Do I need a new router?

AuntyJean

Hi,

I have just moved to a flat and had Virgin Media including broadband at my previous address with a modem which had an ethernet cable. They drilled a hole in the wall adjacent to my pc (a recess in the bedroom) and fed the cable from there to my computer. Setting up wireless network was relatively simple with your guys help.

In the flat I also have Virgin Media broadband but the modem they supplied was a different model. In addition, it does not have an additional ethernet cable and, it is situated in the lounge as that is where the cable connectors are. I ran the ethernet cable to my pc but do not know how to connect up the router.

The PC is in another room about 30 feet away (if you run cables over doorways and along skirting boards) so do not want to run the co-ax along this route if avoidable.

I have a Scientific Atlanta 2100 modem with what looks like a USB port (but square, not flat) and a Belkin F5D7231 (4) router.

The only spec I can find with regard to any network connections on the pc are

1394 Net Adapter
Intel(R) PRO/100 VE Network Connection

I also have a laptop with an external network g card (built in is a network b I think).

Is it possible to set up networking on say the laptop and instert the network card into my pc to make them talk to eachother or will I need to buy a different router? Or, can I conect the router to the modem wirelessly or will I have to run cables?

The Ethernet port is next to the power connector,

If you are using a router that plugs into the modem and then run your PC off one of its ports.

Yes, the ethernet used is the one that connects to my pc. I need an additional one that connects from my router to the modem. The old modem had two ports. Plus modem in lounge, pc in another room.

It's a little difficult to visualise what you are trying to do, but if you're simply trying to link the Belkin router to the modem, and then link everything else into the router, that should be no problem.

However, connecting the modem to the router would normally require an Ethernet crossover cable (these are easy to buy) unless the router has one Ethernet port marked "uplink" or similar, or it has auto-detect for uplinks.

Incidentally, the USB port on the modem is just a "Type B" layout and... don't be tempted to try and use both the ethernet and the USB at the same time - it usually doesn't work on this type of modem (I found this out the hard way!)

Previously, the router was connected to the modem by way of an ethernet cable. the router was also connected to the pc.

This modem has only one ethernet cable and that is connected into the back of the pc. Are you saying that all I need to do is connect it to the router instead of the pc?

Sorry but it was 2 years ago since I set it up and I labelled all the cables as to where they should go and was simply trying to do the same set up as before!

Yes - but you may need a crossover cable, because the ethernet socket in a hub/modem/router is wired as a (almost) mirror image of the one in a PC/laptop. However, some have hardware that can detect and work around this.

The PC can then just plug into one of the 3 remaining sockets in the router.

I simply did as suggested, plugged the ethernet cable from the modem into the router instead of the PC then the other ethernet cable from the router into the PC. Thought at first it would not work but followed the network wizard and ..... hey presto!!!!!

It's all up and running again. Thank you.
