I am trying to get Gentoo running on an Acer Aspire 3935 and it is |
| 2 |
mostly working |
| 3 |
except for the wireless, which seems to have ... Centrino inside! :@ |
| 4 |
|
| 5 |
(Apologies for the long message, but I thought I'll post all I know in |
| 6 |
one go, so as to minimise a prolonged Q&A session) |
| 7 |
|
| 8 |
I have compiled on a 3.12.13-gentoo kernel: |
| 9 |
|
| 10 |
CONFIG_IWLWIFI=m |
| 11 |
CONFIG_IWLDVM=m |
| 12 |
CONFIG_IWLWIFI_OPMODE_MODULAR=y |
| 13 |
|
| 14 |
|
| 15 |
My /etc/conf.d/net section says: |
| 16 |
|
| 17 |
modules="wpa_supplicant" |
| 18 |
wpa_supplicant_wlp4s0="-Dwext" |
| 19 |
config_wlp4s0="dhcp" |
| 20 |
dhcpcd_wlp4s0="-t 45" |
| 21 |
metric_wlp4s0=20 |
| 22 |
|
| 23 |
|
| 24 |
My wpa_supplicant.conf has this section: |
| 25 |
|
| 26 |
network={ |
| 27 |
ssid="My_AP" |
| 28 |
bssid=00:A0:C8:1F:16:A2 |
| 29 |
proto=RSN |
| 30 |
key_mgmt=WPA-PSK |
| 31 |
pairwise=CCMP |
| 32 |
auth_alg=OPEN |
| 33 |
group=CCMP |
| 34 |
psk="secret_passphrase" |
| 35 |
priority=5 |
| 36 |
} |
| 37 |
|
| 38 |
Same configuration and AP works fine with other laptops, which do not |
| 39 |
have the same wireless chipset. |
| 40 |
|
| 41 |
|
| 42 |
With this laptop, running the netifrc script does not bring the card |
| 43 |
up. The firmware (in kernel) is loaded as dmesg shows: |

Another way I tried was without starting the netifrc scripts and |
| 144 |
instead using connman (supposedly a front end for wpa_supplicant). |
| 145 |
Surprisingly, now I get a connection, but alas, it won't last. Trying |
| 146 |
passing different parameters to the module I managed to get it to |
| 147 |
connect and spend around 7 minutes online at a time (after that time |
| 148 |
it will de/re-authenticate), if I modprobe it like this: |
| 149 |
|
| 150 |
# modprobe -v iwlwifi power_save=0 power_level=3 11n_disable=1 |
| 151 |
insmod /lib/modules/3.12.13-gentoo/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko |
| 152 |
power_save=0 power_level=3 11n_disable=1 |
| 153 |
|
| 154 |
Then it will de-authenticate with (Reason: 1) and re-authenticate |
| 155 |
straight after. This is an example from the logs: |

and so on. If I modprobe it with "11n_disable=1", it will |
| 247 |
de-authenticate but will not re-authenticate on its own. The connman |
| 248 |
status then shows "connman crashed". If leave power_level=3 to 1, |
| 249 |
which is the default, then it'll drop out sooner and not |
| 250 |
re-authenticate. |
| 251 |
|
| 252 |
Anyway I look at this it smells as a driver problem, but I do not |
| 253 |
understand why connman works albeit imperfectly, while the netifrc |
