Creating a wireless access point
in [Network and Web]
|
From: MR EDDD on 21 Mar 2010 03:25 Hey, Basically I'm trying to work out how to set up a wireless access point on my laptop. My laptop is on a wireless home network and I want to set up a mini open network. I have been planning on using a USB wireless dongle which can be used to create an access point and put the dongle in my laptop. There is already a wireless network card in the laptop and I seem to be having issues with either the access point working or the wireless working but not both and I couldn't get the access point to access the internet (via the wireless card). I tried using both the software that came with the dongle and the windows network connection tools (to no avail). If anyone could give me a bit of assistance with this it would be greatly appreciated. -- cheers

I assume that this is what you are attempting to do: (a) have the laptop access the Internet using its built-in wireless card to connect to your existing wireless router and (b) have other computers access the Internet via a wireless connection first to your laptop and then a second wireless connection from the laptop to your router. Because those other wireless computers could simply get to the Internet by connecting to your wireless router, I assume that what you're attempting to accomplish is separate these other computers from your existing LAN. There are at least two better ways to do that. If you don't care about letting *any* wireless computer on your LAN talk to any other device on your LAN (i.e., just get to the Internet), you could turn on your router's "AP Isolation" feature. Here's what Linksys says about that: "Creates a separate virtual network for your wireless network. When this feature is enabled, each of your wireless clients will be in its own virtual network and will not be able to communicate with each other. You may want to utilize this feature if you have many guests that frequent your wireless network." If your router doesn't have "AP Isolation," or if you just want to isolate the "other computers" but have your own wireless computers share files and printers, use a second wireless router. This has the advantage that you won't have to leave the laptop on. See, e.g., http://ezlan.net/shield.html However, to do it your way, see: http://support.microsoft.com/kb/306126 http://support.microsoft.com/kb/314066/en-us http://www.practicallynetworked.com/sharing/xp_ics/ And make sure to set the USB wireless adapter to use a different wireless channel than the one your router uses (I suggest using channels 1 and 11) -- Lem Apollo 11 - 40 years ago: http://www.nasa.gov/mission_pages/apollo/40th/index.html
