Gaming Lag Three Walls From the Router in a Kingsford Share House: a Repeater + LAN Got LOL Ping Under 20 ms (HFC 105M)

Student · KingsfordHFC 105MShare house · HouseGaming lag / high pingRepeater + LANLOL ping under 20 ms

In a four-person share house in Kingsford on an HFC 105M plan (Netcomm router), one student’s room sat three walls away from the main router, and games like League of Legends and Steam titles were unplayable at night — high ping, packet loss, constant lag. A straight cable run would have been ideal, but the on-hand 10m cable couldn’t reach through the house’s odd layout. A wireless repeater plus a short LAN run to the PC got in-game ping stable under 20 ms.

lag

The plan and router were fine. The weak link was the wireless path: the gaming room sat three walls from the main router in an oddly laid-out house, so signal dropped and latency spiked at night.

When a straight cable can’t reach, shorten the wireless hop

The plan (105M HFC) and the router were both fine — the whole problem was the wireless path across three walls. The cleanest fix is always a cable straight to the router, but this house’s layout was unusual (rooms 1 and 2 weren’t even internally connected) and the 10m cable on hand wasn’t long enough. So we shortened the wireless hop instead.

There’s almost always a way to get a stable connection — the difference between options is cost and effort, not whether it’s possible. For gaming, wired is king, but when a full cable run isn’t practical, moving the signal source closer and wiring only the final short leg gets you most of the way there. The goal is a steady, low-latency last hop to the device that actually needs it.
Result

Root cause: three walls of WiFi between the main router and the gaming room, not the HFC 105M plan or the Netcomm router. A wireless repeater near the room plus a short LAN run to the PC brought League of Legends ping to a stable sub-20 ms — and the student reported no more in-game stutter that night.
