I have a weird issue. I’m on a fiber connection with a 100/100 Mbit connection. Using our local testing tools for bandwidth testing, my iMac reports download speeds of around 120 down, but I generally get only 25 to 30 up. This iMac is on Ethernet with a router between my switch and the ISP’s endpoint.
I did the same test using a Lenovo laptop hooked directly into the ISP box too, with very similar results.
So, I used the same test tool on my iPad Pro over WiFi. Imagine my surprise when I suddenly get upload speeds reported as 125 Mbit. This goes through an access point connected to the same switch and router as before. Weird, right?
Not really sure where to continue with troubleshooting here, so wondering if anyone here can explain this behavior? My only idea is messing with the “Hardware” settings on my Ethernet port, but I’m not too keen on this. (Current settings are “Automatic” which translates to 1000baseT, full-duplex, MTU standard (1500) and a tick box enabling AVB/EAV mode, whatever that is…
Thanks for any insights into this mystery!
EDIT: When using the iMac over WiFi, I get very similar results as when using Ethernet.
