Deep dives into networking technology, home theater gear, and audio. We go beyond the spec sheet.
WiFi 7's Multi-Link Operation promises simultaneous connections across multiple bands. But most consumer hardware only supports the restricted NSTR form. Here's what the spec sheet doesn't tell you.
WiFi 7 brings real improvements over WiFi 6E — 320 MHz channels, 4K-QAM, and Multi-Link Operation. But for most households, the question isn't capability. It's timing. Here's how to decide.
Your ISP's combo box isn't a work-grade network. Here's how to build a home setup that handles video calls, VPNs, and multiple users without dropping packets at 2pm on a Tuesday.
OFDMA is one of the most consequential improvements in modern WiFi — and also one of the most poorly explained. This breaks down what it does, why it matters, and when you'll actually feel the difference.
In 2026, WiFi 6E mesh systems have dropped into the under-$200 bracket. The TP-Link Deco XE75 leads with dedicated 6 GHz backhaul; the Eero 6+ wins on setup simplicity. Here's how to pick the right one.
HDMI ARC is the right connection for most setups — one cable, one remote. If your devices support eARC, you get lossless Dolby Atmos. Here's the full guide for every TV and soundbar scenario.
The FCC's foreign router ban took effect March 23, 2026. Your existing router is fine. New imports are blocked except for a short list of conditional approvals. Here's the buyer's guide.
MoCA 2.5 turns the coax already in your walls into a 2 Gbps wired backbone — single-digit latency, 10-minute install, far cheaper than pulling new Ethernet. Here's exactly what to buy, what to check first, and the splitter and PoE filter gotchas that sabotage most installs.
ARC was designed for stereo and Dolby Digital 5.1; eARC is the only HDMI return-channel spec that carries lossless TrueHD Atmos and DTS:X from a modern TV back to a soundbar or AVR. Here's exactly what each one passes, what you need on both ends, and the cable + format settings that account for most failed installs.
"HDMI 2.1" on a spec sheet is no longer a guarantee — the label can ship on a port that implements as little as a single feature. Here's what FRL signaling, 4K120, VRR, ALLM, QMS, dynamic HDR pass-through, and eARC actually require on both ends of the cable, which 2024–2026 TVs and consoles deliver them, and how to verify your link is really negotiating 4K120.
Cat6a is the right answer for almost every in-wall run; Cat6 is fine for short patch cables; Cat7 is a marketing label TIA never ratified for RJ45; Cat8 is purpose-built for short data-center patches, not your walls. Here's what each category actually delivers and which one belongs where.
Dolby Vision has the deepest content library and the broadest TV support outside Samsung. HDR10+ is technically excellent but thin on content. HDR10 is the universal floor. Here's what each format actually does and which one to prioritize when buying a TV in 2026.
Mesh nodes, game consoles, and 4K streamers all want a wired uplink. Ethernet, MoCA 2.5, and Powerline each promise to deliver — but only one is right for your house. Real throughput, real latency, and the box-rating gap that wrecks Powerline installs.
Dialogue is mixed quiet for calibrated theaters, then crushed by lossy streaming codecs and 8-watt TV drivers firing into the floor. Three free fixes solve 70% of complaints in 10 minutes; the rest need real center-channel hardware.
2.5GbE rides existing Cat5e copper for under $80 and fits 95% of homes. 10GbE earns its place only for a NAS-to-workstation pair — and even then, SFP+ DAC beats 10GBASE-T copper on cost, power, and heat. Here's the four-scenario buying guide.
In-ceiling speakers are the reference for dedicated theater rooms. Dedicated wall-mounted height speakers are the best compromise for most living rooms. Upfiring modules work when the ceiling cooperates. Soundbars get you Atmos with the lowest effort. Here is the honest hierarchy and a decision tree for your room.
A second subwoofer does not make bass louder — it makes bass even at every seat. Here is the room-mode physics, the placement patterns that actually work, when dual subs are worth the money, when they are not, and what to buy at every budget.
Dirac Live is the most capable, Audyssey MultEQ XT32 with MultEQ-X gets close for half the money, and YPAO is the most forgiving. Here is what each system actually does, where each one falls short, and which receivers ship with which version.
If you have a subwoofer and a normal-sized room, bookshelves on good stands deliver 90% of what a floorstander does for half the price. Towers win when you're running 2.0 stereo without a sub, your room is over 250 sq ft, you cross the sub below 80 Hz, or you listen loud in a big space.
DFS channels doubled your 5 GHz airspace in exchange for one rule: your router has to go silent the moment it hears radar. Here's what that actually looks like, the symptoms it causes, and when to turn it off.
