Ping spikes on wifi

[Keronero]

So i've been living with these constant ping spikes that occur every minute and last about 5-10 seconds for 2 years. Since the beginning of this week i've been trying to solve them trying numerous solutions and none of them seem to work. Probably the reason of these spikes are because i live in an apartment and there are lots of other routers than can interrupt my connection.
I've also realized that if i connect my laptop to my router these spikes never happen but since the router is on the ceiling and about 8 meters away from my bedroom i can't use wired connection. Any help would be much appreciated.

Unfortunately, that's one of the biggest drawbacks with Wifi.

If you have the option to use the less conjested 5GHz signal, that may help...
You could also monitor the channels available, and select one manually (opposed to the usually defaulted "auto" setting), allowing you to pick a channel with less traffic.

Beyond that, wired is the only way to improve what you're dealing with and, considering you're in an apartment building, even the "best" fixes you can do to your wifi is still going to be somewhat limited.

You could consider a powerline adapter (which will use your electrical wiring to provide ethernet). Your router, although on the ceiling should have a power outlet that it's connected to? and you could likely have your laptop near another power outlet? That could help things.

I've considered buying a powerline adapter but there's no power outlet near our router so it's not possible and i've tried changing channels but the ping just worsens every time.

How is your router powered if there is no outlet near it?

Even if it has a long power cord and runs the length of your ceiling down to an outlet....... running an ethernet cable alongside it, down to the same outlet...... isn't likely to be any more intrusive/ugly?

It has a cable behind it that leads to the power outlet in a little room we use as the basement through inside of the ceiling and the wall and the power outlet is behind the freezer and there's no way to plug a powerline there and even if we can we can't find an ethernet cable long enough to go there.
