Wifi OK on USB, but not when installed
I'm loading Mint 13 on an Acer Aspire. Wifi works fine when booting from USB, but after installing the wifi does not work. I assume this means that I've got the correctd driver in the .ISO on the USB (Atheros), so what changes when it's installed on the hard drive?
Using the wifi power switch doesn't seem to have any effect.
Going back to boot Win XP, the wifi works fine there, too. The only difference between wifi under XP and under Linux is that the led is more visible (on more or on longer) under XP.
What have you tried? Are you just trying to use a browser and not connecting? Any error messages? Have you tried connecting to an ip with your browser from a terminal?
Try going to the site below and reviewing the commands to get more detailed information on your wireless hardware and post it here:
The link below gives you more options to get more detailed info:
No error messages, as the wifi appears to be powered off. I don't see any SSIDs. There is a hardware power switch on the Aspire, with click-on, click-off action, so I assume it's monitored by software, not an actual on-off switch. The associated LED emits to show activity, not power, so it's difficult to know what state the hardware is in if it's not transponding.
Hardware is the Atheros chipset. The following responses to the lspci command are identical for USB boot and hard drive boot.
01:00.0 Atheros AR242x/AR542X
Kernel Driver ATH5K
Kernel Module ATH5K
thanks for your help,
iwconfig wlan0 provides the following:
essid "lakehouse" (this was carried over from the USB install)
access point not associated
Retry long limit:7 RTS thr:off Fragment thr:off
no data on link quality, obviously, or rx/tx function
check out rfkill, it could be that the chip is soft blocked from making connections.
sudo rfkill unblock all
or something similar
also, to get more information, you can try restarting network-manager and monitoring the output of /var/log/syslog for network-manager messages relavant to the problems youre having.
I tried your sudo line, with no apparent effect. Then
and got the response, after about 2 minutes,
Failed to bring up wlan0
I am assuming that the Atheros chip is powered down, since there is that independent capability in the Acer.
