Because I like to stream movies through my (wired) home network from the mythbox, I don't really have a need or desire for a wireless adapter, the exception to this would be when I packup the mythbox and bring it to another family member's home. Wireless then becomes a very desirable capability. That being said, I would like an inexpensive and easy to install wireless device.

I just ordered this item shipped from for $10. Techbargains has a code for a Newegg discount and free shipping: Code: EMCKHJJ52 (Exp 2/17). Newegg reviews indicated that this item is linux friendly, so I Googled ArchLinux RTL8187L.

As for the installation: A Google search yielded: https://wiki.archlinux.org/index.php/Rtl8187_wireless

I imagine there may be others in the community contemplating wireless as well so I though this might interest them. After I receive \ install the adapter I will post my results.

Until then, I would be interested if others have had any success \ lessons learned that would be helpful when I install the adapter.

Bonus points if you can explain the IE lines and the hex strings.

In the near future, I will try to register this with my wireless router and post the results.

I have attempted to configure WLAN0 from the MythTV Menu:

    Service Menu -> LinHES Configuration -> Network Settings

My wireless router is setup to use WPA2 Personal AES encryption. WLAN0 was configured through the menu as WPA and active. The menu's encryption options are:
    1) none
    2) WPA
    3) WEP

Has anyone been able to configure their wireless card through the MythTV Network Adapater menus with a WPA2-AES router?

I tried using the following commands to setup a wireless adapter:

Code:
[root@mythtv etc]# ifconfig wlan0 up
[root@mythtv etc]# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 00:1A:EF:17:E4:4E
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

[root@mythtv etc]# ifconfig wlan0 down
[root@mythtv etc]# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 00:1A:EF:17:E4:4E
          BROADCAST MULTICAST  MTU:1500  Metric:1

[root@mythtv etc]# ls -l wpa_supplicant.conf
-rw-r--r-- 1 root root 32656 2009-06-12 14:00 wpa_supplicant.conf


A check of /etc/wpa_supplicant.conf shows that it was untouched by the mythTV menus described above. Should this file be modified or should an attemp to troubleshoot be performed first?

I am not sure what the troubleshooting procedure should be: any troubleshooting suggestions are appreciated.

Apparently there are numerous tools like NetCfg. I am not sure if this will only complicate things or help solve the problem. I hope someone with experience can offer guidance to get over the learning curve. Thanks.

The procedure that needs to be followed is here.

First generate the configuration items:

Code:
wpa_passphrase [ssid] "passphrase"


copy the results to /etc/wpa_supplicant.conf

I removed the examples from /etc/wpa_supplicant.conf and the procedure says to add this to the top of the configuration file:

Code:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel


Start the process:
Code:
# wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf

Maybe the line above should be put in rc.conf?
Code:
# pgrep wpa


Bounce the NIC:
Code:
# dhcpcd wlan0


Check the NIC for an ip address:
Code:
# ifconfig wlan0


Should the wpa_supplicant command be put in the rc.conf file so that it is executed at bootup?

I can't speak to getting a wireless adapter working, 'cuz I've never done it.

The time I did set up a wireless Mythbox, I used a D-Link G-820 adaptor with good results... (On SD, not sure wireless G will handle HD streaming...)

I tested a wireless G system to stream from my mythbox to a laptop. Both using wireless. The system was able stream a 720p movie with no problems and plenty of leftover bandwidth. Wired is preferred, however, it sure is nice to have a wireless option.
