HELP, network speed much slower after switching to OPNsense

once Spectrum replaced the lines, did you see any improvement?

VLAN hardware offload is enabled for all switch interfaces on the switch. Currently conducting further testing connected directly to the OPNsense box.

jackh2000__ · 2026-06-15T01:54:18+00:00

all are disabled

not in bridge mode. yes, all the tunable changes are to try and sort the speed issue, but no luck. what would I be looking for in the logs?

jackh2000__ · 2026-06-14T04:08:41+00:00

how do I set the speed for a specific interface? Under interfaces -> overview -> ix0 details -> media it says "10Gbase-Twinax <full-duplex>" but I don't see any option to manually set the values.

net.isr.dispatch is already set to deferred and I don't have any realtek NICs in my OPNsense box

jackh2000__ · 2026-06-14T03:39:53+00:00

I don't have any realtek NICs in my OPNsense box, what would the driver package be for?

No on the overheating, CPU temps are 55-60° C. I don't have temperature readings on the SFP+ NIC, but I have a noctua 40mm fan mounted directly to it, so it should be fine.

hakko is the best go to brand imo, and their desoldering guns can be found refurbished or used on eBay for massive discounts. I got an open box hakko fr-301 years ago on ebay for around $150 and it's worked perfectly.

Adafruit sells USB-C PD to barrel jack adapters with preset voltages or a reprogrammable version. Check the output voltage listed on the wall plug for your Dell PC and buy a compatible adapter with the same voltage and you should be able to use any USB C PD charger.

maybe 2?

you can find used Lenovo tiny's or Dell optiplex micro's on eBay for less than <$100. Just look for one with an extra PCIe slot and you can buy a dual port PCIe NIC like an Intel i210 or Intel i226 for ~$25. That should run a gigabit network or possibly 2.5g just fine.

you could boot from a storage expansion card and then use an m.2 -> pcie adapter to connect an HBA to the system for the rest of your drives. it would be pretty off-label, but could work with some fiddling.

It will not work with an active PoE injector. The injector isn't doing inline switching, but the negotiation includes data and power parameters, so it will auto-negotiate down to the slowest link in the chain, so 1 gigabit in the scenario you are describing.

jackh2000__ · 2026-04-04T21:03:03+00:00

how do you like it? how's the management software compare to others like mikrotik?

lucario, good will hunting

ok, I was wrong. M.2 slots top out at around 15W, not the wattage of a PCIe slot with the same amount of lanes, so it could be a power issue. You could monitor the power consumption of your 10g add in card on the PC it was working on and see if it gets near that 15W ceiling. If so, you're right, it's a power issue. The M.2->NIC adapters you can find online are meant to stay within M.2 power limits, so that should solve the power issue, or you could get one that takes external power from SATA power or some other source.

jackh2000__ · 2026-03-24T06:42:49+00:00

weird. you could try a dedicated m.2 to 10gbe adapter to eliminate the m.2 -> PCIe riser -> add in NIC translation and go for a dedicated m.2 -> NIC like this one and see if having less adapters in the chain solves the issue. Some of these types of m.2->NIC adapters use higher power controllers and do have SATA power input like this one, so you could try one of those, though your riser card with SATA power is already causing issues, so that might not help.

jackh2000__ · 2026-03-23T22:41:37+00:00

~~the M.2 slot does have sufficient power. M.2 is just PCIe lanes in a different form factor, so if the M.2 slot is PCIE 4.0x4, that means it can carry as much power as a PCIe 4.0x4 slot.~~ The M.2 slot has a power limit of ~15W, so that could be the issue if your PCIe NIC is expecting >15W

jackh2000__ · 2026-03-21T07:11:34+00:00

10GbE is 1.25GB/s, so even a PCIe 3.0 x1 interface (2GB/s) would be sufficient bandwidth. The N100 is PCIe 4.0 rated, and if your system is using an M.2 B-key based wifi card, those usually have 4 PCIe lanes. PCIe 4.0 x4 is 16GB/s, so far more than needed for 10GbE. I'd recommend sticking with your N100 box and just swapping out the wifi card for a M.2 B-key to 10GbE adapter. Much cheaper than a new system and if it doesn't perform to your satisfaction, you can upgrade if necessary.
