What Is Gateway & WiFi Testing?
Gateway/CPE (Customer Premises Equipment) devices — home routers, cable modems, DSL modems, and set-top boxes — are the backbone of every broadband connection. This course trains you to systematically validate every layer of a gateway: hardware bring-up, networking stack (IPv4/IPv6), WiFi radio, security policies, management protocols, and performance under real-world load. Graduates are immediately productive in roles at OEMs (Arris, CommScope, Sagemcom), telecom operators (Comcast, Airtel, BSNL), and WiFi chipset companies (Qualcomm, Broadcom, MediaTek).
Complete WiFi Coverage
From 802.11b legacy to the latest WiFi 6E (802.11ax) — OFDMA, MU-MIMO, 6 GHz band, BSS colouring, and target wake time (TWT) validation.
Security-First Testing
WPA3-SAE, 802.1X/EAP-RADIUS, Protected Management Frames (PMF), WPS vulnerability testing, and firewall rule validation — securing the last-mile device.
Performance Benchmarking
iPerf3 TCP/UDP throughput, RFC 2544 framing, latency & jitter under multi-client stress, MIMO spatial stream validation, and real-world range testing.

Curriculum shaped by engineers from Comcast, Charter, Arris, and RDK-B contributors. Every lab mirrors actual carrier acceptance testing.
Python Automation Track
Dedicated automation module using Python + Robot Framework to build regression suites — a skill that moves your resume to the top of the pile.
Certification-Prep Support
Aligned with WiFi Alliance Certified Network Associate (WCNA) and CableLabs DOCSIS test specifications. Study guides provided.
100% Placement Support
Dedicated placement team, mock interviews, resume review, and active tie-ups with broadband OEMs, ISPs, and embedded product companies.
Lifetime Lab Access
Alumni retain remote lab access to continue practicing on real devices, upgrading firmware, and running new test scenarios indefinitely.
10-Week Curriculum
Six progressive modules taking you from gateway architecture through WiFi radio, security, feature validation, performance testing, and automation — with real CPE lab work throughout.
Understand the anatomy of a CPE gateway — hardware, software stack, WAN/LAN interfaces — and build fluency with the IP networking layer it rides on.
- CPE/gateway hardware: SoC, radio chips, flash, RAM, Ethernet switch
- Linux networking stack on embedded devices: /proc/net, ip, ifconfig
- WAN modes: DHCP WAN, PPPoE, IPoE, static IP configuration & testing
- IPv4/IPv6 dual-stack: RA, SLAAC, DHCPv6-PD, 6rd, DS-Lite testing
- DHCP server/relay/client testing with scope inspection
- DNS proxy/resolver validation and split-DNS scenarios
- NAT44 / NAT64 traversal and hairpin NAT testing
- Lab: bring up a CPE, trace WAN negotiation with Wireshark
Deep-dive into the IEEE 802.11 protocol family and the RF environment — everything a tester needs to understand before touching a WiFi spec sheet.
- 802.11 a/b/g/n/ac/ax: PHY rates, MIMO, channel widths (20/40/80/160 MHz)
- WiFi 6 / 6E: OFDMA uplink/downlink, MU-MIMO, BSS colouring, TWT
- 2.4 GHz / 5 GHz / 6 GHz band characteristics and channel planning
- BSSID / SSID management, hidden SSID, guest SSID isolation testing
- Beacon frames, probe request/response & association lifecycle (Wireshark)
- DFS channel compliance and radar detection testing
- RSSI, SNR, noise floor measurement and coverage mapping
- Lab: WiFi Analyzer + Ekahau site survey; channel overlap testing
Validate the full security stack of a WiFi gateway — from legacy WEP through modern WPA3-Enterprise — plus firewall and intrusion scenarios.
- WEP / WPA-TKIP / WPA2-CCMP / WPA3-SAE: handshake capture & validation
- WPA3-Enterprise: 802.1X / EAP-TLS, EAP-PEAP with FreeRADIUS integration
- Protected Management Frames (PMF / 802.11w): mandatory in WPA3
- WPS (PIN & PBC modes): registration protocol and vulnerability testing
- Captive portal and guest network isolation validation
- Firewall rules: stateful SPI, port forwarding, DMZ, ALG testing
- Parental controls: URL filtering, time scheduling, device blocking
- Lab: 4-way WPA3 handshake capture; rogue AP detection with Wireshark
Test the rich feature set of a modern gateway — QoS, TR-069 provisioning, bandwidth management, and advanced WiFi mobility features.
- TR-069 / CWMP: ACS connection, firmware upgrades, parameter get/set (TR-181)
- TR-181 data model: WiFi, routing, firewall, VoIP object tree validation
- QoS: DSCP marking, WMM (802.11e), traffic shaping for voice & video
- Band steering: 802.11k neighbour reports, 802.11v BSS Transition Management
- Fast roaming: 802.11r FT (pre-auth, over-DS), OKC testing
- Mesh networking: EasyMesh (IEEE 1905.1), backhaul link validation
- VLAN on gateway: WAN VLAN tagging, LAN segmentation, IPTV VLAN
- Lab: TR-069 ACS-driven firmware upgrade; QoS priority validation with iPerf3
Benchmark gateway hardware and WiFi radio performance — from single-stream Phy rate to multi-client stress and real-world range — the way carriers do it.
- iPerf3: TCP/UDP throughput, reverse mode, parallel streams, bitrate limiting
- RFC 2544 framing (throughput, back-to-back, latency, frame loss) concepts
- Latency & jitter: ping, hping3, D-ITG traffic generator benchmarks
- Multi-client stress: 50+ simultaneous WiFi clients, NAT table saturation
