Ethernet connection hangs

[kalpana]

I'm now getting my wired (i.e. Ethernet) connection hanging on trying to connect. I've tried switching ports (on the router) and using a different cable, but still the same.

ifconfig shows for Ethernet:
enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
ether 50:eb:f6:ef:a4:e6 txqueuelen 1000 (Ethernet)
RX packets 2779 bytes 250524 (250.5 KB)
RX errors 0 dropped 1 overruns 0 frame 0
TX packets 355 bytes 72171 (72.1 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

sudo lshw -C enp2s0 shows nothing

lspci -nn shows for Ethernet: 02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller [10ec:8125] (rev 05)

I found a web page: https://tutorialforlinux.com/2021/05...based-systems/
I followed the instructions and installed realtek-r8125-dkms package OK. On rebooting, I followed the instructed procedure (shown when installing the package) of creating a password and then entering it when requested on the reboot. But still same problem. Any ideas what to do?
PS I've switched Wi-Fi on (though I'd prefer to use Ethernet, as my Wi-Fi is a little flaky due to walls) in order to post this question.
