# MySygnal > Free internet speed test with bufferbloat grading, a WiFi coverage > simulator, a mesh-vs-repeater comparison lab, and a WiFi channel advisor. > Everything runs in the browser; nothing you draw or measure is uploaded. ## Tools - Speed Test (https://mysygnal.net/): download/upload throughput, latency and bufferbloat grading against a real physics-informed model. - Coverage Mapper (https://mysygnal.net/coverage-mapper): draw a floor plan, place a router, and simulate real WiFi coverage with a multi-wall propagation model. - Mesh Lab (https://mysygnal.net/mesh-lab): compare one router, router + repeater, and a wired two-node mesh on the same floor plan. - Channel Advisor (https://mysygnal.net/channel-advisor): a five-question quiz that recommends a WiFi channel and width for your router, your country's regulatory domain, and your household. ## Guides Ten long-form guides (English; six further translations linked from each page). Each one funnels to exactly one of the tools above. - Bufferbloat, Explained: Why Fast WiFi Still Lags: https://mysygnal.net/guides/bufferbloat-explained Why a queue that is too big, not a slow plan, is the real reason your connection lags under load — and the one setting that actually fixes it. - Why WiFi Is Slow in Just One Room: https://mysygnal.net/guides/why-wifi-is-slow-in-one-room Signal bars and speed are not the same thing — what one wall costs your WiFi, why the wrong wall costs more, and how to diagnose it without walking the house. - WiFi Channel Congestion, and How to Pick a Clean One: https://mysygnal.net/guides/wifi-channel-congestion What channel congestion actually is (airtime, not bandwidth), why only three 2.4 GHz channels are usable, and how to pick a clean one in ninety seconds. - Mesh vs. Extender vs. Repeater: What Actually Differs: https://mysygnal.net/guides/mesh-vs-extender-vs-repeater The three things people mean by 'boosting WiFi', the halving problem behind all of them, and why a wired backhaul is the one upgrade that avoids it entirely. - Where to Put Your Router (and Where Never To): https://mysygnal.net/guides/where-to-put-your-router Why the floor and the corner are the two worst router spots, why height matters more than people think, and what angling the antennas actually does. - 2.4, 5 and 6 GHz: The Honest Trade Between Them: https://mysygnal.net/guides/wifi-bands-24-5-6-ghz Range against speed, and what WiFi 6E and 7 actually changed — plus when splitting your network into separate band-specific SSIDs is still the right call. - Why a VPN Slows You Down (and When It Doesn't): https://mysygnal.net/guides/why-a-vpn-slows-you-down The three real costs of running a VPN — encryption, the detour, the exit node — and why the detour, not your CPU, is almost always the one hurting you. - How Much Internet Speed You Actually Need: https://mysygnal.net/guides/how-much-internet-speed-you-need Real per-activity numbers for streaming, calls, gaming and downloads, added up for a real household — and where more speed genuinely stops helping. - How to Actually Read a Speed Test: https://mysygnal.net/guides/reading-a-speed-test What download, upload, idle and loaded latency, jitter and packet loss each mean — and exactly how the Sygnal Score turns all six into one honest number. - Is It Your WiFi or Your Internet? A Three-Minute Triage: https://mysygnal.net/guides/is-it-your-wifi-or-your-internet One test splits the problem in half: run it over Ethernet, and you'll know within three minutes whether it's your WiFi, your ISP, or a real outage. ## Router models 47 model pages, each with real specs, band capabilities, and channel guidance derived from the Channel Advisor's own logic. Hub: https://mysygnal.net/routers. English and Spanish only — the two languages this project can vouch for on hardware specifics — so a reader in any other language is linked to the English page rather than a machine-translated spec sheet. (M8 review: this sentence used to read "see /api-docs for why". /api-docs documents the speed-test endpoints and says nothing about router-page locales, so an agent following that pointer found no answer.) - TP-Link Archer AX55: https://mysygnal.net/routers/tplink-archer-ax55 - ASUS RT-AX58U: https://mysygnal.net/routers/asus-rt-ax58u - Netgear Nighthawk R7000: https://mysygnal.net/routers/netgear-r7000 - Ubiquiti UniFi U6+: https://mysygnal.net/routers/ubiquiti-u6-plus - Amazon Eero 6+: https://mysygnal.net/routers/eero-6-plus - TP-Link Deco X20: https://mysygnal.net/routers/tplink-deco-x20 - Google Nest Wifi Pro: https://mysygnal.net/routers/google-nest-wifi-pro - Xiaomi Router AX3000: https://mysygnal.net/routers/xiaomi-ax3000 - Linksys MR7350: https://mysygnal.net/routers/linksys-mr7350 - TP-Link Archer BE550: https://mysygnal.net/routers/tplink-archer-be550 - ISP router (WiFi 5 / AC): https://mysygnal.net/routers/isp-generic-ac - ISP router (WiFi 6 / AX): https://mysygnal.net/routers/isp-generic-ax - TP-Link Archer C7: https://mysygnal.net/routers/tplink-archer-c7 - TP-Link Archer AX73: https://mysygnal.net/routers/tplink-archer-ax73 - TP-Link Archer AXE75: https://mysygnal.net/routers/tplink-archer-axe75 - TP-Link Deco X55: https://mysygnal.net/routers/tplink-deco-x55 - TP-Link Deco XE75: https://mysygnal.net/routers/tplink-deco-xe75 - TP-Link Deco BE85: https://mysygnal.net/routers/tplink-deco-be85 - TP-Link Archer BE800: https://mysygnal.net/routers/tplink-archer-be800 - ASUS RT-AC68U: https://mysygnal.net/routers/asus-rt-ac68u - ASUS RT-AX86U: https://mysygnal.net/routers/asus-rt-ax86u - ASUS RT-AX88U: https://mysygnal.net/routers/asus-rt-ax88u - ASUS ROG Rapture GT-AX11000: https://mysygnal.net/routers/asus-gt-ax11000 - ASUS RT-AXE7800: https://mysygnal.net/routers/asus-rt-axe7800 - ASUS RT-BE88U: https://mysygnal.net/routers/asus-rt-be88u - ASUS ZenWiFi XT8: https://mysygnal.net/routers/asus-zenwifi-xt8 - ASUS ZenWiFi ET8: https://mysygnal.net/routers/asus-zenwifi-et8 - Netgear Nighthawk R6700: https://mysygnal.net/routers/netgear-r6700 - Netgear Nighthawk RAX50: https://mysygnal.net/routers/netgear-rax50 - Netgear Nighthawk RAX80: https://mysygnal.net/routers/netgear-rax80 - Netgear Nighthawk RAXE500: https://mysygnal.net/routers/netgear-raxe500 - Netgear Orbi RBK752: https://mysygnal.net/routers/netgear-orbi-rbk752 - Netgear Orbi RBKE963: https://mysygnal.net/routers/netgear-orbi-rbke963 - Ubiquiti UniFi AC Lite: https://mysygnal.net/routers/ubiquiti-ac-lite - Ubiquiti UniFi U6-LR: https://mysygnal.net/routers/ubiquiti-u6-lr - Ubiquiti UniFi U6 Pro: https://mysygnal.net/routers/ubiquiti-u6-pro - Ubiquiti UniFi U7 Pro: https://mysygnal.net/routers/ubiquiti-u7-pro - Amazon Eero 6: https://mysygnal.net/routers/eero-6 - Amazon Eero Pro 6E: https://mysygnal.net/routers/eero-pro-6e - Amazon Eero Max 7: https://mysygnal.net/routers/eero-max-7 - Google Nest Wifi: https://mysygnal.net/routers/google-nest-wifi - Xiaomi Redmi Router AX6000: https://mysygnal.net/routers/xiaomi-redmi-ax6000 - Xiaomi Router BE3600: https://mysygnal.net/routers/xiaomi-be3600 - Linksys EA7500: https://mysygnal.net/routers/linksys-ea7500 - Linksys Velop MX4200: https://mysygnal.net/routers/linksys-velop-mx4200 - ISP router (WiFi 4 / N, 2.4 GHz only): https://mysygnal.net/routers/isp-generic-n - ISP router (WiFi 7 / BE): https://mysygnal.net/routers/isp-generic-be ## API The speed-test endpoints are unauthenticated, uncorsed by design, and already callable from a script, an agent, or an LLM tool — full documentation, worked examples and the rate-limit arithmetic at https://mysygnal.net/api-docs. - GET https://mysygnal.net/api/speed/ping — unmetered - GET https://mysygnal.net/api/speed/meta — unmetered - GET https://mysygnal.net/api/speed/down — 600 tokens/hour/IP - POST https://mysygnal.net/api/speed/up — 600 tokens/hour/IP Shared rate-limit bucket (down/up): 600 tokens/IP, refilling one token every 6 seconds — roughly 10 full tests/hour. Largest single request either endpoint serves or accepts: 100 MB. ping/meta are unmetered. Machine-readable: https://mysygnal.net/openapi.json (OpenAPI 3.1) and https://mysygnal.net/.well-known/api-catalog (RFC 9727 API catalog, linking the OpenAPI document, this page's https://mysygnal.net/api-docs, and a health check at https://mysygnal.net/api/health). Authentication: https://mysygnal.net/auth.md — the API is anonymous by design; no keys, no OAuth. ## Markdown Every guide, every router page, /api-docs and the homepage also answer in clean markdown instead of HTML: send `Accept: text/markdown` and get that page's markdown back, with an `x-markdown-tokens` header (a ceil(bytes/4) estimate) and `Vary: Accept`. Or skip negotiation entirely and fetch the `/md/…` file directly — same locale prefix as the page it mirrors, e.g. https://mysygnal.net/md/guides/bufferbloat-explained.md, https://mysygnal.net/md/es/guides/bufferbloat-explained.md, https://mysygnal.net/md/api-docs.md, https://mysygnal.net/md/index.md. Pricing, account, privacy, terms and score are not mirrored (transactional or noindex). ## Languages MySygnal ships in 7 languages.
