MY COMPUTER WONT STAY CONNECTED TO THE INTERNET VIA WIIFI

Hi STABU2,

There are various possible reasons for intermittent wireless connectivity. Please try the following steps:

1. Ensure that maximum distance between the laptop and router is less than 30 feet. Place the laptop very close to the router and check if that makes any difference

2. Check if you can connect to any other available network. An unsecured connection has a yellow mark besides it. (It does not ask for a network security key). If the wireless works fine with another network, your router settings may have to be changed. Else, try changing the 'wireless card' settings.

3. Maximize the performance of 'Wireless Card' installed in the laptop:
Note: Different wireless cards are shipped with Dell laptops. Please use the following steps to access and change card settings:
- Right-click the 'Computer' icon on the desktop or from the 'Start menu'
- Click 'Manage'
- Click 'Device Manager'
- Click the + sign to expand the 'Network Adapters' entry
- Right-click the wireless adapter (Dell wireless 1395) and click 'Properties''
- Click the 'Advanced' tab to configure the advanced settings
- Select Power Management, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.
Note: If the slider is already at Highest / Maximum Performance, move the slider to another setting and then back to Highest / Maximum Performance.

Change the following settings in the Dell Wireless card:
- Bluetooth Collaboration is set as 'Enabled' by default. Please 'Disable' it.
- Set value of 'Roam Tendency' as 'Aggressive'
- Save the settings and re-check wireless performance

If you still experience issues, please set the wireless card settings to the following values (These are the recommended card settings for some Comcast modems':
- Change 802.11h+d to 'Strict 11h'
- Change Afterburner to 'Enabled'
- Change Antenna Diversity to 'Main'
- Change AP Compatibility Mode to 'Broader Compatibility'
- Change BSS Mode to '802.11g Mode'
- Change BT-AMP to 'Enabled'
- Change Fragmentation Threshold to '2300'
- Change Locally Administered MAC Address to '1234567890AB'
- Change Minimum Power Consumption to 'Disabled'
- Change PLCP Header to 'Long'
- Change Roaming Decision to 'Optimize Distance'
- Change RTS Threshold to '2300'
