Poor WiFi Performamce - FortiWiFi 60E with FortiAP 421E

I have a FortiWiFi 60E that I am using (running 6.4.x) and found WiFi performance to be poor.  My WAN connection is capable of 500M and WiFi is barely 100M.  If I use the built in WiFi on the ISP supplied router then this reaches the full 500M easily, so I know it isn't a device limitation.  Have tried various devices as well and all get same results.

 

I had a spare FortiAP 421E so I hooked that up and get the same poor performance.

 

I have tweaked multiple settings and channels but can never get better than about 150M.  I have updated firmware on both 60E and 421E and no improvement.

 

What am i doing wrong and what do I need to focus on to get this performing as it should?  A cheap ISP WiFi Router should not be better than the Fortinet devices :)

 

EDIT: Forgot to add that I would like to keep the 421 attached if possible as I need dual band and I believe the 60E is single band only.

when you are connected wired to the FortiGate you do get that 500M?

 

can you share a screenshot of your used FortiAP Profile?

Yes, cabled in is working much better so this seems to be just a WiFi issue.

 

Attached screenshot for 5GHz as I can't attach more than one for some reason.  But this is the one I am normally using.

you could give 40mhz a chance or add some more channels if you can in your country.

I have tried all sorts of combinations.  What you see there is what got the best speed.  Other options I was barely getting above 1M on some and 10-20M on others.

can you raise a ticket with Fortinet support? they can actually look at your environment and what is detected on the wireless surrounding you.

I think they can only look at the environment if you are in the US. Otherwise they send you to a partner.

This is a fairly old thread, not sure how it was found by you. Fortinet offers site surveys world wide.

Btw... you got response on your other thread.

 

Best regards,
