Connecting pc directly to router, router to modem and having access via lap

By ajk1615 ·
Hi All,

I have a confusing question.

I have a cable modem connected to a Belkin router. This router shows the connection fine and I am able to wirelessly connect via my laptop, gaming systems, etc.

However, when I connect the same router to a pc via a usb cable....it stops functioning for the laptop. At that point I can connect to the internet on the pc...but not via the laptop.

amy thoughts?

I guess, to put it more clearly, what I am trying to do is connect the pc directly to the modem via a usb cable.

AND the same modem to a wireless router for use on a laptop.

If I hook them both up - one of them stops working. If I do just the usb to modem...works for the pc. If I do just the modem to router - works for laptop.

I just can't do both at the same time.

Can't do that...

Well, for starters, what you want to do won't work.

You are given one public IP address (static or dynamic) from your ISP. Whatever you plug into that modem is going to get the IP address. If you plug a router into it, the router has DHCP functionality, meaning it will hand out private IP addressed to all workstations you connect to the router. If you plug a workstation to that modem, it's going to take that 1 IP address.

Wouldn't it just be simpler to connect both computers to the router? I am assuming of course that you have a router/switch combo (which most consumer products are) and not a just a router.

Problem is with my ethernet

by ajk1615 In reply to Can't do that...

I think I do...but I have to connect the pc to the router via the ethernet card.

I had to reinstall my operating software and when I did somehow my drivers disappeared. So I have an ehternet card...and the port and all that - but no driver. I can't even tell what kind of driver I need to download to get it to work.

So, I can't connect the pc to the router because that's the only way to do it. Unless, I buy a wireless thingamabob to connect to the router that way.

Is it a name brand

by IC-IT In reply to Problem is with my ethern ...

Desktop or a custom build?
If it is a name brand you can go to the manufacturer's site and download the drivers for your NIC.

Belarc advisor, Aida32, or a few other free programs may ID the card for you.

Most Likely

by Brenton Keegan In reply to Problem is with my ethern ...

You rebuilt your computer, not just reinstalled the OS. By rebuilt, I mean formatted the drive and all that jazz.

It's likely that the network adapter drivers aren't the only thing you are missing. Right click on my computer and select Manage. Then find Device Manager and look for any yellow question marks. Those are devices that don't have the drivers they need.

As someone else said, your manufacturer should have the drivers. I would recommend getting the drivers from the computer manufacturer. Even though they may be made by Intel or whoever, sometimes they are slightly modified from the hardware manufacturer's original.
