Laptop has re-installed Intel/ProSet Wireless Adapter, worked perfectly at college for over a year using there hot spots, recently re-installed the operating system and the software for Intel, now when trying to click "wireless on" a message appears, saying "the wireless network connection is disabled, use you hardware switch to enable it"; the laptop has no external "switch" to toggle between on and off, the whole process is done by a dialogue box on screen.
Thanks Graham, done all that, no effect whatsoever. Covered all that area etc. Re-installed the wireless adaptor as well, nothing works. Sometimes there is an external switch on the laptop..... mine has nothing!
