Rj45 /usb wireless connections

Specs: Windows Vista

Hi,

I have a mobily wireless modem which has two outputs. 1 USB (small plug) and 1 RJ45 ethernet connected to my satellite tv box.
Currently I connect my laptop to the modem using the usb cable. I would like to purchase a wireless router but want to know if I can connect to a wireless router using just my usb cable?
Or do I have to buy a USB to ethernet converter (RJ45) and then buy a wireless router that has a wan port for ethernet rj45 too? please help as I am pretty confused!

Generally speaking, your setup should look as follows:

highspeed modem >> SOHO router >> clients

Now regardless of which your highspeed modem is (ie: DSL, cable, wireless, satellite) it should have an RJ-45 connector which you use to connect to your SOHO router or a client PC.

The SOHO router will have RJ-45 connectors as well. One external (interner) port and 1 to 4 LAN (local area network) ports. The LAN ports of course are for the client connections.

So as I said above, you should connect the modem to the "Internet" port of the SOHO router with a network patch cable. Then plug your client(s) into the LAN port(s) on the SOHO router. If you buy a wireless SOHO router, you can also connect wireless clients.

Thanks for this- the problem is I can disconnect my satellite connection from the router as it doesn;t work via a router. So, I think you're saying I need to connect to a SOHO router using a USB to RJ45 converter and then connect to any other client using the other ports? Have I understood your correctly?

Correction- I can't disconnect my satellite from the modem which is where the rj45 connection is being used up. Leaving only the usb port free to use if I want to get internet connection on a laptop.

Ahhh ok, gotchya!

When you first said, "I have a mobily wireless modem which has two outputs. 1 USB (small plug) and 1 RJ45 ethernet connected to my satellite tv box. " I thought you mean two outputs one each of USB and RJ-45. What you mean was, the RJ-45 is an 'input' and the USB is the 'output'. This is different from two outputs one each USB/RJ-45. Thus my confusion.

Usually with cable/DLS modems you have your cable/phone connection coming into them and an RJ-45 out to your SOHO router.

This is a different device.

Since you are restricted to a USB port going out of the modem, that's what you'll have to use......a USB to RJ-45 adapter. Then you plug the USB end into the modem, and the RJ-45 end into a SOHO router's 'external/internet' port to make it work properly.
