Wi-Fi modules in smart TVs handle wireless streaming, updates, and casting. When they fail, buffering endless, Netflix freezes, and firmware stalls. Nairobi’s congested airwaves and power glitches fry antennas. Prologic-Technologies technicians at Luthuli Avenue diagnose with spectrum analyzers, spotting dead 5GHz bands or weak RSSI. Modules integrate Realtek or Broadcom chips—overheating delaminates solder, cutting range 70%. Replacement restores 802.11ax speeds up to 1.2Gbps.
Loose antennas from shipping cause dropouts. Corrupted NVRAM locks SSIDs. ISP throttling mimics faults—Prologic isolates true hardware issues.
Common Failure Symptoms
No networks detected despite strong home signal. Constant reconnect loops. 2.4GHz works, 5GHz dead—channel interference common in apartments. Casting fails mid-AirPlay. Speed tests cap at 10Mbps on Gigabit plans.
Firmware bricks modules post-update.
Diagnostic Process
Wi-Fi explorers scan channels for interference. Packet captures reveal retransmits. Chip temp probes hit 85°C under load. Boardview files map traces for shorts.
USB Wi-Fi dongle tests rule out TV issues.
Replacement Procedure
Bezel removal exposes mainboards. Hot air lifts BGA modules at 240°C. Flux cleans pads; stencil pastes new balls. IR ovens reflow precisely, avoiding warpage.
Antenna realignment boosts gain 6dBi. EEPROM programs MAC addresses legally.
Firmware flashes via JTAG sync drivers.
Module Types Handled
M.2 form factors slot easily. Mini-PCIe needs adapters. Integrated SoCs require full board swaps. WiGig 60GHz for 4K uncompressed.
Prologic stocks Wi-Fi 6E for future-proofing.
Advanced Solutions
MU-MIMO upgrades handle multiple devices. Beamforming antennas focus signals. Mesh compatibility tests with Google/Amazon ecosystems.
Enterprise WPA3 security flashed.
Service Benefits
4K Netflix without stutter. Gaming lag under 20ms. OTA updates reliable. Costs 80% less than new TVs.

Includes signal strength certification.
Why Prologic Leads Nairobi
Genuine modules—no counterfeits dropping packets. Transparent diagnostics with live demos. Bulk rates for sports bars. Partnerships with Realtek distributors.
Home visits cover Westlands to Eastlands.
Interference Challenges in Nairobi
Crowded 2.4GHz from neighbors. Microwave ovens bleed noise. Thick concrete walls attenuate 5GHz. Prologic channel optimizer apps suggest DFS channels.
Router placement audits free.
Post-Repair Optimization
Band steering enabled. QoS prioritizes streaming. Guest networks isolated. Speed tests verify 500Mbps+.
Annual signal checks prevent degradation.
Prevention Best Practices
Router firmware current. 5GHz preferred for 4K. Reboot monthly clears NVRAM. Avoid 2.4GHz microwaves nearby.
Static IPs stabilize handshakes. Elevate TVs 1m off floors for line-of-sight.
Mesh extenders boost dead zones—Prologic installs TP-Link OneMesh.
Enterprise clients get VLAN tagging for guest isolation.
Over-the-air tests confirm iPerf3 throughputs match specs.
Prologic warranties cover reconnections 12 months.
