How to delete saved wifi hotspots on iphone ios 8?

Question

iPhone

The problem is the following wifi point at work is simply called "WIFIololo".
At home, I have exactly the same network name WIFIololo, but different passwords and, accordingly, the iPhone cannot connect to the network, although it sees it.
Question - how to delete saved points?
What I wrote above is to understand what the point is, the problem is completely different, so do not suggest putting the same password on two dots or changing the name!

Answer 1

Settings - wifi - select a grid - "forget network" / "renew lease"
Or reset network settings.

Answer 2

The most trivial option is to delete it in the accessibility zone of the connected grid in the usual way in the settings.
The option "if there is a Mac" is to remove it from the settings from the computer (then it should disappear from the iPhone when synchronizing).
If nothing helps, you can try (did not try):

Settings > General > Reset network settings
