Yo Afripeeps - I tested this weekend again, if the wifey goes on FB I get massive ping spikes which didn't happen before. As stated before my ping goes from +-50 to 2500+ then back down again after a short while.
Difficult to isolate the issue. It's not when she loads any specific app or anything, it's quite random. Not really a huge issue, just super annoying. It seems like FB takes preference over any other traffic then takes all the bandwidth available for that specific call. Once it fetched the data then it returns to normal, but once another call is made then it spikes again. Not sure if you guys would be able to help with that?
I think we'd need to test with your username and see if we can recreate this. I can say I definitely haven't noticed this myself, but I'll try and test this scenario if I can.
