Network problem in F21 with my Amilo Siemens laptop

[Joachim Backes]

Hi F21 testers,

after installing F21, I have network problems with my (old) Amilo
Siemens laptop:

(02:0a.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 10)

Seeing a lot of RX errors:

ifconfig
em1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.100.106  netmask 255.255.255.0  broadcast
192.168.100.255
        inet6 fe80::203:dff:fe1d:c58d  prefixlen 64  scopeid 0x20<link>
        ether 00:03:0d:1d:c5:8d  txqueuelen 1000  (Ethernet)
        RX packets 13985  bytes 16907527 (16.1 MiB)

        RX errors 231  dropped 299  overruns 231  frame 0

        TX packets 11105  bytes 2238807 (2.1 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

No problems with the builtin wifi:

02:0d.0 Network controller: Intel Corporation PRO/Wireless 2200BG
[Calexico2] Network Connection (rev 05)

Additionally, no problems with knoppix on the ethernet interface em1.

Anybody has a good advice how to find out the reason for this behaviour?

Kind regards

Joachim Backes
