 |
|
Hello..
i have a gentoo box with 2 NIC's in it, acting as my firewall..
the one covering the internal network, is eth0, and after some time it clocks down from 100 mbps Full Duplex, to 10 mbps Full Duplex..
it's connected directly to the switch, using factory made Cat.5e patch cord. I've tried different cables, but that doesn't matter...
The card is a 3Com 905-TX
The switch, an Allied Telesyn FS708 works perfectly with all other connected equipments..
Anyone have any suggestions as to how i can fix this?
Here's a cutout from mii-diag -w (which makes it keep running, and polls the cards status)

*snip from when i started and up to the interesting part (took a little over 5 days)*
10:22:07 eth0: negotiated 100baseTx-FD, link ok
10:22:08 eth0: negotiated 100baseTx-FD, link ok
10:25:12 eth0: 10 Mbit, full duplex, no link
10:26:22 eth0: 10 Mbit, full duplex, link ok
10:30:00 eth0: 10 Mbit, full duplex, link ok
10:30:01 eth0: 10 Mbit, full duplex, link ok
*snip out of the rest as it's all the same*

Here's lspci output of the nic:

ethtool wont give me anything, but here's what mii-diag tells me:
| Quote: |
Using the default interface 'eth0'.
Basic registers of MII PHY #24: 01ff 784d 0000 0000 01e1 41e1 0004 2001.
The autonegotiated capability is 01e0.
The autonegotiated media type is 100baseTx-FD.
Basic mode control register 0x01ff: Auto-negotiation disabled, with
Speed fixed at 10 mbps, full-duplex.
Internal Collision-Test enabled!
You have link beat, and everything is working OK.
Your link partner advertised 41e1: 100baseTx-FD 100baseTx 10baseT-FD 10baseT.
End of basic transceiver information.
