Hi everyone,
As far as I know, there is a wifi extender and the access point. The wifi extender is using wifi from router to the extender, then wifi from extender to devices such as computer, laptop, smart phone, TV, etc. Access point is wire from router to the access point, then wifi from access point to devices. Now, what is wireless access point? Isn't it another name for the wifi extender?
Can someone with the knowledge/experience explain this?
Thanks in advance.
