windows xp - WiFi: Internet doesn't work, local network does

  • noober

    I have a problem with the Internet connection thru WiFi.

    Some time ago I had reinstalled OS (XP Sp3) on a notebook (Samsung R560 with a WLAN adapter that's specified as 'Intel 802.11a/b/g/n 1x2 (MIMO) / Intel 802.11a/b/g/n 3x3 (MIMO) / Atheros 802.11b/g'). Then (I understand that 'then' doesn't mean 'therefore') I faced the following problem: I could access to local network, but not to the Internet.

    ISP's broadband Internet cable is connected to WiFi router ASUS WL-500, having local IP address (DHCP is disabled). Both 2 and 3 are assigned to a Windows server and another notebook. is assigned to the Samsung notebook. I had installed a custom Intel utility on top of the WLAN driver, then (after the problems begin) uninstalled it, so now I have the naked driver.

    From time to time, the Internet connection gets broken: no external sites are available, Skype is out, Outlook can't get e-mails. Nevertheless, I still have access to the local network, say, \\c$. The other machines are still connected to the Internet thru the same router.

    What can be the problem root? What have I look at?

    Sounds like you've got the IP address; but you need a default gateway and a DNS server IP configured on the laptop as well. The default gateway is the router (sounds like and you can use any available DNS (like or

    Turn off energy-saving mode for the WiFi adapter, it's often buggy.

    windows xp - How can I connect my XP laptop to my wireless network if my wireless network doesn't show up in the list?
  • classer

    The Problem

    For some reason my XP laptop can not see my wireless network but my Vista laptop can see it fine. I should also say that my XP laptop can see all my neighbors' wireless networks just fine.

    My Questions

    • How come my XP laptop does not see my wireless connection?
    • Do I have to manually add my wireless network to the list?
    • If so, why? Why can it see all my neighbor's wireless networks but mine?
    • How can I connect my XP to my wireless network?

    UPDATE I thought it would be a good idea to post more details about my setup:

    • Gateway

      In this mode, the device is supposed to connect to internet via ADSL/Cable Modem. The NAT is enabled and PCs in LAN ports share the same IP to ISP through WAN port. The connection type can be setup in WAN page by using PPPOE, DHCP client, PPTP client or static IP.static IP.

    Other unselected operation modes are:

    • Bridgeclient, PPTP client or static IP.

      In this mode, all ethernet ports and wireless interface are bridged together and NAT function is disabled. All the WAN related function and firewall are not supported.

    • Wireless ISP

      In this mode, all ethernet ports are bridged together and the wireless client will connect to ISP access point. The NAT is enabled and PCs in ethernet ports share the same IP to ISP through wireless LAN. You must set the wireless to client mode first and connect to the ISP AP in Site-Survey page. The connection type can be setup in WAN page by using PPPOE, DHCP client, PPTP client or static IP.

    Manually Added Wireless Network: Rilos
    I access this information by going:

    You say that the laptop is Windows XP, this can be up to/around 10 years old.

    My guess would be that the wireless network is being broadcast in a band or mode (a/b/g/n) that the wireless card in your laptop does not understand.

    If however it does understand, my best bet and advised solution would be to manually assign/setup the profile and see if it will connect as sometimes this can work.

    Go to the list of preferred networks (Network connections, right click wireless, go to the wireless networks tab), and type the details.

    On which channel is your WIFI? Depending on your location (the driver settings), your two WIFI cards might not be able to use the same channels.

    For example: If your accesspoint uses channel 13 (not allowed in the US but in Europe) and your Vista laptop's driver is set to Europe it can connect. If your XP laptop's driver is set to US or similar then it won't even look if there might be a network on channel 13.

    Sidenote: If your accesspoint is set to "auto" + "use all channels" this can give you real headache for troubleshooting a sometimes working and sometimes invisible network.

    The capabilities of your driver sometimes can be seen/changed in the Windows devicemanager (devmgmt.msc). Sometimes you get different drivers depending on whether you download it form the manufacturer's US-website or the Europe-website. To be safe, set your accesspoint to the lowest common denominator and only use channels 1-11.

    List of allowed channels per region:

    • US: 1 - 11
    • EU: 1 - 13
    • Japan: 1 - 14


  • Mike Chess

    Try changing the channel on you AP. Use something like channel 3 or 5. That may help the XP laptop pickup the AP.

    The wireless connection management tools in Windows XP are not great. I've been using Avanquest Connection Manager, free software that takes over the task from Windows. The freeware InSSIDer is also helpful for visualizing and diagnosing wireless networks. There are a few possible explanations for what's going on, as already described by others here, but I recommend starting off by installing those two tools so you can effectively remove the blinders being imposed upon you by Windows.
