Wifi very slow with home network and fast with hotspot from mobile phone

Yesterday I installed fresh instance of Manjaro and wifi connection was working correctly. Today it’s working very slow and simple webpage is loading few seconds and sometimes I need to refresh. When I changing wifi network to network from my mobile phone hotspot then everything works correctly.

I have windows 10 too and both networks are working correctly there. I compare wifi settings on Manjaro and windows but I didn’t find any differences (automatic DHCP with static IP addresses, secure with WPA2-Personal, the same DNS for IPv4 and IPv6).

Before Manjaro I had Fedora and there was the same issue but I didn’t try to analyse that. Sometimes internet was working correctly and sometimes not.
