Hello again, even when changing Lease times etc, each of the PC's on my LAN
are disconnected from ADSL if the relevant PC is left idle for any length of
time. I, and others, think the Router is causing this. It is likely that it
is some setting I have done, so here are the settings as they are, hopefully
something will be glaringly obvious:
I use a D-Link DSL-604T Router, 1 PC hard wired, 3 others wireless.
I use Griffin Broadband who have provided me with the following:
Username: *****
Password: *****
IP Address: *****
Subnet Mask: 255.255.255.255
Authentification Type: CHAP
Encapulation Type: PPPoA
Mux Method: VC Based
Encoding Type: G.DMT
VPI: 0
VCI: 38
Primary DNS: *****
Secondary DNS: *****
Outgoing Mail server: smtp.griffin.com
(I've hidden the DNS's, IP address and Username/Password as it probably
isn't a good idea to publish them.
PC Settings:
TCP/IP settings for "obtain IP Address" & "obtain DNS Server address" on all
PC's are set to automatic.
Router Settings as they are:
"SETUP"
LAN
DHCP config: Start IP 192.168.1.2 End IP 192.168.1.254 Primary DNS
192.168.1.1 Lease Time 999999mins (max I could do)
DHCP Server enabled
DNS CONFIG:
DNS Relay selection - Use Auto Discovered Server Only (I could select User
here)
User Config: Prefered DNS server 139.175.55.224 Alternative DNS server
blank. (I've just changed this to user and entered the Primary & Secondary
DNS server addresses privided by Griffin. I'm still connected so I wonder if
this was to blame?
MANAGEMENT IP:

Product Info & Sytem LOG
"HELP"
Well, while writing this, the only changes I have made are changing the DNS
configuration from Auto to User & entering the Primary & Secondary DNS's
provided by Griffin. I wonder whether this was it?????
Griffin's site also say I'm entitled to 1,4 or 8 static IP addresses.
1, What benefit would I get
2, How would I set up the PC's & Router?
Cheers
Peter
