(I'm posting in a Ubuntu forum because A) Before I switched to Mint, my Ubuntu 10.12 had the same problem. B) The systems are so similar -- one derived from the other -- that the solution for one should work for the other. C) Ubuntu forums are the only ones on which I've found usable advice. You guys have the better support, and I believe the system diff will not affect anything. D) I plan to switch back to Ubuntu when and if they lose Unity Desktop).
Hello. I'm a bit new at Linux, and after installing Mint 14 on my laptop, I am unable to use the wireless. I have gone through every forum I could find; each of their answers revealed a problem I had not noticed, and helped me to correct it: Network Manager had kept my WiFi Disabled, the correct module (rtl8187se) was not present (similarly-named and useless ones took its place), and ndiswrapper was faulty, as were its updates and patches. And so here I am. My problem at the moment is my card's inability to detect wifi networks. All the drivers seem to be in working order, the card functions in Windows 7 (which I dual-boot), and currently picks up three high-strength networks nearby. In Linux, the card is recognized, Wifi is "On", Airplane mode "Off", but recieves nothing. I've tried to be as thourough as possible, listing everything that might be important. Anything you guys could do would be greatly appreciated. Thanks! (The Fn-F8 key combo is marked on my keyboard, but does nothing, even in Windows).
Toshiba Sattelite L455D-S5976 laptop
AMD64
Linux Mint 14 Nadia with Cinnamon
Card: Realtek RTL8187se
Network Manager: WICD Network Manager, latest version. (Replaced original Network Manager)
Drivers: Windows XP 64-bit, downloaded from Realtek, operated via ndiswrapper 1.57; ndis originally proved faulty, attepted to follow repair instructions, all seems well (no errors on install of drivers/ compilation of ndis).
Code:
computer@computer ~ $ modprobe rtl8187se

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service networking restart
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop networking ; start networking. The restart(8) utility is also available.
