Hello,
Hope I'm posting this in the correct forum. Thought about posting under RedHat, but I'm guessing this is more of a general Linux question. Searched but didn't see any posts which matched my crtieria.
QUESTION:
Whenever I leave my netbook alone for a while and it goes to sleep, when I bring it back up my wifi is no longer connected. And no matter what I've tried, I cannot get re-connected unless I reboot. Then it connects fine again.
Hardware:
Asus 1005HAB eeePC purchased from BestBuy. Came w/ Win7. I installed CentOS 5.5 using free space. Working great so far after 2 months.
Notes:
I was able to get this laptop (netbook) to connect to my wifi router at home. Whenever I boot into X-Windows, I get a prompt to enter my gnome keyring password, then it automatically connects to my wifi router.
After I wake it from sleeping, it shows the network connection has been lost. I can see my network name from the list of wireless networks in Gnome. If I try clicking it, it tries for like 30 seconds then fails.
My wifi router is setup using wpa2. I'm using the NetworkManager service to manage things. wpa_supplicant service is disabled.
I did however, input all my details in my wpa_supplicant.conf file (even though I saw this posted somewhere: "Network Manager ignores any wpa_supplicant.conf settings you use, and use the wpa_cli program to configure wpa_supplicant "on the fly" when it starts")
lspci shows:
02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
iwconfig shows:
wlan0 IEEE 802.11bgn ESSID
