Intermittent initial connection
938982
Once the unit is connected properly it works at a range about 15 ft from the cell phone without break up, but initially connecting the headset can be frustrating. some times i have to turn the jawbone off and back on to reconnect to the phone when first using the headset. but over all, the head set works as advertised. i do find that the ability to physically turn the headset on and off to be a great improvement over the previous generation of headsets.

When it works it's fine, if not a little a too sensitive but it has dropped connection before to the point where I have had to delete from my PC and readd while also removing and reinserting battery to reconnect

Once installed it worked really well and i had a constant high speed connection.it just started doing this a week ago but  if the connection needs to be reset (as in the router/modem gets unplugged)the only way to re-connect is to restart my pc which is pretty annoying as you can imagine. As other customers have said, on the back the model number or some such code has been sharpied over so you cant read it.
all in all its a very nice little adapter but be prepared for an unstable network connection

I had no problem with it the first couple of weeks with this product but at times certain ports will just stop working...

Works great if you ensure it is connected.  Occasionally have to re-insert a few times to connect.

Out of the box, I have experienced the same problem as many others -- the connection to the PC repeatedly drops and then reconnects. I did not experience any loss of data. But my backup/copy process was interrupted each time the connection dropped. Having to sit there and constantly restart the process from the point of the latest interruption is a frustrating waste of time, at best. I'm sending it back for a refund.

It works fine most of the time.  There are some intermittent periods where I lose my connection but they normally last only for a minute or so.

It has serious issues on my windows 8.1 machine connecting to a 5Ghz Trendnet router. It resets connectivity 3-5 times continuously on system boot-up or switching from a 2.4Ghz to a 5Ghz connection. After resuming from system standby, it loses connectivity sometimes and have seen a couple of BSOD's. This really points to some very poor drivers. Hope they fix it soon.

Constantly drops from network. IF I get it reconnected (a big IF), it doesn't alarm when commanded.

Easy to set up, but works very intermittently. Typically I'll have to push the unlock/lock button 5-7 times before it sends the signal and unlocks the vehicle.

Worked perfectly the first first week.  Starting getting intermittent connection during the second week.  Died all of a sudden on the third week.

The wireless connection seems to be a bit sub-par, even with brand new batteries.  When the connection is running well, the mouse works well and is very convenient.  However, it's far to common to experience intermittent connection issues, making the pointer jump erratically.

Drops the connection every hour or so. Have no idea how to fix it, have tried different routers and different drivers but no use.

Less than a year of daily use before the connections became loose and intermittent.
