Internet speed in a hidden wifi is good in speedtest but too slow in everything else

Hello
today i have change my Wifi to a hidden ssid but the internet speed is too slow ,it’s good in the speedtest :
Ping = 28 ms
Download = 10.56 mbps
upload = 1 mbps
so i want to know if it is the config when i add it problem or what .

Just checking:

  • do you confirm you get similar speedtest results when your Wifi is not hidden?
  • do you confirm you do not have that issue when your Wifi is not hidden?

No i don’t have it when it’s hidden ,in my phone connection is too good

So when i use the vpn every thing is good now !!!
