A few practical steps, in order of impact:
-
Quick wins: Move the router higher and as central as possible, away from metal/TVs. Aim antennas perpendicular to the direction you need coverage. For the bedroom device, try the 2.4 GHz SSID (better range) and set 2.4 GHz to 20 MHz channel width on channels 1/6/11. Update router firmware and pick a clean channel.
-
Best fix: Add a second access point/mesh node with wired backhaul. Run Ethernet if you can; if not, MoCA (over coax) is a great alternative. Place the AP near the bedroom.
-
Next best: A mesh system without wires. Put the satellite roughly halfway to the bedroom and ensure a strong link to the main node (tri-band helps).
-
Last resort: Single “extenders.” They work but halve throughput and can be finicky.
If walls are dense (brick/plaster), prioritize wired/MoCA backhaul.
