hi, I've got a Windows XP computer with: -Genius LAN GF100TXR Fast Ethernet Network Card (with latest XP driver) -IP address : 192.168.1.1 -Subnet mask: 255.255.255.0 -Device status: This device is working properly. -Net Connection: Enabled And another computer (laptop) with Windows NT 4.0: -Xircom Ethernet 10/100 -IP address : 192.168.50.230 -Subnet mask: 255.255.255.0 -The same workgroup as the WinXP computer. -The leds of both computers are on (connection ok), but it I can't ping them each other. I've tested both computers with anoter W2k computer, the Laptop worked but the WXP again I couldn't ping it. What could be the problem ? TIA Happy holidays!! Bogdan Giusca

to enable your comp to comm each other, you need to have same network number. in this case, try change your windows xp ip to something like 192.168.50.X and try ping the xp from nt or vice versa. if you encounter problem, pls post here again. good luck

Xircom Ethernet 10/100 -IP address : 192.168."1".230 -Subnet mask: 255.255.255.0 -The same workgroup as the WinXP computer. you have the wrong number if you have a cross overs cable, change 50 to 1 if you have a hub, you have to change the number 50 to 2

I had to send a message after reading xck's response. Pete was correct in that the first 3 set's of numbers have to match (so either both pc's have to be set to 192.168.1.xxx or 192.168.50.xxx). xck is totally incorrect in that you have to change the 50 to a 2 if you have a hub or a 1 if it's a crossover. The number has nothing to do with whether it's a crossover connection or using a patch cable and a hub, ABSOLUTELY NOTHING!!! I work for Xerox and deal with networking every day. I don't know where he's learning about his tcp/ip protocol stack rules but that is totally incorrect and I will point you to Microsoft's website which is who created these rules if you like to prove you wrong. The reason the first 3 sets of numbers have to be the same is because you're using a class "C" non-routable ip address scheme (you get this from the 192.168, there is one for each class and class C, according to Microsoft, should be 192.168.100.xxx but nobody follows this standard and they usually go with either 192.168.0.xxx or 192.168.1.xxx (0 allows for more ip addresses total)). They both have to have the same subnet of 255.255.255.0 in order to communicate without a gateway/router. The last number in the subnet can change but that will just limit the number of computers you can have on this subnet so I would leave it at 0. So here is what I would do... Make computer 1 with ip: 192.168.1.1 and subnet: 255.255.255.0 Then make computer 2 with ip: 192.168.1.2 and subnet: 255.255.255.0 Then they should be able to ping each other just fine. Feel free to email if you have any questions.

Andy - I am sure you can answer this ;-) I have the following: windows xp with linksys fast ethernet 10/100 windows 98 with the same Linksys 5 port router and uplink. adsl connection - i think fixed ip address So if I set the TCP/IP protocols as you suggest, does the router have the fixed IP address? and if so where do I set that up - or am I barking up the wrong tree completely!! all the best

John, Yes. If you are sure that your ISP assigns you a fixed ip address then you want to give the router that fixed address. Routers are usually configurable through a web browser interface (it depends on the manufacturer and I think Linksys does do it this way) or special software. The router will have all the necessary configuration parameters just like computers do. The router will actually have a place to enter 2 ip addresses. One is used for the internet connection (your static ip provided by your ISP) and the other for your internal network to allow all of the computers on your network to share the DSL connection. The one used for your internal network you will want to make 192.168.1.1 or 192.168.0.1 (it's up to you but the 192.168.0.1 allows for more ip addresses by borrowing from the other subnet). Then, all of the computers on the network will have to follow the ip scheme of 192.168.1.xxx or 192.168.0.xxx (whichever one you use) and you just want to increase in sequential order to make it easy to remember. So computer1 you want to assign a static ip of 192.168.1.2 and computer2 a static ip of 192.168.1.3 and so on. All devices should have a subnet or network mask of 255.255.255.0. Feel free to email if you have any questions. Andy

i got a linksys for 4 computers networking hub, and how do you get the firewall to be gone and right now the hub isn't going 100% well, it's keep on disconnect from the internet ( cable ) what problem would that be ?? the cable's problem or th hub's? the bug dies many time a day
