Connected to Wifi Network but Internet not working

[ataberkbunyat]

Hey guys total Linux newbie here. Decided to try out Linux after my hate of Windows 8/8.1 on my Acer Aspire M5-M83P.
I tried to download 12.04 but my wireless card was not even recognized with it when I installed it
over Windows 8.1. So in desperation I downloaded a 32 bit version of 13.10 and everything was
working fine during installation but now I cant even access the internet. Thank you in advance.

Hi,

please open a terminal with CTRL+ALT+T and show the outputs of these commands:

lspci -nnk | grep -iA2 net
lsusb
lsmod
iwconfig
rfkill list

Does LAN work?

[ataberkbunyat]

Here you go.
I cannot test LAN or just a direct plug due to my house not letting me. Only LAN worked in 12.04 when I tried to at a friends house.

Deactivate the N-mode of the driver (bug) and the power management:

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo iwconfig wlan0 power off

Reboot and check

dmesg | grep iwl

[ataberkbunyat]

Here is the code that it spurted out. Also update. Wifi works but not optimally when I turn networking on and off. Its a tad and slow and it took a while fo the first page to actually load but it seems ok ish now.

Does the "Power Management" stay off? Keep an eye on the output of -

iwconfig

If it seems to be fluctuating (on and off at different times), try creating a blank file in /etc/pm/power.d directory to disable the default wireless power management script -

sudo touch /etc/pm/power.d/wireless

You may have to log off/log on (or reboot) for the change to take effect.

I think we would also like to see your current driver parameter that are in effect. Please post the output of -

grep -R [[:alnum:]] /sys/module/iwlwifi/parameters

Here it is. I am posting this from the laptop it worked fine when I turned it on with no problems. Going to reboot now due to the other line of code.

/sys/module/iwlwifi/parameters/11n_disable:0

Clearly, the code (echo "options iwlwifi....") proposed by praseodym is not in effect. Did you run them correctly?
If yes, there might have been a typo. Please show us the output of -

cat /etc/modprobe.d/iwlwifi.conf

And the blank file to disable the default power management was a trick that should be ONLY used if the normal method (the one praseodym suggested) fails to keep it off.

So.. was the Power Management fluctuating between on/off by itself? Or turning On again by itself? If not, that "blank file" trick was unnecessary and may even worsen the performance in some cases.

[ataberkbunyat]

Pretty sure the blank file screwed up everything. The echo options iwlwifi was typed correctly as well. How can I delete the blank file? Thanks in advance.
