Connecting 2 PCs via one ADSL router

[sia]

I have an Asus 602 ADSL combo router that has both a LAN and a USB port. I have connected two PCs, one through the LAN and another via USB. Now they both can connect to internet and they also can connect two each other. I have share folders in both that can access from the other.

I have an ADSL 64kb/s connection that needs a user name and password. My problem is I can connect to internet with both PCs, but not at the same time. Is there any way to solve this problem?

Sounds like either a setting in the router or your ISP only allows one connection at a time.
I looked on Asus and could not find the model you stated. I wanted to look at the manual to see something about settings.

You are probably being limited by your ISP and your modem. Almost everyone I have seen with a USB and RJ45 connection is either or, not both. You can probably call your ISP up and ask to allow multiple computers on your connection at a time (they will gladly do this for an additional fee each month).

Or you could buy a router that has an integrated switch and connect up to four computers using it.

ISP will not be able to see how many PCs are trying to connect as all it sees will be the modem after I do some port forwarding.
I looked on Asus and could not find the model you stated.
Important point, because I couldn't find it too. It seems such thing does not exists. I don't know why. Maybe they released it for a special region.

That might not be true. Most routers include a switch that allows multiple computers to connect. There is a good chance you have just a modem, and when the second PC connects it requests a public IP from the ISP. Then they know you are trying to setup more than one PC.

Is THIS IT? (http://www.asus.com/products.aspx?l1=13&l2=96&l3=0&l4=0&model=1105&modelmenu=1)

Generally if the router only has one LAN port you will need to connect it to a switch and then connect each computer to the switch as well. Like Erik, those I have seen with both USB and LAN are either/or.

port forwarding should be unneccesary for regular websurfing as the router should handle basic NAT tasks. for ease(at least initially) I would have thr router setup to act as DHCP, and configure the PCs to receive addresses.

....I have an ADSL 64kb/s connection that needs a user name and password. My problem is I can connect to internet with both PCs, but not at the same time. Is there any way to solve this problem?

When you connect to the internet do you login with username/password at both PCs?

If so this is your problem. Like others have said it sounds like you have a ADSL modem with a both a LAN and a USB connection. ( I have a cable modem with a USB and LAN port too, it just gives the user more options).

Modems however do not store ISP login information like wireless routers do. So once you login with one computer thats it.

As already suggested you might want to just get a router and set it up between your ADSL modem and your computers.

Hope this helps :)

This may be the case with modems in Iran, but it is generally not the case with modems in general. Most modems are not just modems ala dial up modems. It is probably a PPPoE connection and the software on the machine establishes a connection as Pave Spectre alluded to OR you need a switch plugged in to the LAN ethernet port as Erik says.

I wonder when you connect a PC and get a internet connection, do you get a public IP address or a 192.168.X.X address on your PC? When you are connected, click Start, Run and type cmd then hit enter. Now type ipconfig /all and copy the data to a reply post.

This is a big piece of the troubleshooting puzzle. We need to know if your PC has the PPPoE software on it and establishes authentication or the Modem does. IF you have a 192.168.X.X address it is likely your modem is a router doing NAT and DHCP and the issue is DHCP and you need a switch. Some ISP's only allow so many machines on the LAN side. IF this is the case, you need another router. But for now there are to many variables.

The server IP address is 192.168.X.X. I use username and password to connect on both PCs. While both PCs can connect to internet and with each other, I can't see why they both can't be connected to internet at the same time. I think PPPoE is on my PC and there is an option on my ADSL router which is set to bridge. ISP login information is stored in PC I think.

Try setting the router to do PPPoE instead of the PC.
