Wi-Fi Extender vs Mesh

Wi-Fi Extender (cheap, simple)

$30-80 device that plugs into a wall outlet. Catches your existing Wi-Fi, rebroadcasts.

• Pros: Cheap, fast install (10 minutes).
• Cons: Halves the speed at the extender. Creates a SECOND network name. Phone may stay on weak primary instead of switching.
• When to use: One small area not getting signal (back bedroom, garage). Budget under $100.

Picks: TP-Link RE315 ($30), Netgear EX3700 ($40).

Mesh System (premium, smooth)

$150-400 set of 2-3 units. Replaces your existing router. Creates ONE network with full coverage.

• Pros: Same network everywhere. Full speed. Auto-switches as you walk.
• Cons: 3-5x more expensive than extender.
• When to use: Whole-home coverage problems. Big house. Multiple dead zones.

Picks: eero 6+ 2-pack ($200), TP-Link Deco X20 3-pack ($170), Google Nest Wifi Pro 3-pack ($300).

Powerline adapter (alternative)

Sends internet through your home\'s electrical wiring. $80-150 for a kit. Plug one in near router, one in dead zone.

• Pros: Bypasses Wi-Fi entirely. Wired-quality speeds.
• Cons: Older homes with split electrical panels often don\'t work.
• When to use: Smart TV in basement that needs hard internet.

Free fixes to try first

• Move router — central in home, off floor, away from microwave/big appliances.
• Restart router — unplug 30 sec, plug back. Fixes 50% of complaints.
• Update firmware — log into router admin page, click "Check for updates".
• Check Wi-Fi channel — auto might be jammed by neighbors. Try manually setting channel 1, 6, or 11 on 2.4GHz.
• Replace 8-year-old router — new $80 router beats old $200 router.
