Wifi drops periodically on HP Pavilion laptop with Linux Mint 17.1
Hello all, I am new to Linux. I have a new HP laptop and installed Linux Mint. My wifi keeps randomly dropping. Sometimes it will reconnect on it's own, and sometimes I need to reboot in order to reconnect. When it has disconnected, I can't find any wireless networks and the button in network manger for wifi is "off" and can't be moved to "on." I've upgraded the kernel, and I've tried turning ivp6 off. Neither seemed to effect it. Those were ideas others had. My knowledge base is small and growing. Any ideas?

Pending resolution of this bug, one alternative is to to buy a cheap USB wifi adapter that is known to work in Linux.
Hi ServeChilled...
Welcome to the forum
Another good USB adapter that works "out of the box" is the the one here from ThinkPenguin.com. I personally own one of these adapters and have never had a problem with it.
Thank you both! I think I will get a USB wifi adapter.
Is it appropriate to call this thread solved, or should I leave it open for other ideas to come in, or in case the bug is addressed and then it can be noted here?

Hi...
You can go ahead mark it as "SOLVED," that way folks know that you've decided on a solution.
EDIT: On second thought, you might want to wait, there are some more ideas coming in...
Regards...

Reason: Added comment.
On some machines the wifi is 1 ,is turned using Fn+ 1 of F-keys that has a wireless sign on it. Are you sure that you haven't hit that combination by mistake?
I've decided to try a few more things. I followed the bug report beachboy2 mentioned above: https://bugzilla.redhat.com/show_bug.cgi?id=1108801
This is all quite above my head, but I tried the suggestion on comments 11 & 12. I've copied it below
"
The latest version of the Realtek driver is at http://github.com/lwfinger/rtlwifi_new.git. I will be merging that code into the kernel, but it may take a while. The code will build on any kernel version 3.0 or newer.
On any class of a modern PC, the fan should be running at least half the time. Not necessarily fast, but running. Having said that, my fan isn't running atm. But it does, I assure you.
To reiterate, I do have a wifi connection when I first boot up my computer. It usually continues working for awhile, up to a few hours. When it stops working, I cannot see any available networks in the network manager, and I cannot switch the wireless button to on "1" (I can move the button with my mouse, but as soon as I let go of the mouse button, the switch moves back to off "0"). When I reboot my computer I have wireless once again, for a time.
As you will see this is still all very new to me, but I am eager to learn. The commands did not seem to require sudo, but I ran them a second time with sudo and got basically the same responses.
So here is what I got:
iwconfig wlan0
wlan0 IEEE 802.11bgn ESSIDff/any
Mode:Managed Access Point: Not-Associated Tx-Power=off
Retry short limit:7 RTS thr=2347 B Fragment thrff
Power Managementff
iwlist wlan0 scan
wlan0 Failed to read scan data : Network is down
lsmod |rtl
No command 'rtl' found, did you mean:
Command 'rtd' from package 'skycat' (universe)
Command 'rt2' from package 'rttool' (universe)
Command 'rpl' from package 'rpl' (universe)
Command 'rl' from package 'randomize-lines' (universe)
Command 'rtc' from package 'nvram-wakeup' (universe)
Command 'rt' from package 'rt4-clients' (universe)
rtl: command not found
lsusb -v |grep Realtek |less
This gave me something about missing information but then the screen filled with ~'s, one per line, and finally "(END)" and then I didn't know how to do anything. The ~ $ prompt did not return. I had to close the window, "killing" a running process.
That looks for a module beginning 'rtl' to see what kernel modules you were loading. My bad. This one
Code:
lsusb -v |grep Realtek |less
lists the usb devices having the word 'Realtek' and sends it to less, a pager. Sorry about that. Space = next page; q = quit. I gather there was something there, because you got pages of output. If you are not getting sense out of that, try
I am so grateful for your efforts. As long as you want to keep trying to help, I'll keep trying your suggestions.
So here's what I got...while I had a wireless connection working.
iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:"SHAC Network"
Mode:Managed Frequency:2.437 GHz Access Point: 58:6D:8F:7A:4A:6D

lsusb -v |grep Realtek |less
Couldn't open device, some information will be missing

(END)
And finally, EDDY1's suggestion:
michael@C-3PO ~ $ ifup wlan0
ifup: failed to open lockfile /run/network/.ifstate.lock: Permission denied
michael@C-3PO ~ $ sudo ifup wlan0
[sudo] password for michael:
Ignoring unknown interface wlan0=wlan0.
