Network setup 'DHCP with manual address' changes to 'Using DHCP'

I have setup my local network with a manual address and have observed that the setting changes without my doing to simply Using DHCP. I can't get the setup to continue using a manually assigned ip address. Even though I've saved the network settings preferences, they revert to 'Using DHCP'. Any ideas? Thanks in advance.

If you "have setup (your) local network with a manual address," does that mean you have disabled DHCP in your router? If so, then you'd want to configure "manually" in your Sys Prefs > Network.
Or did you mean that you have setup a computer on your local network with a manual address using DHCP? (And that your router has DHCP enabled?)
If the router's DHCP is enabled, many routers will allow you to set aside a subset of IP addresses to the DHCP pool, and the remainder are, by definition, reserved for static addressing. Are you assigning the computer requiring a static IPA (but using DHCP defined gateway and subnet) an address falling within the static address range of your local subnet?
If you can't partition the address space between static IP addresses and DHCP-assigned IP addresses when DHCP is enabled, are you assigning a high-numbered IP address to the computer whose Sys Prefs has DHCP with manual address?

Leopard : Network : Unable to use DHCP with manual address.

After installing Leopard on my Macmini (PowerPC 1.42Ghz, 1GB RAM, 80GB HDD), I found my IP address obtains different IP address than Panther and Tiger use. Then I go into System Preferences -> Network -> select Ethernet -> select "Using DHCP with manual address" in the "Configure" combo box, and change the IP address from 192.168.0.8 to 192.168.0.100. Once I hit apply, the network connection never comes back. There is no complaint that another computer is using the 192.168.0.100 IP address. This works if I am using Panther or Tiger on the same computer.
Any help is appreciated.

Setting the DHCP to a number you want to use can be very useful in a busy environment. I usually choose to use numbers that are outside of the range of numbers being controlled by my router (Westell).
Port Forwarding for services like ARD, Azureus, or any server application break when the IP number changes for any reason.
Some routers will not allow numbers outside of a restricted range of numbers that can be set up in the router configuration menu's. In this case, I find out if the router is assigning numbers from the high or low end and make sure I assign numbers at the opposite end of the range.
My Westell router does allow me to use numbers other than the range of 50 numbers it has been told to use for DHCP, but I have also encountered problems when trying this on a wireless connection.

I'm hooked up to the ethernet using DHCP with manual address. It's running (green) but my internet (Safari, messenger, email) doesn't work! Help!

I'm running an iMac with Mountain Lion. Not only do we do accounting work on this computer with AccountEdge, but the computer functions as a server to another computer in a different state.
Anyway, I set a static IP address (Using DHCP with manual address) on it (to allow for a VPN to the computer in the different state) and it is connected (green dot) - meaning that the other computer in the different state can connect to us via that ethernet line - but for some reason Safari, Messanger, and Apple Email won't work.
But if I switch a dynamic IP (DHCP auto), I can use the internet (Safari, messanger, email), but the computer in the different state can't connect to this computer.
How can I fix this so that the computer in the different state can connect to this computer and that the internet (Safari, messanger, and email) can work at the same time?
Much thanks!

No but if they are using a VPN Tunnel for the connection that restricts all internet traffic over the tunnel. Which means you can't use that same computer to broswe the internet or connect to other computers or devices on your LAN.
I'd need to see the actual setup, router and the IP addresses you are using.
Networking and remote networking is fairly easy when you are in front of the systems you are working on. Doing it over the internet on a forum is almost impossible. Tha is why I suggested you get local help, like the person that originally set it up.

DHCP with manual address doesn't work

My ISP has decided that they won't support static addresses for the
DHCP servers anymore. I'd really like to keep static IP addresses, so
I tried using the "DHCP with manual address." Unfortunately, it
doesn't recognize my Router which is serving DHCP. What's busted here?
Is it Tiger or is it my router (old mansesnse MIH-130).
Any help is appreciated.
thanks.

Comcast I believe is a cable connection.
Interesting, I found that if I continue to manually configure the
TCP/IP settings and just point the DNS to the router (192.168.1.1),
all works perfectly. This worked for 10.4.5, 9.2 and Yellowdog Linux as well.
When you say your isp is no longer using static ip addresses this only affecs your WAN ip. Setup your router to receieve internet via DHCP.
Your LAN ip addresss won't change. You can give all your macs static ip addresses if you like. It does not affect your WAN IP.

Just bought a new Airport Extreme BS. After setup my iphone4 won't find the network (not even with manual entries), but my iMac (2009) does. What is wrong?

Just bought a new Airport Extreme BS. After setup my iphone4 won't find the network (not even with manual entries), but my iMac (2009) does. What is wrong?

Well, after another call with Apple support and the engineers, no success. After spending over 20 hours trying to debug this, I give up. Apple was basically fishing for a solution with trial-and-error settings on the iphone. Then they wanted me to plug in software to log my iphone connections to the router, etc, etc., etc., at which point I decided I no longer wanted to participate in their testing process and will simply return the router.
25 hours of my life I'll never get back.
Big bummer, and frustrating for all the obvious reasons.

Network configuration: fully manual vs. DHCP with manual IP

Are there any OS X Server services (e.g. AFP, DHCP, DNS, OD, LDAP) that specifically require a server's network settings to be manually configured, or can they all get my with just manual IP and the rest of the configuration supplied by DHCP?

Oddly enough, I set up a server with DHCP and manual IP and added its IP to a DHCP subnet. But it was also the DHCP server. It did not accept the DHCP-delivered configuration (e.g. it couldn't find the router).
Is it the case that a DHCP server cannot serve itself with network config information?

Cisco Network Setup Assistant with WIndows8

Hi, I'm trying to provisioning on Windows 8(Surface pro)
When the Cisco Network setup Assistant is on, it asks 'network password' while the ssid is wpa2-enterprise.
and I configured as it is on NSP.
Is it a bug ??

Hi,
What version of ise are you on, also what is the windows native supplicant provisioning version? See if the release notes for 1.2 meet your current design.

How to manually configure and then use DHCP

I'm having problems with internet connectivity. If I try to configure in Airport Utility, there are two choices - manual or use DHCP. If I allow AU to renew the DCHP lease, I end up with a bad IP address (one of those 169.... ones). If I configure manually and put in the IP address my service provide gave me, then I can input the address, but without the lease renewal, it won't connect. Put in the address in manual, switch to renew the lease, the bad address shows up.
Obviously, since I'm writing this on-line I have connectivity, via the Ethernet port in the back of my iMac, which has the correct IP address I had to type in and is also using DHCP.
So, what's the difference? Why won't Airport line up things just as the Ethernet network will?

It sounds like your cable/DSL modem is not properly recognizing the AirPort Express Base Station (AX). Most of the time this can be remedied by just performing a complete power recycle when changing network configurations ... like when you switch what is connected to the modem.
Try the following, in order, checking for Internet access after each step, until resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, AX, & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AX, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

Partner address change issue using BAPI_SALESORDER_CHANGE

Hi,
I'm trying to change partner address in an order using the Bapi BAPI_SALESORDER_CHANGE. I have searched the known threads but did not found a solution.
my requrirement is to change partner address without passing address number to 'PARTNERADDRESSES' parameter
This is brief about my requirement.
Our requirement is sales order executin from ECC6 to ECC5 i.e. when a sales order is created in ECC6 it should be created in ECC5 when we save order in ECC6, so in a similar way even changes done in EC6 sales order should be reflectedin ECC5 (whichi includes ATP also) so during this process a user can add additional line items with different ship_to party address, so for newly added line item in ECC6 during VA02 (change process) address number will not be there in ECC5 so i can not pass address number in ECC5 during address change using BAPI_SALESORDER_CHANGE.
since stock is not maintained in ECC6 we are doing above process i.e. sales order execution from ECC6 to ECC5.
so in order to change partner address for newly added line item in ECC6 i will not be having adrees number in ECC5 so can any body plz let me know how to change address of a parter without passing address number to 'PARTNERADDRESSES' parameter of
'BAPI_SALESORDER_CHANGE'.
If any body has faced this and found a solutin for this plz let me know.
Hope you understood my requirement.

give a meaningful title to ur thread, so that, people get u back quickly. Just tip that, try to do ur requirement online, then Observe How the system is behaving....thanq

PowerBook G4 not connecting to new Apple network setup up with Time Capsule

I have a MacMini and Macbook Pro which I have successfully setup to work on a home network with my new 500GB Timecapsule. Only the MacBook Pro wirelessly uses Time Machine with the Time Capsule and the MacMini has its own external back-up.
The Problem is I also have an older PowerBook G4 running 10.2.8 so that my daughter can also run older pre-OS X kids programs and my wife uses the wireless internet on it...until now.
Can you explain why my powerbook will not recognize or login to my new Time capsule network when it was working fine on my old linksys wireless-g? I only want internet access...no back-up.

You could have the time capsule set up for 802.11N. If your powerbook is 802.11b/g then it will not connect. You would have to make sure that the times capsule is set up for b/g as well.

Issues with an LDAP server configured using DHCP instead of static.

Can anyone tell me if there is a known issue using a DHCP address instead of a static IP address to build a 10.4 MAC server that will is a LDAP master?
I have an LDAP master that is running 10.4 that has user account issues. Random users will suddenly not be able to authenticate against the server. I have been told this is because the server was originally built using a DHCP address and then migrated to a static IP. Being a UNIX geek this does not seem to make a lot of sense to me but I am new to MAC..... So?

It absolutely could be the cause of the issue. Open Directory uses Kerberos (among other things) for authentication. Kerberos is VERY VERY VERY particular about DNS... and if your OD master changed the IP address, it could cause these problems. I wouldn't expect that it would ever work, but perhaps some days the IP is the same as it was during initial setup.
Do a 'sudo changeip -checkhostname' from the server and see if it says everything is okay. If not, you definitely have things you need to fix. Frankly, with DHCP on the server you are 100% guaranteed to have problems at some point.

Detect IP address changes when using ServerSocket

We are developing an application which has a ServerSocket, which is started in one machine. That machine is a laptop and it may change the network it is connected to. So the situation is the following:
- The laptop connects to network A and has a IP 192.168.1.1 (for example).
- The ServerSocket is started and it's bound to that IP. It is blocked waiting for new connections, with ServerSocket.accept()
- The laptop changes the network (to network B) and gets a new IP 192.168.100.2
- ServerSocket is still running (blocked in the accept() method), but it is bound to an IP address which is no longer correct.
The problem we have found is how to detect that the IP has changed so that we can "fix" the ServerSocket and bind it to the new IP address.
We have though in one solution: from time to time get the localhost IP address of the laptop and check if it's the same used in ServerSocket. If not, then close the ServerSocket and open a new one.
However, this is not a wonderful solution. Do you know if there is a best solution to solve this?
Thank you very much for help

- The ServerSocket is started and it's bound to that IP.Not unless you specifically program it that way. By default it is bound to all local addresses.
So you don't have a problem.
- ServerSocket is still running (blocked in the accept() method), but it is bound to an IP address which is no longer correct.No, see above.
The problem we have found is how to detect that the IP has changed so that we can "fix" the ServerSocket and bind it to the new IP address.Unnecessary: see above.

IP address changes when using webmail on my ipad.

I can sign in to my webmail however whenever I try to send an email or delete emails etc it disconnects me with a message to say "IP address has changed". It means I cannot use my email account successfully when away from home. Any ideas please?

Check Settings>Messages>Show Subject Field and make sure it's set to "Off".

DHCP vs manual setup for small business peer to peer - which is better?

We have perhaps 10 Macs, a few printers and an imagesetter networked peer to peer, currently using DHCP. Whenever power goes off (once a week sometimes) all of our aliases we use to connect to one another become useless as the router assigns new IP addresses. Would manual address assigning be better, and if so, what's involved? I'm amazed i can't find others in this situation. Thanks.

I have no trouble connecting to an AEBS that is set to hand out DHCP addies by setting a Mac or two or three to "DHCP with Manual Address"... as long as I don't choose an already handed out addy, so with 10 Computers on my AEBS, with addies of 10.0.1.2 to 10.0.1.11, I simply choose 10.0.1.20.
I could go through each computer and Manually set it's IP to the one it got from the AEBS, then reset the AEBS, and everything would be as before, but the IPs would just never change.

Need help with Tiger & XP network setup

Hi all!
Back in the days of OS 7.5, I managed to stick my old faithful Mac onto my family's otherwise all-PC network. All I really needed was internet access - I didn't try to fileshare.
Now that I have Tiger, though, I'm totally lost as to how to set up the network. All the help I can find seems to say "ask your network administrator." The problem is, that's me! I'm hoping someone can help me set up the router and the Tiger computer as well.
Could this be a compatibility issue between OS 10.4 and the router? The router box said "minimum requirements" for Mac are "10.3, 10.2, or 10.1."
I have a D-link DI-624 wireless router. Right now I have a desktop PC wired in with cat-5 cable, and also a laptop PC that connects wirelessly. No problem with those computers. But I cannot get my Mac to see the router, or vice versa.
I've tried setting the router to "allow DHCP server to assign same IP address to specific MAC address." (I found my Mac's Mac address just fine and double-checked it was correct.) After setting that in the router, I hooked up the Mac via cat-5 and edited Network Prefs. First I tried "Configure using DHCP with manual address," and entered the IP address I had told the router to set automatically for the Mac.
(Router address is 192.168.0.1 and I told it to assign 192.168.0.4 to the Mac.)
Safari told me I wasn't connected to the Internet, so using trial and error I changed Network Prefs to "Configure IPv4 using DHCP." No luck there either, even when I tried the "Renew DHCP Lease" button.
Any advice as to whether or not I should be telling the router to auto-assign an IP address to the Mac? I took off that setting completely, and set Network Prefs to "using DHCP," but still couldn't connect to the internet.
Would it be worth re-installing my older copy of OS 10.1 to see if that works with the router, since that is actually listed on the box?
I thank you for any suggestions you have to offer! I really don't know what to try next.

I'm using the Mac wired - it does not have wireless capability, and as it is sitting right next to the router I just want to hook it up with Ethernet cable. The wireless function is just for the PCs I have downstairs.
I am not sure what non-broadcast SSID means, but I think that has to do with the wireless portion of the network, right? I do have a SSID name set up, and WEP encryption so that only the PCs I own can connect to the wireless network, not anyone else's computers. But on the wired PC I have connected directly to the router, I do not have to input any of the security settings. I've even set the router to recognize the MAC addresses of all my computers, including the Mac.
What brand and model of router are you using successfully with Macs & PCs? The store I bought my router from is willing to give me a full refund if I can't get it to work - perhaps I would have better luck with the type of router you're using.
