The Unite Explore by itself has a built-in antenna, so to get the best performance from it, it needs to be placed where the signal is the strongest. Note you can also add an external antenna to it if your reception needs improving.
I'd suggest trying to move it around your home while watching the detailed signal strength information. The Received Signal Strength (RSRP) and the Signal Quality (RSRQ) are two indicators of the quality of the connection to the tower. Good signal strength is typically better than -100, e.g. -90 or -95. Good signal quality is a more positive number, like +5 or 0 and indicates the amount of distortion or noise in the received signal. If you have a poor signal strength (like -104 or -110), you typically have worse transmission speeds. But you can have good signal strength (like -90) and poor signal quality (like -14) and you still have poor speeds because the received signal, although strong, is noisy. So it is harder for the hotspot to pull the data signal out of the received signal.
Please do the following:
Using your smartphone's browser, bring up the Unite Explore's signal strength information. To do that:
Browse to http://attwifimanager. Enter the password: attadmin
Click on Settings, then About
In general, you want the RSRP and RSRQ (found near the top of the right hand column) to be as positive as possible (e.g. -90 is better than -120.
While watching the RSRP and RSRQ numbers and carrying the hotspot, slowly walk completely around the inside of your home (1st and 2nd floor if you have one), keeping the hotspot near the exterior walls. You may need to refresh your browser to see the numbers change. Note the signal strength as you do so.
Find where the RSRP and RSRQ are as positive as possible.
Place the hotspot nearest the location where you found that strongest signal.
