Did you make sure that the router on your TiVO can use WEP encryption? I know the Linksys router I tried wanted a specific type of encryption (I can't remember if it is WEP or WPA).

What wireless protocols are the various devices running? It's possible that the new Mac is running a faster protocol (either g or n) and the router is detecting that and switching to the higher speed mode, leaving it incommunicado as far as the slower devices are concerned. Go into your router and make sure it's set to compatibility mode (something like "b AND g" or "b, g, AND n").

I purchased the Linksys because (amongst other reasons)m Tivo (at the time), only had one wireless access point on it's recommended list (and that is the one I purchased).

It is set to all modes. FWIW, the router is a G, the Wireless cards in the old Mac and in Susan's PC (which I haven't checked yet) are all G. The new Mac is N. If I recall correctly, the WAP hooked up to the Tivo is B.

So far, everything is working okay since I did the earlier off then on of the New Mac's Airpoort card.

As much as I like this wireless keyboard, I really miss having the 10-key, Page Up and Page Down, Home and End keys.

I did to, but it didn't like my encryption - which I just checked and is WPA. WEP is the less secure of the two, but is what the TiVO will take from the Linksys card I have.

I'm researching if the TIVO branded card has the same restrictions.

Good to hear!

If I remember correctly, TiVo started supporting WPA about a year ago.

Then my TIVO sucks, or I need a different router (I'll go with the second). I had such a hard time finding the specific version that I'll go with the TiVO branded router when I buy a next one.

Well, I set up my network with WEP and the Tivo sees it just fine (event tested it for this post).
