To protect your privacy online the most impactful thing you can do is use a password manager. Most people reuse passwords across sites, which means one breach exposes everything. Bitwarden is excellent and free. 1Password is worth paying for.

Enable two-factor authentication everywhere you can, especially email, banking, and social media. Use an authenticator app (Google Authenticator or Authy) rather than SMS, since SMS can be intercepted.

For browsing, use Firefox or Brave instead of Chrome. Install uBlock Origin as an ad blocker — it blocks trackers, not just ads. Use DuckDuckGo instead of Google if privacy matters to you.

Be careful what you share on social media. Your date of birth, phone number, home city, and workplace are enough for identity theft. Review your privacy settings on Facebook, Instagram and Twitter regularly.

For sensitive communications, Signal is the gold standard for encrypted messaging.

Slow wifi is usually either a distance problem, a congestion problem, or a hardware problem. Let me break these down.

Distance: wifi signal degrades fast through walls. If you're more than two rooms away from your router, consider a wifi extender or mesh system. Mesh systems like Google Wifi or TP-Link Deco are worth it for larger homes.

Congestion: if everyone in your area uses 2.4GHz wifi, you'll experience interference. Switch to 5GHz if your router supports it — it's faster and less congested in apartment buildings.

Hardware: routers older than 4-5 years often struggle with modern demands. If your router is that old, it may be time to upgrade. Look for WiFi 6 routers — they handle multiple devices much better than older standards.

Also check how many devices are connected to your network. Every device sharing bandwidth reduces your speed. Disconnect devices you're not using.
