| Post subject: | Rosewill RNX-G1 802.11b/g USB 2.0 Wireless Adapter: RTL8187L |
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. |

| Post subject: | Configuring from MythTV Menu: WPA2 vs WPA |
I have attempted to configure WLAN0 from the MythTV Menu:
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:
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

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. |

| Post subject: | Working! |
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...) http://www.dlink.com/products/?pid=333 |

| Post subject: | Streaming Results |
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. |
