Here’s my scenario, the setup that I wanted is to use the laptop1, laptop2, and my desktop to be in the same local area network. From what I had setup above, my local network can only findlaptop 1, 2. Desktop considered as an outside from my local network. The router im using is netgear wire/wireless router. i couldn’t figure out how to accomplish this.
Can anyone help me with this.?
note:
From DSL modem to desktop is a usb connection, and couldnot be changed.. “if this is ethernet then i’m done”... :?
i suggest a usb router so you can connect it before the pc. That way it routes the internet signal without depending on the pc being on…you could save money by getting a wired adsl router and adding the wireless one to one of its ports, (money is saved because wired routers cost less than wireless ones)
laptops and desktop are all connected directly to router?
In that case they are all on the same network so it must be workgroup settings or some other software issue stopping them see each other…
Im assuming your desktop is running WinXP. Most likely the problem is that the desktop is being assigned an IP address by the ISP, and the router is creating its own subnet for the laptops. Go into your router settings (you’ll pbb have to do it from the laptops) and turn DHCP off. You may also have to change a setting to turn gateway mode off, depending on your make of router.
Next, on the desktop run Network Setup Wizard. When it gets to the screen where it prompts you to “Select a Connection Method”, choose the first option.
On the notebooks, run the NSW but choose the second option. Afterwards, the notebooks should be getting their IP assigned by the desktop instead of the router, and everything should be ok. Make sure you set any third party firewalls to allow file and printer sharing otherwise they won’t show up on the workgroup. For example, in Zonealarm add a trusted IP range in 192.168.1.1 to 192.168.1.255.
Caveat: I don’t know why you’d elect to use this setup though, since the biggest benefit of using routers is so you can access the internet with your laptops without having to have the gateway computer on. I would recommend you get a DSL modem capable of working with LAN, so you can hook it up to your router. I’ve got a spare DSL modem from back when I was using SBC, if you are interested.[/img]
ADSL modem connected to Desktop via USB (running ICS)
Desktop shared internet to ethernet port and from that port
connected to wireless router
wireless router provides internet connection for all laptops.
i know it is a weird setup but that’s the limitation.
anyway,
Thanks for all suggestions.
again, i cannot change the modem to routher.
this setup actual for my dad’s house in Thailand.
They only have ADSL usb modem.
The agreement with isp is actually for using with 1 computer.
but i figured out to install the wireless router to the pc(shared by ICS).
And then shared the internet connection to other computer.
It’s not big deal, but it’s better to have my desktop as a part of
local area network, so that multiplayer game can be applied ,
printer shared, file server, and rdc sometimes.
One of the ideas is that.. if desktop has two ethernet,
i dont know if i can use of them as the shared internetconnection to the router.
and another connection used as the local area network that connect to the same router at different slot. :?
i’ve no clue how it’s going to be.. i’ll try it.
Assuming you want to get the laptops on the Net, I would go with Mike’s suggestion of getting an ethernet-equipped ADSL modem. The way you’ve got it set up, you’re trying to use Windows as the router. You’ll also be better protected from Internet-based attacks if you put the router between the PC and the modem, as most routers these days act as basic firewalls.
As far as seeing the laptops from the desktop, what ethernet port did you plug the desktop into on the router? If you plugged it into the Internet port (closest to the antenna), you’ve got the cable in the wrong port.
If you did plug it into the right port, on the desktop PC click on Start then Run, then type cmd and hit enter. Type in ipconfig and find the section where it says something about “Local Area Connection”, find the IP Address. If the number starts out “192.168.1”, then on one of the laptops, bring up the command prompt (first sentence in this paragraph) and type in ping 192.168.1.3 (assuming that’s the IP address of the PC) and let us know if you get something returned. If you do, there’s probably a naming problem of some sort. If you keep getting request timed out, There’s something more basic wrong.

interesting idea. i’ll try that thanks.

everycomputer is be able to go online.
but they are not in the same local area network
laptop 1 can communicate with 2 from the local area network but not with desktop server connected before router.
I created a diagram to help understand what I think is going on with your subnets. As you can see since your router is acting as a gateway, it has essentially created its own subnet. By turning it passive, your notebooks will be able to get their ip from the desktop and be on the same subnet.
Nice chart. Thank you jashsu. Yes now i can understand more. the key idea is the turn off DHCP and now other computer will continue with the ip under same subnet.
btw: what program u use to make that chart? photoshop?

Yeah, Photoshop Elements 2… its a pretty capable substitute to “full-strength” Photoshop. It would have probably been easier to make using Visio or something…
If turning dhcp off itself doesn’t solve it, check your router config settings for a “gateway” option and turn it off. Essentially you want to turn your wireless gateway into a wireless access point. Read here for a bit more background.

We had the same thing with NTL (UK cable company). One of their conditions on the internet was that they only supported one computer, not a network. Well we set up a wireless network anyways because as far as they’re concerned it looks like just one computer as they only see the router.
The only time I’ve had to phone them up about something I just said that my computer was directly connected and they didn’t say anything more about it.
Just worth considering for all the benefits mentioned before. And if you did ever have trouble with the internet and they were sending a guy around you could just do a quick shuffle and hook the desktop directly up again… :oops:

does any steps in these process need a crosscable?

No. Crossover cables are only for computer to computer connections. Use straight-throughs for any computer-network appliance connections. (For most modern appliances though, it shouldnt matter, since they all have auto-crossover detection, and change the signal accordingly).
