I've got an Airport network running off two Airport Express devices in my home. My Mac machine finds it perfectly but my Windows laptop can't connect to the Internet - it connects to the wireless network seemingly without a problem, but then can't connect to the Internet. Any ideas?

Umm I will try to explain as I use a dlink G650 quite often.\n\n\nYou should have a box that is under the properties of your network card or it might be under the protocol thing and it has a list of your prefered networks and which one to auto connect to.\n\nBetter still double click on the icon for your wireless network connection then go to properties once you get to the windows thing go to the tab for wireless networks there is an option in there just do wht you need to

Make sure the SSID names are the same on both computers... like WORKGROUP is what it usually defaults too. I have had problems before and loading the IPX protocol has taken care of those. Hope this helps If you are using wireless, make the SSID the same name as your Router.

The problem isn't with your computer but with your Wireless router. Your Windows firewall is probably working just fine.\n\nYou need to log in to your wireless router, create a unique SSID (located on the router), and configure security. It'll ask for a pass phrase. Save the phrase or the converted hex string and the SSID. Then you'll need to configure it into your Windows system. Check the Wireless properties.\n\nYou might also get your MAC address from the windows box (Start, Run, Cmd. In the command window, type ipconfig /all. One of the items is your Mac address. Save that.) On the router, you should be able to restrict access to the router by specific MAC. Activate that and enter your MAC.\n\nOnce that's all done, your wireless router should be reasonably secure.\n\nThis site should have expanded answers that might help if what I said above isn't as clear as I'd like it to be.\n\nhttp://www.practicallynetworked.com/support/wireless_secure.htm

It sounds as though somebody's getting a "free ride" on your network...  if the building is shared, or adjoins other buildings, you may find somebody tapped into the cabling or your router...\n\nFirst, go and look at the router itself..  how many connections?  If there's more ports in use than there should be, unhook them one at a time...  if there's one that you can unplug without any of your computers going offline...  start tracing that cable..\n\nFailing that, you'll need to go into the admin pages on your router...  the first thing to do is to change the router management password, so that your "guests" can't undo your changes.  Now take a look and see who's connected.\nIf there are IP numbers that don't match any of your computers, that's a clue...\n\nJust blocking out those IP's will give you a temporary diagnostic...  as above, if there's one that you can shut off without losing your own connections, there's your problem.\nLong-term, that's not a good solution...  you'll need to get the MAC address for each of your computers, and then set up "MAC filtering" on the router, so that only your machines are permitted access.\n\nOnce you've identified the "rogue" connection, you can either just leave it dangling, or cut the connector off and twist all the wires together ... think of the hours of fun they'll have trying to sort that out...

If you want to connect to you WiFi at home: \nTry to connect with a LAN Cable to your WLAN Router and reset the passwords for the Wireless LAN.\nThen re-enter the password in the router and the Laptop.

Your router needs looking at. Below is a URL for you to check out.\n\nThere is also another to a tech forum where they help with networking issues.

Wireless routers only accept external Internet connections from a hard LAN. They do not accept the incoming communication wirelessly. A wireless router will work without an Internet connection to create an internal home network, but will not have Internet access. Now you can buy a wireless LAN card for your laptop and if there are unsecured wireless networks within range you can get on the Internet by piggybacking on their signal. However, unless this a publicly open connection it will be considered stealing bandwidth.

Things to check for:\n1. Is the wireless access point connected to your router (unless the access point and the router are in the same unit)?\n2. Do both computers have valid IP addresses (and valid network masks and gateway addresses)?  These must either be set by hand, or else you set the computers for DHCP (but that only works if either the router or your ISP is providing the DHCP service -- to make the router offer DHCP service you would have to turn on "NAT" in the router).\n3. Can each computer ping the other?

Some of the answer to this questions depends on the operating system you are trying to connect with. Windows XP makes connecting very easy. \n\nFor you to be able to access the internet via a wireless connection, you will need to have a wireless card for your laptop.\n\nAssuming you have the card, you need a wireless router to connect it to. This might be your router, your neighbors router, or it could be the router at that internet cafe down the street.\n\nTo connect, you need to know at least one piece of information and that is the SSID of the router you are connecting. If you have Windows XP, you can click on the button to "View available networks" and it will list them for you. Many of them are going to say they are "security-enabled" networks, which means you need more information to connect. If you see any that are listed as "unsecure" you can connect to them without any more information. Be careful doing that because in some cases you can put yourself at risk doing it.\n\nIf you want to connect to a "security-enabled" router then you will need to have the encryption key for that router. If it's your router, you would have that information, otherwise you need to get it from the owner of the router. \n\nThere are more security features that routers might have, like MAC address filtering, client controls, and more. \n\nHope this helps.

What you have is an ADSL Gateway router! It is a wonderful device which will have multiple ethernet ports, DSL port and 1 or 2 wireless antennas. Here is the connection diagram:\n\nLAN Side: Within your home\nEthernet 1: PC1(use this to configure your router if needed)\nEthernet 2: PC2 (if any non wireless)\nEthernet 3: PC3 (if any non wireless)\nEthernet 4: PC4 (if any non wireless)\nWireless: to as many laptops that have an 802.11g wireless PCI/USB adapters\n\nWAN Side: from your home to internet\nDSL port (WAN): directly to a phone line.\n\nThe internet is accessed via the DSL line and information is routed into your home gateway which then bridges data to individual PCs.\n\nYou use ethernet to connect desktops or a laptop with which you wish to configure your router. Otherwise laptop is best connected via wireless. Check the wireless connection that your laptop is connected to and that it is yours and not a neighbors!

Make sure that you have typed in the correct MAC address for each routers. If the other 2 are already set as an access point it still needs to have the correct MAC address of the routers that is on the network.try also disabling the WEP/WPA on the routers or might as well just use the 64bit WEP because sometimes it would affect the connectivity. Its much easier if you to test with the 2 routers first having one set as an access point, from there if everything is ok, then configure the other one.

Your WEP key needs to match that being broadcast from your access point/router.  Once it's entered correctly on your apple, it should connect.  Make sure you have the right WEP key set up in the airport settings.

You could have a hitchhiker or two. Did you set up a firewall and either WEP or WPA? If good security doesn't discourage hitch hiking, try setting your router filters up to recognize ONLY the MAC addresses of the equipment you have in your LAN.

You probably have cable internet. \n\nIn the settings for the router you have to setup MAC address cloning. I can't remember off the top of my head where it is in the settings. You have to setup it up so the router takes on the mac address of the PC the cable modem was originally attached to when the service was established. After that, the problem should go away.

You should have a sticker that says WIFI on the laptop if it does.  Usually laptops have a button to turn WIFI on or off.  Sometimes you don't want to autoconnect if your unsure of the network.\n\nIf your connecting at home you will need a wireless router.   If you want to connect to hotspots you may have to pay a fee either monthly.\n\nGood luck

It is because your computer is unable to get an IP address from the DHCP server, which is part of the router.\n\nI think you are in a home environment so here is the way; \ncheck your wireless router and try connecting it through ethernet cable. If the device seems to be fine then look for devices like microwaves, cordless phones and other devices which share the 2.4Ghz frequency range because they interfere in your wireless connection. If the device is not connecting even with the ethernet cable then try resetting your router.\n\nIf all fails, my friend, you need to maybe get it thouroughly checked by somebody who has knowledge.
