I called Netgear and they wanted to sell me some maintenance plan saying that they would FIX the issues "what a scam",.

Indeed Scam most likely - kind of confirmed because of the fake "match the speed" story they told you. The reason? You can not just call Netgear support in most markets. Netgear support does always start on https://my.netgear.com/ or via Contact Us | Support | NETGEAR

IFor one, when I bought the unit, i bought it because it said it supported the speeds. (NETGEAR). Now, they have to change the speed ? Is this true ? am I wrong ? Because, as far as I know, when you update the firmare you update the router to perform to the highest standard.

Leaving any marketing messages and marketing lies all the wireless vendors are using away ...

Let's see what the specs say:

• WiFi Performance : AC3200 (600 + 1300 + 1300 Mbps)
• WiFi Band : Simultaneous Tri-Band WiFi - Tx/Rx 3x3 (2.4GHz) + 3x3 (5GHz) + 3x3 (5GHz)

This means one of the 5 GHz radios can support a PHY link speed (not throughput!) of 1300 Mb/s on a 80 MHz channel, 3x3 MIMO, 256-QAM 5/6. 

And then e.g. the Mac Mini M1 or MacBook M1 says

Wi-Fi 

• 802.11ax Wi-Fi 6 wireless networking
• IEEE 802.11a/b/g/n/ac compatible

This means in performance expectations ... nothing!

Apple is so cheap and does not declare anything but the standard  absolute the worst vendor in this aspect. Most likely, this is a 2x2 system - like the majority of mobile wireless clients in the field.

This 2x2 client can make a max PHY link rate of 866 Mb/s on a 80 MHz channel, and 256-QAM 5/6. Under the line, you might get a max wireless thrugthroughputhput of about 500, probably 550 Mb/s.

An average 802.11ac connection does never make Gigabit.

There are few exceptions (leaving alone the almost non-existing 4x4 802.11ac PCI card interfaces): The Intel AX200 (a 802.11ax wireless client similar, if not the very similar as in your Mac)  makes a link rate of 1733 Mb/s to the Netgear R9000 802.11ac 5 GHz radio - at 160 MHz channel bandwidth (80+80 MHz) and the standard 256-QAM 5/6, resulting in a max and ideal conditions test speed of some ~1125 Mb/s, which is indeed above a wired Gigabit Ethernet link. 

Said that - I'm afraid, you are wrong.

If not, then why would NETGEAR release buggy firmware and reduce or take away the fucntionaliy  of the router ?

---

There are other factors like QoS requiring reconfiguration (based on bandwidth previously available*) resp. needs to be disabled for decent speed for example. Nothing taken away...

* is this probably what the support person tried to explain??

Its' all marketing, it said it could do 1300 on 5hz, I have never seen that possible with my new computer ( m1 mac ), but when you buy other units ie. ASUS, you see that all devices show higher speeds than netgear. Thus, is this a marketing gimmick, ...

---

There is a lot in marketing, but we as users must understand the reality. It can do 1300 - as I've explained above ... 

All vendors use the very same chipsets and wireless radio code - there is nothing A can do better then N than TP than Z than whatever.

So, is there a way to adjust the "FREQUENCIES" -- besides de setting ont he webspage to fix the isseus of the router ?

No idea what you are behind here.

I want to see 1300 supported, and fast speeds, not dropped speeds ...

Otherwise, this is nonsense.
