Connecting 2 PCs without crossover cable


Recommended Posts

Just use the router LOL! No1 here is going to be able to troubleshoot something like this, its just to hard to do over the forum..... You know what your doing apparently and you're there and you can't even do this take..... This is physical task as no lights is a physical issue.

Crossover or not.... Auto-sensing can still fail.... It's not completely fool proof.... I would get a crossover cable or make it yourself.

The fact it worked before might have just be auto-sensing working and now not.

Well on the features for the LNE100TX(v5) 10/100 NIC, it says nothing about supporting auto mdix that I saw.. What are the details of this nforce laptop?? What is the exact model number?

And I'm with offroad here -- just use your freaking router, or buy a $2 crossover cable.

I know for a fact that 1 10/100 NIC and 1 10/100/1000 NIC can auto crossover just fine with a standard patch cable. Just did this the other night to bridge my wifi on my laptop to a desktop that was too far from a network connection. The auto sensing is probably failing which has been documented to happen. It is a shame that it is failing. I would suggest researching on the NIC's to see if you can discover a way to disable it on one of the two and that should help the auto sensing to work.

I don't believe anyone is disputing that fact, completely agree -- only 1 of the cards needs to support auto cross. But the OP seems to be adamant to that they are both only 10/100?? If so I find it unlikely one of them supports auto cross, from the linksys model he gave I saw no mention of it on the features?

But its plain up impossible for it to have worked, if neither of the nics support auto.. So it must be the nforce one.. And yes its quite possible for whatever reason its now failing.

My take so far is -- ok lets forget auto cross feature, just get a crossover cable (a few $)! Or just use the freaking switch portion of his router -- or for that matter just buy a switch to use (couple extra $) for this whatever it is he wants to do that he can not get into?

There not a lot to trouble shoot with auto cross -- it either works or it does not, if not -- I would look to the cable. Or the nic it was running on has failed. He made no mention of changing anything on his drivers, changing is drivers for his nics -- or updating the OSes.. So it has nothing to do with that -- pretty much its a hardware feature of the nics involved and the cable -- he is not getting lights at all.. Then they do not support it, its failed or the cable is bad.

If the nics work with a switch -- then use that ;)

Your Gig nic (or 10/100/1000) autox's, therefore, will work with a standard patch cable. Which is what I stated way back in the beginning. The reason that the Gig nic auto x's is because that is written into the gigabit protocol as a standard. The 10/100 is hit or miss as it is not a standard to have this card capable of autox. Only one card has to be capable of autox as budman stated.

I've never actually needed to use a crossover cable, and I'm 100% sure I don't even have one. I custom built all the cables I have.

Maybe thats the problem. Did you follow the proper color scheme? I don't know how many times I've had coops put together an ethernet cable (even after I showed them how to do it) and just matched the colors end-to-end and think that it would work fine. Well, it won't work fine. You have to couple the negative and positive signals together in the twisted pair or else the fact that the wires are twisted is meaningless.

If they are not correct, you can get very unpredictable results. Sometimes it will work, sometimes it won't work. It will always perform like **** though (<1mbps).
