 Posted: Tue Apr 05, 2011 4:05 am Post subject: [Solved] D-Link DWA-131/RTL8192SU Driver Problems |
 |
|
Hello,
I have been using Gentoo for a while now and I have been getting network by bridging my MacBook's wifi through ethernet but I want the PC to become independent of the Mac, so I am going to try to use a D-Link usb wifi adapter. The model is dwa-131 and it is a rtl8192su chip. I am having lots of trouble getting this little device to work with Gentoo. It works flawlessly with Windows. I actually remember getting it to work with Ubuntu once but I can't get it working with Gentoo. I have downloaded the rtl8192su driver source code from realtek's website and compiled it. I have it showing up in iwconfig. Here is the output:
| Code: | iwconfig wlan0
wlan0 unassociated Nickname:"rtl_wifi"
Mode:Auto Access Point: Not-Associated Sensitivity:0/0
Retry:off RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0 |
Are there problems with the output above?
Here is the output of lsmod:

When running 'ifconfig wlan0 up', the entire computer freezes and requires a reset to resume functionality. Can anyone help me solve this?
Thanks,
Joey

I think I grabbed the one from portage but I'll try this one.

ill be damned. i didnt even realize we had it in portage

I still haven't tried it but this really sucks. I don't really want to switch distro's because I love Gentoo and this is the only problem I haven't been able to fix on my own. Is there anything else I can do? The main reason I want to do this because my router isn't letting me host a minecraft server when my PC is connected through a bridged network on my MacBook. I figured the easiest way around it would be to get a direct connection to the router from a USB wifi device. I would plug the ethernet into my router but its all the way downstairs so that isn't an option. Could it be my kernel? I am running the stable x86_64 from portage, 2.6.36-gentoo-r8.

kernel is kernel is kernel, regardless of distro, exception being any distro-specific patches (or external patchsets you may use)
just had a thought; the core of this seems to be that, although there is an 8192SU driver in the kernel's staging section, your specific model 8192 isn't included
| Code: |
Symbol: RTL8192SU [=n]
│ Type : tristate
│ Prompt: RealTek RTL8192SU Wireless LAN NIC driver
│ Defined at drivers/staging/rtl8192su/Kconfig:1
│ Depends on: STAGING [=n] && !STAGING_EXCLUDE_BUILD [=n] && PCI [=y] && WLAN [=n] && USB [=y]
│ Location:
│ -> Device Drivers
│ -> Staging drivers (STAGING [=n])
│ -> Exclude Staging drivers from being built (STAGING_EXCLUDE_BUILD [=n])
│ Selects: WIRELESS_EXT [=n] && WEXT_PRIV [=n] && EEPROM_93CX6 [=n] && CRYPTO [=y]
|
And from digging through the source, it *does* look to support your model
| Code: |
ricker rtl8192su # pwd
/usr/src/linux/drivers/staging/rtl8192su
ricker rtl8192su # grep -r 0x3303 *
r8192U_core.c: {USB_DEVICE(0x07d1, 0x3303)},
|
This is true as of the kernel version I'm checking, 2.6.36-zen1 (zen-sources shouldn't have any staging drivers the regular sources don't)
Reports on the Ubuntu forums are that the staging driver actually works quite well - http://ubuntuforums.org/showthread.php?t=1522815
SO...what i would do:
-remove the driver from the realtek site completely. I do not know the correct procedure from this, but the Makefile seems to hint you can simply do "make uninstall"
-go back, reconfigure your kernel, build the rtl8192su staging driver; again, if you get stuck here, give a shout, should be able to help
-you will still need the firmware blob, so if you've done any messing with that, just re-merge that package
-at this point you should be able to modprobe rtl8192su, wlan0 should show up, see if you can do ifconfig wlan0 up without a freeze; if so, I'd imagine wpa_supplicant and the other usual tools should work fine

Thanks for your support man. I really appreciate it. I was about to drive myself insane. I am going to try this and post back if it works. Your research leads me to believe that it will.

Thank you so much man it worked perfect. All I had to do was remove all the other drivers I installed and configure the kernel to enable staging drivers and the RTL8192SU driver and it worked perfect. You also need the firmware. Problem solved.
