What’s the Best Way to Improve Weak Wi‑Fi in My Apartment?

I’d be cautious with inexpensive repeaters. They’re easy to set up, but they often cut throughput and can be unreliable, especially through several walls. If you need wireless coverage, a properly placed mesh system or wired access point is usually worth the extra cost.

Powerline adapters are another possibility. One unit connects to the router with Ethernet and plugs into a wall outlet, while the second unit plugs in near the computer and provides Ethernet there. They work best when both outlets are on the same electrical circuit, though apartment wiring can make results vary. A wireless bridge is another option: place it where the signal is stronger, then connect the PC to the bridge with Ethernet.

If you can manage it, a long flat Cat6 cable tucked along the baseboards is usually the most dependable and lowest-latency option. It doesn’t have to look messy, and you won’t have to deal with the performance loss or instability that can come with wireless solutions.

A mesh Wi‑Fi system is generally a better choice than a cheap repeater. Place one node near the router and another partway toward the PC, ideally where it still receives a strong signal. A wireless backhaul can reduce speeds somewhat, but it should be more stable than a basic extender.

First, check the basics: how far is the PC from the router, how many walls are between them, and are the Wi‑Fi antennas properly attached to the back of the computer? If the Wi‑Fi card or router is several years old, upgrading either one may also help. Try positioning the router somewhere central and away from large appliances or dense walls.
