Re: Deteriorating Broadband speeds

A lot has happened since then !!

All you had to do was confirm that it was totally unloaded.

Do you have another device that you can do another ethernet connection test with ?

Re: Deteriorating Broadband speeds

To rule out big sur I tried on the work macbook running catalina, now getting constant speeds of 944 down 52 up. Well I feel like a right plonker - sorry all and thank you for your help.

I don't speak Mac (like many others on here I suspect), so had to do some googling on "big sur" and "catalina".  Sounds like Apple are as good as Microsoft at messing things up with new OS releases.  I hate Windows 10 and often think the grass might be greener with a Mac, but maybe not. 😉

Re: Deteriorating Broadband speeds

Yes very disappointed, I’d have tested on my Linux laptop but that’s limited to 100mbps as don’t have a USB type A  Ethernet adapter that’s faster. It’s old. Least we’ve figured it out . 🙂

Re: Deteriorating Broadband speeds

Oooohhh that's worrying! My software update keeps reminding me that Big Sur is ready for you ! I had already decided to hold off for a few months to let a few updates come through.

I am off to the uk Mac newsgroup (remember them!?) to ask the guru's on there if anyone else has seen this.  I suspect they will blame the USBc adapters 🙂

Re: Deteriorating Broadband speeds

Yeah - tore my home network apart in the process.....

 

Same usb c adapter on Catalina with latest supplemental updates:-----

Something definately not up to scratch with the usb ethernet drivers on Big Sur, side effect of re-writing Mac OS for dual architecture?

Re: Deteriorating Broadband speeds

Opinion from the Mac-lads in the newsgroup is this....

No, its more likely related to writing the USB Ethernet drivers using DriverKit. Though I thought that'd happened in Catalina.

Which I am not sure I follow as I don't know what DriverKit is/does - but it makes sense that the adapter drivers might not be compatible in BigSur.

Is the USBc-RJ45 an "official" Apple one. If not can you borrow one to try - I have noticed recently that some of my long Anker leads for my iPhones/iPads have stopped working to charge them after an OS upgrade recently. Bought an Apple one and of course it's fine !
