UniFi Gateway Failover and WAN Redundancy Explained
How UniFi dual-WAN failover and load balancing work — failover triggers, the two modes, and the gotchas every network engineer hits setting up WAN2.
UniFi Guides
Independent, field-tested configuration guides, explainers, and walkthroughs — written for engineers and serious home-lab operators.
What will I find in the Demarc Networks guides?
Each guide covers a specific UniFi concept, hardware decision, or configuration task in depth — with real network topologies, working command examples, and honest assessments of where UniFi excels and where it falls short. Guides are updated when Ubiquiti ships firmware changes that alter behaviour.
Buying Guide How to Choose a UniFi Access Point
A decision guide to the mainstream UniFi access points — U6 Lite, U6 Pro, and U7 Pro — across Wi-Fi generation, 6 GHz band, uplink speed, and PoE class.
Buying Guide How to Choose a UniFi Protect Camera
A decision guide to the four UniFi Protect G6 cameras — Instant, Bullet, Turret, and PTZ — across form factor, indoor vs outdoor, IR range, power, and storage.
Buying Guide How to Choose a UniFi Gateway in 2026
A decision guide to the UniFi gateway lineup — Cloud Gateway Ultra, Dream Router, and UDM-Pro — across IPS throughput, multi-gig WAN, Wi-Fi, and Protect.
Buying Guide How to Choose a UniFi Switch in 2026
A decision guide to the UniFi switch lineup — Lite 16, Flex 2.5G, Pro 24, and Pro Max 24 — across port count, PoE budget, 1 GbE vs 2.5 GbE, and Layer 3.
Planning PoE Power Budgets Across a UniFi Switch Stack
A PoE switch budget is one number that hides class draw, per-port caps and cable loss. How to size PoE across a UniFi switch stack that has room to grow.
Placing UniFi Protect Cameras: Mounting Height, Field of View, and What Night IR Really Gives You
Mounting height, field of view math, and what UniFi Protect IR actually delivers at night — plus the placements that will never produce usable evidence.
Sizing UniFi Protect Storage: Retention Math for a Multi-Camera Site
Size UniFi Protect storage before you buy: bitrate per resolution, H.264 vs H.265, motion vs continuous recording, RAID overhead, and drive headroom.
UniFi Threat Management: What IDS and IPS Actually Block, and What They Cost in Throughput
UniFi Threat Management explained: what IDS and IPS signatures catch, how sensitivity levels work, and why IPS lowers your gateway throughput ceiling.
Remote Access to a UniFi Network: Teleport, Site Magic, and WireGuard Compared
UniFi ships three remote-access paths. Compare Teleport, Site Magic, and manual WireGuard on routing, DNS, gateway support, and when to use each.
UniFi Switch Uplinks and Link Aggregation: When SFP+, LACP, and 2.5GbE Actually Help
Why bonding UniFi ports never doubles one transfer, how LACP hashes flows, and when a 10G SFP+ uplink or 2.5GbE port is the fix for real congestion.
Configuration UniFi VLANs, Explained — Segmentation Without the Guesswork
Learn how to design, configure, and troubleshoot VLANs in UniFi Network — from the first broadcast domain to inter-VLAN firewall rules.
UniFi Wi-Fi 7 and MLO: When 6 GHz Is Worth the Upgrade, and When It Isn't
Wi-Fi 7 is the default UniFi access point now. What MLO, 320 MHz channels, and the 6 GHz coverage penalty mean for your client fleet, switches, and PoE budget.
Designing Seamless Wi-Fi Roaming Across UniFi Access Points
Design clean device handoffs across a multi-AP UniFi network with Minimum RSSI, band steering, and 802.11k/v/r fast roaming to stop sticky clients.
