Link is not ready on USB eth adapter w/ Realtek r8152

I recently bought a USB 3.0 hub with ethernet adapter because my Chromebook doesn't come with an ethernet port.

It is recognized by the kernel, but link is no detected.

Playing with ethtool and disabling WoL or autonegotiation and manually different combinations of speed and duplex yields no results: link is still not detected.

Any advice?

Re: Link is not ready on USB eth adapter w/ Realtek r8152

Hi arslonga

if I tested new realtek kernel driver version 2.04.0 dated 2015/3/11 (http://www.realtek.com.tw/downloads/dow … se#RTL8153), problem with no-link disapeared. I hope that this driver will be part of Linux kernel soon.

My environment: stable Manjaro Linux with kernel 3.19.1, i-Tec USB 3.0 hub with Gigabit Ethernet (https://www.youtube.com/watch?v=hTJ_kZHsdE8)

Hi ivshm,

thanks for the info, unfortunately I couldn't get it running.

I compiled the module from your link and tried to use the adapter but with no luck.

ethtool reported no link and tring to bring up the network profile with netctl resulted in a tainted error from the kernel.

I was having the exact problem as arslonga described it.  I'm running Ubuntu 14.04(Linux 3.16.0-38-generic x86_64) on Zenbook UX305FA using the packaged usb ethernet dongle.

Installing the driver ivshm suggested worked for me.

Thanks!

Same problem with Arch and Linux 4.3 (it worked the first times, but then suddently I got this problem). It works flawlessly with Debian Jessie on a raspberry pi 2 with kernel 4.1.10-v7+.
On Arch I got the very same issue with the asix driver: http://aptosid.com/index.php?name=PNphp … pic&p=6105
The same asix device works flawlessly on the Raspberry Pi.

Had same issue (3.18.24-1-MANJARO).

Found this:

"With USB_BLACKLIST="0bda:8153" in /etc/default/tlp the device works very well..." (https://bugzilla.redhat.com/show_bug.cgi?id=1236679)

Sorted

trg100 - thanks for finding solution. You made my day ...

PS: I used it on 4.1.13-1-MANJARO ... only pitfall was need of reinstalling kernel from package to clear extra driver.

I somehow excluded TLP because I already had USB_BLACKLIST_WWAN=1, but it seems it didn't work. Thanks!

Similar error with 4.12.8-2-ARCH

I've got an XPS 9560 (2017) and bought a usb network dongle to get over the  wi-fi issues.

I really regret moving from my older laptop (sony vaio) with ubuntu. So many issues.
