Tests of SBR reconnection issues with different devices providing dhcp:
it appears that the problem may be specific to the dhcp service
provided by the WGU624 wireless access point. I can't recreate the
problem when using a dhcp service on the SC7 pc or when using a
different wireless access point providing dhcp.
Test details:
Code:
--------------------
My "standard" network: (-- & | == wired; -..- & : == wireless)
Internet --- XYWall P1 firewall (with dhcp server with 1 pool entry)
|
|
WGU624 Wireless access point (with dhcp server with about 20 entries)
| |
: |
| Wired gigabit switch
: |
| |
: SC7 pc (fedora 8, no dhcp server)
|
:
SBR & SBC via 802.11g WPA-PSK
--------------------
Test 1: Disconnect internet & XYWall from network; Disable DHCP
service on Wireless AP (Netgear WGU624); Enable DHCP service on SC7
PC.
Code:
--------------------
SC7 pc's dhcpd config:
[***@slimnas dhcpd]# cat /etc/dhcpd.conf
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
#
ddns-update-style none; # keep it simple for now
ignore client-updates; # here too
DHCPARGS=eth0; # tells it what interface to listen on
subnet 192.168.0.0 netmask 255.255.255.0 {
# --- default gateway
option routers 192.168.0.1; # gateway on your eth1 internal interface
option subnet-mask 255.255.255.0; # subnet mask
option domain-name "soledad.lan"; # domain name given to client
option domain-name-servers 192.168.0.1; # the IP of your ISP's nameservers you're using
option time-offset -25200; # Mountain Standard Time - set to what you have
range 192.168.0.241 192.168.0.253; # the range of IP's your clients will get
default-lease-time 21600; # how long the client's will keep the same IP
max-lease-time 43200;
# we want the nameserver to appear at a fixed address
# host ns {
# next-server resolver2.opendns.com; # change to your ISP's nameservers
# hardware ethernet 00:09:5B:8E:05:67; # hardware MAC
# fixed-address 208.67.220.220; # your ISP's nameserver IP
# }
}
SBR & SBC factory reset. SBC setup to connect to (dhcp-less) WGU624 wireless access point. SBR wireless only (no bridge) setup via SBC.
On the SC7 pc:
[***@slimnas dhcpd]# cat dhcpd.leases
# This lease file was written by isc-dhcp-V3.0.6-Fedora
lease 192.168.0.253 {
starts 2 2008/02/26 15:38:56;
ends 2 2008/02/26 21:38:56;
binding state active;
next binding state free;
hardware ethernet 00:04:20:1a:02:3c;
uid "\001\000\004 \032\002<";
}
lease 192.168.0.252 {
starts 2 2008/02/26 15:39:30;
ends 2 2008/02/26 21:39:30;
binding state active;
next binding state free;
hardware ethernet 00:04:20:16:01:ba;
uid "\001\000\004 \026\001\272";
}
lease 192.168.0.253 {
starts 2 2008/02/26 15:39:36;
ends 2 2008/02/26 21:39:36;
binding state active;
next binding state free;
hardware ethernet 00:04:20:1a:02:3c;
uid "\001\000\004 \032\002<";
}
So...both the SBC & SBR got their IPs from this dhcp server.
(SBC's MAC ends in "3c"; SBR's MAC ends in "ba")
SBR connected to SC7 service and playing music...
Shutting down SC7 pc while SBR is playing:
SBR LED goes WHITE->BLUE; SBC wifi icon goes BLUE; SBC home screen lists: "Settings; Extras; Choose Player"
Restarting SC7 pc: Both SBR & SBC reconnect.
--------------------
Test 1 (DHCP service on SC7 PC) results: Success!! Both SBR & SBC
reconnect automatically!
Test 2: Disable dhcp service on SC7 pc. Reconnect internet & XYWall
firewall; Disable dhcp server on XYWall. Remove wireless AP Netgear
WGU624 and replace with a Netgear FWAG114. Configure FWAG144 with same
wifi network settings as old WGU624 and to provide dhcp service.
Details:
Code:
--------------------
OK, disabling the dhcp service on the SC7 pc and trying a different wireless AP (Netgear FWAG114) with dhcp enabled:
Powering down the SC7 PC: SBR LED goes blue, SBC wifi icon goes BLUE.
Powering up the SC7 PC: SBR LED goes to dim-white, SBR wifi icon stays BLUE.
Power cycling the SBC: wifi icon now white.
Powering down SBC.
Power cycling the SBR: LEDs RED->YELLOW->GREEN->dim white.
Powering up SBC.
Both SBC's and SBR's MACs now show up in the new wireless AP's "attached devices list" and have IPs in the range handed out by the AP's dhcp service.
Powering down SC7 PC (while SBR playing): SBR's LED goes BLUE, SBC's wifi icon goes BLUE.
Wait until music buffer empties.
Powering up SC7 pc..
SBR LED: BLUE->YELLOW?->dim white
SBC (after two "home" presses) Connected.
--------------------
Test 2 (DHCP service on FWAG114 wireless AP) results: SBR & SBC
reconnect after power cycle of SC7 pc.
Moral of the story: failures of SBR & SBC to reconnect may be specific
to certain dhcp servers.
