I have a issue with a Toshiba Sat Pro A300 and it Realtek WLAN network card... I have read through the old post re WLAN issues and nothing I do will fix the issue... basically if the firewall is enabled the WLAN will not transmit any traffic to or from the network... it will not even allow it to gain a DHCP address? If I completely disable it the WLAN card springs back into life!... I noticed someone has put that version 4.2.71 fixed his issue but that version doesn't even exist with 4.2.67 being the latest to download. Please help.
