Use AdHoc or Wireless card and router

#1 (**permalink**) 10-16-2006, 01:49 PM

I'm still trying to figure out what is going to work and was wondering if
someone can answer these questions. To keep it simple I have a PC in my shop
"A" that needs to connect to my wireless signal and internet connection "B"
in my house using high gain antenna and then I still need my viewsonic
display to be able to talk to computer "A" while I'm in the shop . I have
several options available and was wondering what others would do. Getting a
signal from "B" works wth both a wireless G card and using a router running
DD-WRT in Client mode. But what is the best way to allo my viewsonic monitor
to see the computer in my shop "A"

1) Would it be best to just use my wireless card and set it up as an AdHoc
network?

2) Can a wirless card in a PC in ADHOC still connect to a remote wireless
router and then reshare the connection locally?

3) I managed to get my card to prodcast in AdHoc last night but it was using
my PC name as the SSID and wanted a WEP key that I didn't set. How can I
shut off the WEP key request or change it.

4) Which way would get a better signal. A Wireless G card in my PC with high
gain unidirectional antenna or using my Linksys router running DD-WRT in
client mode with the high gain unidirectional antenna.

Sorry another question. Is it possible to use a wireless card and a
hardwired connection to a router at the same time? Can I use the wireless
card to get my internet signal and the router to connecting my smartdisplay?

Only with painful manual editing of routing tables.

Why not use VNC instead to access one PC from the other? That's how I
manage my network server, which has no display of its own.

I own three smart displays that use "RPC" to connect to windows XP machines
over my wireless connection. Before I started this trip each computer was
harwired to a wireless router running XP Pro. When I'm sitting at the PC
coding it works as a monitor but when I start running the code on a machine
I'll get up and take the monitor with me, this gives me the chance to edit
the code and make small changes while standing beside the machine. BUT ever
since I installed the wireless card I can't get the Smart Display to connect
to the computer once it's undocked.

The monitor's are also nice for working on my deck with drink in hand
;-)

John
I've setup my AdHoc network and even though my PC can see the AdHoc
network "RED" and my SmartDisplay can see the PC I can't seem to make the
connections talk. Anyways, what I'm really wondering is... Is it possible to
have the PC (w/ wireless card) in the shop connect to a Wireless Router in
the house but also still allow other computers in the shop to connect to the
ADHoc network and share the internet connection? OR would the PC need to we
hardwired to the router?

In spite of the "A" and "B" description, I don't know what you have set up.
I'd guess that you have a PC with a WiFi card that connects to the desired
router, but your handheld device can't connect to that same router because
of lack of a good antenna.

You want to connect your handheld to the PC for RDC (identical to the VNC
that John suggested, for this purpose).

No. You can't do that ;-)

The WiFi card in the PC needs to be in infrastructure mode to connect to
the router. It cannot simultaneously be in adhoc mode to connect with the
handheld.

You could add a WiFi bridge so that there was a good WiFi signal in the
shop that both PC and handheld would be able to reach.

Or you could add a second wifi gadget to the PC.
That second device would be in adhoc mode to connect to the handheld. It
would accept the RDC connections, and it could also be used with Internet
Connection Sharing so that the handheld could access the internet via the
desktop's other WiFi connection.

Two WiFi devices can be on different networks in the same PC. Not a
problem. You might want different WiFi channels to avoid some
interference, but I haven't even bothered with that in some small trials.

I think it was John that had just such a setup on a sailboat. One PC was
cable to an external antenna to the dockside WiFi, and had a USB "dongle"
in adhoc mode for sharing that connection with a laptop that couldn't
connect to the dockside WiFi.

covers the "sharing" part.

Is this different for Laptops? At work I have my laptop wirelessly conencted
to the router but can use a different PC to connect to the laptop in AdHoc
mode to share the laptops internet connection. This is basiclly what I need
to do at home, I need to ahve the PC connect to a wireless router in the
house but need my local monitor to be able to talk to the PC so that it can
use RPC to run the wireless display.

I don't know how that can work. What adapter is in that laptop?
What is the output of "ipconfig /all" from a cmd prompt on that laptop?

Interesting solution, though I've isntalled the software last night I'm not
reallys ure how to get everything configured. It's going to take at least a
few nights to figure it all out. From waht I've seen it looks like a Virtual
connection is made with any wireless SSID that is open.
