    I have a modem which has USB 2 port. I was using it directly in my laptop by installing driver. But now I want to use wireless connection. So I bought a router but now how can I use my existing modem with this router? My ADSL modem has USB type b female port. Is there a cable that one end has USB type B male jack and other end RJ 45 jack? If so how about the modem driver? I have no clear idea will this work or not. OS is windows 8

    Thanks

    Usually when the modem only provides an USB connection, the authentication is made by the computer using PPPoA or PPPoE.

    The modem only acts as a transport layer, however, you need a specific driver to talk to your modem. There is no way a bare router could do this, you absolutely want a computer to act as a router in this case.

    You should have brought a DSL router which would allows you to authenticate to your provider or at least have an Ethernet access on both sides.

    I currently own an ADSL modem. I am planning to buy a D-Link DIR 600 Wireless Router, for setting up a wireless network to play Counter Strike with my buddies. I have a few questions.

    1. How do I set up the router? Am I correct in thinking that I should connect my telephone wire to my modem, my modem to my router, and then my router to my PC?

    2. If I switch on WiFi on the router and let my friends connect to the network to play CS, will the game be actually be played locally or through the internet?

    3. How do I set up only LAN-sharing, without internet? Is it easy to switch between LAN-only sharing and traditional internet sharing?

    EDIT : My ADSL modem is also a router, but it has only 1 ethernet port, which is currently connected to my PC. So I will be connecting my wireless router to my ADSL modem/router.

    To add to question #3:

    After I finish playing CS, I want to be able to continue using the internet on my PC, after switching off WiFi; i.e., stopping my router from beaming my internet connection. How do I do that?

    The existing ADSL router is all you need to connect to the internet. Adding a second router is both pointless and expensive. A cheap cable router of the type you are looking at will not work with your ADSL router.

    What you require is a small (maybe 4 of 5 port) switch to increase the number of ethernet ports available on the existing router, and a wireless access point to share the network out as and when you want it.

    Sample Network

    When you want to disable all access to the network through wireless means you can just unplug or turn off the wireless access point.

    1. If your router is a ADSL-modem/router, you can get the ADSL modem out and just connect the router (you'll need to know the ADSL configuration of your ISP : protocols + credentials). But else your are right. The router will get the public IP from the modem and dispatch to the other networks (Affecting an IP to each if DHCP is active).

    2. If your friends connects to the wireless and your are playing a game, it will be on LAN if the server is on the LAN and you connect to it via a local address (192.168.x.x for example), but if the server is online, it would of course, be through internet. Undefined behaviour if you join a game from a list on the internet and it "fortunately" ends being a server hosted locally : would depend on the games I guess.

    3. You can just disconnect the router from the modem, or maybe the router has an option to close a port. Then all traffic can only go between peers. Be advise that LAN-Sharing for file etc may have to be enabled on the OSes. For games, it's generally not a problem since it's just networking stuff. Then if the hosts can pings that should be ok (!!Firewalls!!)
