Now that my ADSL line is up again I’m not sure if I should switch back from LTE to ADSL. Every time they repair the phone line, don’t they add extra attenuation to the line?

I’ve attached the external antenna to the Huawei B593 but haven’t experienced any perceived increase in signal quality. I suppose I should mount it to the outside of the wall. At least I can now move the modem to a more convenient spot and put the antenna in an optimal spot.
