Hi all, and sorry for my poor english.

I have a belkin usb wireless receiver,

Code:

Bus 001 Device 004: ID 050d:7050 Belkin Components F5D7050 ver 1000 WiFi

working fine with rt2500usb (except the led that doesn't work), until i suspend my pc. At the resume, wifi is disconnected, and the power signal of my receiver seems to be mooooooooore lower then before. 95% of iwlist scan doesn't recognize any network, the remaining 5 recognize my net, but not the others two that it found before suspending. Connect tries fail (probably due to the poor power signal)

Code:

[javier@archbox ~]$ ifconfig

(Why it sets crda for US if I'm from Italy???)
Before I blacklisted 'em, the system loaded the modules rt73usb and p54usb (nothing's changed)

Sorry for the length of the post :roll:

Which kernel are you using?

Because you didn't specify anywhere that you are in Italy.

You need to configure the correct country code yourself, although according to the Ralink specs the device does hold some information about the region it was distributed the specs indicate that information should not be used. So setting the correct country region completely relies on userspace configuration for the information.

Thanks for the reply, in the near future i will take a look to crda.

I looked over your initial post a couple of times and completely overlooked that line with the kernel version. :oops:

Could you use the register dump script: http://kernel.org/pub/linux/kernel/peop ... regdump.sh
and create a dump before and after the suspend & resume cycle?

Note that you need to enable CONFIG_DEBUGFS, CONFIG_MAC80211_DEBUGFS and CONFIG_RT2X00_LIB_DEBUGFS
and mount debugfs.

ehmmmmmmmm, are you talking about kernel compiling flags? I never compiled the kernel, is it really necessary?

Try mounting debugfs, perhaps (very likely) your distribution has enabled it by default.

sorry, I'm a dumb...
Have I to mount debugfs on my /?
How can I do it? :oops:

Edit
I mounted debugfs in this way

Code:

mount -t debugfs none /sys/kernel/debug

but when I run the script, this is what I get:

Code:

ls: impossibile accedere a /sys/kernel/debug/ieee80211/phy*/rt[0-9]*/: No such file or directory

Where I'm doing wrong?

The directory ieee80211 contains phy0, but phy0 is empty :?:

Not sure about this, but is your wireless interface active when you checkec the contents of that folder?

Yes, I'm connected by that.
I didn't do anything about this, CONFIG_MAC80211_DEBUGFS and CONFIG_RT2X00_LIB_DEBUGFS
Is there something I have to do?

Since you have the /sys/kernel/debug/ieee80211/phy* folder you have at least CONFIG_MAC80211_DEBUGFS enabled.
But I don't understand why the folder is empty, there should be multiple files/folders in that directory.

Please use this command:

Code:

cat /proc/config.gz | gunzip | grep DEBUGFS

this will display if all required config options have been enabled.

Weird that the directory is created even when mac80211 doesn't support it, on the other hand... that means that CONFIG_RT2X00_LIB_DEBUGFS doesn't need to depend on it..

Anyway, I'm afraid that you still have to recompile your kernel with the previous mentioned options enabled.

Thanks, I'll look into it.

I edited your post because adding things like this inline is making the entire thread unreadable, and offcourse we have a very cool attachment feature on this forum.

Sorry admin, when I posted I thought that the text in code tag would have been shown in a scrollable frame. :mrgreen:
