Re: [SOLVED] Random ethernet disconnections

One thing in this thread I have not noted.  Are Windows and Arch bringing the NIC up in the same configuration?  For example Arch connecting at 100Mb/s while Windows is opting for 10Mb/s?  Is one or the other choosing half duplex?

Re: [SOLVED] Random ethernet disconnections

This is my motherboard, comes with an integrated IO shield: https://www.asus.com/motherboards-compo … m-plus-ii/
The cable snaps in, but unlike my laptop, it has some wiggle/pull room, although wiggling it or pulling it doesn't seem to make it disconnect.

Last time I checked, it seems that Win was using 100Mbps, but idk about the duplex state.

Re: [SOLVED] Random ethernet disconnections

New network card arrived. Same Realtek chip:

❯ lspci | grep -E -i 'network|ethernet'
04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller (rev 26)
08:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller (rev 07)

No disconnects or negotiation fails anymore, even after uninstalling r8168. Been using it for an hour, runs like a charm. Marking as resolved. Big thanks to seth for sticking with me.

Re: [SOLVED] Random ethernet disconnections

We have two computers in the house with the same Rev 26 chip and have been having issues for months. Random disconnects, often within 30 seconds of logging in. We restart the switch, it comes back, we restart the router, the computers come back, replaced the switch, same issue, replaced the Ethernet cables, same issue. Other wired computers on the same subnet/vlan are not having the problem.  For the past week or so, it has been stable on both. I am wondering if an update corrected something. Regardless, I am close to getting some Intel PCI cards if it starts happening again.
