Title: Very slow AP through put, speed
Post by: guest29664 on September 15, 2021, 02:32:10 am

I currently have the latest version of opnsense on a desktop with an i3 core processor and 8 GB of RAM. None of which according to the control panel is anywhere near maxing. I currently have a Netgear access point attached to my switch which is a Netgear gs724t . everything is 1 GB per second speed including my internet. However the AP (Netgear night hawk Ac1900)only gets about 80 megs per second and my internet seems to bottle off at about 800 Mbps but when I go directly to the modem it's about 980 so I'm losing some bandwidth. I'm using a Jeirdus with Intel 82575 Chipset PCI Express PCI-e Gigabit Dual 2 RJ45 Port Network NIC and everything is attached to a Netgear switch . Any suggestions would be greatly appreciated.

I'm having trouble understanding your setup from the description.

But it seems like you're having two issues.

Issue 1) wireless clients on the AP are not getting good speeds. You'll need to check if they are negotiating on 2.4ghz or 5ghz band. OPNsense is unlikely to have any impact on these clients and their wifi connection to the netgear router. If you plug the netgear router directly in to the modem, do wifi clients have any change in speed?

Issue 2) you only get 800mbps when using OPNsense and a wired connection to your modem. If you plug directly in to the modem, you get closer to the advertised 980mbps speed. You can try the following system tunables and see if these help, you may need a reboot after you save these in the tunables before they take effect.
Disable Flow Control

Code: [Select]

dev.igb.0.fc 0
dev.igb.1.fc 0
Disable EEE (energy efficient ethernet)
