My Wilson Sleek makes data download speed WORSE

I agree it may be dropping from 4g to 3g or even 2g Check the indicators on the phone or.... If it is an Android.. Download the app"Network Signal Info" this is free and it will tell you the type of connection when you go to the Mobile Tab.. NOTE. if you are connected by Wi-Fi as I am now the info there is.. Defective.
(But the info on the Wi-Fi page is good)

The front end of the receiver is getting overloaded and creating electrical noise. Or, the thing has become self quieting due to the location of the external antenna on the Sleek. That is, much like a howling PA system when the mic gets too close to a speaker. Can't hear the person at the mic when this happens.

I am trying to not be too technical here. I'm a telecommunications person with 40 yrs in the field.

Those signal levels are enormous in the RF world. You system will work with 1/3 of those.

Using my Moto X Pure as a hotspot or a Ellipsis Jetpack, my 4G Sleek also slows downloads (Verizon version). I ONLY use it when I'm in a fringe area and the device cannot achieve a stable 4G connection on its own. Even 1 bar of signal is enough to work fine by itself. I have not experienced the level of slowdown you're seeing, but...

-61 is a lot of signal for LTE, why are you using the booster? Typically my device is fine by itself down to -95 or so.

Mr Wizard: I show -44db signal with Sleek on, -61db with it off so Sleek is clearly amplifying. One other weird fact: I can get .53 Mbps download and 13mps upload with Sleek engaged,but normal download vs upload differences with Sleek off.

MiFi set for lte

But what version sleek ?

Does the sleek cover the same bands that the MiFi uses for lte
Or is the MiFi switching to 3g or 1x, became that is the strong band coming from the sleek

Mifi is set for LTE only. Sleek is the 4g version

Sleek is an old product, perhaps not suited for today's technology. Get a WeBoost.

I've experienced the exact same thing on AT&T. Only correlation I have is proximity to a military base. No answer from at&t or willson or weboost or whoever they are now.

That's happened to me before. Weird.
