Here's what I've found. I have a strange situation where I get very strong non-Wifi interference one channel 6 of the 2.4Ghz Wifi spectrum. Unfortunately I don't have a spectrum analyzer so I cannot pinpoint the source. When AP's (Apple, Netgear, etc.) are set to channel 6, even if I place my device (Laptop, Tablet, iPhone, etc.) physically next to the AP, I have trouble authenticating and passing data. So, as a result, my home WiFi AP's are set to channels 1 & 11 (although I primarily use 5.8Ghz these days)
Because I cannot set the Wifi channel on this hotspot, when I turn it on, it automatically selects the channel which appears "free" -- aka channel 6 since there are no other Wifi devices on this channel.
But, I found that if I turn the hotspot off, take it outside far away from my house, and then turn it on it will select a different channel (channel 1 or 11). I can then carry the device back into my house and it will STAY on the previously selected channel as long as I do not power cycle the unit. On channels 1 & 11, despite the overlap with my home AP's the hotspot works great.
I've been using it to and from work all this week in my car (I bought it so my kids could watch Netflix & YouTube in the car) and it has been working great!
Overall, I am very happy with the product. The price, and data costs are by far the best value when compared to other carriers.
But, I would still make the following comments observations:
1) The firmware really needs to be updated to enable setting the Wifi channels manually
2) The lack of at least some rudimentary firewall support needs to be investigated
3) I'm amazed in this day and age that 5.8Ghz support was not included
4) I'm disappointed that this Hotspot does not support ANY international bands. I was going to return it and get one that did, but NONE of the hotspots on your website support international bands.
I had hoped to be able to use it in Europe this Summer.
