Oh, in that case you're probably right that it's grub. Any idea how to tell if the udev is loaded yet?

I'm reading stuff like this:

https://www.gnu.org/software/grub/manua ... 02dinstall

Which is telling me about how grub can sometimes play badly w/ USB devices. But it's slow going over here.

And I still haven't gotten the driver working.

Guys, I've followed all steps in the forum (which are great btw). I was able to get my AM10 working on Ubuntu 10.04. However, it is extremely flaky. I have to use a VPN frequently. Connecting and disconnecting frequently as well as various other tasks usually result in my wireless connection dropping.

The interface disappears from iwconfig and the only way to get it back is to restart.

Also, my machine freezes quite frequently too. How can I get this more stable? This is still unusable since I can't really work with my machine constantly requiring reboots.

Thanks

What driver are you using? FYI this should now work out of box on 11.10. I'm using rt2800usb, without too many problems. I could try a little more on 11.04 as I have another box that uses it. But I'd prefer not to bother if I can help it.

PS I should mention that the grub issue is now fixed.
PPS I'm not sure if I mentioned on this forum that the AM10 now works out of box on 11.10. But that is cause for some SERIOUS celebration!

$ ndiswrapper -l

rt2870 : driver installed

Thus, I'm using the rt2870 driver. Does that look OK?

Here's the output from dmesg after my most recent loss of connection.

Also, it's unfortunate, but this is a work machine and I am unable to upgrade from 10.04.[/code]

[ohmysql]

I have no idea what's going on in your dmesg. But I would bet you're using the wrong driver. I've tried using rt2870 a lot and it never worked for me. rt2800usb worked right away - are you able to try it?

(http://www.ralinktech.com/en/04_support ... php?sn=501)

Either way, please do show me:

Code: Select all

lsmod | grep rt

And if you get rt2800usb

Code: Select all

modinfo rt2800usb | grep 0031

Oh and ndiswrapper never worked for me. I purged it from my system and blocked it in udev. I'm told that the rt2870 driver is already unstable on windows. Porting it to linux would therefore be even worse - disastrous, even. It constantly froze my computer.

OMS!

[duey]

hmm, so I can tell you that lsmod | grep rt didn't return anything. I see ndiswrapper in there, but nothing relating to the rt28** driver.

Also, I don't seem to see the rt2800usb driver on the link you provided. Am I missing something?

[ohmysql]

Yeah. I'm pretty sure you'll need to drop the ndiswrapper driver.

Sorry about not being clear about the link. On that page it's called rt28xx (then there's a few words then it says USB).

[duey]

OK, so I did the following:

sudo modprobe rt2800
lsmod | grep rt

Code: Select all

rt2800usb        33496   0
rt2x00usb        11260   1 rt2800usb
rt2x00lib           32165  2 rt2800usb,rt2x00usb
led_class          3764    1 rt2x00lib
mac80211       238896  2 rt2x00usb,rt2x00lib
cfg80211         148341  2 rt2x00lib,mac80211
crc_ccitt            1675     2 rt2800usb

modinfo rt2899usb | grep 0031 returns nothing

[duey]

I downloaded the zip that you recommended (i.e., 28xx .... followed by USB). I'm confused because when I look at the contents of the zip file I see rt2870.bin, which is the driver you told me not to use.

Can you give me steps, as if I was starting fresh, for what I need to do? I feel like I need to start from square one. I've tried so many things this week...

Also, thanks a lot for your prompt responses. I really appreciate it.

You're welcome.

I'm sorry to throw kind of giant threads at you. If you don't mind reading through them, you'll get a good sense of the necessary steps:

Especially that first link, #4 the guy shows more or less what you need to do.

I was a total n00b when I started doing this, now I can instruct people, which is pretty cool. I will be happy to walk you through it, but I have to run right now, and I was wondering if you'd be willing to review those threads. They give a lot of advice.

I'm going to post my personal notes on the steps - and I'll walk you through each one later if you're still having trouble:

Switching wireless drivers?

You'll want to black things out and set etc/modules

gksudo gedit /etc/modprobe.d/blacklist.conf
(to automate)
gksudo gedit /etc/modules
sudo rmmod [one]
sudo modprobe [the other]

How about them udev rules, eh?

gksudo gedit /etc/udev/rules.d/70-persistent-net.rules


ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="13b1", ATTR{idProduct}=="0031", RUN+="/sbin/modprobe -qba rt2800usb"


sudo service udev reload


How about that driver looking up my product and vendor ID?

/home/cool1/Desktop/Drivers/2011_0427_RT3572_Linux_STA_v2.5.0.0.DPO/common

rtusb_dev_id.c

Add under RT35xx

{USB_DEVICE(0x13B1,0x0031)}, /*Cisco Linksys AM10*/

common/cmm_wpa.c

Search for:

MIX_CIPHER_NOTUSE

Replace with:

WPA_TKIPAES_WPA2_TKIPAES

Used to be:

WPA_MIX_PAIR_CIPHER FlexibleCipher = MIX_CIPHER_NOTUSE;

In addition to changing:

HAS_WPA_SUPPLICANT=y
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

I just tried:

HAS_QOS_DLS_SUPPORT=y
HAS_DOT11N_DRAFT3_SUPPORT=y
HAS_DOT11_N_SUPPORT=y
HAS_STATS_COUNT=y



According to: http://ubuntuforums.org/showthread.php?t=1487397&page=4

sudo rmmod [olddriver] && sudo make uninstall && sudo make clean
sudo make && sudo make install

[ohmysql]

Question: when you open the zip file for the rt28xxUSB driver and look at common/cmm_wpa.c, does it say:

Code: Select all

HAS_WPA_SUPPLICANT=y
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

If not, you'll need to change those to y if you're plan to use network manager or wicd. Then you'll need to compile the driver. ("Compile the driver" sounds a lot scarier than it is. Believe me, if I can do it, you can).

Earlier in this thread, someone gives instructions on how to install driver compiling software. When that's installed, it just means you open terminal and do:

Code: Select all

make
sudo make install
sudo modprobe [driver name]

The first sets up the driver code from the config files, some of which you can set manually. The second and third install the driver on your computer.


OMS!

[duey]

well, some progress, but still no dice.

I followed all of the steps you laid out in your notes. When I run iwconfig I now see a ra0 interface. That wasn't there before. Also, the network manager seems to indicate that I have a wireless connection, but I'm still not able to actually connect. I can't even connect to the router. Not sure what else to say. This has been a ridiculously frustrating process.

Let me know if you need me to post any output so we can work through this.

Thanks,

[ohmysql]

Yeah...

It took me 3-4 months, of many, many steps to get this working. I have a feeling we'll get you going in at most a few weeks with the work I and many others have done. But suffice it to say, I know frustration.

You didn't answer a few of my questions, which is going to slow things down - did you read the threads I sent you? Especially the first one?

And also, please see my question about "common/cmm_wpa.c." It's very important. If either of those say "=n" we're going to need to recompile the driver from scratch.

Anyway, please post:

Code: Select all

modinfo rt2800usb | grep 0031
lsusb
cat /etc/udev/rules.d/70-persistent-net.rules
cat /etc/modules
cat /etc/modprobe.d/blacklist.conf
sudo iwlist scan
iwconfig

Also, please look in your additional drivers settings. On mine, I had an rt2870 driver that appeared one day.

Probably what you're going to end up doing is removing the current rt2800usb driver and replacing it with one we're going to slightly alter ourselves. All the instructions are in those threads or you can wait for me to walk you through it.

What happens in network manager? Do you see the wireless network you're trying to connect to? What kind of encryption do you use?

You may end up needing to use wicd instead.

I know it's a lot of questions, but trust me, they're all essential.

Also, I did make the necessary modifications to the driver, both source code and config.mk file by switching a couple flags from n to y. I then uninstalled, compiled and reinstalled the driver.

As for network manager. It does not display any of the available wireless networks. Again, I have to run, but hopefully this output is enough to diagnose this thing.

On another note. Is there a better piece of hardware I could purchase that might be easier to install than this? That is another option I am willing to entertain. The issue here is that this is a work machine and I need internet ASAP. So basically, if I can't get this worked out by the end of the weekend I have to find a piece of hardware that works straight out of the box. Do you have any recommendations on such a device?

Thanks again.
