Pick your problem, get the right tools
Choose what you’re seeing and we’ll show you what to try first and which free tools to use.
- Internet is slowPages crawl, downloads drag
- Connection keeps droppingGoes offline, then comes back
- Calls are choppyRobotic, delayed or cutting out
- Can’t reach a site or appOne site fails, others work
- Email problemsBouncing, going to spam, not arriving
- Wi-Fi dead zonesStrong by the router, weak elsewhere
Internet is slow
Slow is usually Wi-Fi, a busy connection or a plan that’s too small, not a broken line.
Try this first
- Run our speed test on a cable, then on Wi-Fi.
- Pause backups, big downloads and streaming, then test again.
- Restart the modem and router in the right order.
Connection keeps dropping
Drops point to an outage, an overheating or failing modem, or weak Wi-Fi at the edge of coverage.
Try this first
- Check whether your provider has an outage.
- Look at the modem lights when it drops: blinking online light means the line itself.
- Test wired. If wired never drops, it’s Wi-Fi.

Read: How to check for an outageCalls are choppy
Voice needs a steady line more than a fast one, so jitter, packet loss and bufferbloat matter most.
Try this first
- Plug the phone or computer into a cable instead of Wi-Fi.
- Run the bufferbloat test while someone uploads a file.
- Check RingCentral status to rule out a service issue.
Can’t reach a site or app
If only one site or app fails, it may be down for everyone, or a DNS or routing problem.
Try this first
- Check if the site or app is down for everyone.
- Try it on your phone with Wi-Fi off.
- Test the site from other cities to spot a routing problem.
Best tools for this
Read: Is it down or just me?Email problems
Most delivery problems are missing or wrong SPF, DKIM or DMARC records, or a blacklist listing.
Try this first
- Run a free email health report on your domain.
- Check that MX and TXT records match your email provider.
- Check Microsoft 365 status if Outlook won’t connect.
Best tools for this
Ask us to fix your email recordsWi-Fi dead zones
Walls, distance and interference weaken Wi-Fi. A better spot, mesh Wi-Fi or wired access points fix it.
Try this first
- Run our speed test next to the router, then in the weak room.
- Move the router up high and out in the open.
- Restart the router, then test again.
Six steps that solve most problems
Try these in order before you call your provider. They take about 15 minutes.
Restart the modem and router
Unplug both, plug the modem in first, wait for it to come online, then the router. How to restart themTest on a cable, then on Wi-Fi
Run our speed test both ways. Fast on a cable but slow on Wi-Fi means coverage, not your plan.Check for an outage

Speedtest by Ookla (opens in a new tab)
speedtest.netThe best-known speed test. Measures download, upload and ping, and lets you choose the test server.
Best for: Comparing against the speed you pay for
What your result meansCompare the result with the speed on your bill. If a wired test keeps coming in well under your plan at different times of day, your provider or your equipment needs a look.
- Free · No sign-up
FAST.com (opens in a new tab)
fast.comA one-click download test from Netflix. Tap “Show more info” for upload speed and latency.
Best for: A 5-second check before streaming or a video call
What your result meansGood for a quick check before a stream. If FAST is slow but the other tests are fine, the problem may be the path to streaming services rather than your whole connection.
- Free · No sign-up
M-Lab Speed Test (opens in a new tab)
speed.measurementlab.netAn open, research-grade test from Measurement Lab (the one Google shows when you search “speed test”).
Best for: An independent result to send your provider
What your result meansA useful independent second opinion to show your provider. Before it runs you have to agree to M-Lab’s data policy, which publishes your IP address with the result.

Waveform Bufferbloat Test (opens in a new tab)
waveform.comMeasures how much your latency jumps while the connection is busy, graded A+ to F.
Best for: Calls that break up when someone uploads or streams
What your result meansA grade of C or lower explains calls and video that stutter whenever someone uploads, backs up or streams. A router with smart queue management (SQM) or QoS usually fixes it, and we can set that up.
Voice & video calls (VoIP)
Is my network ready for business phone calls?
- Free · No sign-up
RingCentral Network Test (opens in a new tab)
networktest.ringcentral.comChecks DNS, ping, connectivity to RingCentral’s call servers and bandwidth, then runs a test call with a MOS call-quality score. The email box is optional.
Best for: Checking a network before or after moving to VoIP
What your result meansMOS runs from 1 to 5: 4 or higher is good, and below about 3.5 callers will notice. “Blocked” relay paths usually mean a firewall is stopping voice traffic. Send us the report and we’ll read it with you.
Your connection, IP address & IPv6
What does the internet see when I connect?
- Free · No sign-up
test-ipv6.com (opens in a new tab)
test-ipv6.comShows your public IPv4 and IPv6 addresses, which provider you appear to be on, and an IPv6 readiness score out of 10.
Best for: Finding your public IP and provider for a support call
What your result meansA score below 10 can explain some sites or apps that load slowly or not at all. The “For the Help Desk” link makes a summary you can send to us or your provider.

Common questions
Why is my internet slow when the speed test looks fine?
Speed is only one part. Weak Wi-Fi, high latency, jitter, packet loss and bufferbloat can all make calls, video and websites feel slow even with a fast plan. Test on a cable, then run the Cloudflare and bufferbloat tests above to see what’s really going on.
What internet speed does my business need?
As a rough guide, plan on 5 to 10 Mbps download and 1 to 3 Mbps upload for each person working online at the same time, plus about 100 Kbps each way for every active VoIP call. Offices that send large files or back up to the cloud need more upload. We can size it for you for free.
What ping and jitter are good for VoIP calls?
For clear calls, aim for latency under 50 ms (under 100 ms is usually fine), jitter under 15 ms (under 30 ms is OK) and no packet loss. Above those numbers callers start to hear choppy or robotic audio.
Why do different speed tests give different results?
Each test uses different servers, methods and routes, and your connection changes from minute to minute. Run two or three tests on a cable, at different times of day, and look at the pattern rather than one number.
Are these tools safe and free to use?
Yes. Every tool on this page is free, runs in your browser and needs no sign-up. They’re run by well-known companies and projects, so they see your IP address like any website does, and some show ads. We don’t get paid to list them.
How can I tell an outage from a problem with my equipment?
Check Downdetector and your provider’s status page first. If there’s no outage, restart the modem and router and test on a cable. If a wired computer still can’t get online, call your provider or us.
What’s included in a free network review?
Send us your test results or call us. We’ll look at your speed, call quality and Wi-Fi setup with you and tell you what we’d fix, with no cost and no obligation.
