I have a Satallite L450-181 and have had to install a new hard drive with a fresh install of windows 7 professional.
Everything is working apart from the wireless device when I install the driver the device disapears I can find it using msinfo32 and it appears it has no ID and when it has shown in device manager its shows error code 12 "no resources".
The device is a realtek 8191se nic.
I have tried various drivers but none have worked I have searched loads of forums for similar errors and none have actually been the same problem as i have the wireless switch enabled. after the driver is installed for some reason it disconnects and i am unable to reconnect it.
Has anyone had this problem and found a solution to it as it is driving me mad?
I installed the WLAN driver last after installing everything else. I have tried various orders of install outcome is always the same soon as the driver is installed the network adapter goes missing and shows as diconnected.
Please try this:
Go to BIOS (press F2 while booting) and set the BIOS to default (F9) then save the changes (F10) and reboot.
Then download the right Wlan driver from Toshiba WLan portal: http://aps2.toshiba-tro.de/wlan/
Install the Wlan driver and check if the Wlan card is recognized properly in device manager.
Usually the Wlan could be switched on using the FN + F8 keys.
The FN buttons would work if you would install the VAP and Flash Card Support Utility. Note. The VAP needs to be installed at first.
I use both tools released for Sat L550D series… both work on my old A210 and I can enable and disable Wlan properly.
I have tried that and still no joy.
The wlan device shows at network controler before i install driver once installed it disapears. What i can work out so far is the device is not been allocated any memory resource or an IRQ as it shows in the log from "msinfo32.exe"
