RT AC 68U

You result are in the 2.4 GHz ?

yes, on both Routers

Try to configure the AC68U in 2.4 GHz 802.11n mode only instead of mixed mode,make sure AES encryption is selected. Also test it with the 5GHz speed and post your result.

The Bell modem/router is not in bridge mode, the 68u's internet port is connected to a lan port on the modem, the 68u's Internet connection is set up for DHCP, you're using 5 Ghz band to test, and no VPN is running on your phone. Correct?

Correct, except I am testing on 2.5 GHz.

Test on 5 GHz.

What app or site are you using to test speed?

Tried both options as you suggested and it still the same. But on 5Ghz I get over 200 mbps. But I dont get good coverage on 5 Ghz on my upper floor

I get over 200 mbps on 5 Ghz but then the covergae sucks and I dont get a good signal on upper floor. The app I am using is "open Signal" it is a very good app and also you can find the wiress towers in your area with this app.
I am sure there is nothing wrong with this app as I use the same app when test speed on Bell 3000 hub and it gives me good results.

I just thought of something, may one of your router has a 40 MHz channel on 2.4 GHz and the other one a single 20 MHz channel ?

My 2.4 is on 20 Mhz and 5 is on 20/40/80.

Both routers used 20 MHz on 2.4 ? It may be called channel bonding or channel + in some routers.

Close to your Asus router you should be able to have at least 100MBs on a 20MHz channel and 200MBs. on 40MHz ( in the 2.4GHz band)

If not, make sure you have the latest firmware and post some screenshot of your config. Depending on the facts, you could need to replace it.

This sounds pretty normal. 5GHz doesn't penetrate through walls nearly as well as 2.4GHz. If you've got a few walls between your upper floor devices and the router, you will likely get better performance using 2.4GHz.

OTOH, standing beside the router, or even one floor above (if you're reasonably close) you'll get better speeds using 5GHz. In the same room as my AC68U I get ~500/300. Using 2.4GHz I get 74/100. I have the gigabit Fibe package BTW (which gives a solid 940/940 when wired via ethernet to a PC with a good NIC), and I'm using the Speedtest.net app on a Google Pixel 3a.

I actually have three routers on hand and did a bit of quick testing. My Bell router (not the HH3000 but an older model that connects to a discrete fibre modem) gives very similar performance to the Asus, as does my TPLink Archer C7 v2. There were minor differences, but all three routers performed within 20-30 mbit of each other while in the same room using 5GHz.

OP, if you want I could do some more tests and put together a table showing the relative performance of these three routers using both the 2.4GHz and 5GHz bands, along with their performance in the same room and at different points on the same floor and one floor above. I'm confident everything is set up correctly -- the Bell device is doing the routing, while both the AC68U and the Archer C7 are set up as access points. This might give you a sense of the performance you should expect.

My theory is that despite all the marketing that manufacturers throw at us (showing highly theoretical speeds using multiple antennas), most routers/APs will perform quite similarly to each other when connected to a single, typical device like a smartphone or laptop. From what I've gathered in my own research, there is a hard upper limit to how well a router can perform in this scenario since radio power output is restricted by law.

Anyways, I've got lots of time on my hands thanks to Coronavirus-related unemployment. Just let me know if anyone is interested in seeing the results of such a test written up!

I put together an outline of the test I'm planning to perform. Hopefully someone will find it useful.
