Re: Unable to obtain a server- assigned IP address Try again later or enter an IP address in Network Setting

In the area where DHCP is enabled there is a section that indicates starting
address, and it will only let you put in the last number, and the maximum
number of users. Make sure that allows for enough users. You might have
filled in 100 in the 192.168.1.100, ( I believe that is the default) and 10
or 20 for the # of users. The DHCP server won't hand out any more addresses
than what is defined.

There is probably a tab or button that will let you look at what addresses
have been handed out and to whom. You should be able to recognize your
laptop and wireless access point in the list.

Your access point should have a number that has the same first 3 groups
(between dots) as the router, and be in the range of the DHCP setup, i.e
192.168.1.100 to 192.168.1.119 (if you have 20 as the number of addresses to
supply). This is if you have your AP setup to use DHCP, which means it gets
it address from the router, not that it supplies addresses. You could set
the AP up by hand to be anything in the 192.168.1.xxx range, EXCEPT for
192.168.1.1 (which is the router) or anything from 192.168.1.100 to
192.168.1.119, because it would conflict with addresses that the router
might give out. The highest # is of course 255 BTW, but only use up to 254.
255 is a special number in a subnet.

The other addresses that must be right on your router are the DNS addresses
your ISP gave you, or the router got using DHCP from the ISP. Note that the
router can be a DHCP client to the ISP network, and also be a DHCP server to
your own internal network.

The AP only has an address in your network so you can talk to it and
configure it. It really acts like a wireless wire with some encryption on
it. Any device looking to attach via wireless must first have compatible
keys with the AP. When it gets by that, it asks for addresses on your
network. The DHCP Server part of your router responds by providing the
device an address out of the pool you set up, a subnet mask (normally
255.255.255.0 in a home network), a gateway (which is normally the router
internal address, 192.168.1.1) and the DNS addresses that the ISP provided.
The DNS are just forwarded on to the device.

When a device wants to talk to something else on your network, it just sends
it to it with it's address 192.168.1.something. router isn't needed. You
also probably have a switch in your router if it has more than one LAN port.
The switch is used here. If a device wants to talk to something on the
internet, it must forward that to the gateway, which in turn forwards that
to the ISP. That's the routing part. This is all IP stuff. If you want to
talk to www.msn.com, you have to know it's IP, so the who is www.msn.com
question, is sent to a Domain Name Server (DNS) via the gateway, so it can
look it up and send the IP back, so your application (like Internet
Explorer) can address to the IP of www.msn.com.

In any case the bottom line is a device must get a valid IP, subnet mask,
gateway and DNS address for it to work. It gets that from the DHCP server
(normally the router in a home network). If it is a wirelessly connected
device, the security must be correct (WEP, WPA) for the device to ever get
the right addresses for it to work. Fast check is to turn of encryption for
a short time on both the AP and the device and see if you get it to work.
Don't mess with other things while you are doing this, because if they did
work with encryption, they won't until you turn it back on on the AP.

Hi Terry! YES.... I am at my Desktop where the router is and the DHCP
is enabled. What should I do?

Terry,

I am so sorry for making this more complicated to understand. I will
try to put the details here:

- I have a LINKSYS router (4 port connection) - I have my cable modem
connected to my LINKSYS. On this router, I have two Desktops connected
to it and the Belkin Access Point connected to it. I currently have 3
wireless laptops (2 - Windows, 1 - MAC) connected to the ACESS point.
All working normal.
- I am able to get into the web-based LINKSYS router Set Up, but it
states nothing about WEB to disable it.
- I also tried (succeeded only once) to get into my web-based Belkin
Set Up page, but it continues to be unsuccessful many, many times.
- The Internet is working with the Router and Access Point.
- It is my PDA that is not working. It was working properly until only
recently. No changes were made to the LINKSYS or the Belkin when it
stopped working.

At present, I have my HP IPAQ 2295 setting as:

General =
Network name: Is set at default
Connects to: Work (but also tried Internet, but it gives me tghe same,
exact results all the time)
Under Configure Network Authentication = Authentication is OPEN
Data Encryption: WEP

Network Key =
Network Key is on and accepted
Key Index: 1

702.1x =
The Use IEEE 802.1x network access control is NOT checked.

Under "Tap an adapter to modify" settings:
For ALL the below, it is set at Default as "Use server-assigned IP
Address"
- Remote-NDIA Host
- PPTP NDISWAN Miniport
- Virtual Ethernet Intermediate Miniport
- NE2000 Compatible Ethernet Driver
- L2TP NDISWAN Miniport
- Bluetooth PAN User Driver
- AsyncMac NDISWAN Miniport
- HP iPAQ Wi-Fi Adapter

My Status at present is:

Connected
Encryption Status: WEP
Access Point: Default numbers
IP Address: 0.0.1.41
more information:
DC+HCO: Enable
IP Address: 0.0.1.41
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1

As for your question here: "On other wireless devices (such as your
laptop, what is the assigned ip address? I will assume it is
192.168.1.xxx ; is that the right assumption?"

No, it gives me the actual IP Address to my Internet Server:
'7x.79.125.xxx" (open group here - I put the "x" there for privacy -
not from you, but others)

I hope this was helpful? Again, THANK YOU for being here for me!

I have decided I don't understand your terminology. Usually you have a
DSL
or Cable modem connected to whatever supplies your internet. This is
extended to your router via a RJ45 cable. The router then hands out
the
ip
addresses to the other devices wishing to talk to the internet (and
each
other). Normally the wireless service is provided by the router. From
your
description, I assume you have a separate wireless access point
physically
connected to the router to provide wireless access.

You said that the pda showed a Gateway of 192.168.1.1 meaning it is
getting
its service via the wireless access point connected to the router.
Therefore
you would reach the router at 192.168.1.1 and the access point at
192.168.1.xxx (an address assigned by the router).

Is this correct so far?
On other wireless devices (such as your laptop, what is the assigned
ip
address? I will assume it is 192.168.1.xxx ; is that the right
assumption?

Terry,

I can get into my router set-up with no problem... I just cannot get
into the Access Point Set Up at ALL???!! OMG this is driving me
insane! I am truly understand about computers and how they work
more
than the average person... BUT this is truly a dead issue for me :(

What is the step for me to get into the Access Point without
shutting
down the Internet??? I know I have to put 192.168.2.254 in the
Address
Bar... I know to change the setting for the Internet Protocal
(TCP/IP)
under Properties... still NADA.......nothing happens and my internet
connection is gone.

I am on my land-desktop trying to do all this.......

When the screen finally changes when trying to access
"192.168.2.254",
"the page cannot be displayed".

ooohhhhh Headache time for me!!! LOL

HI Terry!

Anyone that logs on to my secured, wireless network need only a
code...
a long one for that matter :)
I cannot even get into the router or access point Set Up screen
anymore
without turning off the internet..errrrgggg!!!!
I believe the WEP is normally on..... I am on the wireless
internet
via
my laptop as I write type this...

THANKS for helping me out here.... I just wish it would go back
to
normal :(

Is WEP normally on or off?

Sure sounds like a mix up in the security settings (or maybe
the
MAC
address is blocked). Can you temporarily disable WEP or WPA on
the
router
and try for an address?

I am trying everything right now... However, I am still

I
am
now
getting this reading in my HP Wi-Fi Manager:

Network Information:
DHCP: Enable
IP Address: 0.0.1.41 (This could change to nothing withing
minutes!)
Subnet Mask: 255.255.255.0

When I hit the "IP Renew" button... there is that dang

again!

When this started, no. I made no changes at all. When I

troubleshooting, yes I made changes...but, I put all the

back
to "default" and then back to "my original settings" when
nothing
seem
to work.

Yes, I have 3 laptops working well on my wireless access

at
present. When my family (we are all geeks here LOL) is over
with
their
laptops/PDAs, they can log on with no problem. I also have
two

I uploaded the files from "CAM" to my PDA and found it to be

Have you made any changes to your security settings on
your
Access
Point?
While the AP and PPC radios can connect and show good
signal
strength,
DHCP
requires that the PPC be able to ask for addresses and the
DHCP
server
(usually your AP/router, or Wireless Router) be able to
respond
with
them.
If the security isn't right, then the request can't get
through.
Security
problems could be that it got turned on and wasn't before,
or
that
something
happened to change the Key on either the router or PPC. Do
you
have
WEP or
WPA turned on, and do other devices still work? Laptop,
something?
I
am not
sure if when using DHCP that the addresses are actually
filled
in
on
the
screen on an HP. Anyone confirm that they normally are?

A good tool to see your settings is vXIPConfig, or vXUtil,
both
