WLAN on the phone very slow?

I have some problem undzwar I have a 100,000 line at home for a while and have a new phone (huawei mate 20). My Internet on the phone is very slow yt and Instagram load for a long time but s.PC (LAN cable) loads everything very quickly.

Where is the router in your apartment / house?

He is one floor below me but on my old mobile (s6 edge) the loading times were shorter

Basically check your speed with the smartphone.

Once directly on the router and once a floor above.

If it is slower through the concrete surface, it is due to the nature of the ceiling.

You can change it by testing with another WLAN standard.

At 2.4 GHz with the n-standard

At 5 GHz with the ac standard

In order to distinguish it, it can name so differently in the dual-band WLAN routers (different SSID's adjust, configuration side of the Routers, in the extended view…) and then times to test which standard is better.

PS:

Also, a more suitable site and installation location (tilt devices vertical / horizontal) for the router, can help. Hall? Staircase? Where the ceiling is thinner or does not exist… Do not put the router in a corner… Better in the middle of the room, raise elevated.
