Once again I have been bested by GNU/Linux. Well, all of a sudden Ethernet broke. I hadn't configured wireless yet (my current networking card uses proprietary drivers; different problem for a different time), so on my Debian installation I don't have internet. I know this isn't a hardware...

Recently, I dual-booted W10 and LM 19.3 Cinnamon (both 64-bit). After dual-booting, ethernet works only on LM, while on W10 it says that it's not connected. I saw a few topics with a similar problem but all of them had no connection on LM, not W10. Feel free to ask for more info and thank you in...

Hello everyone, I am working on a project which requires me to capture packets that don't pass the CRC 32 check. I did some digging and came across ethtool utility, using which we can change ethernet device parameters. To allow the capture of packets, which do not pass the CRC 32 I need to use...

Dear fellow Linuxers, I was a bit uncertain what exactly I want or need, so I thought that the beginner's forum would be most suitable for my question. Please advise if I was mistaken. Setting: I'm currently using my own Ubuntu-machine as my work-computer, and I would prefer a wired internet...

Greetings, I have been having problem with my hardware for quite a while now and have been trying to figure it out on my own just by reading forms and such and I have found a few forms that helped but honestly most of them were complete idiots so I decided to make my own and explain in depth the...

Hi! I'm developing a ofono driver for a new Gemalto modem with 2G/3G/4G. It is a wwan device with 2 ethernet ports. I'm using ofono with connman as the network manager. Everything works fine, except a small detail, the ethernet device is treated exactly as a cable device. That means I can not...

Hello there, I'm not an network admin so my worry is probably dumb to solve, but if it's the case, that would be great :) For my project, I deployed some mini PCs that are all connected to the same router by Wi-fi to be able to synchronize their internal clock. These mini PCs don't have a...
