無線寬頻常斷線

Usually the network connection is smooth only for a few minutes, then it slows down rapidly, and I can't load any pages at all. I was able to remain connected, but my 無線網路連線, always display "存取指標", instead of my wireless network name. Speed is also very unstable, sometimes it is 54 Mps, sometimes it is only 1.0 Mps.

I live in a studio, with my landlord providing a shared wireless network.

Is there anything that I can do to improve my connection?
