Router only allowing 1 machine online

[Dutch Squirrel]

Hey all.

I've come across a setup using telewest (UK) cable internet, through a cable modem into an edimax router.

Basically, I've been told that it's only possible for one machine to access the net at once.

I've already been to remove some spyware/trojans from one laptop, which has a wireless card - I checked it out while the scan progressed, and sure enough, with somebody connected to the router by ethernet, the laptop machine was getting no internet.

I can log into the router wirelessly fine from the laptop, so I made sure DHCP was enabled, and made sure the usual client settings were set correctly.

An ipconfig/all showed all to be healthy looking too.

Has anyone any pointers to check, and/or does this sound at all familiar to anyone?

Is it possible the wrong kind of router has been supplied or similar? ie this is CABLE not ADSL...

I look forward to any replies.

Do you have any type of encryption on your wireless network? (WEP, WPA, etc.) Also have you tried hooking up the ethernet cable to your laptop to see if it can still get internet when it's not wireless?

Thanks for the reply.

There's no encryption set up, no.

I haven't tried connecting more than one machine via ethernet cable yet, no, but I will do when I go back, no doubt.

I was just wondering if there's anything else to look out for, as it seems a little odd to me - I've come across a similar problem before and couldn't solve it.

im tryin to think of what could do this because I haven't ever come across this problem. O.o But if your ISP is telling you that you can only have one computer hooked up to the internet, they probably aren't talking about with the use of a router or other hardware, since you can only hook up one computer to your cable modem, but since you have a router you can hook up more than one computer. Your cable modem supplies the IP address to your router, your router can then make up as many IP's as it wants to, to give internet access to other machines. Do you live in a densly populated area? It's possible that people are getting on your network and taking up all the bandwidth thus not allowing you to use the internet. I'd try hooking up your laptop with the ethernet cable to the modem and if that doesn't work go into your router configuration and check to see if there are other people on your network. (You can view who is on your network in your router config) If no one is on your network then i'd try setting up static IP's for your desktop and laptop and see if they can both work with the internet. Don't forget to do a ipconfig /release and /renew on each computer before you set your static IP's.

There is an internet connection that works fine.

The router just will not share it between more than one machine at present and I don't see why.

I've checked that DHCP is enabled and there is no security enabled yet (WEP or MAC address filtering).

Anything else to check for would be much appreciated.

Thanks.

just thought of something, in your router settings is there an option that says "Maximum Number of DHCP Users?" and is it set to only allowing 1? If so change it to like 4 or 5 and see if that fixes it.

With some ISP's you have to clone the MAC address of the computer thats connected to the router. Log into the router and see if there is an option to clone the computers MAC if so enable it and clone it. Post the make and model of the router just to give us an idea of what device you are working with.
