How do wired and wireless connections to a home router work?I have a question about using the wireless capabilities of my wired/wireless LAN. Normally, I use the wired connections to my home router for all my networking needs. Sometimes, when watching the TV, I like to surf the web at the same time using my laptop's wireless connection. To do this, I first enable my router's wireless access and then enable my laptop's wireless connection. It all work very well, but I have some questions, just to fill in my knowledge gaps. - If I leave the wireless connection enabled, and reattach the laptop to the wired LAN, how does the laptop know which connection - wired or wireless - to use. I assume that the two modems have separate metrics configured, but I haven't been able to find where. - If I switch off the laptop's wireless modem, but leave the router's wireless access enabled, is all LAN traffic on the wired LAN segment also broadcast onto the wireless LAN segment? Is the router's wired and wireless accesses considered to be across two separate LAN segments? I assume not, since the wireless connection gets its IP address from the router from the same address range as the wired connection. - If I bridge the wired and wireless connections together, what does this mean in the case, where both connections are accessing the same LAN? I've been searching the web for answers to these questions. Lots of tutorials about setting up a home network, but no information about these more detailed topics. Can anyone help, or point me to somewhere I can learn mor about this stuff. Many thanks, Paul Hi
1. You can easily create a setting that would decide what the preference is if the connections are available. Here how, http://www.ezlan.net/metrics.html. 2. If the Wireless is On and No computer is actively using it nothing is taken from the Internet Bandwidth “Speed”. I.e. even if the laptop is On and connected to the Wireless it does not take any thing of the system if you are not doing anything Network related. Make sure that your Wireless is secure so other people cannot log into it. Wireless Security - http://www.ezlan.net/Wireless_Security.html 3. The wire and the wireless are connected together inside the Router. Many computers can use both the wire and the wireless at the same time. All the computers that are using the same Wireless Router (wire or Wireless) are connected to the same LAN. Since they are sharing one Internet connection while they are using the Internet the Bandwidth (“Speed” ) would be split between them. To actually exchange info between the computers (wire or wireless does not matter) you have to configure on each computer the File Sharing.

Thanks for the replies, Jack and James.
For point 2: Does that mean that activity across the wired LAN is also broadcast on the wireless section of the LAN, even if no PC is connected to it? I have two more questions. 4. At work, I can access two separate LANs from my laptop. The corporate LAN 130.x.x.x is accessed with the wired LAN connection, and a separate test LAN 192.168.x.x is accessed with the wireless LAN connection. If I ping a node on the 192.x.x.x LAN either from a Cmd window or from Cygwin, how does Windows know which connection to use? 5. If I bridge the two connections, what will happen? I suppose it shouldn't work, since the IP address ranges on the two LAN segemnts are different?

Broadcast is No the correct term. In the Router the Internet Signal comes internally out of the Routing circuits and it connected to both the Switch (Wire connections) and the Wireless Access Point. I.a. as long as the Wireless part of the Router is On the signal is there been ready to be used. The only thing that a an Access Point Broadcasts when it is idling is its ID name (SSID), those are the name that you see in the Wireless Connection Windows when you choose a connection. When an external computer choose to connect to the SSID and the traffic starts to flow the Internet signal is available to be used. I.e. the water is Not flowing all the time they flow when you open the faucet. ;) Jack (MS, MVP-Networking) Show quoteHide quote "Paul Moore" <pauldotmo***@pandora.be> wrote in message news:TL%jl.617$ci1.546@newsfe13.ams2... > Thanks for the replies, Jack and James. > > For point 2: Does that mean that activity across the wired LAN is also > broadcast on the wireless section of the LAN, even if no PC is connected > to it? > > I have two more questions. > > 4.

There is nothing to stop you routing packets between the two interfaces to put your other wireless workstations on the Internet via the wired connection (or whatever) but bridging isn't the way to do it. Jim. Jack and James, thanks again.
