Hi guys,

I was hoping i could find some help with my problem.

We have one line at home with three jacks. The one jack is connected to the phone with a filter. The other two we want to use for Internet ADSL, at the same time if necassary. So i bought two DLINK 2500U routers to connect to the jacks. One for my dad in his office and the other for me in my room.

Now here's the problem. It seems we cannt have two connections going through the line at the same time. If my router is connected to the internet and working fine, as soon as we connect the other router at the other jack, my router's dsl disconnects and the only way for me to get back on is to disconnect the other one and vice versa. This is the actual physical dsl internet connection itself not the ISP i am referring to.

I was under the impression that it is possible to have two connections on the same line? Am i mistaken? If not what could the problem be??! Do i need to have filters at all the jacks?

Any help would be appreciated. Thank you in advance :)
 
It is not possible to connect two 2500U modems on a single line at the same time. You could run two or more connections to different ISPs over one Dlink 2500U with the correct network setup.
 
You can't have 2 routers on the same line AFAIK.

However, you can put your router in bridging mode. Then you can dial more than just 2 connections from the other PC's via the 1 router.
 
Ok thanks guys.

So basically i have to find some way of networking the two computers through one router? Great...since they are on opposite ends of the house :/

easiest and most stable solution... run network cable through the roof.
 
Matrix warehouse has plenty cable you can give them a shout.

should look at ethernet over powerlines that should solve your problem
 
Option 95:
----------

You already have a cable running to the other end of the house, it's the Telkom cable.
This cable has 4 or 6 wires in it.

This means that you can use the existing cable as a CAT3 network cable.
CAT3 will work fine for transmission speeds of up to 10MB/s, and, our ADSL is not going that fast anyway.
Some people report speeds of 100MB/s on CAT3 cables on distances of less than 100m.

Most routers / switches should be more than capable of downgrading to a CAT3 network cable, as they are supposed to be able to automatically "downgrade" on a damaged CAT5 cable.

CAT3 wiring diagram:
Holding the network plug in your hand, with the end that goes into the computer facing away from you, and the silver contact points on top, pin 1 is the leftmost pin.
1 - 1 - Wire same color on both ends
2 - 2 - Wire same color on both ends
3 - 3 - Wire same color on both ends
4 - nothing
5 - nothing
6 - 6 - Wire same color on both ends
7 - nothing
8 - nothing

Unfortunately, you cannot test if your router will be able to use CAT3 without actually making the cable and doing it. You could try stripping the middle of a working old network cable and cutting the correct 4 wires first to test if the router can support CAT3.

Good luck.
 
Oh ya, I forgot to mention, it helps to manually set the network card on the receiving machine to 10MB/s if it automatically sets itself to 100MB/s.
 
ethernet over power lines now thats an IDEA anybody got more details, experience with this like does it work in SA or with pre-paid electricity boxes, or just where to buy thanks
 
Seriously guys. A nice Cat 5 Cable thru the roof is really the easiest and cheapest option here. I mean seriously shouldn't cost much more than R 350.

100meter x Cat5 Cable - R3 / meter
2 x RJ 45 Connector - R1 each
2 x Boots - R1 each

Total R 304

ethernet over powerline works but only for local networking not for wide area networking

Yes because he doesn't want to connect two machines in his house, but the entire neighborhood. Dude, do you even read?

To the OP, you can go Wifi, but if you have a lot of walls in between the router and your dad's pc like you say, signal may be an issue. Getting some Cat5e cable and running a line through the roof would definitely be your most reliable and stable form of connection and it'll plug up security holes created by wifi as well.
Just remember, you'd need a crimping tool too, if you can't borrow one, in order to put on the plugs.
 
So here are your options, summarised:
  1. Run an ethernet cable through your ceiling.
  2. Buy a WiFi router/AP that supports 802.11n. The Netgear wireless-N range promises greater/better indoor coverage than regular 802.11g devices
  3. Buy an Ethernet over Powerline kit.
  4. Use your existing Telephone wiring - convert it to Cat 3.

I think option 1 is the most suitable, and cheapest option.

Here's an idea:

Since you have 2 modems already, all you need to do is buy the cabling, and install it. I'd then use one of the modems as a switch (it most likely has a built-in 4port switch), by sticking it in the ceiling somewhere.

You can then connect up other rooms, and your Home Theater system / PS3 to a home network.

Your ADSL-connected modem-router will act as the modem, router, DHCP server, DNS server, gateway, and firewall, while the other modem-router sitting in the ceiling just acts as a switch. So all your wiring will converge in the ceiling - keeping the mess hidden away.
