Slow upload speeds - download is fine (XGS PON)
-
Hello!
I'm running pfSense+ (FW 23.05, Netgate 6100 Hardware) behind a Zyxel AX7501-B0 XGS-PON ONT on a fibre-network.
It's a synchron 10Gbit/s connection while around 8.8 Gbit/s are promissed to achieve.I'm doing speedtests with my Laptop which has a 2.5 GbE connection.
The speedtest does 2.3 Gbit/s download fine.
But the uploads are only at max. 200 Mbit/s.When I connect the original Fibre-Router of my ISP to the pfSense I get synchronous 2.3 Gbit/s in both directions. But as soon as I connect the Zyxel I get only the 200 Mbit/s upload.
I cannot/don't want to use the original router of my ISP because it doesn't support a bridge-mode and I would have a double NAT on my WAN.
In the Netgate 6100 I use a Mikrotik S+RJ10 SFP+ module for getting the WAN-speed that I want to. I know it's not officially supported but as I wrote before: It works fine in combination with the original ISP router.
Traffic shaper has been used in the past but got completely removed from all interfaces.
Status > Interfaces shows 0 In/out errors on the WAN interface.
Thank you in advance for your help and best regards

@dakapo If you spoofcthe MAC address of the ISP router does that help?
-
@SteveITS The MAC is already spoofed. So on the pfSense I spoof the MAC of the ISPs Router. Otherwise it doesn't even let me connect.

Have you looked at top to see if the CPU workload is the bottleneck on upload?

@RobbieTT I checked the 4 CPU-Cores with htop during my last tests and all cores were sleeping.
The current situation is as follows: I did a factory-reset of the Zyxel yesterday in the afternoon. Since then the upload-speeds are fine. I continue observing the situation and will report about any changes again here.

That is encouraging news.
