Using RT3070 WiFi dongles with Samsung TV
Posted: Sun Mar 03, 2013 1:05 am
Hi guys, I am trying to make a Linksys WUSB100 v2 (RT3070) compatible with my Samsung TV (UE32C6700). I was able to patch the EEPROM values according to the information I found on this topic: viewtopic.php?f=3&t=14
Now, the dongle is recognized by the TV, and the LED has a normal behaviour (it blinks fast when scanning, otherwise it lights intermittently), but does not find any APs. If I force my computer not to use (rmmod) the rt2870sta, rt2800usb, rt2x00usb, rt2800lib, rt2x00lib modules and I insmod my modified rt2870sta driver the same behavior occurs. I have played with the source code of iwlist and I found that ioctl(skfd, req, pwrq) with the requests SIOCGIWSCAN / SIOCSIWSCAN is not doing its job. I cannot find the implementation of that function; the only information I got was its declaration in ioctl.h:
Does anyone know where it is implemented? (I hope to find the cause of the issue by tracing the functions involved in the scan)
Returning to the main problem: Would it be possible to fix this issue by changing some values in the EEPROM? (In other words, is this idea stupid?).
Since I don't want to change the firmware of my TV, I guess that is the only solution. If that's right, could anyone send me an EEPROM dump of a RT2870 dongle? That can be easily done with: iwpriv ra0 e2p. Of course, feel free to hide the MAC address. Thank you very much!
PS: Yes, I really have searched on this forum and Google before asking. However, all the posts about ioctl or rt3070 were not useful to me.
