Slow Wifi speeds, normal LAN speeds. What could I be doing wrong?
-
I just got a new 4 port nic installed and I reset my settings to default. My network for the time being is
Modem - Pfsense WAN port < LAN & LAN2
Nic0
Not being used
Nic1
Modem - WAN
Nic2
LAN - Main Computer
LAN2 - DDWRT AP
-Down
-DownPrior to this I only had two ports on the firewall, WAN and LAN. Now I have about 6, one from the motherboard and 5 from the two NICs. I was thinking that maybe because I was using only one LAN port and the rest from the router, throughput through wifi was being affected.
This is more related to Pfsense since I now maintain the network through it rather than the WRT1900AC. Anything I would need to check on the firewall would be directly tied to the router. The router is basically configured to connect to the firewall and push any DHCP requests to it, everything else has been disabled/unused. I am trying to eliminate everything in between Pfsense and my devices to allow for optimal configurations on my Pfsense router. I know it won't be much, and thats why I lean on this forum to see what would be ideal to run with Pfsense. Then I could focus on Pfsense.
As far as terminology goes, I will have to google and see what you are trying to tell me, but I understand how it's hard to help with little info provided.
No VPN Speedtest Results through AC 20mhz channel width:
Same computer, AC 80mhz width:
I can provide more when I get VPN backup, but for now this is what is normal performance.
This is all done for my personal home network. I am the client ;D.
I wish I had Google Fiber so this could be really awesome, but it's not avaliable where I live.
Also, the AP has 4 antennas on it, and supports simultaneous 2.4ghz, and 5.0ghz. If that helps any.

Nrcropost but did you ever get to the bottom of this? I have the exact same issue. I'm using a router as a WAP with all the router services including DHCP disabled. The WAP bridges onto my Ethernet switch, which the LAN side of pfSense is connected to. I have 2 PC-based gateways, 1 is pfSense and the other is a Linux box running firewalld. Both have 2 Ethernet interfaces - 1 to the LAN and the other functioning as WAN via PPPoE to a VDSL modern.
If I use the pfSense box, wired devices work at full speed but the wireless access is garbage. If I unplug the pfSense box and replace it with my Linux gateway box, both wired and wireless work at full speed.
Wtf!

Can't find another (newer) posts related to my problem and don't want make new post, because this issue is happens with other peoples and my external access point (Xiaomi R3P AC1733 router switched in AP mode) connected to pfSense with same issue.
Have two providers, one connected with PPPoE (100 mbit/100 mbit) another is DHCP client (100 mbit / 100 mbit).
With PPPoE connection there is no problems, all speed is good on all with wireless clients (94.5 mbit/94.5 mbit).
With DHCP there is download throughput problems with all wireless clients, so:
WAN DHCP -> pfSense LAN port -> AP LAN port -> WiFi clients gets not more than 60-70 mbits/94.5 mbits
WAN DHCP -> pfSense LAN port -> client LAN port gets full 94.0 mbits/94.5 mbits
WAN DHCP -> pfSense LAN -> AP LAN port -> client LAN port gets full 94.0 mbits/94.5 mbits
in multi wan load balancing same situation, with LAN connected clients gets 189/189, with WiFi clients gets only <150/189.pfSense Version 2.4.4-RELEASE-p3 (amd64).
Seems that is problems in pfSense with WAN DHCP client mode and external WiFi AP, what i can do for make it works better?

Run a packet capture on that traffic and see what the difference is or if there are errors shown.
Really the only thing I could imagine is some sort of packet size problem.

I have run capture on both connections traffic (WAN and LAN interfaces), no errors or failures... -
Same packet sizes? Not loads of fragments maybe?

@stephenw10
My pfSense is working under Hyper-V of Windows Server 2019, i have passthrough all 6 intel EM based drivers NICs to guest pfSense machine.
For testing, i have make another guest machine with OpenWrt and passthrough dedicated WLAN card to it, than connect both via Hyper-V virtual switch and make tests, seems that speeds is good (even in load balancing i can achieve 185/189 mbits) and no issues at all. So, i can't understand, why it can't work in full performance with another router in WiFi AP mode connected by LAN? -
The only significant difference there is the connection type, PPPoE, usually has a smaller MTU to allow for the PPP overhead. So perhaps traffic coming from wireless is hitting that somehow. Hence:

I don't understand question, what and how check to answer?

In the packet capture do you see fragmented packets?
Do you see larger packets on the wireless intrerface that from wired clients?
Or just any difference there?
