Only have ping reply after reboot then quits?¿

[quell]

I have a small 3 pc LAN at my house all connected with a 24 port 3com super stack II dual speed hub 500 all with xp. I cannot get the pc's to see each other but they can all access the internet fine. I set up a constant ping on all pc’s to ping each other. When I restart any one of the pc’s I will get about 10-15 ping replies on the other 2 then the ping stops when the pc is completely rebooted (ready to go). I’m not for sure what would allow the ping to start then stop the only common thing is that switch.

I've tried giving each pc a static and dynamic ip but still nothing. I've tried running the network wizard. I tried replacing the 3com hub with a linksys and all pc's can ping the linksys but not each other. I connected 2 pc's directly together with a crossover cable and they can ping each other perfectly. I'm out of ideas. Please any help would be very much appreciated.
Thank you

Do an ipconfig /all on two of the machines and post the results here.

When you say you tried dynamic IPs, what was assigning the IP addresses? The modem? ICS?

Though on its face, it sounds as if when TCP/IP is initialized the pings go through, and when something later, like a firewall, is initialized they stop. Could you describe any Firewalls in place?

As far as firewalls the only one i have is a rg (thing the wireless antenna connects to, wireless isp controls it) which is a dhcp server and thats connected to the 3com hub. I also have a wireless access point connected to the 3com hub. I have 3 pc's 2 are connected to the 3com via rj45 cable. One uses a wireless network card to access the access point. There is no software in the 3com to configure. Its a dummy hub. All pc's have the xp firewall disabled. All pc's are part of the same workgroup. I will post the ipconfig /all later on today when I go home and mess with it some more.

Your DHCP server may be handing out WAN IPs.
You will need to add a router to this mix to get LAN connectivity.

The router would be the only connection to the "rg".
It would provide LAN IPs, and forward WAN requests to the "rg."
You would connect your current machines to the LAN ports of the router, as well as connect the AP to the router.

Or you could simplify life and get a wireless router with 4 LAN ports.

eBay your access point and Hub.

quell, have you resolved this? I've got the same situation.

Thanks,

Unfortunately no I have not resolved this issue. I have checked the DHCP server and it hands out the correct IP address. I have tried what bcastner has recommended but still get the same results. I tried using a linksys router but no luck. If I replaced the hub and the 2 pc’s can ping each other when connected directly to each other via a xover cable, then only thing I can think of that is left is something in the wiring. But I can access the internet fine. I'm still messing with it, so I will let you know when I come up with something.

As a quick test for me. Go into the linksys setup and set the IP of the Linksys router to 192.168.2.1

Reboot your workstations to pull new local IPs from the linksys and try it again.

Note: this is the LAN IP of the router, leave the first page setting for the WAN connection to obtain an IP automaticly.
