[ath9k-devel] N not in use.

[Dmitri Seletski]

Hello.

I have noticed several things about driver(apart from failures)

1) If i force N- it doesnt connect at all, it can "see" my wireless when

its in pure N mode.

2) I have noticed, every time i restart my pc, i can connect to wifi.(at

the moment it's in b, g, n mode)

3) with earlier version of drivers, machine used to hang a lot, with no

way for me to determine(X was on)

4) previous versions were not giving that much of error messages in

dmesg, however, once network disconnected (and if computer didn't hang)

i had very small chance to connect

5) I have noticed i get generally problems with computer. But it could

be due corrupted c-lib(because of quite some "hot" reboots)

Driver i used for those attachments - is todays driver, so everything is
fresh.

What can i do to improve anything? i am not programmer... :(
But i'll try to test.

Thanks

Dmitri

What do you mean by forcing to N- mode ?

This is a bit weird, can you give us some more details ?
Configuration of the AP, connection type ( encrypted/open ) etc.
Also, please enable CONFIG_ATH9K_DEBUG in config.mk of compat-wireless,
and load the driver with the modparam debug=0x2000 and post the kernel log here.

I don't think this should affect ath9k, but still, please remove the binary
kernel module 'nvidia' when you are reporting kernel issues.
