Ok. Verified my ethernet on the Empeg works. Now I want to make it wirless.

I have the Apple Airport. And a Lucent Wavelan card.

What IP does the Empeg need to be?

Someone said the Airport will work for this right out of the box, no reconfiguring.

What settings does the WaveLan card need to be?

My setup is as follows:
3 computers
10/100 hub connecting these
my main computer has a 56k modem
a secondary computer has the WaveLan card
All computer surf the internet with All Aboard software
All computers have static IP's 192.168.x.y
The WaveLan card is set to 'ANY' on network name
& get a 10.0.1.x number from the Airport
The Wavelan software shows they see each other.

Now, from which computer(s) can I run and use Emplode?
I would like to be able to use two. The main machine and the one with the WaveLan card.

With the Airport connected to the Empeg(should the link light on the Empeg be on, it isn't), Emplode cannot see the Empeg from either machine. I have tried all the setting I can think of.

All I can say at this point is HELP!!!
I have tried

If the link light isn't on, then that's the root of your problem. I know nothing about configuring wireless networks, but I know a bit about hooking up ethernet.

This connection either needs a crossover cable or a non-crossover cable, I don't know which. If one type doesn't work, then try the other type.

There is also the possibility that there's some kind of hardware problem, such as a bad cable or a damaged jack (perhaps caused by trying to insert a modem plug into an ethernet jack, I've had people do that in my company).

But as far as I know, that link light should light up when you plug it in, or there's no communication happening on the ethernet port. You get the link light when you plug it into your LAN, right?

Yes, I get a link light when I plug to a regular hub.

Yes, I am plugging into the right port on the Airport.

Yes, I have tried many cable to make sure it was not a bad cable.

No, I did not try a (backwards) cable.

Anybody who has the airport working, what cable are you using? Standard Cat-5 or cross-wired(backwards)?

What about if you plug the airport into the hub? Do you get a link light on the hub in that case? (i.e., verify that the airport is working and produces a link light on a device other than the empeg.)

Yes, if I hook the Airport to a hub, I get a link light.
If I hook the Empeg to a hub I get a link light on both units.
If I hook the Empeg to the Airport I don't.

Yup, sounds like you just need a crossover cable.

Is this what others did? Just seems that it would have been mentioned somewhere. Never made a crossover cable. any good spot to check out for correct wiring diagram.

ok. Right now I use the SMC for my laptop and it uses a straight cable. Im thinking if it connects to your hub using a regular port ( NOT AN UPLINK ) then you probably need a regular cable. Are you connecting it to your empeg in the car or using it indoors? Also, is the empeg on when you get no light? Just my thought, but who know if they really matter :)


Also to get a good diagram of a crossover cable I normally goto linksys.com and look for the wiring a lan section!

Not using the uplink port at any time so far.

I am in the house, but trying to simulate what it will be when in the car. With out having to run back an forth. It's cold outside.

Yes the Empeg is on when I get no light.

That's no right (I'm about 90% sure). If it works through a hub and not using an uplink port, then you would need a cross over cable. Anytime you're hooking up two network devices that you normally have to use a hub, and you're not using a hub, you need a cross over cable.

Computer - Hub - Computer would use a straight cable
computer - computer would use a cross over cable.

He almost certainly needs a cross over cable. Every wireless bridge I have used required a cross over cable if it was hooked directly to a NIC.

Link light problem solved. Scoco is right. A crossover cable is required. I made one real quick like, I apparently got it correct. The light now comes on. Off to see if I can link up now.

Still no luck though. Should I be using peer-to-peer(Ad-Hoc) mode? I tried that to and no go.

What do yall think now.?

No, you want BSS (peer to access point mode). The airport is the access point and the wavelan card is a client of it.

ya, when hooking up two devices that normally work through a hub, you do need a cross over cable.. just wanted to make sure.

A crossover cable is required. I made one real quick like, I apparently got it correct. The light now comes on. Still no luck though.

Being a network administrator, I highly recommend against making your own cables. There are issues with the connector types and crimpers that most beginners don't know about. There are also issues with getting the wire pairs arranged properly to prevent crosstalk. It's not as simple as wiring a telephone cord, even though it looks like the same connector with a few extra wires. If you don't do it just right, you can possibly create a cable that seems to work, but it causes all sorts of strange hard-to-diagnose problems later on down the road. It's much easier just to buy pre-made cables.

So, just because you get a link-light doesn't mean the cable you created is good. If you still have trouble, I'd recommend buying a pre-made crossover cable before going much farther.

I found this pic on the net. It takes all the guess work out. So I thought I would post it.

When routing network cable through your car you may not have much choice - RJ45 connectors can be hard to push through small holes in trim!

So long as you have the right crimp tool it's not too much of a black art (but yes, I've crimped LOTS of cables incorrectly through lack of concentration).

It's not so much the crimp tool, it's making sure you use the right kind of RJ45 connector depending on which type of cable cores you have (solid or stranded).

If you use a connector designed for stranded wire on a solid-core wire, it will seem to work for a while, until later, when you start to get intermittent failures that are very hard to trace.

Does anyone actually use stranded cable?
