Ärende: WiFi <> hardwired routers
=================================
Question ..

From recent work I know that the Linksys WRT-54G units will permit satellite
connections with OS/2 computers via the hard-wired cable modem used for the
Hughes satellite operations.  In that these Linksys products generate DHCP
private address LAN connections, I've had no problem at all using that LAN
address and hub/router operations as needed with OS/2 PEER operations.  Works
just fine.

And as well, these units will also enable a WiFi operation that is also
supported on the basis of the modem connection to the Hughes bird. Which
probably will work with the OS/2 Thinkpad WiFi chipsets if we go through the
whole complicated mess of finding the right driver and setup mish-mash for the
appropiate Thinkpad model and whatever chipset or card which is used to do the
WiFi connection with the laptop.  But that's not a simple deal per what I've
been reading through Rosenthal's work...

The research on the above was done to help enable full high speed data
connection capabilities in the middle of nowhere, or wherever even civilized
where that form of high speed link to the bird was needed and could be used if
the bird could be seen from the site.

But now let's add two more wrinkles.


OK .. now we want to develop the next part of the system.  Suppose we have no
access to the bird, but do have a shot at an existing WiFi operation which we
wish to use for a routed system to the hard wired complex of OS/2 Thinkpads at
a site.  In this case, the WRT-54G (series) of these Linksys units isn't what
we need.  We need something which will find and connect to the (an) available
existing WiFi network.  We then need to cascade that connection, as if it were
a 'modem' to whatever we are using for a router.  Such as the existing WRT-54G
unit?

What do we do here?  Is what is needed a WAP-54G Linksys Access Point unit?  Do
we let it connect to the existing desired WiFi access and then use the R45
cable connection on it?  Do we then jam that into the modem connection on the
WRT-54G existing router?  And then it lets that unit go back to servicing the
whole LAN private address game from there? Just like the Hughes bird does?


OK .. that said, now for the next question.  Suppose that we still have a
functioning hard wired cable or DSL service at a given point which lets us get
to the IP.  But we want to creat a WiFi operation from that. Which .. of all
things .. could be accessed from yet another location by the above method?  Can
this be done?

Can we take the WAP-54G unit and home in on our own generated WiFi operation
from whatever we use for that, such as a WRT-54G seried unit dedicated to that
service at the still alive hard line IP service?  And then cascade that
generated service to afar?

The reason for the complexity really has a reason to be asked.  Here it is.  It
may not be widely known, but Amateur Radio 2.4Ghz assignments do include
several channels in the WiFi Part 15 arena.  More important per an article in
this month's QST magazine, the Linksys WRT54GL version which uses a LINUX based
operating system, can be and has been modified by several groups to customize
that unit for work with full higher power amplifiers and antenna combinations
which can greatly expand the coverage area for WiFi for Amateur Radio service. 
And that opens up a VERY important emergency service platform for disaster
relief, it would seem.

That technique could be used for disaster relief service for a  whole
metropolitan area network (MAN) service.  Which could cover a huge area of
absolutly critically needed IP connectivity for emergency communications via
secured WiFi/VPN  .. and .. similarly modifiable access points. Which just
might have a future via what I am wondering about as a use for the WAP-54G
Linksys Access Point technology when paired with this technique.

Would somebody here be able to point me in the right direction for researching
this Access Point technology?  Standard WiFi would be fine for the first phase
of the research.

The trick is to interface the standard technology against the local LAN without
going through the mess of customization of each Thinkpad for this or that
hardware.  Make it pure old LAN techniques please.  Much simpler for rapid
setup of emergency oriented stuff, as I see it and does work beautifully at
this point with the Hughes bird stuff right now.


Thanks!
