DHCP and Static IPs?

I'm running a Linksys BEFSR41v4, and have run in to a few problems and was
wondering if my setup was wrong or if I have a bad router. I've setup the
router for DHCP (Range 192.168.1.100 - 192.168.1.255) this seems to work
fine with my laptop and other devices that can use the DHCP. BUT if I set my
laptop to a static IP of 192.168.1.200 I can no longer connect to the inter
net. I've been trying to connect a few devices to this router that have
static IP's, I'm able to ping the devices but am not able to connect to
them. IDEAS...

It was suggested that if my DHCP range is 192.168.1.100 - 192.168.1.255 that
the static IP addresses need to be low than 192.168.1.100 is this true? I
assumed that all devices needed to be within the DHCP range so that all
computers and devices could see themselves. Thoughts?

HotRdd:

Static IP addresses MUST be outside the range of the DHCP pool, in
your case 192.168.1.100 - 192.168.1.200. If you think a moment this
makes perfect sense. The DHCP server has no idea that a STATIC IP
address has been assigned to some PC on the LAN untill it tries to
hand out the same address and a conflick arrises.

Assign anything requiring a static IP an address in the range
192.168.1.1 - 192.168.1.99 and all should be well.

I know for a fact that we only have about ten PC's using DHCP so they would
cover 100-110, if the static IP address is around 200 and not used by the
DHCP server should it still work or must it be outside the DHCP range? Does
the Static address have to be lower or can it also be higher than the DHCP
range...

HotRdd:

When DHCP is configured typically there is a place to define the
"pool" or range of IP addresses that will be made available via DHCP.
Aything *outside* of that range (But still in the same subnet as
defined by the "Netmask" value) can be used as a static IP address.

Most systems default to a Netmask of 255.255.255.0 Meaning that you
will have all 255 possible addresses available on that segment of the
LAN.

Good Luck

John

What do you have for a Gateway and DNS address. Usually you can use the
routers internal I.P address as the Gateway and DNS. Put your ISP's DNS as
2nd DNS address.

Thanks,
Bruce
