Hello, I am testing Internet from T-mobile with a Huawei B525 router for about 2 weeks, I have an option up to 20 Mb / sio as much as I actually download, so ping from 17 to 23 is tragic, usually above 100, while at night it is ok and is then about 35-70. I use it in Kielce. I was thinking about mounting some TP-Link antennas TL-ANT2408CL, but will it help stabilize the ping?
