How much internet speed in Wi-Fi should I typically get on my smartphone?

I have a Samsung Galaxy Note 10 Lite, which according to the internet should be able to support speeds up to 1.2Ghz. I have a contract in which my provider should give me access to 500mbs on wi-fi but this is the most I ever got with my phone, I normally get 280mbs or lower. Is this considered normal, despite being a wireless...
