I use a RTL8139 ethernet 10/100 adapter (i've tried 2-3 different brands , but this problem remains) to link my ZyXEL 650 Prestige ADSL ROUTER to my PC .
I use linux 2.4.24 and the connection between the router and the NIC is 100MBIT/Full Duplex .
After few times that the connection is started the overruns packets start to rise :
eth0 Link encap:Ethernet HWaddr 00:E0:7D:D5:0C:ED
inet addr:192.168.1.0 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

collisions:0 txqueuelen:1000
RX bytes:3051008 (2.9 Mb) TX bytes:27033528 (25.7 Mb)
Interrupt:17 Base address:0x8f00As you can see I haven't done very much traffic on the net , but those overruns packets comes anyway .
I think that this isn't normal .
Here my datas : mii-tool -v :
