Q4: Data throughput is low
If you have successfully set up the 4G router but the data throughput is low,
for example, when testing with speedtest.net, here is what you can try to
dragonize the problem.
Please note: generally the 4G router cannot beat your smartphone in speed
test. This is because the modern smartphone uses a different design which is
equipped with much higher grade of modems. For example, Samsung S10 has
a Cat 20 modem and iPhone 11 has a Cat 19 modem. They are 6 times faster
in specs than a Cat 6 Quectel EP06 modem.
1. Try to use QMI or QCM protocol instead of using ttyUSB mode.
2. Ask your carrier to make sure the APNSettings are correct. Some
carriers use different APNs which may yield different speed.
