200M : Still maxing out at 150

[JayAy]

Just switched from 150 to 200 today. The modem config is correct to the new speeds, but speed tests are maxing out at 150 - just as if the update was not done. Router (SH2) is in modem mode with a Netgear nighthawk router - so plenty of capacity. Any suggestions about why speed tests are indicating no change?

Have you tried a hub reboot?

[JayAy]

Thanks, yes I've tried that.

I have 8 downstream channels active on the SH2, all numbers look to be within range - even allowing for the hot weather. I think that's enough for 200M isn't it?

Are the speed tests being done wired or wireless? The symptoms you describe imply being done by wireless.

well spotted dude

[JayAy]

Tests are all wired. Gigabit throughout

[Skie]

Have you set any QoS on your router? Might need to raise the maximum speed allowed to account for the new highest possible speed

[General Maximus]

that is what I was just going to say. My MSI motherboard has got a smart app for the NIC and it was automatically set to throttle to 100mbits and enabled. It took me ages to work out what was wrong when I first got my pc and couldn't get more then 100mbits.

Some routers will automatically do speed tests/test your connection to ascertain what you connection speed and you will either have to manually override the result or just disable the feature.

[JayAy]

Thanks.

Don't think it's motherboard related as I get the same ballpark results on different PCs/laptops.

Will have a rummage in the router to see if there's anything limiting throughput.

Dynamic QOS!

Thanks.

Always bet on me.

Glad your sorted
