Deteriorating connection 9.2.5

So, after installing 9.2.5 ive noticed that my latency starts consistently, rapidly climbing after about an hour of time in-game.

This affects both “home” and “world” latencies, and once they go over about 80ms ping, it becomes unsalvageable.

Some of the things I’ve checked / helpful(?) notes:

  • this is a wow-only issue, and only started after 9.2.5
  • restarting fixes it, but only if i wait about a minute.
  • disabling other network usage does delay the problem, but does not prevent it.
  • I’ve verified files through battle.net
  • I have addons, but disabling them is not an option for a fix.
    – these are:
    Details (dps meter only)
    All The Things
    My Roleplay
    TomTom waypoints

Ideas for what could be the cause /what i should try /others with the same issue?
