You've got to be kidding - Logitech expects folks to gimp their home network security in order to make their product work - this is getting better and better.

Thanks for the suggestion, I tried that durring my 12 hours of troubleshooting, but it still couldn't connect to the network. None of my other devices have issues with my network's settings, so I'm not going to waste any more time trying to get this thing to work. I put it back in the box and am going to return it once I get the receipt (Christmas gift).

I bought a new LG plasma, went to update my settings on my 670 and software wont reconized remote. Thinking it was the remote being a few years old and broke. I went shopping online for a new model at Tiger Direct. After finding out that i'm not the only one having problems I called back and canceled shipment!

Logitech really needs to update their software!

In order for the Harmony Link to find the WIFI signals, I found they need to be on the same subnet as the PC it’s connected to.

In my situation, the Harmony Link worked fine for a couple weeks.  In fact, it worked so well, I purchased a second unit.  Because of their limitations (one unit per email account – bad idea Logitech), I wanted to adopt an actual naming convention and not just use my email address.  Following the instructions, I pressed the red button on the bottom of the unit and as expected, the red LED started flashing.  When the LED is flashing red, I’ve found it forces a firmware update.  I have no idea what firmware is running because Logitech doesn’t show that information during the upgrade or anywhere on the product page.  Ever since the firmware upgrade, the unit hasn’t been able to find any WIFI (802.11) signal.

As I explained to the less-than-impressive service agents, there is plenty of 802.11 signal in my area.  My iPad can easily see my SSID’s, my neighbor’s and the “hot-spot” 802.11 signal from my iPhone when it’s on.  There is no reason whatsoever the Harmony Link shouldn’t be able to find a handful of these signals.  After discussing the problem with customer service, they told me I needed to speak with tier-2 engineers.  After waiting for 5 business days, I decided to take another crack at the problem myself.  It’s probably worth mentioning Logitech’s customer service has nothing to do with actual customer service.

Although I can appreciate Logitech’s desire to simplify the instructions as much as possible, the manual is totally inadequate.  There are plenty of customers out there who understand the technology and would benefit from more detail.  Showing such limited information makes it difficult, if not impossible for users to fix their own problems.

Finally, out of desperation, I connected a new router/access point into my cable modem.  I connected my laptop to the new WIFI signal, went through the process again and to my surprise, it worked!  Based on this success, I can only assume that the PC software is doing some kind of a connectivity test to the Harmony Link as part of the process when is searches for WIFI signals.  With my network, I’m routing between network devices and I believe that caused the connectivity test to fail.  To me, is makes no sense at all for Logitech to be testing the connection.  The manual says it’s simply looking for 802.11 signals and based on my experience this is not the case.  Shame on you Logitech for not disclosing that information.  If you would have, I would not have wasted 5+ hours of my life diagnosing this stupid problem!!!

On other post it says some routers only use 802.11n or just one frequency like 5 ghz instead of the 2.5 ghz used by the link. On other posts it says the harmony link only uses 802.11g. Don't know if this is true. Just what ive read. Look on you web page login on your router and check these options and see if dual freq. broadcast is enabled. Just look at your setting for router.
