Question Hub problem
I am connected to a LAN network for sharing internet. I want to extend my connection to another computer in my room so i buy a new hub. The problem is when i connect my two home computers to my hub. There's only sending signal(no receiving). I think my cabling is correct. And from my hub which connects my two home computers to another hub also has the same problem. From hub to hub, it should be cross-over cable and from PC-Hub, it should be normal cabling, right?

Can anyone help me? Or do i have any mistake?

Normally you will use standard non-crossover cables. Run a cable from any port on the 1st hub and connect to the uplink port on the 2nd hub. If the hubs are autosensing there won't be an uplink port, just plug into any port if that's the case.

If there is not a "uplink" port then you have to use a crossover to go hub to hub. A uplink does the crossover for you so all you have to use is a regular patch cable [straight thru].

If you are creating your own cables get and use the standard diagram for patch cables/crossover cables. if you don't follow the standard you can have mismatched pairs that don't negate the crosstalk/ect.

Thanks u! Now I want to make the connection between my two home pc works first. But the problem is that Both of them can't see each other. Both of them just keep sending packet out bong can't receive any packet.

How can i solve this problem? Anything wrong with the hub or my computer configuration? Both PC use winXP Professional

I'm not sure, but possibly the hub is faulty. At the moment you have two hubs connected via a cross-over cable (which is plugged into normal ports on both). Try removing each hub in turn and seeing if you can receive. If you can, then there's something wrong with the other hub or you've got them connected wrongly.

Some things to test your equipment:

Can you test the cables somewhere else, or try cables which you know are definitely working?

Is there any chance you could try your computers with a completely separate hub?

Can you test the hub in another network which works, and see if it still works with your hub?
