@JimT1000 : I solved this problem by getting new wifi rounter which produced more strength and stable wifi signal. I Got wifi 6 Deco rounter and it is on use for morecthan one year. No more problem!

@David_Hoang_560 Hello everyone, my issue has been solved as i upgraded my router. My wifi signal is stronger than before and the HS200 connects and works well already for few months since changing...

@JimT1000 I got the same problems and removed, installed it many times, but it does not help. Anyone other suggestions? Thank you very much!
