<br><br>First, put your router in G-only mode, if possible. This increases the<br>throughput by a considerable amount (for me, mixed mode gave me around 1<br>meg/sec transfers, while G-only mode gave me around 2 megs/sec).
<br><br>For the ipw2200, I noticed that when trying to stream mythtv stuff, I get a<br>lot of errors in dmesg regarding the firmware messing up or something. I<br>think this is due to hardware encryption. If you use WEP on your network,
<br>then add the module parameter hwcypto=0. This eliminated that issue for me.<br><br>These two things made everything stream just fine for me even at pretty high<br>bitrates. I did LiveTV before and it worked ok.<br><br>

As it happens I'm using the ipw2200 driver - I built the latest version on sourceforge and use the newest firmware. Oddly enough wpa_supplicant is able to authenticate with the router, but for the most part ipw2200 is unable obtain an IP. I'll keep tinkering... If I can't get wpa to work consistently soon I'll try dropping back to WEP protection since that seems to have better in-driver support. I read in the driver docs that WPA is enabled in the newest version of the driver, but I have no idea how to utilize it :-|
<br><br>Oh well.. Enough rambling from me. Thanks! Anybody else who feels they have something to add here, I'd still gladly hear from you :-)<br><br>/drdaz<br>
