[How-To] Alternatives of Samsung WiFi Link Stick

Post by erdem_ua » Sun Oct 04, 2009 12:37 pm

Related WiKi page for newcomers:

While I inspecting firmware, I saw some kernel modules on '/lib/modules' directory related with WiFi dongles.

I think compatible WiFi dongles uses Ralink RT2870 or RT73 modules.
Than I gues the compatible WiFi dongle modules are uses this chips:
RT73: RT2571W, RT2573, RT2671
RT2870: RT2770 and RT2870

Potentially working on RT73 kernel modules are:
Asus WL-167g
Sitecom WL113 v1-002
GW-US54HP
D-Link DWL-G122 (new rev)
Digitus DN-7003GR (VPR 1.0)
Belkin F5D7050 Ver 3
Edimax EW-7318USg
Hawking HWUG1
Linksys WUSB54GR

I couldn't find dongle names with compatible with RT2870 libraries. But if you use such dongle in linux, please try it on TV and tell me if its working or not :!:

I found samsung device ID on the web and I think this is WiFi Link Stick ID because I don't know if samsung produces another WiFi dongle....

Code: Select all

{ USB_DEVICE(0x04E8, 0x2018) }, /* samsung */
I don't know if Samsung put a filter for dongle detection code (probably they put it). But this modules could be run on your TV with a little work (or without work)
I couldn't test it because my USB dongle uses rndis_wlan driver. If you donate me a usb dongle that uses rt73 or rt2870 library, I will work on it. :D

1. Samsung use cutdown drivers
2. ralink original driver may don't support the samsung dongle out of the box. (too lazy to compare the list :cry: )

I think we could use hex edit for alternate device ID strings too.
Since chip is same, it will work with original driver :)
But needs testing with those dongles...

erdem,

The wlan usb stick that you quote IS the Samsung WIS09, compatible with our TVs. I happen to have one and it works fine. I also happen to have a D-Link DWL-G122, HW rev. C1. On a normal linux box it uses the ralink RT73 driver. I plugged it into my TV (UE40B7020, fw 2008) and it isn't even recognized, let alone that it works. So, unless I missed something, I guess that the RT73 driver in the samsung firmware needs some attention before it will work.

I searched 32B650.zip for rt73's and rt2870's driver file. I found directories under "/linux/linux-r011/drivers/" but there is no file. They removed codes. I think this breaks GPL rules.

Is it too early to fill report at
http://gpl-violations.org/ :?:

I don't know if debian compiled kernel modules work on TV (probably will work) but I tried to compile Kernel and modules from source with cross-arm tools and I failed. I will try again with native cross arm linux (thanks qemu).

You don't needed to paste all string to here. It's enough that being use of rt73 or rt2870sta driver.

Road seperate 2 ways from here. One of them jump in that kernel modules with IDA an change required strings, that enables rt73 and rt2870sta devices in that approach.
But other way is far better, compiling our kernel modules, which enables any WiFi dongle on you samsung TV.

I tried once but I failed. It's better to open topic for compiling Samsung Kernel.

Hello!
I am posting a short report from testing Edimax EW-7318USg USB WiFi b/g dongle with LExxB650.
As you may know, it doesn't work natively with B65x, but here are some useful facts:

part of /proc/bus/usb/devices:

Code: Select all

T:  Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  2 Spd=480 MxCh= 0
D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=148f ProdID=2573 Rev= 0.01
S:  Manufacturer=Ralink
S:  Product=802.11 bg WLAN
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=300mA
I:  If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
E:  Ad=81(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E:  Ad=01(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
when the WiFi stick is put into USB2 port - it generates /proc/kmsg messages:

Code: Select all

<6>usb 2-1: new high speed USB device using ehci-s5h2x and address 2
<6>usb 2-1: configuration #1 chosen from 1 choice
and when is released:

Code: Select all

<6>usb 2-1: USB disconnect, address 2
LED on the dongle is not blinking at all. Nothing.

Similar WiFi driver with source code can be found on the author's website:

George.

EDIT: A few minutes ago I hex-edited VIDs in rt73.ko file, then executed commands:

Code: Select all

rmmod rt73
cd /dtv/usb/sda1
insmod ./rt73.ko
and... it seems to work now! Great!
I've modified only 4 bytes of rt73.ko:

Code: Select all

Comparing files rt73.ko and RT73_ORIG.KO
00049C9A: 8F E8
00049C9B: 14 04
00049C9C: 73 08
00049C9D: 25 20
Now I have to check if it can be seen in the TV's menu.
(I am using simple serial cable without patched firmware, so I don't know how to exit telnet after executing it on the console).
