Hello, on my oneplus 9 device that I received today, as I mentioned in the title, I get max 1-2 mbit speed on wifi. There is no problem in mobile data. what do you think is the problem

hello, first check your modem settings.

If you are using 2.4Ghz WiFi this seems to be a router settings issue. Go to your router's admin page ( and change your bandwidth from 20/40 Hz or 40 Hz to 20 Hz. This solved my problem.
