Some advice needed.

My Setup.

Main PC, Sentech Desktop (overpriced) modem connected via USB.
Connects to a standard switch/hub
A wireless router (micronet SP918GL) plugs into the hub to support my laptop. Access controlled by mac address.

My problem

I want to install XP64 to test our software on, but need to have internet access. So, as i can't get drivers for the modem yet, i want to set it up using the ethernet cable i bought.

I remember setting up my old ADSL using PPPoE and i guess i can do the same with this modem. However this was a while ago and i'm not sure what the best way to do this is.

Finally, the question is:

Is it as simple as just plugging it in the hub and creating a connection? Does the wireless router need to get involved anywhere? Any other suggestions to get this all working?

Thanks for any help.

If I misunderstand you, please correct me,

Plugging the Modem into the Hub with PPPoE cable will not work. The PPPoE cable needs to be directly connect by ethernet to a device. You are going to need some sort of gateway device. I.E a broadband router (Linksys, Dlink etc), a linux box running say IPcop, or Internet Connection sharing on windows.

That micronet Wireless AP you have, is just a normal accesspoint according to the website. Meaning it doesn't has the facility to handle a PPPoE connection.

The only thing you can do with your current setup is connect the Sentech with PPPoE cable directly into the Ethernet port on either the laptop or PC (Depending on which on you are installing WinXP 64-bit on) and configure the connection as a "Broadband connection that requires a username and password". However you won't be able to share your internet connection while it's connected.

If you only have one ethernet on PC for example and you plug the Sentech with PPPoE cable into it, you don't have any way to connect that system to the hub so you laptop or anyone else can access it.

The only thing you could do is get an old box, install ipcop of something and share it that way, OR get a Broadband Router (Wireless or not) with an internet port.
 
Thanks Crash.

Makes sense.

I have a spare network card i can install, so from what you are saying, i should be able to install it in my machine and use it to connect to the modem, leaving the other one plugged into the hub/router.

Or, even get a wireless card for the PC to free up the ethernet port.

So, with this in mind, can the new IP address of the card be on the same subnet and just use it as the gateway address?

thanks again

Hi, any help will be appreciated..

I previously had Sentech, connected to my wireless router, connected to two pc's, which worked. However, I left my previous employer and had to hand the Sentech modem back. So, I went and bought my own, changed the userid's and passwords and no matter what I try, will not work. The only way I verified that the modem works, is by connecting it via USB to one machine.

Any ideas please ?

Thanks!

I have two Iburst modems connected directly to my switch. Attached to this switch is also a MythTV media server and gateway server, a gentoo desktop and a windows xp desktop.

I set up a simple PPPoE broadband connection that requires a username and password in the "New Connection Wizard", and out i go through the one modem.

The two linux machine connect through the other modem.

You can do PPPoE on a switch.

I have also done this with one of those Wireless SOHO routers.
 
OK, i'm gonna try it now... so if you dont hear from me ever again, then its all gone horribly wrong ;)
 
nope. didnt work.
Tried plugging it into the hub.
Then put another card in my machine and plugged it into that. still no joy, but i think the cable is to blame as network icon said "cable unplugged"
 
He doesn't have a switch he has a hub..... :)
Thats why I said "Plugging the Modem into the Hub with PPPoE cable will not work. "

roddyp, I have never had much luck running multiple network cards on a windows box.
If memory serves, there is a piece of software you can install that comes with windows that can bridge the network cards.

Silvertip.... when you connect your Sentech by USB to the other machine, does it connect and work? Can you browse? Or are you just checking that it has signal with the software?
 
The bridging for the network cards is there to join up two networks on different subnets. The bridge also only works on two network cards that are not sharing internet connections.

I've got the cards installed and running pretty happily, and I'll go and pick up an ethernet cable 2day and test it and post my results

Ah- no, not so much. I've often hooked my modem up via Ethernet through an old 3Com hub and a li'l Sky Link NET1008 "8 port N-Way Fast Ethernet Switch" so I could leave my modem on my workbench and sit on the couch with my laptop. All it takes is to run a WinXP PPPoE session to get connected.

Hell, I've gone one better: on an XP box with one NIC, I've done the above mentioned as well as setup XP's ICS, so as to allow a second/more PC's on the LAN to connect through that 1st one acting as a proxy.

More: I've got a site where the modem has to be by the window (to be near its HGA) but it's MUCH too far away from the server box. This was very simply fixed by plugging the modem Ethernet cable into a handy wallbox so the connection could be extended across the room and then plugged into the server from the patch panel. That job may have been a 2 NIC solution but I can't recall ATM.
 
Just one quick tip when it comes to using an ethernet cable. There is a link LED in a black box on the cable. If this is not shining bright green there is a problem. When moving from USB to Ethernet and vice versa, you have to turn the modem off and on again to get the modem to detect what kind of cable is being used. This has had many a poor sucker (including myself) scratching their head.
 
Connection - thanks for the tip. Have been stuggling for ages. Thought my cable was faulty. turned off the modem, plugged it into my second network card and turned it on again. working like a charm. Now to install XP64.....
 
OK, final plan has been made and thought someone out there might wanna try the same.

I have attached my sentech modem using the ethernet cable directly to the only ethernet port on my wireless hub. (micronet SP918GL)
I then installed a wireless card on my main desktop machine and connect to the modem (now sitting about 20 meters away in my kitchen for best reception) via the wireless hub.
The other machines in the house (2 laptops and a mac) connect to the wireless hub as well and use my main machine as the internet gateway.

All in all, a great way to connect if you want to seperate your modem and machine by more than 3m. (especially useful if reception varies from room to room)

Correct me if I'm wrong but I think there's a misunderstanding somewhere.

PPPoE = Point to Point Protocol over Ethernet

PoE = Power Over Ethernet

Quite right wiki :) ..but from what I've read we are all on the same page chewing over fun and games with PPPoE: of course now I'm (idly!) curious about powering a modem via PoE and running it via PPPoE too!

It shouldn't be too challenging, it's all about voltage and that's pretty easy to manage ..oh- and that *ridiculously* small power connector but I already know where to get those! :P
