Hey, if only one person enjoyed it, I tell myself it was all worth it.

> I did have a question.
>I have not looked at wireless in some time as my network at home is wired.
>But I thought that wireless was mostly line of sight only.  
Line of sight does apply, but only in regards to WANs, MANs and large LANs.
For your typical household/neighborhood/small-office lan, line of sight 
isn't an issue.

>From what you are doing that must not be the case anymore?  How about 
>inside of a house can the wireless signal go from room to room and to 
>different levels in the house? 
Yes, no problem.  I can stand two houses away on either side with my 
laptop, and connect with little problem.

> Is it as reliable as a wired network? 
No, notice I said "little problem" above?  The further away you are, the 
less reliable it gets.  The radios used just don't have enough power to go 
very far.  HomeRF cards are rated at 150'; at 100' my pings drop to 85%, at 125' they drop to 70%, at 150' they drop to 35-50%, at 180' they don't exist.

If you want to hook up your moms house, across town, you'll need to buy a 
wireless WAN bridge setup, which can be had, SLOW and USED and LOW END, for 
under $1000, FCC license free.  When I say SLOW, what I really mean is 
typically less than a Mb/s, anywhere from 200Kb/s through 800K/s.  I'd be 
willing to bet that if you've got some real money to spend on something 
decent, Koree would be quite willing to help you spend it, for a small 
handling fee.

NOTE: if you buy one of those used FCC license free systems, like Koree 
said at our last meeting, it's only FCC license free as a total, installed 
package.  If the system doesn't come complete, it isn't compliant.   You 
may be wasting your money, and possibly risking fines from the FCC and 
law suits from business/goverment entities who experience disruption to 
communication because of your non-compliant system.

>Would it be possible to have both wired and wireless at the same time if 
>you had standard NIC's and wireless NIC's installed?
Yes, as I said in my other post, both wired and wireless clients at my 
house use the same DHCP server, and are able to see each other with no 
problem.  Currently, that is.  I'm not sure I can trust all my neighbors on 
my network, and will soon be quadruple homing my router/firewall.  And, 
maybe, converting it to Linux, we'll see.

Quite welcome,
William

I don't check my email on the weekends, so don't expect any more input from 
me until Monday. wu
