[gentoo-user] Router takes too long to assign IP address

[Mick]

Hi All,

At the title says, I have a laptop that seems to take too long to get an IPv4 
address from my home router.  Other machines on the same LAN that have static 
IP addresses do not seem to suffer this way.

I have tried to configure /etc/conf.d/net to use a specific IP address for the 
particular gateway as explained in:

/usr/share/doc/openrc-0.11.8/net.example.bz2 
============================================
# This is a module that tries to find a gateway IP. If it exists then we use
# that gateways configuration for our own. For the configuration variables
# simply ensure that each octet is zero padded and the dots are removed.
# Below is an example.
[snip...]

# We can also specify a specific MAC address for each gateway if different
# networks have the same gateway.
#gateways_eth0="192.168.0.1,00:11:22:AA:BB:CC 10.0.0.1,33:44:55:DD:EE:FF"
#config_192168000001_001122AABBCC="192.168.0.2/24"
#routes_192168000001_001122AABBCC="default via 192.168.0.1"
#dns_servers_192168000001_001122AABBCC="192.168.0.1"
#config_010000000001_334455DDEEFF="10.0.0.254/8"
#routes_010000000001_334455DDEEFF="default via 10.0.0.1"
#dns_servers_010000000001_334455DDEEFF="10.0.0.1"
============================================

So in my case I have my router at 10.10.10.1 and its MAC address is 
00:11:22:AA:BB:CC.  My /etc/conf.d/net looks like this:
=======================================================
# Define the gateways you want to configure
gateways_enp11s0="10.10.10.1,00:11:22:AA:BB:CC"
# Define the IP and netmask when using gateway 10.0.0.1
config_010010010001_00:11:22:AA:BB:CC="10.10.10.7/24"
# Define the default route for gateway 10.0.0.1
routes_010010010001_00:11:22:AA:BB:CC="default via 10.10.10.1"
# Define the DNS servers to use with gateway 10.0.0.1
dns_servers_010010010001_00:11:22:AA:BB:CC="10.10.10.1"

fallback_enp11s0="dhcp"
dhcpcd_enp11s0="-t 45"
=======================================================

However, the particular router will not provide an IP address soon enough, the 
laptop then sets up an APIPA address and every so many seconds thereafter it 
will try to get an address from the dhcp server.  All this creates an annoying 
delay when I am going online in this LAN.

I am not sure I understand why it goes through the steps shown in the log in 
this particular order and why it says no configuration found (see below):

============================================================


Is there an error with my /etc/conf.d/net, or is this  a buggy router?

PS. Please don't suggest that I wicd or similar - I am trying to understand 
why the above does not work as I think it should.
