Internet speeds slower than on Win10

Are you running any AV Software that does real time scanning? That will slow a connection dramatically on Macs. If so, uninstall it. They are useless.

AV Software = anti-virus software.

I'll be a little picky here

-- same cable

--same router port

for both devices?

Take what cable and port you use for windows. pull out cable from windows box and plug into mac.

Well, if you have the brea$.

try a "thunderbolt gigabit ethernet adapter"

Thunderbolt to Gigabit Ethernet Adapter - Apple

Re: 1Gbps ethernet speed changed to 100Mbps

However, I'm feeling it's a software issue. No idea what.

I very much doubt your using Windows 10 tools to measure speed: it might lie. You'd have to test downloads on either machine alternately to settle in a number by hand.

Apple's 1000baseT is built into the Intel Chipset, your Apple uses %100 intel board and chips (worth paying more for - dell does not do this), which is simply speaking: the best 1000baseT your going to likely ever see. It's speed is on Apple's specifications.

Apples networking stack is excellent.

So there are two issues. #1 you said your ISP measured speed but not the speed on your Apple. So how can we answer if that is NOT running top speed? Perhaps the imac does run at that speed.

another issue is you didn't show ALL your network connections. do you have multiple connections to your modem (ie, both wifi and bluetooth)? is your iMac wifi the same speed as it's ethernet port? I haven't checked the specs for you. are you relying on wifi speed to your ISP modem or cat6 speed? older wifi may not be fast enough. did you try cat6 (ethernet direct)?

another issue is you said your ISP clocked it at 500 but Windows 10 gets 200-300. that's inconsistent.

there are still several things to run down before one can comment on whether you even have a "speed" issue or a usage issue

what i mean is: you've only posted 1/2 of the info one needs to know before agreeing the connection is slow or even that your using the right connection

are you using the same cable same router port on both devices?

Thanks. I was wondering what AV Software was. 😁

It's best to avoid unnecessary abbreviations around here, I Think. It wasn't obvious to me.

Well it's good you figured it out.

We've been using the AV or, better yet, A/V abbreviations around here for a long time now.

Yes, I'm aware. Not sure why it was suddenly a big deal. But thanks for pointing it out. 😎

I left out the "/" by accident (typo)

Sorry about that. My post was intended for rccharles, not you.

Not a problem. 🙂
