You could also get extension usb cables, and run your usb wifi
adapter outside, or to the garage, or wherever you get signnal. This is
the solution im using for local folks that cant get a decent signal
level inside thier rv. I got some 15' usb extension cables on ebay, and
15' isnt too far for usb (I havet had to try using 2 extensions yet,
but im leary that wont work...)
You will have to test this with the specific hardware and the specific
cable. There are wide variations in how well the various USB companies
have implemented their circuitry. There is a written spec which gives
reasonable margin, but that spec is often ignored if the product
happens to work on a 5 meter cable.

Buying high gain antenna will make a big difference, its really needed
for the xmit antenna (many units have 2 antenna one rx the other tx),
its the tx antenna that will benefit the most, and putting antenna on
the access point will be more effective than on the adapter.

Not sure what you mean by that statement. In terms of improving
the connection between two systems improving the receiver is
equivalent to improving the transmitter. Same for the antennas.
I can see two places where this would not be true. If you have
more receivers than transmitters then upgrading the transmitters
is more cost effective. And if you have significant background
noise then boosting the received signal will also boost the noise.

Thanks for the tip!
Some Background: I use a wireless share for my connection for my web
access. I pay my house mate to be part of his network, so this is
not road warring! I am on the edge of the wireless router range, so
the signal is weak to begin with and drops out frequently
complicating my wireless technical development. I have setup a test
station that is much closer to the router, but its cold in the
garage, if you know what I mean!
Buy a higher gain antenna. Better yet, buy two. One for the client and
one for the WAP. I've used these [1] in the past and they are well
worth the money. Gained an extra 200 feet in one direction and a solid
signal through three walls in th other. If you watch you can get
them
for < 15 shipped after rebate. Or you could always build your own
antenna...
I would like to have a conversation with you about antennas. Ben
recommended a bridge and I appreciate that offer, but this wireless
share is transitory. Wireless bridges are generally expensive and if
the share situation changes I could end up with a bridge to nowhere, so
to speak.
The picture of the high gain antenna that you suggest show the antenna
on a pedestal, held down with a nut. Do I remove the nut and fasten
antenna onto the post of the WAP w/ its antenna removed or is there some
connecting hardware not shown?
Building an antenna sounds interesting, do you have "hands on"
experience there? I would need some tech help on that.
Given that I don't know much about wireless accept what I have
learned from trial and error, it has been rough to get to a Linux
implementation of wireless networking. At present I am still using
windows. Frankly, I just kept giving up too easily and never really
tried to get things running, as other work has take priority.
What card are you using?
I have four cards, all D-link. I have no allegiance to D-Link, I just
bought a set, on sale: wireless router, PCI and USB cards when I got
started looking into wireless. I am working on the assumption that I
have to test these cards under Windows to prove a "known good" status
before delving into the Linux unknown.
DWL-G510 (PCI) this card had a history of flakyness under WinMe (hey,
its Me what did I expect. I haven't tried it under XP. The one thing
PCI does seem to have is greater range!)
DWL-G520 (PCI) this card was found in a computer by side of the road
that some Frat Boys had take a baseball bat to. Status unknown.
DWL-G120 (USB) this card is the one I use primarily. It has a long
dongle cord and I have it run up the wall close to the ceiling. When I
was playing with setting it up with Ubuntu I ran into the "which rev is
the chipset issue." I chickened out on opening the housing to view the
chipset, as this is my web access, unless I want to sit in the cold
garage and I don't.
DWL-G122 (USB) this card in promising. Ubuntu showed a Marvel chipset,
if I remember correctly. The issue with these thumb drive type wireless
cards is signal range; and with a short dongle cord to a pedestal base,
I can't work the antenna directionality as I would like.
Give me till after the holidays, I would like to revisit this discussion
and solve this problem once and for all. Also, I got a how-to specific
to this DWL-122 card and Ubuntu and it mentioned the software setup.
I'll have to find that documentation.
As with everything Linux, while I've been frittering, someone has
already solved the issue and I just need to update my OS version, etc,
etc. will probably be the case.
Here is my question: should I stop worrying about virus protection
and make implementing Linux wireless my top priority, because virus
threats are low under Linux; Therefore, would I be better off running
Linux, with no virus protection, then to keep working with windows
and outdated AVG software?
That's up to you. If you are going to keep using windows, then get an
A/V solution. Also, make sure you are running Firefox and Thunderbird.
I am running Firefox and Thunderbird.
Thanks Garl,
