Network/Sharing Issues


Recommended Posts

OK, win 7 is installed on a PC which uses a wireless network adapter to access the home network as well as the Internet. Now after a fight, we finally got windows to see the adapter and access the network, but, now for some reason the computer can not see any other computer in the network, but can access the internet, the same is true of the other computers, they can not see the wireless connected PC. Does anyone know a way to correct this?

And how are you wireless connected? Are the other machines plugged into the same router as your wireless? you sure you not on the wireless across the street -- I see this ALL THE TIME!! And would explain why you don't see your other machines ;)

The other issue is if your double natting, do you have 2 routers, or some VOIP device? etc.

What do you mean can not see? Can they not ping it by IP, can they not ping it by name -- or are you talking about network browsing? Is your new windows machine part of a homegroup (default) or a workgroup?

Are you other machines wireless or wired? Many a router supports AP or Client isolation, or sometimes called WLAN partition, etc.. this can keep wireless devices from seeing other wireless devices, etc.

Misconfigured firewalls also come to mind -- there are MANY, MANY reasons your machines might not talk to each other -- with out some details its very difficult to point you in the right direction.

Wireless is to our router :) Only have 1 router, can not see it via network browsing... it does not show up... as for the homegroup it is a part of that... and it does not have a set IP, it is DHCP and shows up in the routers DHCP client list, but is unreachable via ping, as far as the firewall the only one that is installed is the Windows version. The other 4 PC's have no trouble sharing at all, 2 of them are 7, the other 2 are Vista, and they are all wired connections, really seems to me to be a simple solution, but, i can't figure out what that may be!

And our your other 7 machines part of this HOMEGROUP? Or just a workgroup.. If you can not ping it by IP address, then this would point to a firewall config issue.

When you try and ping it by IP from one of your other machines, what does your arp table show after? Try pinging the machines IP, from one of your other machines.. then look at the arp table on the machine you tried to ping from.

example

C:\>arp -a

Interface: 192.168.1.100 --- 0xb

Internet Address Physical Address Type

192.168.1.3 00-09-5b-e2-cc-db dynamic

192.168.1.4 00-0d-56-f0-f0-09 dynamic

192.168.1.50 00-15-99-21-1c-a0 dynamic

192.168.1.99 00-06-dc-43-ad-78 dynamic

192.168.1.101 00-13-20-14-b0-34 dynamic

192.168.1.128 00-1e-2a-d3-c9-3d dynamic

192.168.1.200 00-1f-e1-52-cd-4e dynamic

192.168.1.201 00-14-a5-ff-4a-91 dynamic

192.168.1.252 00-13-10-fe-84-08 dynamic

192.168.1.253 00-50-04-d8-e8-be dynamic

Do you see the Correct MAC for your machines IP? If so -- then yeah it would really point to a firewall blocking ICMP.. if you got all zero's etc.. then you got other problems with your wired machines talking to your wireless, can this machine ping your wired machines?

you can try typing "\\COMPUTERNAME" in internet explorer (or the explorer doesn't really matter) and by computername I mean the network name of the computer you are trying to acces. So for example your pc's network name is budman and one of the pc's your trying to acces is computer01 then you type \\computer01. This made the pc's show up for me (at first I didn't see them in explorer under network, now they do and I can acces them)
