My wife teaches ten hours, seven days online. We don't need fast, we need reliable.

SpeedTest ranks 500+ down, 250+ up. Still mole asses. Provider (NT) show up and gave up a bigger fancier router.

Anybody thinks it's Zoom? Or is it my wife's 2019 MacBook Air?

    Ask some of your neighbors what provider is good in your area, they’ll know better than anyone else.

    Maybe have two sources, phone data can be useful for testing. My 3BB can go down for seconds then i switch to AIS data and all good

    Dual WAN router** with a mobile network device as the backup. **Make sure you get one that reliably does WAN failover, many don't. We have a TP-Link TL-ER6020 but it's getting long in the tooth now

We have a TP-Link TL-ER6020 but it's getting long in the tooth now and there are many cheaper units available.

Probably just normal 'internet congestion' though some will no doubt try to blame Russia and Iran the latest boogeymen for any and all worldwide maladies 😋

With regard to you MacBook. 7 years old, your computer is getting a little long in the tooth - if you make money from it, then its worth investing in your tools.

Im just thinking aloud as I have a m1 Mac mini and its getting time to upgrade, along with my iPad, which I teach on and I dont really have as many classes to warrant it.

Have you tried clean my Mac? I use it once in a while to clean out cache items, mail atatchments, if you install apps, then you might have extra language packs and binaries.

I think Onyx is a free alternative.

I dont know what requirements zoom needs, but my internet classes took off, and I would get complaints from parents blaming my connection or wifi for a stuttering image or frozen cam, the tec department just asked me to increase my package, I have 1GB up/down - maybe lower contention ratio on higher priced packages, idk, but the moans stopped and it paid for itself. It may also be the servers or their connections - where are your students?

It is unlikely that the low internet throughput is due to your 7 year old computer. I have an 11 year old iMac and if I have slow internet.... my tests show it's always due to the infrastructure between my house and the rest of the world.

@Crossy 's recommendation is solid if you need a more stable internet connection.

Perhaps you can convince you ISP to allow you to test higher tiers of service if they're available in you area.

Is this to supplement my NT Ipv6 router?

Glad to see a Mac guy on here! Yes, I do all that by running the right OnyX for our OSs, she Monterey and I Ventura using the OpenCore-Patcher on my 2015, the last Steve Jobs design and the last with adequate ports. I won't trade up. It's enough. Our 1GB down/up is slow even though SpeedTests are fine.

Are you aware of all the great Mac services here: Houk & Bank, 4th floor MBK; Dr MacBook at Chidlom; unlimitmac off Latphrao.

Incidentally, I won't be buying a new Mac for a really long time. I'm a shareholder and Timmy donated to Trump's inauguration, dinner and ball room--no thanks. They're just trying to sell you a lot of gear these days, convincing people they need every Apple device in sync. It's a scam.

Yeah, I'm still here, just.

You would plug your existing router into one WAN port and a 3/4/5G gateway device into the other WAN port.

It needs some fiddling with IP addresses and possibly the DMZ but once sorted you should see fairly seamless internet.

10 hours a day, 7 days a week? That is an insane schedule, how does she do ot?

Using the terminal. Ping 8.8.8.8 or 1.1.1.1 during times of slowness and check for packet loss. If you see packet loss, run a traceroute.

Get your wife a Mac with the new M1 to M5 chip. These handle video conferencing so much better than the Intel Macs.

What identifying details has the new router?

Ok, so you are just getting bad performance from a premium line.

Best contact the ISP team and get them to check the routing. If you are continually logging onto a server location they can give you express routing. I'm with 3BB, and they have always been really helpful in the past.

I'm confused! Do you mean Speedtest gives 500 Mb/sec down and 250 Mb/sec up? You only need 5-10 Mb/sec for a reliable Zoom video connection, (I know because I'm doing 6 hours/day, 7 days/week lessons).

I only worked with MS teams earlier. Too many people with cam on wasn't working out well depending on their locations (more than 8).

Only the one who had to show something had it on, the others switched their cam off.

I have to my fibre additionally a pocket wifi (2500bhat/year), wich is reliable, but surely not better than our fibre (AIS) .

Not to mention, keeping the house clean, feeding me, and now living with her demented 87-year old father. W-O-M-A-N! She takes 4-5 hours of sleep.

It would help if you explained what 'mole asses' means!

Do you mean that despite having fast internet, the connection is very slow? Perhaps it's the student's connection or slow infrastructure on the connection path. Run a Tracert command to see where the problem is.

You're funny. Buy local hardware to fix a network issue. 555.

I am assuming its a play on words molasses which is a thick/slow treacle? That said 500+ 250 - isn't exactly slow, but the cheaper end of NT services who now offer 1Gbps as basic entry, tho 500+ should be fine for most needs. The op doesn't mention who the connections are to? The other end of the line could be on slow cell phone data and the route from one end to other could be through all kinds of bottlenecks.

I agree.
Also, if the OP is using Zoom, and the students are (mostly) using phones, maybe ask of them to turn off any virtual backgrounds or background blurring features. Their signal strength could be the issue.

Even with fast 500/250Mbit speeds, Zoom calls can fail due to high packet loss, WiFi interference or latency spikes, or a VPN or security software throttling traffic.

Network and Connection checks:

  • Packet loss: High speeds mean nothing if data packets are dropped along the route. Test using the Zoom connectivity tool to check for loss.

  • Wifi and Internet: A weak Wi-Fi signal or congested channel causes jitter. Switch to a direct wired Ethernet cable.

  • VPN and Security software: Firewalls, deep packet inspection, or strict VPNs often bottleneck real-time UDP traffic. Try temporarily disabling the VPN.

  • Bufferbloat: Heavy background downloads or uploads on other devices can saturate the router's queue, spiking latency.

Computer and App checks:

  • CPU or RAM bottlenecks: Laptops running on battery saver or older hardware throttle performance. Close heavy background apps.

  • Outdated Apps: Running an old version of the Zoom desktop client can cause connection glitches. Update or reinstall the app.

My smallest concern is your hardware. Older hardware like your Mac are quite capable of running Zoom.

Made an APP for my MacBook Pro M1 for testing ping speed to 10 most important nodes, results in screenshot attached.



Speed tests:

1. Speed on WIFI

2. Speed on WIFI after resetting (turning router on/off for 15s)

3. Speed on cable via USB-C dongle


I have NT fiberoptic.

Always check the speed with cable and use cable if possible.

As stated above: Older hardware like your Mac are quite capable of running Zoom.

Router is a 2023 ZTE.

Bufferbloat 450/188, seems fine to me.

Yes, some students don't have hi-speed Internet but the problem seems to be local. Mole asses / Molasses, slow as!

Wonder why NT didn't offer us this speed; we've been customers for eight years.

Yes, sometimes students are on their phones aso and, of course, all of them are overseas.

I have thought about Ethernet, custom-made 50mt line, through living, dining and kitchen to office! Don't use VPN, only Zoom running, browser in background. Damned Zoom won't let you run an outdated version, it disables till updated.

Remarkable your speed on WiFi after router reset dropped significantly!

By speed on cable, do you mean Ethernet?

Do you have a 500Mb or 1Gb package from NT?
