Sagemcom wireless router (F@st 3965 CV) @ 5GHZ - 450MBS w/ 50-60MBs downloads via speedtest.net

Brand new TRENDnet TEW-810DR (AC750) @ 5GHZ - 150MB rate w/ 20MBs downloads via speedtest.net

Testing was done using same laptop at same distance away from the routers. Routers were located right next to each other. No other relevant differences.

What am I missing here?

You would have to really dig though the technical specs but I am going to bet the router only has a single antenna on the 5g band. If it had 2 it would claim a rate of 867 for 802.11ac rather than 433. It also means it will be restricted to a maximum speed of 150m on 5g for 802.11n.

Specs indicate 433MBS is possible.

N speed is 300MBS if I recall. It doesn't make sense why the new router has a 2.4GHZ band with 300MBS but the 5GHZ band w/ AC speeds has 150MBS. I am recording the speed using insidder which has 450MBS for my old router but only 150MBS for the new router. I also see lower connectivity rates with the new router vs. the old router. Basically, the new router should be reporting higher rate via insidder and higher connectivity rate than 150MBS.

I MUST be missing something.

They are being very deceptive this is what the specs say.
IEEE 802.11n (2.4 up to GHz 300 Mbps)

Why it does not state the speed for 802.11n on 5g is very questionable.

The only way to know for sure is to find the radio chips sets they use and the number of antenna connections. This information must be filed with the FCC. I already tried a simple search and did not find it. Problem is trendnet appears to be relabeled equipment made by Cameo Communications. Most their stuff has fcc ids from both companies. I would have guessed the fccid for this device would start with S9ZTEW810 based on other models of their equipment but I did not find this and almost everything is years old so they may be using a completely different method.

There should be a FCC id sticker on the equipment. Trendnet starts with S9Z and the other company uses NHP.

Although the documents are a huge pain to read it will very clearly tell you which radios they are using and their abilities as well as how many antenna there are and how much db gain each has.

That would explain the 150MB on the 5G for N but why don't I see A/C being reported by insidder? How is 433 even POSSIBLE?

You would have to have a 802.11ac nic card as well as the latest version of insidder that show 802.11ac networks.

433 is the maximum speed you can get for a single stream 802.11ac using 80mhz channels with the best MCS index of 9. All 802.11ac are multiples of this 433.3 number.

Thanks again for the help. This doens't explain why the other router shows 450MBS (albeit on the N mode; not AC) but I am not sure if that is an AC router.

Because the other router has 3 antenna on the 5g radio. It takes the base speed of 150x3. This feature is called MiMO.

This is why I suspect this new router only has a single antenna on the 5g radio. If it had 2 it could run the 802.11ac at 866 and the 802.11n at 300.

There is no way to really be sure without the technical specifications of the router and it does not appear that the manufacture is being helpful. This is why I always use the FCC databases for this because they must report in a very strict format the the engineers write not the toads from the marketing department. I just can't find this router and the database is to large to manually scan through
