Hi, I've installed CURRENT on an asus m2n-vm. My network config is giving me problems. Throughput seems low. I'm seeing up/download rates less than 1 Mbyte/sec on my local lan (100Mb). I've tried switching cables/ports in my switch etc. I've enabled device polling (hz=1000) Uploads from the box are slow but "stable". Downloads to the box are both slow and unstable. After a few seconds i see the following lines in my log and all transfers freeze. Doing ifconfig nfe0 down/up brings the interface back to life. nfe0: discard frame w/o leading ethernet header (len 3 pkt len 3) nfe0: discard frame w/o leading ethernet header (len 0 pkt len 0) nfe0: discard frame w/o leading ethernet header (len 8 pkt len 8) nfe0: discard frame w/o leading ethernet header (len 0 pkt len 0) I've tried applying the patch from this conversation: http://www.nabble.com/nfe-busted-on-7.0-BETA4-to14143721.html#a14143721 but i still see the same error. (My dmesg/ifconfig output in the bottom of this mail) Could someone please give me some pointers on how to fix these things? TIA -- Regards Chris My dmesg contains: ata3: [ITHREAD] nfe0: <NVIDIA nForce MCP67 Networking Adapter> port 0xd880-0xd887 mem 0xdfffc000-0xdfffcfff,0xdfffe400-0xdfffe4ff,0 xdfffe000-0xdfffe00f irq 23 at device 10.0 on pci0 miibus0: <MII bus> on nfe0 ukphy0: <Generic IEEE 802.3u media interface> PHY 1 on miibus0 ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT-FDX, auto nfe0: Ethernet address: 00:1d:60:6d:73:ec nfe0: [FILTER] nfe0: [FILTER] nfe0: [FILTER] nfe0: [FILTER] nfe0: [FILTER] nfe0: [FILTER] nfe0: [FILTER] nfe0: [FILTER] pcib2: <ACPI PCI-PCI bridge> at device 11.0 on pci0 and ifconfig -a gives: nfe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=48<VLAN_MTU,POLLING> ether 00:1d:60:6d:73:ec inet 192.168.1.11 netmask 0xffffff00 broadcast 192.168.1.255 media: Ethernet 100baseTX <full-duplex> status: active
