Upgraded Internet only with BT router

Go to solution

Hi All

I have had 300 Mbps FTP Internet for a couple of years now. I replaced the BT router with an ASUS Wifi6 router a while back and I get 300 Mbps on both the BT and ASUS router.

I recently upgraded again to 900Mbps and I only see >300Mbps using the BT router. 

Does anyone have any suggestions why the ASUS is still seemingly limited to my old speeds?

Thanks

Paul

When yo say >300 mbs with the BT router do you actually see 900mbs?

How are you measuring the speed, if through WiFi on the ASUS try Ethernet.

What speeds do you get if you run.  Fast.com with ethernet cable direct from ONT to hub wan port

Thanks for the reply

using BT speed checker it complies with the ‘stay fast’ guarantee.

Using Speedtest.net over WiFi I saw 400 Mbps with the BT router

With the same test conditions (WiFi/phone/same distance from router) using the ASUS I saw a cap of 300 Mbps

So it seems like there is some difference inherent to the router I use?

Thanks

There used to be an issue with Asus routers where QoS was switched and speed was being limited. Not sure if that's the case now but worth a check.

And I think we have a winner!

Turned QoS off, and ASUS speed test (built in suddenly showed 700 Mbps and 90 upload.

Speedtest itself showed in the 500’s.

I think that’s it solved!

Thanks all-very helpful

How up to date is the Asus?

I’ve not looked that model up but a lot of the older (and even quite recent) router models had firewall throughputs of around 300-450Mb/s.  This was plenty in the day, of course.  You may need a more up to date model to get firewall throughput of 900Mb/s.

It’s an AX5400 Wifi6 from a couple of years ago. A nice 6E router would be nice as an upgrade!

Much of the time the only way to get a good reading of the speed from the ONT is to set up a connection on a PC, connect this straight to the ONT and then preform the test.  Even then the way the ethernet port is implemented on some PCs it can fall short of what's actually available on the line.

Some Asus routers can give a good representation of the speed using:

Adaptive QOS > Internet speed

but it does depend on the CPU on the router being capable enough to saturate the line (many many of those router CPUs are not)
