PC Troubleshooting Wireless Network 802.11B

How to troubleshoot a Wireless Network 802.11B

  • What type of connection - Access Point/Infrastructure or computer-to-computer/Ad Hoc ?

  • What is the Network Name(SSID) set to ? using encryption?

  • What access point/cards are being used?

  • Did it ever work ? Do we see the Wireless Configuration Utility icon on the taskbar?

  • Is there a Wireless Connection icon in the Network Connections folder? can we view the properties?

  • Is the adapter being assigned an IP address? can we ping the address?

  • If subnet mask= 255.255.0.0 release & renew, reboot access point

  • Look in the Network Connections for a Network Bridge, unless the user is connecting to two access points, it should NOT be in there.

  • Is there interference from 2.4 Ghz phones or microwaves? Is it set up as roaming(more than 1 access point)?

  • Follow These Procedures To Fix 802.11B or 802.11G Problems:

    1. Reinstall the existing drivers and software
      • Uninstall all network adapters in Device Manager
      • Delete the Network Bridge in the Network Connections folder
      • Uninstall "Wireless LAN software" from the Add/Remove Programs in the Control Panel
      • Shut down and restart, do NOT go through the Network Setup Wizard when XP redetects the NIC's.
      • Run the setup program for your Wireless Lan software e.g. C:\hp\Drivers\Wireless\setup
      • We should now have the Wireless Configuration Utility / 802.11 connection icon on the taskbar
    2. Go through configuration settings

      • SSID should be "ANY" or same as the Access Point
      • Data Encryption (WEP) should be unchecked (on AP as well)
      • Network Authentication should be unchecked
      • Computer to computer should be unchecked if we are using an Access Point click on the OK - if it says it is already configured, use Properties Button click on the Advanced button on the Wireless Networks tab, set to "ANY", Close
      • Click on the General tab, highlight the 802.11 adapter and click the Configure button
      • On the Advanced tab, adjust the settings for the connection
