Is a repeater the same as a range extender?
Usually, yes. Both receive your router’s signal and re-broadcast it further away. Most single-radio models share airtime, which reduces speed for devices connected through them. More on repeaters
Untangle the terminology
Short answers to the questions readers send most often. Each one links to the guide that explains the idea in depth.
Does a mesh system make my internet faster?
It cannot exceed the speed your provider delivers. It makes that speed reach more rooms more consistently. If a cable plugged into the router is slow, mesh will not help. Test the line first
What does “backhaul” mean?
Backhaul is the link carrying traffic between a mesh node or access point and the router. It can be a dedicated wireless band or, ideally, an Ethernet cable. More on mesh backhaul
What is a good Wi-Fi signal strength in dBm?
Readings between −30 and −67 dBm are good for video calls and streaming. Below about −75 dBm, connections become unreliable. Run a room survey
Why will my smart plug not connect?
Many smart plugs support only 2.4 GHz. If your router combines 2.4 and 5 GHz under one name, setup can fail. Pair with 5 GHz temporarily disabled or use a separate 2.4 GHz network. The 2.4 GHz trap
Are powerline adapters reliable?
They can be, but performance depends on wiring quality, distance and whether both sockets share a circuit. Plug them directly into wall sockets, not extension strips. More on bridges
What is double NAT?
Double NAT happens when two routers each translate addresses. It can break gaming, VPNs and some smart-home apps. Put one device into bridge or access-point mode to fix it.
Do I need Matter or Thread?
Not necessarily. Matter helps devices from different brands work together; Thread is a low-power mesh network used by some Matter devices and needs a border router. Protocol table
How often should I restart my router?
A healthy router should not need routine restarts. If it needs one every few days, treat that as a symptom and check firmware, temperature and the provider line. Fault-finding sequence
