Wi-Fi & Routers
Practical help with Wi-Fi coverage, speed, router placement, mesh systems, modems, and connection problems.
This section covers home internet equipment and the wireless network inside the home: routers, modems, mesh nodes, access points, Ethernet, coverage, speed, and devices that refuse to stay connected.
Start With the Symptom
Section titled “Start With the Symptom”Use a specific symptom instead of “the Wi-Fi is bad.” The useful questions are:
- Is the internet slow on one device or every device?
- Is the problem limited to one room?
- Does a wired connection have the same problem?
- Is the connection slow, unstable, or completely unavailable?
- Did the problem begin after moving equipment, changing service, or installing an update?
Those answers separate an internet-service problem from a Wi-Fi coverage problem or a single-device problem.
Router Placement That Usually Helps
Section titled “Router Placement That Usually Helps”Give the router open space. Put it near the center of the area that needs coverage, above floor level, and away from large metal objects, enclosed cabinets, aquariums, microwaves, and dense masonry. Do not stack it under other hot electronics. A router cannot overcome a poor location merely because it has more antennas.
When possible, test speed beside the router and again in the problem room. A large difference points toward coverage or interference. Poor results in both locations point toward the modem, internet service, router capacity, or the test device.
What Belongs Here
Section titled “What Belongs Here”- router placement and Wi-Fi coverage
- 2.4 GHz, 5 GHz, and 6 GHz band choices
- mesh systems and wired backhaul
- modem and router setup
- DNS, DHCP, guest networks, and device connection failures
- deciding whether new equipment will actually fix the problem
