Are you guys using TMHI or other T-Mobile service?
FYI: The window killed my signal, even with the antenna… have you tested it outside?
Low-E glass will kill radio waves so keep that in mind when receiving/sending cellular signals through glass.
don't forget to change your MTU settings on the modem; try 1430, or 1420. Cheers
Interesting to know how this will affect the WiFi signal since you blocked it with the foil!
I don't use the Wifi on the X3000, but use a separate Wifi router (in AP mode) connected to X3000.
