Start with the basics: restart both your router and the device you're trying to connect. Unplug the router for 30 seconds then plug it back in. On your device, forget the wifi network and reconnect fresh by entering the password again. This solves about 70% of wifi issues.
If that doesn't work, check whether other devices can connect to the same wifi. If they can, the problem is your specific device. On Windows open Device Manager and update your network adapter driver. On a phone go to Settings > Network and reset network settings.
Also check if you're connecting to the right band. Modern routers broadcast on 2.4GHz and 5GHz with similar names. The 5GHz band is faster but shorter range. Try the 2.4GHz network if you're far from the router.
If nothing works, try connecting to a mobile hotspot. If that works, the problem is definitely your router settings or ISP. Log into your router admin panel (usually 192.168.1.1) and check if your device's MAC address is blocked.

To set up a VPN properly, first decide between a free and paid service. Free VPNs often sell your data, which defeats the whole purpose. Reputable paid options include NordVPN, ExpressVPN, and ProtonVPN. ProtonVPN has a genuinely good free tier.
Once you've chosen a provider, download their app for your device. Most services support Windows, Mac, iOS and Android. Open the app, log in, and connect to a server. For best speeds pick a server geographically close to you. For bypassing regional restrictions pick a server in the target country.
For privacy, make sure the VPN has a kill switch feature — this cuts your internet if the VPN drops, preventing your real IP from leaking. Also check that they have a no-logs policy verified by independent audit.
On mobile, be aware VPNs can drain your battery. Only enable it when you need it, particularly on public wifi where it's most important.

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.
