I am seeing SIGNIFIGANTLY BETTER download speeds on the UDM than on an attached HD Flex access point (according to speedtest.net) even though the access points in the two should be similar.

Has anyone seen the same?
Can it be explained??

P.S. my UDM is still a bit hot, and the ventilator does run every now and then.

Hi Tim,  More info needed.
I am an IT Pro by profession with extended experience in networking / wireless signals.
If you can please WhatsApp me 0763751768 as i don’t think i can assist you with a 3000 char limit in this box.
First thing to know is that the software driving the UDM is unreliable, the reason my testing of the product finished quickly.
assuming LAN. you need to ensure your selecting the exact same server when using speed test, the results you get back from speed test, even on the same servers will vary from day to day due to the traffic that populates the CH backbone.
but you can expect results that are approximately near each other. (my advise, select Nexcellence or iWay - i do work in both of those data centres, they are solid speed test services).
next ensure your using the exact same cable on both devices, different category cables will provide differnt results, and even some cables of the same category will provide different results based on how they are manufactured. sortof what Yakovlev has said. although if Yakovlev is experiancing issues which a SFTP cable solves, he has other problems in his environment.
Shielded cables do provide protection from interference but in a home, this should not be necessary.
once you have done these tests. note down the results and try again with a different machine. (eliminates system issues from results) and for all the tests make sure your using a wire.
If you are looking for a product recommendation that will check all the boxes of "awesome" and come at a similar price tag. get a synology rt2600

Answer

I had similar issues before with unshielded ethernet cables.  Try a cables marked as "S/FTP" (Shielded/Foiled Twisted Pair).

Answer

Hi Tim,

I cannot comment on the speed difference between UDM & HD Flex as I don't have a similar setup. I suggest, you can try changing the LAN cable & test it out.

Regarding UDM temperature, mine also runs hot & ventilator spins up when traffic is routed beyond 450 Mbps. Any throughput below that & the ventilator does not kicks in.
