Carlos,
the 10mbps would explain everything and I've never seen that speed in the
camera. And before trying to fix problem with reflashing (making sure to
overwrite the network configuration) I would like to try to find out - what
is wrong now. The mii-diag output in the camera I have shows:
[root at Lens_Adjust /var/log]797# mii-diag
Using the default interface 'eth0'.
Basic registers of MII PHY #0: 3100 786d 000e 7237 01e1 cde1 0009 0000.
The autonegotiated capability is 01e0.
The autonegotiated media type is 100baseTx-FD.
Basic mode control register 0x3100: Auto-negotiation enabled.
You have link beat, and everything is working OK.
Your link partner advertised cde1: Flow-control 100baseTx-FD 100baseTx
10baseT-FD 10baseT, w/ 802.3X flow control.
End of basic transceiver information.
There is also a file /var/log/mii-diag.log , here is what it has on my
camera:
[root at Lens_Adjust /var/log]797# cat /var/log/mii-diag.log
mii-diag.c:v2.11 3/21/2005 Donald Becker (becker at scyld.com)

Using the new SIOCGMIIPHY value on PHY 0 (BMCR 0x0000).
The autonegotiated capability is 01e0.
The autonegotiated media type is 100baseTx-FD.
Basic mode control register 0x3100: Auto-negotiation enabled.
You have link beat, and everything is working OK.
This transceiver is capable of 100baseTx-FD 100baseTx 10baseT-FD
10baseT.
Able to perform Auto-negotiation, negotiation complete.
Your link partner advertised cde1: Flow-control 100baseTx-FD 100baseTx

No specific information is known about this transceiver type.
I'm advertising 01e1: 100baseTx-FD 100baseTx 10baseT-FD 10baseT
Advertising no additional info pages.
IEEE 802.3 CSMA/CD protocol.
Link partner capability is cde1: Flow-control 100baseTx-FD 100baseTx
10baseT-FD 10baseT.
Negotiation completed.
Monitoring the MII transceiver status.
00:00:16.139 Baseline value of MII BMSR (basic mode status register) is
786d.
Value of MII BMSR (basic mode status register) is 786d.
I would also try to change MDI/MDIX settings (provided your computer/switch
is "auto mdi/mdix"). Edit the /etc/conf.d/net.eth0 :
# (C) Copyright 2005-2007, Axis Communications AB, LUND, SWEDEN
# This file is released under the GPL v2.
# Uncomment the following line to override the generic hardware address
# (usually the serial number) for this interface only.
# MAC=00:0E:64:00:00:00
# Valid boot protocols are "dhcp" and "none" (anything other than "dhcp"
works).
BOOTPROTO=none
DHCP_CLIENT="/sbin/udhcpc -i eth0 -H $(hostname)"
# Valid media types are "auto", "10baseT-HD", "10baseT-FD", "100baseTX-HD",
# "100baseTX-FD" and "" (nothing).
MEDIA=auto
AUTONEG=normal
# If you are using DHCP the following variables will not be used.
IP=192.168.0.236
NETMASK=255.255.255.0
BROADCAST=192.168.0.255
GATEWAY=192.168.0.15
# MDI/MDIX configuration; nothing or any - auto by default; "mdix" - for
MDIX (cross); "mdi" - for MDI (normal)
MDI_MODE=
-------------------------------
You may try to change the last line to
MDI_MODE=mdi
or
MDI_MODE=mdix
and reboot the camera :
reboot -f
And copy /var/log/mii-diag.log
Just make sure you can edit the file with vi:
vi /etc/conf.d/net.eth0
because if you set some wrong with the network, you'll only be able to
communicate with it over the serial console (or have to use low-level
reflash).
