Xfinity gateway won't connect to NIC - Linux Mint


Hi,
I have a new Xfinity gateway that distributes addresses fine over wifi. But when it comes to ethernet, it can't see the NIC on my linux mint PC. According to Mint the NIC is Realtek 8111/8168/8411 PCI Express Gigabit.

The NIC worked just fine with my old FIOS modem/router.

Also, the new Xfinity gateway provides fine Ethernet connection to an ancient MacBook that I had lying around. So the gateway is clearly working in some capacity. Just not for that specific harware. [checked and re-checked cables, etc.]

The gateway is model number Arris TG1682G.

thanks for any suggestions.

Maybe try installing the Realtek driver and see if Mint plays nice with it.

good idea, thank you. I installed the realtek driver and re-booted, but the same result -- the NIC is not recognized.

In poking around my mobo i see an input for "USB LAN." If i buy a ethernet-to-USB converter and connect the ethernet cable to that, will that possibly work (i.e., expose a different NIC to the gateway)? Or will it just be using the same NIC and hardware and driver but a different shape plug?

BTW i'm not sure why the output of the REaltek says "PCI," because it's clearly onboard NIC. I can see it now that i've opened up the machine.

thx for any advice.

I had hoped that installing the Realtek driver would of helped.

Me either:- PCI implies that a PCI crd was installed in the PCI 16 x slot on the mobo.
Glad that your wireless is working.

Check the drivers loading by using the lsmod command.
The driver for the ethernet card may not be loading from the kernel.

Yeah an ethernet to usb converted should work.

I ended up scavenging an ethernet card from an old PC that i had on blocks, and it now works fine, although it's not 10/100.

I am still very curious as to what the MOBO connector does that is labeled "USB_LAN", how is it different from the "USB_1394" connector.

Thanks for your suggestions!

Your Welcome-

The difference between the 2 connectors/adapters appears to be the design.
I think the functionality is basically the same.
Some are 6 Pin Female to USB Male Adapter depending on which one you have.
