Law Firm Eliminates Wi-Fi Dead Zones, Cuts IT Tickets by 35%

The Problem

A 30-person law firm was struggling with constant Wi-Fi issues:

• Dead zones in conference rooms and remote offices
• Frequent disconnects during client video calls
• Security risk: Guests connected to the same network as internal systems
• IT support overload: 15+ Wi-Fi-related tickets per month

Their existing setup was a hodgepodge of consumer-grade routers and range extenders—fast enough when it worked, but unreliable and insecure.

The Challenge

The firm needed:

• 100% coverage across 3 floors and 8 offices
• Secure segmentation: Guest network isolated from internal systems
• Zero disruption: Deployment during business hours without downtime
• Future-proof: Scalable as they grow to 50+ people

And they needed it done fast—client complaints were mounting.

Our Approach

Week 1: Site Survey & Design

• Wi-Fi heat mapping: Identified dead zones and interference sources
• Network redesign: VLAN segmentation (internal, guest, IoT/printers)
• Hardware selection: Ubiquiti UniFi controller-based Wi-Fi (3 APs)
• QoS policies: Prioritize VoIP and video calls over file transfers

Week 2: Implementation & Testing

• Firewall upgrade: Replaced consumer router with pfSense firewall
• AP installation: Mounted 3 UniFi APs with proper PoE cabling
• VLAN configuration: Internal, guest, and IoT networks segregated
• Testing & optimization: Real-world coverage tests in all offices and conference rooms
• User training: Quick guide on connecting to the new Wi-Fi (internal vs. guest)

The Results

Connectivity

• ✅ 100% coverage: No more dead zones—signal strength > -65 dBm everywhere
• ✅ Zero dropped calls: Video conferences no longer interrupted
• ✅ Faster speeds: 300 Mbps+ on all devices (was 50–100 Mbps with range extenders)

Security

• ✅ Guest network isolation: Clients can’t see internal systems
• ✅ IoT segmentation: Printers and smart devices on separate VLAN
• ✅ Firewall rules: Geo-blocking and threat prevention enabled

Operational Impact

• ✅ 35% fewer IT tickets: From 45/month to 29/month (mostly password resets now)
• ✅ Faster onboarding: New hires connect in < 5 minutes (was 30+ with old setup)
• ✅ Remote management: We can troubleshoot and update APs remotely (no onsite visits)

Tech Stack

• Firewall: pfSense (open-source, enterprise-grade)
• Wi-Fi: Ubiquiti UniFi (3x UAP-AC-Pro access points)
• Controller: UniFi Controller (cloud-hosted for remote management)
• VLANs: Internal (staff), Guest (clients), IoT (printers/devices)
• QoS: Prioritized traffic classes (VoIP > web > file transfers)

Client Feedback

“We went from constant Wi-Fi complaints to zero issues in 2 weeks. Our video calls don’t drop anymore, and we can finally use the conference rooms without worrying about connectivity. Best IT investment we’ve made.”

Timeline

• Week 1: Site survey, design, hardware procurement
• Week 2: Installation, configuration, testing, handover

Total: 2 weeks from kick-off to go-live, with zero disruption to daily operations.

What We Delivered

• Network map and VLAN design
• 3x UniFi access points (professionally mounted)
• pfSense firewall with threat prevention
• Guest network with captive portal
• QoS policies for video/VoIP
• Remote management dashboard
• Config backups and runbooks
• 30 days post-launch support

Key Takeaways

1. Consumer-grade Wi-Fi doesn’t scale: Range extenders create more problems than they solve
2. VLANs are essential: Guest and internal networks should never mix
3. Controller-based Wi-Fi is a game-changer: Centralized management, seamless roaming, real-time monitoring
4. QoS matters: Prioritizing video calls and VoIP prevents dropped connections
5. Fast deployment is possible: With proper planning, you can go from chaos to rock-solid in 2 weeks

Next Steps

After the initial deployment, the firm signed up for our IT Services retainer (€1,200/month) for:

• Monthly network monitoring and optimization
• Helpdesk support (email, phone, remote)
• Quarterly onsite visits for hardware checks
