bug report: pldt fibr cutting out every peak hour sa makati cbd, don’t be noob and just reboot.
symptoms: 200mbps plan pero drops to 2mbps after 6pm, ping jumps 50ms->800ms lalo na sa discord calls or valorant queue. light sa modem blinks green pero actual throughput garbage-iperf3 server test shows 90% packet loss downstream.
tried lahat ng common advice: pinsan ko sabi “i-reset modem sa likod, three mins unplug.” ginawa, 30mins ok then same shit. tita group chat: “bili ka ng tp-link extender.” nagbayad 1.5k sa shopee, worse pa, added 20ms latency. pldt fb community: “call 171, mag-demand ng tech visit.” queued 45mins, tech came after 3 days, “sir ok naman” after speedtest.net (which is peak hour blind lol).
finally solved: suspicious ng splitter ko-yung cheap plastic one from install 2yrs ago, GPON standard pero underrated for 1gbe. binili new nf-sli from pldt teleshop makati (P450 cash), direct splice sa ont port 1, bypass old splitter. boom, sustained 185/175mbps sa iperf3 even 8pm, loss <1%. simple fix pero pldt techs rarely check it.
tip sa mga kabayan: benchmark properly with iperf3/udp not speedtest, check pon loss budget (aim <28db or you’re screwed per itu-t g.984). scaling laws dictate splitter grade matters more than raw plan-yung mga “mabilis ba wifi ko?” peeps skip the science, end up rage-posting. test your chain now before ulap summer hits.
