Wi-Fi Protection & Firewall Setup
Most wireless networks and firewalls are either misconfigured or completely default out of the box. We fix that — so you can connect with confidence.
The Most Common Wi-Fi & Firewall Mistakes
These show up in nearly every home and small business we visit. Any of these sound familiar?
Most routers ship with a default admin password like admin / admin or printed on a sticker. Anyone who gets on your network can access your router settings.
When visitors connect to your main network, they're on the same network as your computers, phones, and smart devices. A compromised guest device can potentially reach everything else.
Router firmware updates patch known security vulnerabilities. Most people install their router once and never update it — leaving known exploits open for years.
Wi-Fi Protected Setup (WPS) is a convenience feature that's been broken for years. It lets attackers brute-force their way onto your network in hours using freely available tools.
Many routers have remote management enabled by default, allowing the admin panel to be accessed from the internet. Unless you specifically need this, it's an unnecessary exposure.
Short, simple passwords are cracked quickly. And when you've shared your Wi-Fi password with a dozen people over the years, you've effectively lost control of who has it.
Frequently Asked Questions
WPA2 and WPA3 are Wi-Fi encryption standards. WPA3 is newer and significantly more secure — it uses stronger encryption and protects against offline dictionary attacks that can crack WPA2 passwords.
If your router supports WPA3, we recommend enabling it (or WPA2/WPA3 mixed mode if some of your devices are older). If your router only supports WPA2, keeping a strong, long password is your best defense.
For most homes and small businesses, a properly configured router firewall is sufficient. The key word is properly configured — most aren't.
A dedicated hardware firewall (like a pfSense or Ubiquiti device) offers more granular control and is worth considering for businesses with sensitive data or multiple employees. We'll give you an honest recommendation based on your actual risk level — not an upsell.
Most routers have a "connected devices" page in their admin panel. You can compare that list to devices you recognize. Free tools like Fing (available as a phone app) also scan your network and show everything connected.
If you see something you don't recognize, don't panic — it's often a device you forgot about. But if you can't account for it, changing your Wi-Fi password immediately removes any unauthorized access.
Hiding your SSID (network name) provides minimal security benefit — any basic scanning tool will still detect the network. It also makes your own life more annoying when connecting new devices.
A strong, unique password does far more for your security than hiding the network name. We generally don't recommend it as a security measure, though there's no harm in doing it.
There's no fixed schedule — but you should change it when: an employee or tenant who had it leaves, you've shared it with a lot of people over time, or you suspect unauthorized access.
If you have a guest network (you should), that password can be changed more freely since guest devices won't need to "remember" it the same way your personal devices do.
DNS filtering works by blocking known malicious domains before your browser can even reach them. Think of it as a blocklist that operates at the network level — covering every device on your network at once.
For businesses with employees browsing the web, it's a highly effective, low-cost layer of protection. Services like Cloudflare Gateway or Cisco Umbrella offer free or affordable tiers. We can set this up for you as part of a network hardening engagement.
