Few days ago Toshiba service station recommended me to upgrade BIOS to 1.70 (i had 1.50). After this upgrade my WLAN adapter not working yet. Sometimes it's work 5 minutes after laptop start, sometimes more than hour.
Does anyone have any ideas how to install previous version of BIOS?
I know where to get BIOS... I did install wlan drivers few times on different OS and same problem on both. Question is " How to downgrade BIOS". Motherboard dont want install current or previous version... only newest one.
