Tips & tricks

Improve your connection

Run a test first to see where you stand — you'll get a personalised, tick-off walkthrough for whatever let you down. This is the full reference: for each metric, the fixes are ordered top-to-bottom, free ones first, contacting your ISP last.

Download

How fast you pull data in — streaming, loading, downloads.

  1. Pause the big data users first: stop 4K streams, console/game updates and cloud photo backups, then re-test.Free · try firstOne line is shared, so a single 4K stream or update download can eat most of your speed.
  2. Switch off any VPN or proxy on this device, then run the test again.Free · try firstA VPN routes all traffic through a distant server and can easily halve your download speed.
  3. Power-cycle the router: unplug for 30 seconds, plug back in, wait for a solid connection light.Free · try firstRouters accumulate faults over weeks of uptime — a clean restart clears them.
  4. Stand within sight of the router and join its 5 GHz network (often named '-5G' or '-5GHz').A setting to change5 GHz is far faster than 2.4 GHz up close and less crowded by neighbors’ Wi-Fi.
  5. Test wired with a Cat 5e or Cat 6 cable, and replace any Cat 5 or a 5+ year-old router.HardwareCat 5e and Cat 6 carry gigabit — plain old Cat 5 tops out at 100 Mbps.
  6. If a wired test beside the router stays well below your plan's rated speed, contact your ISP.Ask your ISPIf it's slow even on a cable, the problem is on their side of the wall.

Upload

How fast you send data out — calls, posting, backups.

  1. Pause cloud backups and photo sync (OneDrive, Google Drive, iCloud Photos, Dropbox) on all devices, then re-test.Free · try firstUpload is a narrow shared lane, and one background photo or video backup can fill it entirely.
  2. Disconnect any VPN and run the test again.Free · try firstUpload usually takes the biggest hit from a VPN's detour.
  3. Get within sight of the router and join its 5 GHz network (SSID often ends in '5G').Free · try firstYour device transmits at far lower power than the router, so weak Wi-Fi hurts upload first.
  4. In Zoom/Teams/Meet video settings, turn off 'send HD video' (or 'HD').A setting to changeOutgoing HD video is most people's single heaviest upload, and standard quality needs a fraction of it.
  5. Connect the device to the router with a Cat5e or better ethernet cable for big uploads.HardwareWired delivers whatever upload your plan actually has.
  6. If upload stays low on cable or DSL, ask your ISP about a full-fiber (FTTP) plan.Ask your ISPCable and DSL are built download-heavy. Fiber plans often upload as fast as they download.

Latency

The round-trip delay (ping) — what makes things feel instant.

  1. Re-run the test and note whether ping is only high to distant servers, not the nearest.Free · try firstDistance adds delay nothing can remove. High ping to a nearby server is the suspicious kind.
  2. If you're connected to a VPN, disconnect it and retest.Free · try firstEvery packet takes the long way round while a VPN is on.
  3. Pause big downloads, uploads, cloud/photo backups and 4K streams on every device, then retest.Free · try firstA full line makes every packet wait in a queue. Free the line and the queue drains.
  4. Plug into the router with an ethernet cable (or stand right beside it) and retest.Free · try firstIf the wired number is good, Wi-Fi was your problem.
  5. Reboot the router, then enable QoS/Smart Queue Management (SQM) in its settings and use 5 GHz nearby.A setting to changeSQM stops big transfers from inflating your ping, and 5 GHz is the less crowded band.
  6. If ping stays high both wired and to a nearby server, contact your ISP about a line fault.Ask your ISPAt that point the delay lives on their network, and only they can fix it.

Jitter

How much the delay wobbles — the cause of choppy calls.

  1. Pause background uploads and downloads: cloud sync, backups, OS updates, plus other devices streaming or gaming.Free · try firstBursts of traffic make each packet wait a different amount. That variation is jitter.
  2. Move closer to the router or clear walls and obstacles until your signal is near full.Free · try firstWeak signal makes Wi-Fi retransmit dropped packets, and each retry adds unpredictable delay.
  3. If you can, connect the device to the router with an Ethernet cable (Cat5e or Cat6).A setting to changeSharing the airwaves is the biggest source of jitter. A cable skips it entirely.
  4. On Wi-Fi, join the 5 GHz band — if you’re stuck on 2.4 GHz, set the router channel to 1, 6, or 11.A setting to changeFewer collisions with the neighbors keeps packet timing steady.
  5. In router settings, enable Smart Queue Management (SQM), QoS, or the anti-bufferbloat option.A setting to changeQueue management keeps big transfers from making everything else wait.
  6. If jitter stays high wired with nothing else running, contact your ISP and report 'high jitter / unstable latency'.Ask your ISPWobble that survives a wired, quiet test is coming from outside your home.

Packet loss

The share of packets that never arrive — glitches and drops.

  1. Re-run the test with your device plugged straight into the router by ethernet cable.Free · try firstIf the loss disappears on a cable, the fault was your Wi-Fi. That one result settles where to look.
  2. Power-cycle the router: unplug 30 seconds, then reseat the power, ethernet, and wall coax/phone cables.Free · try firstA restart clears stale router state, and a loose or corroded connector silently drops packets.
  3. On Wi-Fi, move within sight of the router, away from microwaves, cordless phones, and thick walls.Free · try firstDistance, walls, and interference corrupt packets in flight, and damaged packets get thrown away.
  4. In the router's admin page (address on its label), move Wi-Fi to 5 GHz — on 2.4 GHz, pick channel 1, 6, or 11.A setting to change5 GHz is far less congested, and those 3 are the only non-overlapping 2.4 GHz channels.
  5. Replace any worn cable with Cat5e-or-better ethernet, and add a mesh node or wired access point for dead zones.HardwareA worn cable or a weak far room never holds a clean connection for long.
  6. If loss stays high even when wired, contact your ISP and report steady packet loss on ethernet.Ask your ISPSteady loss on a wired connection points at the line itself, and the line is theirs.

Steadiness

Whether your speed holds, or surges and collapses — long downloads, streams, and backups feel the swings.

  1. Pause everything else on the connection — 4K streams, game and OS updates, cloud sync on every device — then re-test.Free · try firstCompeting traffic arrives in bursts, and every burst carves a notch out of your rate. A line that steadies with nothing else running points at your own household, not the ISP.
  2. Re-run the test plugged into the router by ethernet cable.Free · try firstWi-Fi rates lurch with interference and signal strength — if the swings vanish on a cable, they were the airwaves, not the line.
  3. Power-cycle the modem and router: unplug both for 30 seconds, start the modem first.Free · try firstHardware partway into failing often produces exactly this shape — bursts, then nothing, then bursts again.
  4. On Wi-Fi, move to the 5 GHz band — and if you are stuck on 2.4 GHz, set the channel to 1, 6, or 11.A setting to changeA crowded band makes speed come and go as every nearby network takes turns transmitting.
  5. Reseat the wall coax, phone, or fiber connectors and replace any worn or kinked cord.HardwareA loose or corroded connector drops the line for moments at a time, which reads as speed that surges and stalls.
  6. If a wired, quiet test still surges and stalls — especially at evening hours — report the pattern to your ISP with the times it happens.Ask your ISPSpeed that collapses at busy hours on a clean wired line is congestion or a line fault on their side of the wall.

Bufferbloat

Latency that spikes when the link is busy — lag during downloads and uploads.

  1. Pause big background transfers — Windows updates, Steam/console downloads, cloud photo and file sync — during calls and games.Free · try firstBufferbloat only appears when the link is maxed out — freeing bandwidth clears the spike instantly.
  2. Re-test wired via an Ethernet cable to the router to check if the spikes remain.Free · try firstIf it's still bad while wired, the buffer is in the router or ISP line, not Wi-Fi.
  3. Turn on your router's queue management: SQM, Adaptive QoS (Asus), or Dynamic QoS (Netgear).A setting to changeThese keep the queue short, so your ping barely rises even at full speed.
  4. If there’s no auto option, enable QoS and cap both download and upload to ~85–90% of measured speed.A setting to changeThe cap moves the queue into your router, where it's managed. The upload cap matters most.
  5. If your router has none of these, replace it with an SQM-capable model (e.g. OpenWrt-compatible).HardwareBudget routers simply don't have the feature.
  6. Only if spikes persist while wired with SQM on, ask your ISP about bufferbloat on their line.Ask your ISPSome bloat lives in the modem or ISP gear you can't touch, and a faster plan won't fix it.
