Q:
Networking IP setting and Access Points
Networking
I hope someone can shed light on this dilemma..Here is my problem I have a Linksys BEFSR81 wired router, and a generic (no name) 2.4Ghz. wireless access point router....
and a Linksys EG0801W 8 port switch.

Here is my set up thus far and works and has for years..


Here goes.



Modem Bridged to Router PPPoE

Static IP



Linksys

Working mode: Gateway

PPPoE

LAN IP 192.168.1.1

Subnet Mask:255.255.255.0

Connected to 8 Port Switch where all PC's are connected and is the Wireless Access Point.


DHCP is Disabled, all clients on the Linksys have assigned addresses, I run several servers that require that they stay on the same port.

So on all client machines

IP:192.168.1.XXX

Subnet:255.255.255.0

DNS:XXX.XXX.XXX.XXX

Secondary DNS:XXX.XXX.XXX.XXX

___________________________________


My Access point is connected to the Linksys, from the Uplink port of the Access point.

When Adding my Wireless for my daughter's and my laptop I was able to get on the net by assigning IP's and DNS numbers... I connect to several networks when traveling and have to always go from DHCP Auto and reinstall IP's and DNS when I return home..as does my daughter.

I have tried several times to set the Wireless Access point to Router Mode and DHCP so WE could just start up and go like we do most places, everything auto assigned.

I guess where I am getting confused is the IP, Gateway and Subnet for the Access Point..

I tried this on the wireless access point

Working Mode Router

IP:192.168.2.1

Subnet:255.255.255.0 and 255.255.255.252

DHCP: Enabled
DNS:XXX.XXX.XXX.XXX
Seconday:XXX.XXX.XXX.XXX
__________________________________

When I try to put 192.168.1.1 into gateway field on the wireless it tells me it is a bad IP address..
I have tried everyting I can think of as far as IP's, Gateways, Routing.. any help or suggestions will be appreciated.

So it?s :

Modem====LinksyszBEFSR81====EG0801W====WAP))((Laptop
192.168.1.1 192.168.2.1

Any help on this problem will be appreciated.

You do not mention what you are using for an access point, so I'll just tell you how it could be set up for you.

Since you are using static IP addresses on your network, you need to assign an unused IP address in the 192.168.1.xxx range to the access point. Then, assuming your wired router is using 192.168.1.1 as its IP, that would be the gateway point. This is how you have it set on your wired computers. Also use the same address for DNS as you have for your wired computers.

Then set up the DHCP server. You may use a different subnat for this, or just chose an unused range in your current 192.168.1.xxx network. When you fire up the laptop with DHCP enabled, you should gain the IP fromthe access point and be ready to go.If you are still ahving a problem bring up a DOS prompt and run IPCONFIG /ALL to see what your laptop has picked up for an IP and other settings. If they do not match your settings, check to see where the laptop may be gaining the information from. There may be another wireless network that is giving it an IP, but is not really strong enough to carry much of a signal. Check your wireless settings using the utility provided with the computer to determine the networks available, and select your home access point as the prefeerred access.

Everything stevesz said a right on the money. To troubleshoot this network, start at the WAN link and work out. The Linksys appears to be the connection to your ISP. As such, it should be the router (192.168.1.1), DHCP server and the primary DNS server. The AP and the switch can both be layer two, no IP address is needed in either. As long are setup in VLAN 1, the default VLAN, everything should work fine. If you need to manage them via IP, change their IP addresses to 192.168.1.254 and 253. That way, you know they are not on the .1 address, your router. My home network is like that. I have a Netgear MR814v2 connected to a 24 port switch (I got it free), which only has the default VLAN and an IP address of 192.168.1.254 for management, which I rarely use.You should really only need to administrate the AP for MAC addresses and whatever encryption you are using. Then you don’t need to touch it.
