Slow (capped) 5Ghz wifi on RT-N66u

I could be having the same issues.

I have a Bell (Arris) Home Hub 3000 which is a fibre modem with wifi router. Located in the basement. I have the Bell wifi turned on and it serves parts of the house really well.

I have a RT-N66U on the main floor of the house connected to the Bell router through a Cisco 1GB switch.

I have the RT-N66U set up as follows:
Asus firmware: 3.0.0.4.380_7743 (Which I think is current)
Set up in Access Point Mode
2.4 band set to channel 6 (Bell wifi set up at channel 11 for 2.4) set at 20MHz channel bandwidth
5G band is set to Auto (as is the Bell wifi) . Channel bandwidth is 20/40

My issue is I get intermittent poor performance on the RT-N66U. Slow speeds and dropped connections. Sometimes it is great. My hardwired connections are getting 1GB per second speeds as specified.

After a reboot (from Asus control panel) these were my speed-test results:
My Bell wifi gives me 175MB per sec.
My RT-N66U on 2.4 gave me 60MB per sec
My RT-N66U on 5G gave me 120MB per sec

At times however, these drop way off on the Asus.

Any ideas? Are these speeds reasonable?

Many thanks.

After much more research, it turns out the Home Hub 3000 doesn't support bridge mode. So my wifi gradually eroded, in as little as 30 minutes. I suspect too many conflicts.

More research has led me to having my RT-N66U set-up as a normal router, but in PPPoE mode. I needed the network id/password for the HH3000. The ethernet connection is to the WAN port, not a LAN port. Another subtlety is that the RT-N66U can only be accessed from wifi, not the hardwire connections. After all the setting changes and another couple of reboots and all seems to be up and running well.
