WAN Bandwidth is 800mbps, but only get half only after MX installed

[Baam]

Hi Everyone, need your help/suggestion/recommendation. 

I got 2x800mbps ISP uplink. Tested via laptop to both ISP Router is able to get 800mbps. However, after installed the MX450 into the network, the speed get by the user is around 300 to 400mbps (tested multiple time a day). Which is quite weird. No traffic shaping is applied. Checked via WAN Health and Dashboard Throughput is also getting 300 to 400mbps.

WAN1 / WAN2 > MX450x2 > 2960 > MR33

Anything that I miss or need to check?

Sounds more likely a wifi limitation, is you mr33 set to 40 or 80mhz channel width?

Did you test from a switchport of the 2960.

[Baam]

tested. same only able to get around 300 to 400mbps

[Baam]

the MR33 is set to 40mhz

How is the uplink configuration in Security & SD-WAN > Configure > SD-WAN & Traffic shaping?

Here is the screenshot of it, am i configure correctly?

A speed test from Insight shows 300Mbps on your MX450 ?

That can't be right.

Here, take a look at this screenshot. i just re-run again the speed test. It is more weird because now is midnight here and no one use the network. but the speed still not satisfying

[alemabrahao]

To be honest, this speed test is not 100% accurate.

Have you tried testing with another tool?

[Baam]

my side still pending to test the speed test using laptop directly connected to MX450. will update later once tested.

do you have any suggestion? i could try them also

[RaphaelL]

That's weird...  When you do the test , do you see the same usage in Appliance Status -> Uplink ->Live data 

The speed test from Insight is reliable , but I would confirm with a PC directly connected to your WAN and run a speedtest from any speed test website.

[Baam]

Thank you for the suggestions. it turns out weird. both speeds does not match. 

is it a bug or got another explanation here?

[RaphaelL]

In that case I think that Insight is not reporting the correct speed results. ( UI Bug ).  I would suggest opening a case !

[Baam]

Thanks for the suggestion, will do right away, and update the case. Thanks!

Already tested from a Laptop connected ISP Router, able to get 800mbps,  here is the screenshot

If you ignore the speed tests in the dashboard and try speedtest.net plugged into a switch port what speeds do you get. 

The WAN speed test does show it's in beta so any results you get from that might not be accurate.

Thank s for the recommendation. Will try again later.
