Modern ISP-provided routers, especially Wi-Fi 6 and 6E models, are often more capable than users assume. The real culprit behind poor home Wi-Fi performance is placement — routers tucked behind TVs, in basements, or on floors suffer from signal attenuation caused by metal, concrete, and dense materials. Key advice includes: elevating the router 4–6 feet off the ground, maintaining a 3-foot clear radius around it, avoiding placement behind large electronics like TVs, and using a Cat6a patch cable to reposition it closer to central living areas. Using a free Wi-Fi analyzer app to measure RSSI values helps identify dead zones before and after relocation. Buying a new router or mesh system is often unnecessary when a zero-cost repositioning can unlock the full speeds already being paid for.

A tech support worker responds to a ticket about a printer in HR printing gibberish instead of documents. Upon arrival, he finds a manager using a hair dryer on the printer, which he defuses diplomatically. After basic troubleshooting fails, the team discovers the printer is outputting anonymous HR complaints submitted through a supposedly decommissioned intranet system, leading them to trace the network source of the misdirected print jobs.
NetBox Validation has added a HIPAA Security Rule compliance pack as its ninth framework pack. The pack includes 20 network checks mapped to specific CFR citations, covering network architecture, segmentation, documentation, and resilience. It runs entirely offline against NetBox data before deployment — no SSH or device credentials required. The timing is driven by the proposed 2026 HIPAA Security Rule overhaul, which eliminates the 'addressable' loophole and for the first time mandates explicit network segmentation and a current network map. Organizations will have roughly 240 days to comply once the rule is finalized. The pack is available now in NetBox Cloud Premium tier as part of the public preview.
A DIY passive Ethernet tap built on mini breadboards using RJ45 breakout boards with screw terminals, inspired by the commercial Throwing Star LAN Tap. The device sits inline between a computer and router, copying signals to two monitor-only ports without injecting traffic. Two 220 pF capacitors force 100 Mbps negotiation so only two wire pairs are used, matching what the tap monitors. The build cost roughly €10 and successfully captured 2,769 packets from a smart TV in 7.5 minutes, revealing frequent SSDP NOTIFY broadcasts, mDNS announcements, and IGMP traffic — all with zero CRC errors.
The Internet Service Providers' Association (Ispa) of South Africa released its February 2026 FNO Perception Survey, where ISPs rate the fibre network operators they buy wholesale access from. Six smaller operators — Lightspeed, Open Fibre, Lightstruck, Evotel, Seacom FibreCo, and WeCom — scored between 6.6 and 7.1 out of 10, outperforming most of the eight largest networks. Octotel retained the top spot among the major players at 7.5, while Vumatel showed the biggest year-on-year improvement (+1.0). The survey covered 406 ratings from 45 ISPs across 11 metrics including reliability, technical proficiency, and open-access adherence. Ispa notes the smaller operators' strong results are promising but carry less statistical weight due to fewer raters.
Many routers broadcast all Wi-Fi bands (2.4GHz, 5GHz, 6GHz) under a single unified SSID using 'Smart Connect', which can cause devices to connect to slower bands without the user's knowledge or control. The recommended fix is to split the bands into separate SSIDs with distinct names, giving you explicit control over which devices connect to which band. This helps ensure performance-hungry devices stay on 5GHz, while IoT devices remain on 2.4GHz without congesting the faster band. Splitting SSIDs also makes network issues easier to diagnose, such as spotting when a specific band goes down.
NetBox Labs has made Asset Lifecycle generally available on its Infrastructure Intelligence Platform. The feature extends NetBox's system of record beyond documenting existing infrastructure into managing procurement workflows — covering Bills of Materials, Purchase Orders, Shipments, and Spares as native NetBox objects. BOMs are generated directly from NetBox DCIM designs, with a full auditable trail from approval through installation. The feature targets data center and network teams managing large-scale infrastructure buildouts, multi-site refreshes, and spares management. It integrates via REST API and is positioned as an upstream feed for ERP, ITSM, and finance systems like SAP, Oracle, and ServiceNow rather than a replacement. Available in the Premium tier on NetBox Cloud and NetBox Enterprise.
Early benchmarks of the Linux 7.2 development kernel on an AMD EPYC 8635P (Sorano) server reveal unexpected localhost network performance improvements. TCP throughput and QUIC performance improved noticeably compared to Linux 7.1, while UDP remained unchanged. Sockperf also showed lower latency. A likely explanation is a change in fs/select.c switching the poll implementation from free_page() to the kmalloc() API, which improves scalability. The stress-ng micro-benchmarks confirmed poll performance is several times faster in Linux 7.2. Notably, CPU power consumption on the EPYC 8635P was slightly lower despite the performance gains. These improvements are not AMD-specific and should benefit other hardware as well.

A game config file snippet from a released multiplayer game exposes dangerously user-editable networking parameters, including UDP packet sizes and buffer settings that could be tuned to launch DoS attacks against other players. The config comments range from casual warnings ('don't be a dick') to all-caps profanity-laced pleas not to enable a flag that ignores all variable constraints. A humorous look at the security and design implications of exposing low-level network settings to end users in a shipped product.
