Okay, I’m at my wit’s end. I recently moved into a two-story townhouse. Near the router downstairs, my 1 Gbps fiber connection works fine and I usually get 700–850 Mbps over Wi‑Fi.
The problem is my home office upstairs, on the opposite side of the apartment. Speeds there can drop to 20–40 Mbps or less.
I’m using the ISP-provided gateway, which is downstairs near the TV where the fiber line comes in. The walls and floor seem pretty thick, and there are lots of neighboring Wi‑Fi networks around me.
I’m looking for real-world fixes that don’t involve a service call.
In short, I’ll tell you right off the bat: your router is set to auto-select a frequency. ISPs are now fond of slapping a single SSID on both bands, but in practice, this is a workaround that leaves your laptop constantly twitching and getting stuck. Band 5 is incredibly fast, but it can’t penetrate walls, while Band 2-4 has a long range, but in apartment buildings, that band is usually completely clogged by neighbors. Go into your router’s admin panel and manually split your network into two different points, like WiFi_2G and WiFi_5G, and then test both directly from your workspace. For Zoom, speedtest numbers are just a matter of comparing notes; you need minimal ping and zero packet loss. If you’re getting a healthy 200 Mbps on 5 GHz but your connection is dropping every five minutes, feel free to switch to a stable 60 Mbps on a 2 GHz router and enjoy seamless calls.
Since you’re using Wi-Fi, you need to check what’s going on in the air. People usually hide their router in a closet or behind the TV, creating a Faraday cage for it, and then get surprised by the lag. Download an airwave scanner (like NetSpot or any WiFi Analyzer) to your smart device. It will immediately show you a heatmap of your coverage and which channels your neighbors are using. If your neighbor’s router is jamming yours on the same frequency, simply move to a free one. And physics still applies: pull the router out of the corner, elevate it, and place it further away from the microwave. Clearer airwaves mean a more stable connection.
Move the router first. If it’s behind the TV, in a cabinet, on the floor, or next to a bunch of electronics, that’s already hurting you. Put it higher and more open if possible. Even moving it from behind the TV to the top of a shelf can make a noticeable difference.
Honestly, for work calls, I’d still consider a wire.
Pull the plug, wait a minute, and then plug it back in. Yes, I know, it’s a cliché from a tired old meme, but this actually clears the DNS cache and forces the device to reconnect to the ISP’s equipment. Just do it.
How old is your gear? If you’re paying for a 1 Gbps plan but are using an ancient modem from 2015, you’re throttling your own speed. Old hardware simply can’t handle modern traffic and becomes a bottleneck for the entire system.
Thanks everyone. I’ll try some of these tips and hope they really help.
