I bought the TiVo AG0100 Wireless G USB Network Adapter for use with my old Series 2 Tivo. This was great when at home and connected to my own network. Once I moved away to college, with a heavily protected network, this adapter was harder to use. As far as connectivity, the TiVo AG0100 Wireless G USB Network Adapter worked well and always connected to my home network for purposes of updating the guide and account information. For $35, this device was well worth the benefits of not running phone cords to the Tivos throughout the house. I definitely recommend this device for older series Tivos.

My opinion is 100% my own - good or bad. I hope you found this review helpful. If so, I'd appreciate you clicking the "helpful" button!

The "G" adaptor works just fine!!! No delays with online streaming or transfers. Only one wire to the tivo's usb port. Where the "N" requires a maze of wires for powering the N, then another wire to the NETWORK port of the tivo. So many messy wires, and no real benefit gain in function over the G adaptor. And the G costs half the price as the N. If you need a tivo wireless adaptor, stick with the G. I stream online and transfer HD video between my 2 premiere tivos. The G adaptor transfers fast and I can start watching an on-goining transfer right away. So just stick with the G adaptor and save money and the wire maze mess you have with the N adaptor. I got a second G adaptor for my second tivo premiere, and now use my N adaptor only on my LG HDTV. The N adaptor is basically a wireless supply device. I suppose you can use the N adaptor to connect any networked device that is not wireless on its own, but has a network port plug. The tivo N adaptor can access your N wireless network in the home, and the network N cord can be plugged into any device with a network port, making that device wireless. So I now use my tivo N adaptor only on my LG HDTV, not wireless on its own. I use the "G" adaptor(s) on my 2 tivo premiere units. Everything works perfect! The G adaptor.. 1 usb wire, great function. Tivo menu setup on the G adaptor. The N adaptor needs to be connected FIRST to a PC (or mac) computer network port in order to set the wifi security access codes. The G adaptor is so much more reasonable and user friendly. No PC needed setting up the G adaptor. Done all though the tivo adaptor menu.

The one thing I dont understand is why Tivo still will not have a wifi receiver pre-installed when you buy it. Since they don't though, this accessory is perfect.

I own three Tivos and have one of these for each, there really is no alternative to it.

At my vacation house, the phone wiring will not work with dial up for Tivo for some reason. However using this I connect no problem. Additionally at my primary residence I have one on both Tivos which has a couple of great features.

1 - If you have two Tivos, each with one of these attached, you can transfer recordings between the units, which is really nice.

2 - Through Tivos mobile website you can program recordings from anywhere.

3 - You can cancel your home telephone!

These little units are really great, Tivo just needs to learn to have them come pre-installed with the units!

I have 2 Tivo's at home and a Mac running Tivo to Go software and I am constantly moving shows back and fourth between tivos and the computer. I once had this adapter on both TiVo boxes and the transfer rate was decent. I could start a transfer and within a minute start to watch the show being transferred without having any "pauses".

What I didn't like about this was the design. The foldup antenna piece I think should be more solid or "lock" in the up position. I positioned this behind my TV and if a cable hit it, etc the antenna piece woudl fall down and the transfer rate woudl slow considerably.

As for installing it, couldn't be easier. Plug it into the tivo, go to your network settings and enter your network information. I had it up and running in less then 5 minutes per tivo and have been running the adapters since 2/2009 so it's been about a year and a half with no issues.

I would recommend this.

Worked perfectly right out of the box in my Tivo Series 3 XL HD. By work I mean the TiVo AG0100 Wireless G USB Network Adapter for TiVo Series 2 and Series 3 DVRs completed initial calls, updated the TIVO software AND worked great under WPA encryption. So, I didn't have to use WEP on the network! I have not tried any downloads or video on demand yet. I found out that signal strength worked better at higher elevations in the room. So, I set the wireless adapter up with an 8 foot USB extender cable reach to the top of the TV Cabinet. I also fooled around with the flip up antenna angle until I maxed out at 49% signal strength (as reported by TIVO). This unit does the job but my Dell laptop thinks the signal is better than that. Maybe the Dell Laptop has a better antenna or perhaps better amplifiers?

Update September 2010 ... this device still works great after many months. I found out that if you own 2 TIVOs and both have their own AGO100 Adapter --- you can (if not DRM limited by the broadcasters) share recordings between the two machines. In other words, programs I recorded in the living room were able to be imported onto the TIVO in the bedroom right through the wireless device. Great feature!
