Some interesting speed test results

[TheLyppardMan]

I think I was asked on one of my recent threads as to why I had replaced my 3-year-old ASUS RT-AX88U with a new RT-AX88U Pro. The reason I got rid of it was because the upload and download speeds dropped dramatically once I moved from BT's Full Fibre 500 service (using the Openreach fibre network) to Zen Internet's Full Fibre 900 service (using the CityFibre network). You can see the results on the speed test history graphs below:

In my opinion, it's a matter of settings, not a new device.

Your tests are meaningless , the speeds available from BT and City Fibre are not the same.

How come; they were both taken using the same test site (ookla), so should be comparable? All the speed tests shown in the graphs were from when I changed to Zen.

I tried different settings, but nothing solved the problem. I'm using the same settings on my new ASUS router and you can clearly see the difference.

What did you do with the old router?

I tried different settings

If you still have both routers, check both speeds over the ethernet cable first.

I sold it on the basis that it was working perfectly well with BT, but not with Zen on CityFibre.

Yeah, it wasn't a router compatibility issue. Either something was configured wrong, it was total coincidence (new router used different wireless channel, or got a different IP from the ISP that routed through a less congested path, etc) or the old router was dying.

The tests I performed were via an ethernet cable, so it still remains a mystery as to why the speed dropped so dramatically when I switched to Zen. Anyway, all is well now.

If it's the ethernet connection results I suspect some setting has disabled HW / NAT acceleration.
