I was just asking if you thought it was important. I'd say I have my
answer, thanks.

That information helps immensly. Just get a USB adapter then. 15' or
under, it's easy.

I have this one with a 4 dbi omni on it:

And it works well. I put it on a 15 foot extension cable. Not
really any cheaper but simpler (in a way) than a wireless client
adapter.

I said "carry" not "pick up". Confusion is, I was referring to
Powerline networking in general. It can carry signals, it's not a
radio, it's a wire, effectively. Yes, the model you linked is the
one that has an AP built in to the powerline part and I glossed that,
sorry.

I'm just saying Powerline Networking acts as an ethernet cable.

No, they have firmware to act as Access Points not as Clients. I
don't think anybody has hacked them yet, that's all they can do.

Good, should be easy then.

I would not say that. They work fine.

Thanks for the good reply, I will take a look at the links.
Concerning your remark that I might be better off with a usb client
adapter, I have seen many surround a usb device with a home made
parabolic dish reflector. However, there seems to be universal concensus
that usb radios are too weak and cannot match the power of the better
pcmcia cards. I think you stated in an earlier post that this was
related to their integrated antennas? The seattle wireless page on usb
adapter specs seems to have disappeared. That was the only good
comparison I could find and it was not very good, nor complete. Someone
needs to test all these devices as it is hard to find good info on them,
especially relating to receive sensitivity. I might just have to buy a
few at a ok return store and test them to see if any work. I have doing
this as it is time intensive and not very good for either me or the
store.

thanks for the good reply. this usb adapter with external antenna jack
looks good. using my laptop now with slow connection so can I ask if
you're using an antenna cable to extend the reach of your omni antenna
with this usb client adapter and does the same outfit sell that cable
with the antenna they sell; how long is it? Or does the cable have to be
ordered separately? also, might be easier to use a usb device surrounded
in a home made dish antenna rather than using an omni which is not as
efficient for directional reception.

Yes, there are now USB adapters with antenna jacks availible. They
have their built in antenna plus the possibility for external makes
them useful for even very long range connections. It all depends on
the antenna.

No antenna cable required or desired. That's the great advantage of
USB or ethernet wireless adapters. Antenna cables lose signal
strength. Don't use them if possible to avoid and if you do, make sure
it's very short.

IWhenever possible, extend the USB cable, and put the radio right
where you want the antenna to be.

Here's a link for a complete setups with USB adapter antenna and
sometimes a cable. The antenna cables they use are somewhat low loss
so not too bad. I cannot recommend the brand, have not tried them,
but this will show you some options.

Personally, I have not have any luck with homemade dish antennas on
USB adapters.

That's why I prefer a USB adapter with an external antenna
connector. A simple omni antenna will give a noticable improvement
over the built in antenna, but you want to optimize your connection,
then get a directional antenna. Be careful if it comes with it's own
cable, because again, these lose signal quality. Short cables as a
rule...

Here's a couple of inexpensive antennas (N connectors require adapter
to RP-SMA) :

The Hawking USB adapter /dish antenna that was recommended is probably
a good option also. Might be easiest just to get one of those and an
extension cable. It's not as flexible as being able to use any
antenna you want, but should be fine for most situations.

To sum up, get a Hawking USB adapter with the dish, or else a USB with
external antenna adapter. You can buy a kit with antenna from company
above or buy the devices separately and maybe adapt the antenna to the
USB connector.

If it does not reach where you want the antenna, get a USB extension
cable as linked above.

Hope all this helps and does not confuse.

Broken link again, sorry. This should work:
