Hi i'm new here, just applied unifi VIP5 (forget the name, cheapest package one anyway )not even one month.
my modem, router, phone,IPTV all put in living room while my PC is in my room, in between need go through like 2-3 walls...
and then recently i just bought the repeater because i notice (and some feedback from ohter people) that wifi signal of the default router is ultra sucks.

so when i play dota2 right, i choose SEA server which have lowest ping...
default streamyx 1mbps i can get 80-110 ms , but unifi can get around 20-80ms which is good but recently i getting lag spikes and warning disconnect from server few times for this few days...

My IPTV is okay , smooth no problem...
so i wonder is router or modem problems? if need get a new one, how much need to budget?
i'm not on 24/7 for router and modem, most of the time on overnight till before i go work, and maybe on for weekend start from friday night till monday morning.
thanks in advance for help.
