    We would like to announce that the compatible adapters page at www.tivo.com/adapters/ has been updated to include two 802.11g wireless network adapters. Support for these adapters is included in the 7.1x software release. If your Series2 box has not received software version 7.1 yet, you can request the download at www.tivo.com/priority/. Requests are normally processed within 3 business days (often sooner).

    If you do not already have a wireless adapter, the two 802.11g adapters that we are recommending are:

    - D-Link DWL-G120 version B2
    - Netgear WG111

    These adapters can be purchased at many local or online retailers. The DWL-G120 is also available at the TiVo Store.

    Important Notes

    - These new adapters work only with newer Series2 boxes that TiVo service numbers that start with 230, 240, 264, 540, 590.

    - The speed of these adapters is comparable with the 802.11b adapters on our list, so we do not recommend changing from an 802.11b adapter to an 802.11g adapter at this time. We added support for these 802.11g adapters because they are more widely available that then 802.11b adapters on our list. Also, the 7.1 software will recognize additional 802.11g adapters not listed above, but we do not recommend using those adapters at this time since they have not been tested and may not perform as well as the ones that we recommend in daily connections and/or network transfers.

    - 802.11g adapters should be used only if you have a home network with a router. They will not work for a "Peer to Peer" connection between two TiVo boxes or a TiVo box and a PC. You will have to stick with 802.11b adapters if you want to do that.

    So does this mean that USB 2.0 has not been enabled? Why is it that a Linksys USB200M will perform so well on USB 1.1, but a G adapter won't speed things up just enough to allow near-realtime transfers? All I'm looking for is the speed I used to get when I was able to have a wired network. My new setup requires 1 Tivo to be wireless. I know I could do the wireless bridge thing but that is kinda pricey.

    USB 2.0 is enabled in 7.1 for the platforms that support it (all Series2 boxes except for the ones that have service numbers starting with "1"). There are other hardware issues on the box that limit transfer speeds over a wireless connection, so we do not expect the 802.11g adapters to be considerably faster than the 802.11b ones at this time. Many customers have reported much faster speeds using USB 2.0 wired adapters however or wired-to-wireless bridges as you mentioned.

    Maybe I'll just take the D-Link I'm getting from Tivo rewards to best buy and try to return it towards a G bridge. I miss my fast transfers!

    Thanks Bill - I was just looking at some of the deals on "g" wireless. Good timing of the announcement.

    Keep up the good work guys.

    Yeah thanks Bill for the announcement. Not quite the "Get a G adapter and get blazing 54 Mbps tranfers" announcement I was dreaming of, but thanks nonetheless.

    Does support extend to WPA encryption?

    No changes have been made to the wireless networking screens in 7.1. WEP encryption is still the only supported encryption method at this time.

    So, are 802.11g adapters not enabled on 140xxxxxx boxes (i.e. they won't work) or are they just not officially supported (i.e. TiVo will tell you "too bad" if one doesn't work)?

    And yes, it's true that even a 802.11b at theoretical max can outrun USB1.1, I (like many) don't get near theoretical max due to signal strength, encryption, etc. So while 802.11g won't be massively faster, it'll still be faster.

    Plus, it would be nice to have my whole WLAN be "pure"-g.

    Right. It takes about 3 days now because the glut of the list has been already taken care of.

    When everyone was complaining about the list, it was said many times that during a roll out, the exponentially increase the speed of the rollout and the number of people who get it.

    Anyone looking to buy the D-Link adpaters I found them at Fry's yesterday for $49.99 and on top of that there is a $20 rebate.

    Any chance the LinkSys WUSB11 v 4.0 will ever be supported? I bought it without understanding that TiVo was telling me to use a non-current version of the adapter. I was able to find a v. 2.8 on eBay, and I'm wondering if I should just sell the 4.0 or hang onto it until TiVo supports it?

    This sounds about as fully baked as the TiVoToGo rollout.

    Any idea when (or if) WPA will be supported?

    I thought that USB1.1 was 12Mbs (and this rate was achieved in practice), and 802.11b was 11Mbs (but the effective rate was more like 5-6Mbs), so 11g would effectively double the throughput to 12Mbs. I got the D-link adapter, and it seems to be somewhat faster than the WUSB11 (MRV slightly faster than real time at HIGH quality), but not the doubling that people who use the bridge technique get. It was kind of disconcerting when plugging in the D-Link and the TiVo spontaneously reboots! Or when it went from "Almost there" back to the initial boot screen once. The D-link driver seems to do evil things to the Linux system when installing itself. And yes, TiVoBill warned us that the 11g adapters would not do as well as the bridge technique. The 11g drivers they are using must be REAL dogs compared to the drivers for the wired adapters.

    My understanding is that the Linksys WUSB11 4.0 uses a chipset that we do not have support for (there are likely no Linux drivers for it). We do have releases a few times a year to support additional adapters, but it is unlikely that we will be adding support for that particular adapter.

    I am not aware of any plans to add support for WPA encryption at this time.

    Your performance may vary, but our tests did not find significant difference in the transfer speeds achieved with 802.11b and 802.11g adapters in the current software release. Some customers have reported slightly increased Multi-Room Viewing transfer performance. The reboot is actually a known issue. It happens if you remove an adapter and plug a new one in too quickly. We suggest waiting 30 seconds after unplugging an adapter before plugging in the new one.

    Just wondering if this lack of speed increase is considered a "bug" which is being worked on for a future update, or is the 11g support solely to address the decreasing availability of the "old" 11b adapters. Unlike the Tivo2Go transfer rate problem, the MRV wired vs. wireless transfer rate issue seems to be in the network code somewhere (drivers and such).

    We are exploring ways of improving 802.11g transfer performance in the future.
