Latitude E6400 is a good laptop that comes with the Intel Wifi Link
5300 AGN as the network connection. About this WiFi, someone has a
trouble; suddenly his Wifi Link 5300 AGN adapter continually drops
wireless connections to his home Linksys WRT300N access point and
router. He could connect without a problem when the encryption is
disabled, but when re-enabled encryption he would either connect at
1Mbps or not at all.
To make the Latitude E6400 that dropped it connection to home wireless
going back normally work, here’s the way you can try to do:
Download the latest driver from Intel’s site
Uninstall Intel utility and let Windows manage wireless connections.
Reset the router back to factory default.
Made one change at a time to see what caused loss of connection
Make sure that the encryption was set in the right level
Set the radio band back to Auto
Changed the encryption algorithm from AES to TKIP
Change three settings in the wireless cards driver as well. Go to the
Advanced tab of the wireless card driver and make the following
changes:
- Power Management – Highest,
- Roaming Aggressiveness – Lowest,
- Power Saver Mode – Off.
Finally, on the power management tab, disable power management.
