--- Excerpt ---
The Linksys WRT-54GL is verson 4 of the WRT-54G. With version 5 of the
WRT-54G Linksys changed the hardware and stopped using Linux internally.
Because of these changes the device could no longer run third-party
firmwares.

As for Hughes satellite connection, I can't say but, I have a Starband(it)
satellite modem. I've had my system since before they made a simple
router, so this requires proprietary WinXX software. And for that purpose
I have dedicated machine that does nothing except run that WinXX software
and a LAN to my OS/2 machine. That extra Win machine and LAN card and
satellite-modem can be eliminated by paying more for a single device
satellite-modem-router. Unfortunately that device is not made by CISCO
nor Lynksys, rather it is another Starband(it) proprietary device, and
like their modem it has some very serious technical design mistakes which
make it unreliable to the point of dying if exposed to heat (non-air
conditioned summer).
When I first got this system several years ago I experimented with OS/2
bypassing the WinXX trash and was able to ping and get a response through
the satellite system. But I was never able to pass useful data such as
from an HTTP connection. The reason being the other end of the satellite
up/down link uses a complimentary WinXX software, for which there is no
OS/2 equlavent.
All those problems aside, a satellite ISP will indeed provide service in
spite of any local castrophy to the typical net connections. As far as
the user's computer is concerned it is just an ordinary router connection,
with the ISP having a specified set of quad addresses.
The rest of your questions seem to revolve around WAP and WiFi. I don't
use those, so I'll leave that to you to do a web search for.
I will be interested in your results. I also experimented with my cell
phone using a data link cable to the computer and was successful
connecting to the net via Cingular Wireless. Unfortunately Cingular
abandoned their former cheap ($5/mo.) data service that worked very well
(although not wide band), for a new "will be working outside of NY NY some
year" service that is very expensive (~$80/mo.) So I quickly abandoned
that experiment (and paid $20 for 5 minutes of data service).
I will comment that StarBandit costs me $70/mo. and is plagued with down
time, and bounced E-Mail due to viruses and their selection of software.
So both that and the Cingular data plan are fairly expensive. This puts
them in a class with a direct satellite phone such as Qualcomm GSP-1600,
see http://www.globalstarusa.com/en/buy/ . Like the cell phone that can
be connected to a computer via a data cable. Of course using such a
device might put you in a class with drug dealers and spies. <g>
ML> Question ..
ML> From recent work I know that the Linksys WRT-54G units will permit
ML> satellite connections with OS/2 computers via the hard-wired cable
ML> modem used for the Hughes satellite operations. In that these
ML> Linksys products generate DHCP private address LAN connections,
ML> I've had no problem at all using that LAN address and hub/router
ML> operations as needed with OS/2 PEER operations. Works just fine
ML> And as well, these units will also enable a WiFi operation that is
ML> also supported on the basis of the modem connection to the Hughes
ML> bird. Which probably will work with the OS/2 Thinkpad WiFi
ML> chipsets if we go through the whole complicated mess of finding
ML> the right driver and setup mish-mash for the appropiate Thinkpad
ML> model and whatever chipset or card which is used to do the WiFi
ML> connection with the laptop. But that's not a simple deal per what
ML> I've been reading through Rosenthal's work..
ML> The research on the above was done to help enable full high speed
ML> data connection capabilities in the middle of nowhere, or wherever
ML> even civilized where that form of high speed link to the bird was
ML> needed and could be used if the bird could be seen from the site
ML> But now let's add two more wrinkles.
ML> OK .. now we want to develop the next part of the system. Suppose
ML> we have no access to the bird, but do have a shot at an existing
ML> WiFi operation which we wish to use for a routed system to the
ML> hard wired complex of OS/2 Thinkpads at a site. In this case, the
ML> WRT-54G (series) of these Linksys units isn't what we need. We
ML> need something which will find and connect to the (an) available
ML> existing WiFi network. We then need to cascade that connection,
ML> as if it were a 'modem' to whatever we are using for a router.
ML> Such as the existing WRT-54G unit
ML> What do we do here? Is what is needed a WAP-54G Linksys Access
ML> Point unit? Do we let it connect to the existing desired WiFi
ML> access and then use the R45 cable connection on it? Do we then
ML> jam that into the modem connection on the WRT-54G existing router?
ML> And then it lets that unit go back to servicing the whole LAN
ML> private address game from there? Just like the Hughes bird does
ML> OK .. that said, now for the next question. Suppose that we still
ML> have a functioning hard wired cable or DSL service at a given
ML> point which lets us get to the IP. But we want to creat a WiFi
ML> operation from that. Which .. of all things .. could be accessed
ML> from yet another location by the above method? Can this be done
ML> Can we take the WAP-54G unit and home in on our own generated WiFi
ML> operation from whatever we use for that, such as a WRT-54G seried
ML> unit dedicated to that service at the still alive hard line IP
ML> service? And then cascade that generated service to afar
ML> The reason for the complexity really has a reason to be asked.
ML> Here it is. It may not be widely known, but Amateur Radio 2.4Ghz
ML> assignments do include several channels in the WiFi Part 15 arena.
ML> More important per an article in this month's QST magazine, the
ML> Linksys WRT54GL version which uses a LINUX based operating system,
ML> can be and has been modified by several groups to customize that
ML> unit for work with full higher power amplifiers and antenna
ML> combinations which can greatly expand the coverage area for WiFi
ML> for Amateur Radio service. And that opens up a VERY important
ML> emergency service platform for disaster relief, it would seem
ML> That technique could be used for disaster relief service for a
ML> whole metropolitan area network (MAN) service. Which could cover

ML> emergency communications via secured WiFi/VPN .. and .. similarly
ML> modifiable access points. Which just might have a future via what
ML> I am wondering about as a use for the WAP-54G Linksys Access Point
ML> technology when paired with this technique
ML> Would somebody here be able to point me in the right direction for

Thanks and Good Luck, Andy Roberts
