is there a client side solution to 90k stuff?

like opening a port or something?

i keep getting the symptoms of it with enemies disappearing while allies stay moving then it recovers after a couple seconds and sometimes the full on 90k followed by unable to load characters and having to reboot client

and it is seriously making anything past garuda HM just impossible to even try

90k is just a disconnect. It can be caused by anything, ISP dying, Router Dying, Modem Dying, someone on your network choking the bandwidth, could be a bad route, could be on SE's end, though you'd see alot more people if that happened.
