Please help...can't access wifi on Gateway NV77H20u

Postby justiceanthony on Sat Feb 02, 2013 3:42 am

Hello everyone, Im very new to linux. I installed it on my Gateway NV77H20u laptop as the sole operating system (fully migrating from windows). My laptop is a core i5 4gig ram laptop and i installed the 64bit version of linux mint 14. It's quite smooth and I'm really enjoying it. My only problem, however, is the fact that i can't connect my wifi or any wireless network unless through a cable. I've tried reading some threads on the linux forum...but i'm always lost because I don't understand anything (about terminals and so on...lol)...I'm really new to linux and I really need help. Pls help me as to what to do. I want to make linux mint my permanent OS.

this is the result after running this comand: sudo /usr/lib/linuxmint/mintWifi/mintWifi.py

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload

Since the script you are attempting to invoke has been converted to an

First of all welcome to the forum.
Second of all, you must know a little about terminals etc because you managed to run the command mintwifi, which is just the right thing to do.
Thirdly, I am not a wifi expert by any stretch of the imagination, but when I look at the output of mintwifi I can see that you have no wireless connection.

Let's start with the simple stuff (the simple stuff is all I know with regard to wifi :? ).

In your panel you will have an icon for the network manager. Left click this. Is wireless enabled?

Does this laptop have a wireless hotkey (most do, mine is Fn+F5 for example). Press whatever key combination yours is and wait for a few seconds - if it works you should get a pop up saying your connection is established.

If that doesn't work at all (ie no pop up notification) has this machine ever run windows in the past? If so was wireless switched off when windows was installed. There have been occasions in the past when this has prevented Linux from reversing the setting. A difficult question to answer because you probably don't remember - neither would I. So in this case we have to have a look in the terminal again, so open it and type:

Code: Select all
rfkill list


After pressing enter what you would hope to see is something like this:

Code: Select all
phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: no

If it is soft blocked try the following command:
Code: Select all
sudo rfkill unblock phy0


NB the type - phy0 - is read from the output of the first command - yours may be different so check and amend that if necessary before using the command.

Hard blocks are caused by hardware switches (ie the key combinations we tried earlier) and cannot be undone by this command.

My last shot is for you to have a look at the connection itself (they should happen automatically but maybe yours hasn't). So left click on the network manager again and click Network Settings. In the settings dialog highlight 'wireless' then click on 'options'. In there you need the ssid of your wireless network and the mode (infrastructure if you have a router) on the wireless tab, and on the wireless security tab you need the security set to the correct type (usually wpa2 personal) and your correct network password entered. I also suggest ticking the 'available to all users' box as well. If you happen to know the mac address of your wireless card you can enter it in the 'device mac address' on the first tab but this is not usually necessary.

That is about all I know on the subject, hope it helps.
