Hi DavidCo90,

The issue is with the incompatible settings of wireless card with the wireless network. Please follow the steps mentioned below.

First of all uninstall the wireless card drivers from your system and update the latest wireless card drivers for your system from the support website : support.dell.com and reboot the computer.

• Press 'Windows'+ 'X' key combination on keyboard.  
• Click on Device Manager from the menu that pops up from the bottom left corner of the screen.
• Expand Network Adapters, right click the wireless card and choose Properties

Make the following changes

• 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 (This step is important)
• Change Minimum Power Consumption to Disabled
• Change PLCP Header to Long
• Change Roam Tendency to Aggressive
• Change Roaming Decision to Optimize Distance
• Change RTS Threshold to 2300

Click the Power Management tab

• Uncheck Allow the computer to turn off this device to save power

Also Open Power Options from the control panel -> Hardware and Sound

• Click Change plan settings for the selected power profile
• Click Change advanced power settings
• Under Wireless Adapter Settings , click Power Saving Mode and change the settings to Maximum Performance

The problem is that when you do this: Change Locally Administered MAC Address to 1234567890AB

It will disable SoftAP feature....

What about Windows 7 system and losing network connection - same process?
