Followup on the Belkin F5D8053 and Ubuntu

13 Replies

Seems my previous blog post about the Belkin is found quite often when people search for how to get it to work on Ubuntu in general, also with ndiswrapper. Please note, my post is not about getting it to work with ndiswrapper (that worked fine in my case, but I’m on 32-bit Ubuntu, and didn’t try it on 64-bit). There are quite some posts about getting it to work with ndiswrapper (also posts about it not working, will drop him a comment). This one also explains how to unpack the windows driver if you don’t have a windows installation.

Anyway, so far about using ndiswrapper. Recently ralink released a new version of it’s native linux driver, 1.3.1.0 which can be found on their linux support page, and with this one I got the Belkin F5D8053 working. It doesn’t see the 5Ghz network I’ve over here, but well I don’t want to do normal Wireless over that network anyways, since that will decrease the speed of the Wireless to Wireless bridge I setup. I’m still blaming incompatibility between the Belkin USB stick and the Apple Airport routers for the Belkin not being able to find the 5Ghz network.

What I had to do to get it working.

1. make sure you can build kernel modules: sudo apt-get install build-essential linux-headers-generic
2. check if your Belkin USB id is listed in the driver: lsusb | grep Belkin | awk '{print $6}';, which returns 050d:815c in my case. Then use the id found in grep -i '0x050d,0x815c' include/rt2870.h if that returns a result, then skip step 3 since your device is already supported by the driver (please note the '0x' added before the 2 parts and the ',' in stead of the ':').
3. If it’s not there add it: edit include/rt2870.h Search for Belkin; Copy/Paste that line and change the usb id of your device to that you found in step 2.
4. Edit os/linux/config.mk and change the HAS_WPA_SUPPLICANT=n HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n to =y.
5. Edit Makefile and remove any line containing /tftpboot (still don’t know why they are in there, and running make as normal user fails if they are in there)
6. make && sudo make install
7. Edit (as root) /etc/modules and add rt2870sta to it (remove ndiswrapper if you used that before to get it working).
8. Either reboot or do modprobe rt2870sta to get it working (if you used ndiswrapper before you first need to run modprobe -r ndiswrapper). You will also need a /etc/init.d/networking restart if you won’t reboot.

That was all I needed to do.

Trying to get the Belkin F5D8053 v3 to work on Ubuntu Hardy without ndiswrapper

Update: I got it working now, see my new post about it.

If I look at the Windows driver for my new Belkin F5D8053 it is based on the RT2870 chipset. There is a native driver available for this chipset. Unfortunately so far I’m not able to get it to work. This version is already linux 2.6.24 ready so I don’t need to apply these patches. But even though I’m able to compile it, I’m not able to use it, yet. Side note: the warning in the Ubuntu forums about backing up any existing configurations in /etc/Wireless/RT2870STA is useful, since you need to put your configuration in there and it’s removed by the make install.

One strange thing in the make process is that it wants to copy the result to /tftpboot. I’m not sure why it wants to do that, and I’m almost certain it shouldn’t be a part of the make process…

The first problem I ran into was the fact that the USB Device id for my Belkin, 050D:815C, is missing in the driver (that could be a big hint about it not being able to work for it …) so I added that to the include/rt2870.h (I copied the line for the other Belkin device and changed the device id into mine).

With that added, my Belkin is detected by the driver as ra0. But even when I compile it with:

HAS_WPA_SUPPLICANT=y
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

I’m not getting my device visible in the gnome network manager, so I tried the command line configuration options.

First I tried only configuring the /etc/Wireless/RT2870STA/RT2870STA.dat. But if I had only that file configured, the activity light was turned off on an ifup ra0. So I guess that’s not right.

Then I tried to configure it in the /etc/network/interfaces as described on the Ubuntu forums. The light staid on when I did ifup ra0 but no DHCP lease. So finally I tried the “iwpriv” way described here. But still no DHCP lease.

So I guess I’ll have to contact ralink, to see if they are able to help me out here.
