I have Linksys WRT54G v2. Can I set 5 separate network interaces for each ethernet port (1-4, +wan) on it? If I can, I don't understand, how it would be done. Help me, please.

You may want to take a look at the wiki:
http://wiki.openwrt.org/OpenWrtDocs/Con … dbd3a2f505

You can also use just NVRAM variables to break out your ports into their own vlans. It also works on more devices than robocfg. See:

http://wiki.openwrt.org/OpenWrtDocs/Con … f4e2929172

The variables you need to create/change are:

vlan*ports
vlan*hwname
*_ifname
*_proto
*_ipaddr
*_netmask

After adding your new interface variables you'll want to add entries for them "ifup <ifacename>" to your network startup script and duplicate some lines from the firewall script for the new interfaces (both files in /etc/init.d). This works very well and is consistent with the default interface/vlan configurations.

As I understand, robocfg only work with BCM5325E/536x switch, but Linksys has ADM6996L one, doesn't it?

I already have tried this, but, perhaps, I've done something wrong and anything did not work. As result, I needed to get failsafe mode.
Well, I'll try again, may be I know where is mistake. I am just interesting, what are some minimal steps to catch main principal? Should I change lan_ifname to anything against "br0"? It's seemed to be non-changable.
Should I remove lan_ipaddr and lan_netmask values? Without them it's direct way to failsafe.

So I have 2 questions!

1) Could a person setup a wrt54g with 4 seperate ip addresses and then use a load balancer to connect 4 seperate
DLS/WISP connects to increate the max throughput? 

2) Is there a 'load balancer' package for OpenWRT?

So, I've tried it again, but had not required results.
What I had before:
lan_ifname="br"
lan_ifnames="vlan0"
lan_ipaddr="192.168.1.1"
lan_netmask="255.255.255.0"
lan_proto="static"
vlan0hwname="et0"
vlan0ports="1 2 3 4 5*"
vlan1hwname="et0"
vlan1ports="0 5"

What I've changed:
lan_ifnames="vlan0 vlan1"
vlan0ports="1 2 5*"
vlan1ports="3 4 5*"
vlan2ports="0 5"
vlan2hwname="et0"
vlan1_ifname="vlan1"
vlan1_proto="static"
vlan1_ipaddr="192.168.0.1"
vlan1_netmask="255.255.255.0"

After reboot, I execute
ifup vlan1
and got that ifconfig result:

It is seemed to work, but uplugging the network cable form port 1 and plugging it to port 3 does not make any effect. It is still working with 192.168.1.1 and not working with 192.168.0.1
As I think, It is because of br0 has one common ip address against every vlan have own one. Should I need remove lan_ipaddr value?

Also, know your switch port layout:
