I just purchased a WMCE54AG media extender on ebay and successfully connected it to my Windows XP Media Center PC. It seems to be working fine except I can not access Online Spotlight. I get a dialog box saying "Site Not Designed for Media Center" and asks me to View Later / View Now / Cancel. I select to view now and get the Online Spotlight menu options, but can not do anything with it. This functionality works fine on my PC. Is there some setup that I missed on the extender? I tried to upgrade the firmware, but when I intalled, it said I have a newer version so I canceled it out. Any help would be greatly appreciated.
Well, after extensive trial and error, I finally figured out what the problem was. The Linksys extender is not compatible with IE7. After rolling back to IE6, I was able to see Online Spotlight in the media extender. As a note of caution, I had upgraded to IE8 beta 2 and Online Spotlight stopped working on my media center PC as well. I got the same error I did on my extender. This ultimately was how I realized the problem was with the IE version.
