I had an issue as well, and there are two things I did that made it work fine (although I haven't used my laptop a whole lot lately for mythtv): First, put your router in G-only mode, if possible. This increases the throughput by a considerable amount (for me, mixed mode gave me around 1 meg/sec transfers, while G-only mode gave me around 2 megs/sec). For the ipw2200, I noticed that when trying to stream mythtv stuff, I get a lot of errors in dmesg regarding the firmware messing up or something. I think this is due to hardware encryption. If you use WEP on your network, then add the module parameter hwcypto=0. This eliminated that issue for me. These two things made everything stream just fine for me even at pretty high bitrates. I did LiveTV before and it worked ok. ~Lou
