M500 now been online for 24hrs, ping is reasonable, upstream seems on target but downstream not as expected, router in modem mode connected to a Asus AC5300 running Merlin firmware.

Issues getting the hub to run modem mode, seemed to just failed to save the new firmware settings and download a configuration file on restart.

Lost count how many times I had to pin reset the thing, previous M200 package always gave me 216Mbps.

Any suggestions welcome.

What speeds do you get at >>  SamKnows << with a direct connection using a Cat 5E or better ethernet cable between the Hub in Router Mode and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?

Then immediately after …

Can you Login to the Hub Settings and navigate to the Connected Devices page - what is the reported 'connection speed’ for the ethernet cable connected device you used for the speed test ?

[Wolfclaw]

In modem mode, so hub shows no connected devices.

[MikeRobbo]

Is that test going through the Asus ?

[Wolfclaw]

It is, Asus has been rock solid for years with the M200, 5% cpu usage on either core and 300MB free memory, so plenty of spare capacity.

I even tried my 2016 Server which is link aggregated to 2 ports on the Asus, so plenty of bandwidth on that and almost identical results.

[MikeRobbo]

Can you test without the Asus in the LAN please.

[Wolfclaw]

Yep, slightly worse, I know the Hub3 hardware has it's issues .. cough cough Intel PUMA !

Any comment on my power levels etc ?

[Wolfclaw]

More quick tests.

So obviously an issue, not getting 2/5 of speed being paid for, sadly others worse off !
