How to Increase the Reception of a Wireless PCI Adapterby Ruri Ranbe
To communicate with a wireless network, a computer needs a wireless local area network card, also called a WLAN adapter. This adapter connects to a mini-PCI slot on the motherboard. Two antenna cables attach to the card, and these cables send and receive radio signals, allowing the computer to interface with Wi-Fi devices. If your computer fails to find or remain connected to local wireless networks because of poor signal strength, you can adjust the settings on the WLAN adapter to improve reception.
Click "Start" and select "Control Panel." Type "network" into the search field and then click "View Network Connections."
Double-click "Wireless Network Connection," and then click "Properties."
Click the "Configure" button and select the "Advanced" tab.
Select "Roaming Sensitivity Level," "Roaming Aggressiveness," "Roam Tendency" or a similar option.
Choose "High," "Highest" or "Aggressive" from the associated drop-down menu.
Click "Transmit Power" or "Transmit Power Level," then select "Highest" from the drop-down menu.
Select "Antenna Diversity" and confirm that the option is set to "Auto." Click "Band Preference" and choose "Prefer 802.11a" if your wireless network uses the 5 GHz band; choose "Prefer 802.11g/b" if the network uses the 2.4 GHz band.
Click "OK" and "Close" to improve the wireless reception on the network adapter.
- If you experience connectivity issues after setting roaming aggression to high, reduce the value to medium for improved performance.
- Not all wireless adapters support the options above. Settings and options vary, depending on the make and model of the device.
