Bringing up interface on USB NIC



  • Hi - hopefully a quick question:

    I've read the various forum posts on USB NICS and their reliability (or otherwise) as well as the narrow range of devices that are supported.  There's also discussion of the various drivers that work with different devices.

    On the assumption I have a compatible USB NIC, do I have to do anything for that device to show up in the Interfaces tab as a selectable interface (i.e. in the drop down, re0, re1, etc)?  In other words, if it's compatible, will it show up by itself or do I have to initialise it/install a driver manually etc please?

    Thanks.

    I h have few cheap usb to rj 45.  I will test and get back to you. Within 24 hours



  • If is supported just plug in USB wait to be detected and assign/define the interface from menu.



  • Great, thanks for your responses.  So no need even to reboot?  It should immediately appear once plugged in?

    Thank you.



  • yes.
    And once is configured after/if reboot no need to do anything again, interface is already registered/config.



  • Great, thanks.  Looks like my NIC isn't compatible then.  Have ordered a new one off eBay!



  • I have few which doesn't work quite OK, they are detected, I can see them in drop down box, I can set them up with IP's etc, but with some reason they doesn't past any traffic. I can ping them but as LAN interface I cant see any website on the LAN PC's, when I plug different one but also through USB this one works fine (another brand). When I use first one as WAN then pfSense box can access internet, but again LAN not but  at the same time from LAN I can ping WAN IP - strange!

    I think its something to do with drivers - I didn't bother to do bigger investigation, I just used another brand.



  • I only tested one USB to Ethernet with chip set AX 88772b.
    On v2.1.5 it had similar problems like you describe and can't be used.
    On v2.2.3 & v2.2.4 it is working properly, no more problems.



  • The one I've ordered is based on the ASIX AX88179 chipset, which seems to be confirmed working in several posts on here (see e.g. https://forum.pfsense.org/index.php?topic=81634.0)

    Fingers crossed.

    I'm running 2.2.5 so hopefully no issues with USB 3.0 not being recognised at all.



  • I didn't mention - I had this issues on 2.2.2 64bit - I didn't try on newer versions.



  • i tested two of the dirt cheap cards that i bough for 1.5 USD each from local shop.

    both work fine . few seconds after pluging them in pfsense box i was able to see them  . .i assigned them manual ip .enabled dhcp on it and adjusted firewall and nat rules .. connected my pc .. was able to get ip and using iternet through it..

    these are 10 Mbps ones .
    i tried to gauge their throught put using iperf (from pc to pfsense box ) but i cannot make iperf to work on pfbox and i dont have multiple lan ssytems thorugh which i can check.



  • Thanks everyone.

    I bought a Orico UTR-U3:

    Specification:

    • Application: USB3.0 to RJ45 Ethernet LAN Converter
    • Chipset:  ASIX AX88179
    • Interface: USB3.0 Type A Male × ; RJ45 × 1
    • Power Mode: USB Bus-Powered
    • Supports: plug and play & hot swappable
    • CE & RoHS Approval
    • Material: Durable ABS engineering plastics
    • Dimension: 9 x 3 x 2.2 cm
    • Net Weight: 60 grams

    Works fine.  Instantly recognised when I plugged it into pfSense.  No need to reboot or anything.  Working reliably so far.

    does it supports vlans ?
    what is ts throughput ?



  • The USB interface appears in the list of interfaces when attempting to create VLANs, so presumably it does support VLANs.

    I haven't tested throughput, but haven't had any problems.  It handles my 60Mbit fibre broadband ok.



  • I also had some problems at first with a USB NIC. Apple USB Ethernet Adapter for MacBook Air worked for me.
