ADSL line and plugging in two connections to 2 wall points instead of wireless...
why can this not work or could it?
IE I have my pc upstairs plugged into the phone line with an adsl router and its connected. I then have a laptop downstairs with an adsl modem on it and I plug that into the phone line socket downstairs. I would want to do this because I dont want to splash out for wireless equipment when I have two adsl modems.
I am guessing what i want to do can't work. I don't understand why though as surely its just the same as a network connection? Why would I have to switch the connection off upstairs before connecting downstairs? Why can the laptop and the modem not just pick up on the fact the adsl line is already connected and on therefore doesn't need to dial?

I'm guessing the same way that a normal analog modem won't. Does not the ADSL modem need to here a dial tone or something before it tries to connect? Have you actually tried it ?

No not tried it yet but will do once the line has been activated - no money for wirelss stuff and have got a free adsl modem with the connection so sorts out the laptop connection downstairs if it could actually work 
Otherwise I will have to turn the pc off upstairs each time I want to use the laptop downstairs

You won't need to switch the PC off upstairs, just the ADSL router/modem.
I've got a similar setup. We had a free USB modem when we joinded but I soon replaced that with a combined modem/router/firewall/switch. We have a phone line in the lounge as well but rather than run a Cat5 cable down to it from the switch upstairs I'm just going to use the USB modem for the laptop when I need to.
I'd be interested if this works as I've not done it myself yet.

Oh yeah I know I don't need to switch the pc off but thats what I said as if it wasn't connected and downloading then it wouldn't need to be on
What I need is for a telecoms expert to explain why this wouldn't work and whether its the phone line that can't handle it or its the modem/hardware and how it makes the connection thats the problem. Or possibly will be surprised and will find it will actually work but I doubt it, none of my money saving fixes ever do

Yes and No are the answers.
Yes its physically possible to split the line in three rather than two. It is the ISP that will block you from sharing the line. This can be bypassed by using a fake IP software.
Will print up instructions if you like.

Oh and remember if they catch you doing this you will be banned.
In australia, they have 8mbit and 10 mbit using two modems stacked but only one phone line.
In essence you would be stealing double bandwidth.

Ah ok so its the hardware then, ie each modem has to have its own ip address assigned by the provider. Over looked that
I wasn't really after the line being split for a 3rd, more a case of the 2nd modem picking up the fact the line is already connected to the proveider with the pc upstairs already being on and downloading etc. But then it can't do it because it will need to pick up an ip address from the provider for it to speak to the network. ****!
Now whats this fake ip software you mentioned?

Dont think it can be done because it has a carrier frequency that would clash with 2 modems. Unless you can run one at bandwidth higher than another and make sure enough filtering is applied on your line to prevent cross talk between your two carrier bandwidths. By the time you get it working, it would be way more expensive than just getting a wireless router setup.
Just a thought
Just an idea - you could probably setup so that your first modem would use bandwidth bewteen say 100kHz-200kHz for upload and modem B would take up 200kHz-300kHz and then your download would take say 300-500kHz for modem A and then 500-700kHz for modem B. Frequency band is a guess BTW but you get the picture

Try searching for A4PROXY on whatever you favour for downloads 
A4Proxy generates a fake IP when you select one of these options: "Simulate HTTP_CLIENT_IP" or "Simulate HTTP_X_FORWARDED_FOR_IP" (Proxy Options tab). The presence of these variables in the request tells the website the following: "the request is made through a non-anonymous proxy server, and the IP address of the client is x.x.x.x", where x.x.x.x is the fake IP address generated by A4Proxy.
As a result, an anonymous connection made through an anonymous proxy server appears for the website as a connection made through a NON-anonymous proxy, and there is an IP address which looks like a true IP address of the client.
Now, that doesn't mean that every website will actually bother analyzing the "Client-IP" and "Forwared-for-IP" variables. Some websites analyze such info and others don't. Those which do analyze it will be fooled, and those which don't analyze it will only record the IP address of your proxy server.
Instead of sending a random fake IP address, which is the default behavior of A4Proxy, you can also make it send one and the same specific IP address in the "fake info" field. In order to do so, you must first enable one of the simulate-ip options mentioned above, and then create an request modification on the Browser Options tab, to replace the random fake IP address generated by A4Proxy with the IP address of your choice.
If you select "Simulate HTTP_CLIENT_IP", then you must modify "Client_IP" variable. If you select "Simulate HTTP_X_FORWARDED_FOR_IP", then you must modify "FORWARDED_FOR_IP" variable.

I think you got IP addressing and ADSL copper line sharing mixed up - maybe ?

No, this is to surf anonamously so that your ISP doesn't detect to modems sharing the same IP.
The telphone line operates on frequencies and separates into channels. All you need is a seperate frequency and your away.

Also when you say you have no money for wireless, you can get 2 x DLINK PCI wireless adaptors for £9.99 each from ebuyer and and share the connection.
Under £20

Unfortunately those adapters would be no good as i've not got a wireless router to start with. I'd need a wireless router and a wireless connection for the laptop so probably about £100 to splash out. Being in a new house thats so far down below other things that I have to buy I wont see that stuff for years I shouldn't imagine

This will not work. ADSL modems work by using the higher frequencies not used by voice to connect to the DSLAM in the exchange. Two modems on the same PSTN circuit would simply throw each other off every time they connect because they are both trying to do the same thing. More info on how ADSL works here http://www.adslguide.org.uk/howitworks/
It is of course easy to connect 2 (or more) PCs to an ADSL router/modem by either connecting both machines via Ethernet cable to the Router (assuming it has a built in switch/hub) or connecting a hub/switch to the router and then connecting the PCs to the hub/switch. This will require you running cable (Cat 5 Ethernet) from the downstairs PC to the router upstairs.

Cheers Jeff, yeah had it connected by cat5 before, I lived in a flat before though so all my computer stuff was on one floor and pretty much in one room. Now in a house and pcs are upstairs so wanted to use laptop downstairs just for checking email and browsing and as I had a spare adsl router wanted to know why it wouldn't just pick up on the connection. I totally overlooked the ip address is assigned to the modem!

You don't need a wireless router to share an internet connection just the two cards, one PCMIA and a PCI (wireless) for under £20.
Then use internet connection sharing.
I have done this on the cheap for someone and it works fine.

Using a wireless router is a much better solution, as most of them have basic firewalls built in.
(Oh, and a USB WLAN 'dongle' is more transferrable than either a PCMCIA or PCI version, and probably cheaper.)

But he stated that "I don't have the money for that"
So P2Peer net it is then.
And yes it has to be on one computer all the time, so if it not in a bedroom then no problem as this used very little power, esp if monitor is off.
Of course I release router is best option, but after being told its not an option, I see no problem with my solution, which is tried and tested.
Then of course at a later date add a wireless router/switch with hardware firewall and you already have the cards.

Oh and please point me in the direction of a USB dongle (wireless) cheaper than £9.99.
That is the same price for a PCMIA as well.
