Modem not recognised by computer

When I plug the ethernet cable in nothing happens. The instruction manual says just plug in and connect then it should set up automatically. I've tried resetting pc and router to try again but it still not connecting to the internet.
Any ideas greatly appreciated as I'm struggling what to do now

If you have then try opening a command prompt on the laptop and running the command ipconfig /all (can run command prompt by searching for cmd.exe).
There should be an ip-address on the Ethernet adapter local area connection as well as gateway and dns. If the ip-address starts 169 then there is something wrong with the Ethernet adapter on your laptop.

also there are a few ports on the back of the router have you tried them all?
how many lights are flashing on the back of the pc where the cable goes?
If it helped click the thumb
If it fixed it click 'This fixed my problem'

It sounds to me like the drivers may be missing or if the pc/laptop is old there is a chance the network adapter has failed.
The best way to check if the lan is installed is to go in to device manager and look for something like this.

It might not have the same name as the one in my pic as this is just an example from my pc.
There is a good possibility the network adapter is made by atheros or it could even be intel.

Thanks for the help everyone. Just done this and under the Ethernet adapter connection it says auto configurationIPv4 address 169.254.92. Something (preferred). Is that the one you mean to check for?
Sorry I should have said this is on my desktop pc and I have always connected to my previous broadband provider using Ethernet cable. It's running on vista and when I look in the network and sharing centre it says unidentified network and limited connectivity, local area connection.
I'm lost with all this stuff

The 169 address is the default address network drivers use when they don't have any idea what to do because they are not connecting to the device on the other end of the the cable i.e. your router.
Try going into device manager and see if there are any problems reported there with anything under networking.

I get options to view wireless networks and connect manually to "plusnetwireless4051"
Automatically get new ISP settings for network adapter "local area connection"
Neither will work though.

Quote from: pengbo Yeah that was kind of what I was afraid of umdinga. I think the ethernet in your laptop doesn't have the correct drivers as someone already suggested or when you connected it asked what type of network it was and you didn't choose Home or Work.

So could this be a problem with the supplied router? I have been using the Ethernet connection for my previous router supplied by last isp never had any problem (I don't have that router now tho).
Not sure what I'm supposed to do next, very confusing.

Basically try changing one thing at a time and see if it makes a difference. You may need to reboot the laptop each time, sometimes you don't it can be a bit finicky trying to see if what you changed has made any difference. Just be logical about it.

I also have a wireless network adapter on my desktop so tried to connect using the wifi. Now this connects to the unidentified network (plusnetwireless) but gives local only.
I literally have no clue what to do now as the ethernet connection on the desktop will not connect and neither will the wireless adapter.
Help!!!!!!!!

I'll try your suggestion of deleting the network adapter and rebooting. The drivers are on the pc as I tried to update them and it searched and said they are already installed to the latest version.
