The 2Wire HomePortal 1000SW is 802.11b AFAICT. Thus, even if you can get this to work, streaming anything above standard quality will not produce satisfactory results. That said, if you just want the RTV to be able to net connect, you might be able to make it work by putting the WRT54G into "client mode" using the Sveasoft firmware. In my experience, this doesn't work very well and has a lot of caveats (including only supporting one wired device at a time behind the client mode WRT54G). You can try though.
