karta wifi gubi zasięg

[gosu]

mam problem z kartą wifi - czasami na laptopie jest internet a czasami znika tak jak by karta sieciowa gubiła zasięg jest to dosyć irytujące bo nie można nic spokojnie zrobić w internecie bo co chwile gubi zasięg.

Czy ma ktoś pomysł jak to naprawić ?

________________________________

W między czasie czytałem trochę na innych forach i wykonałem następujące czynności:

1 zmiana:

Pobrałem: https://www.kernel.org/pub/linux/kernel ... 3-1.tar.gz

Kod: Zaznacz cały

make defconfig-iwlwifi
make
sudo make install

Następnie pobrałem nowe sterowniki: https://git.kernel.org/cgit/linux/kerne ... 60-9.ucode

Kod: Zaznacz cały

sudo cp ~/Desktop/iwlwifi-7260-7.ucode /lib/firmware/  
sudo modprobe -r iwldvm  
sudo modprobe -r iwlwifi 
sudo modprobe iwlwifi

rebot - testowanie - niestety nie pomogło ;/

informacje na ten temat znalazłem tutaj: http://askubuntu.com/questions/331667/n ... version-63

2 zmiana:

Znalazłem informacje na temat powersave: https://bugs.launchpad.net/ubuntu/+sour ... ug/1354975

zastosowałem się do porady jaką tam znalazłem:

1. In the /usr/lib/pm-utils/power.d directory in the file wireless I changed in the end of the file with two off so that there is no wireless powersave:
case $1 in
true) wireless_powersave off ;;
false) wireless_powersave off ;;
*) exit $NA ;;
esac

na chwile obecną testuje od 30 min i działa zobaczymy jak długo mam nadzieje że znalazłem przyczynę problemu będę to jeszcze monitorował
