Networking more than two laptops using cross-over cables.

Hello.

We have 12 laptops that we want to network together (The laptops are running XP). We purchased cross-over cables for this job but then realised that the laptops only have one cross-over socket in the back each meaning we can only link two together at at once. Are there any two into on connectors we could buy and are they relable?

Thank you.

Hi CorrArts,
You will need switches for the job. The cheapest solution is to buy two eight port switches and connect every laptop to them.
Put IPs like 192.168.0.5,192.168.0.6 etc.

Just to check, would this product be suitable?

First, they're called Network Interfaces, or ports.  Second, ideally, they connect to a switch or hub in kind of a star or hub and spoke topology - they're not really intended for A-B only communication, although this can be done.

Also, you'll have to get new cables - you'll need straight through cables, not cross over cables - unless your hub or switch supports an "auto crossover" or "auto-detect" or "auto-mdi/x" ability on all ports.

Worried about phishing attacks?

90% of attacks start with a phish. It’s critical that IT admins and MSSPs have the right security in place to protect their end users from these phishing attacks. Check out our latest feature brief for tips and tricks to keep your employees off a hackers line!

I don't think that is the product that you want to use unless you are in an industrial plant with DC power and fiber optic links.

Something like this:

Or this:
http://www.dlink.com/products/?sec=0&pid=71
They both run on AC power and have enough ports for all 12 laptops to plug into

Thanks lrmoore. Would both of those products work with cross-over cables?

lrmooreCommented:
Yes, the D-link supports "Auto MDI/MDIX Crossover" sensing and will work with either straight or crossover cables
The Linksys does not. It would require new patch cables.

Also would an RJ45 T adaptor in the back of each laptop work or not?

Absolutely not...

Yes, that DLINK switch in the link you posted should work just fine..

Just get a 16 port switch, along the lines of what lrmoore has been talking about. The one you showed is sufficient for the job. We can recommend others, but will only do so if need be. No point in making things more complex.
