Everything was running since very recently.
I usually have a constant ping around 50 to 60 ms towards NA-EAST servers (i live on a french Island / Guadeloupe), but since 3-4 days i have a constant high ping going up to 150 ms.
I tried a lot of things, the problem came by it self as i really didn't change anything to the network.
So i will explain down there how is my system set.
My fiber router (//400 m/bits.s) is link to a other wifi extender a TL E115, and my repeater (TLWa855re) is linked to this router. At last my computer is connected to the repeater with a eternet cable.
So as i said i didnt change anything in the past days on my internet config, so i dont really understant why did this happened.
I upgraded every link of the system and nothing changed.
Do you guys have an idea?
