Re: XS512EM ports download speed

SilvexPhoto · ‎2023-03-02

I just purchased a new XS512EM switch from Netgear's Amazon store. Updated firmware to 1.0.2.5, created two VLANs. VLAN1 has port1 for management connected to internal 172.16.200.x LAN and VLAN2 has ports 2-12 for external static public IPs 47.181.202.x. No QoS enabled, no speed limit Everything seems to work fine except I don't get symmetrical speeds on VLAN2. The uplink is a 2G/2G Frontier FiOS using their Optical Network Terminal (ONT) FRX523. If I connect a computer directly to the ONT 10G port I get 2G/2G all day long. If I use my old 2.5G unmanaged switch I get 2G/2G all day long on all ports. I opened a case with Netgear and they have never encountered nothing similar. Did I miss something in the configuration process?. A Frontier tech came onsite and checked the ONT and verified 2G/2G speeds today.

The full picture:

Internet -> FRX523 -> Zyxel MG108 -> XS512EM or XS508M -> PC (using RealTek 8125Rev5 ) I get 2G/2G
Internet -> FRX523 -> XS512EM or XS508M -> PC (using RealTek 8125Rev5 ) 1G/2G
Internet -> FRX523 -> PC (using RealTek 8125Rev5 ) 2G/2G

Are these two Netgear switches incompatible with the FRX523?

I am experiencing the same problem as you are, with similar hardware. Have you resolved it?

I am running
Frontier provided FRX523 ONT (2Gb/s plan)
OPNsense firewall (Xeon E3-1270/16GB ram, 6x10Gbe)
Netgear XS512EM
My PC (2.5Gbe)

I get 2Gb/s down/up all day long connecting directly to the ONT. My firewall only negotiates 1/10gb, so my 2.5 will not provide more than 1Gb directly attached to it, but through the 10-Gigabit/Multi-Gigabit Plus (XS512EM) my nic correctly negotiates 2.5Gb yet I max out at 1Gb/s down, 2Gb/s up going out to the internet

The strange thing is I hit full bandwidth if I hit my firewall using iperf, and/or if I connect to another server internal running OpenSpeedTest either on the same switch, or passing through the Firewall. It's only INTERNET traffic that suffers from reduced download bandwidth, and ONLY when passing through the XS512EM.

Troubleshooting steps I have done include the above connecting directly, swapping cables, ports, local iperf/speed tests, Fresh install of OPNsense and pfSense. Reflashed firmware (both 1.0.2.0 and 1.0.2.5) on the SX512EM, Factory Defaults... I don't know what I haven't tried at this point. The weird thing is it is only limiting my download to the internet. Almost like there's a TTL issue? At this point I don't know what I can do, but it's clear this switch is the common factor.

I returned it and using XS508M. I get symmetrical speeds all day long.
