One again to some of you: Sorry about the huge f-up with my last thread.
I'm wondering what hardware I need to plug into an ethernet port, and to broadcast the connection to another piece of hardware, which plugs into another ethernet port, thereby wirelessly extending the connectivity to the internet.
I've tried using the wireless card in a PC, but the target device doesn't see it, so I'm left with trying to use an ethernet cable, however the two devices are far apart. So a cable is out of the question. So I'm thinking how to wirelessly extend the signal to emulate an actual cable going from one device to the other.
Or, for about 1/10th the investment, get a WiFi repeater off ebay. One that is configurable as a repeater, extender, router, or modem. It is possible that they all do that but the ones that most obviously can have three RJ sockets. Just make sure it has a proper power plug for your country, not some crappy free adapter.
I can't comment on your PC problem - other than say amen to reply #3. That said, I imagine the same devices would do just as well as a WiFi card, if the ethernet port is OK, and the cost is about the same - unsurprisingly.
Some wifi routers will support a wireless bridge mode, essentially working in reverse to their normal configuration. I've had success doing that on some older Linksys routers.
Properly set up, the wireless card in the computer should be able to bridge the internet connection, although I've never personally done it.

That does not make sense. Cables are far superior when it comes to distance, because they guide the signal and shield it from interference. On earth of course, when you leave the planet wireless is king.
You could also try Ethernet over power line (EOP) adapters.

Only if you are happy about radiating wideband interference across the HF bands. I would like to see these things outlawed, but sadly, money talks.

And given how 'rigorous' the CE stuff is supposed to be you do wonder what 'methods' were used to ge the things 'approved'.
I got a $25 wifi extender off ebay that has an ethernet port built into it. So I'll be picking up the wifi signal, and plugging it directly into the device that can't see the wifi signal.
I guess you know what you are doing, but I think I mis-read you. What I was talking about was converting an Ethernet-equipped Arduino to WiFi. To do that, you simply plug it into the (suitably configured) extender. I now understand that your PC is fine, but maybe there is a third "device" that is giving you grief.
The third device giving my mom a little grief is a DirecTV box that she wants to stream movies through. It's ridiculous that you can watch a million channels with it, but no on-demand movies, unless you have an internet connection to the box. One would think the satellite dish on the roof would have plenty of bandwidth, and it probably does. Arg.
Ahhh, you've got me there. Clearly not an Arduino problem then, but the abovementioned WiFi repeater may be a convenient way of getting the DirectTV box onto the internet.
