[SOLVED] Wired Connection problem

I have a problem with a wired connection some time. Few days ago works without problem and now start to disconnecting and connecting constantly while wireless works good.

Internet card i I have: Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
Kernel drive: r8169

Does anyone faced the same problem ?

Re: [SOLVED] Wired Connection problem

I've been having this issue on-and-off I *think* since the kernel switched to the r8169 driver, but it's doing it all the time now. I was hoping that https://github.com/torvalds/linux/commi … b6b6cd416c was going to fix it, and it seemed to be better, but now it's incredibly unreliable with the latest kernel.

I was expecting this to be somewhat more widespread, but maybe there are some more nuances to it. I'm using it via a Gigabyte X670 Aorus Elite AX motherboard.

Re: [SOLVED] Wired Connection problem

It seems there was a problem with my internet router. I change it and now wired connection works well.

What did you change in your router settings? i am having the exact same issue on my machine but using a rev0c instead

lspci -nnk | grep -A 3 10ec:8125
0e:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller [10ec:8125] (rev 0c)
        Subsystem: Gigabyte Technology Co., Ltd Device [1458:e000]
        Kernel driver in use: r8169
        Kernel modules: r8169, r8125

I have two machines, one with 05 and one with 0c revs. I have not been able to get the 0c machine working, 05 works perfectly with the kernel drivers. So definitely something to do with the revs.

for anyone here from google :

goto https://www.realtek.com/Download/List?cate_id=584
go down to linux
download the specific driver for your NIC, e.g. mine was 2.5G Ethernet LINUX driver r8125 so I grabbed that file
untar
./autorun.sh
voila! Everything working.

Unfortunately, yes that means you need a way to download the drive somehow, and move it to the machine somehow. But hey it's a one time thing, so I think its doable.
