It's not too often that I am given the opportunity to make a product announcement, but this was just too good to pass up! Many of you have heard rumor of a TiVo-branded wireless 802.11g adapter (TiVoPony showed it back in the summer) and it has now come to fruition. :up: And I don't feel like I'm biased when I say that this is one good-looking adapter! http://www.tivo.com/2.7.1.asp

And this is the first 802.11g adapter that is compatible with ALL TiVo Series2 standalone platforms (even the first generation models with the 110, 130, and 140 TSN prefixes)!! It has a full MAC chipset to optimize performance with a TiVo DVR (cannot be used on a PC or Macintosh).

For those of you who were following this thread, you may have noticed that one was visible on my desk. ;)

It does indeed look really nice!

It has a full MAC chipset to optimize performance with a TiVo DVR (cannot be used on a PC or Macintosh).
What does this mean in terms of real transfer speed numbers? Will the seemingly unbreakable barrier around 600kB/s using wifi USB adapters finally go away, giving it full 802.11g capacity?

That does indeed seem to be the chip used in this device.

The on-chip processor and memory are capable of running all wireless functions on-chip, allowing embedded system designers to add wireless LAN technology to a variety of platforms without burdoning the host processor.
So this should increase the transfer speed, since the TiVo will not have to do the WiFi-related processing, just like using a USB-ethernet adapter increases the speed, correct?

DCIFRTHS,
you can go the bridge route, then you can get a wireless tivo with WPA.
I bought a refurbished WPA-enabled 802.11g bridge and a used USB-ethernet adapter for about what this new TiVo adapter costs.

FYI the adapter doesn't plug directly into the back of the TiVo... you'll need to use the USB extension cable which isn't visible in the TiVo store photos. My current adapter works reasonably well and I prefer less cable clutter, but I do have a new adapter on order for the sake of testing. When I'm done, I'll raffle it off. :) (Unless the speeds are blazingly fast, then it's all mine.)

This may take the burden of WiFi off of the processor, but I wouldn't expect a huge difference in TTG transfers since the main factor causing slowness there is processing power required to mux the streams into a single file. Although it could have a significant impact on MRV transfers since they don't require the muxing process.

I'd actually be interested in seeing a comparison when someone gets one.

The full MAC architecture of the TiVo Wireless G adapter does indeed offload work from the CPU of your TiVo box, which in theory can result in an increase in networking throughput. In real-world use, wireless throughput depends on your network environment, what other processes are running on your TiVo box, and a host of other factors. Some users will see a noticeable improvement in wireless throughput for the TiVo adapter compared to other wireless adapters, and others will not.

With regard to WPA, at this time the TiVo Wireless G adapter does not support WPA, and supports WEP only. We are aware of our customers’ desire for WPA, and are investigating WPA implementation for a future software release.

oooo, it's pretty.

one question, though, before i buy it, i have the d-link adapter on my tivo, can i still use that one on my computer, or is it gone?
