (I can ping and print from all computers).
However, this does not explain why previously it was only not possible to ping from computer A, but it worked from all other computers. Also, for future reference, I'd like to know how to further troubleshoot this kind of problems... any suggestions are welcome!
1I believe the real problem is that Ethernet adapter Ethernet 3 is taking priority over WiFi and ping is getting lost inside virtual network. You should try to disable Ethernet 3 and try again.
