Router connected to cable modem by Ethernet port cannot get IP address from DHCP.

I have an ethernet cable on Fa0/0 connecting my 1841 router to my cable modem. The issue is that the router cannot obtain an IP address via DHCP when I have the "ACL-OUTSIDE-IN" ACL applied inbound on the Fa0/0 interface. I tried to allow all BOOTP and BOOTPS traffic in my ACL, but still no luck. I really don't want to run the router without a simple ACL firewall and connect it to the internet. When I take off the ACL off of Fa0/0, the router is able to get an IP address via DHCP.

Networking issue with new Macbook - cannot get IP address from DHCP router

Hello all, I've seen this problem posted a few times and been having the same problem with my new aluminum MacBook. Here's the story:
When connecting to my network at home, I get the message "Airport has a self-assigned IP and may not be able to connect to the internet." I've been able to connect a few times, but anytime it sleeps or I shut down I have the same problem. When I'm out and about, it has no problem connecting to other networks.
On the network in which I cannot connect, there are 2 other macs and two PCs that do NOT have any problem connecting. Macs are all running 10.5.5.
Router in a 2Wire and uses DHCP. ISP is AT&T.
I've tried rebooting the router, manually assigned an IP address, restarting, updating software. Nothing seems to work.
Does anyone have any other suggestions? This is kinda making me crazy.

I've also tried:
1) Creating a new location in network prefs.
2) Zapping PRAM
3) rebooting router many time.
4) putting a $ in front of the hex password
5) deleting all of the plists that I've seen recommended.
6) Starting in safe mode
7) Renewing IP
8) Shutting off firewall

Hi i just bought a wireless router and i cannot get it to...

hi
i just bought a wireless router and i cannot get it to work. it is a wrt54g v6. the power light keeps flashing. I tried talking with linksys to get it fixed, but nothing is working. it says to disconnect from the modem and update my firmware, but i cant get the IP address to come up on the address bar. can someone please help me out.
thank you
angela

If you have just bought the router and it has a flashing power light return the router. It is not worth trying to revive a broken router in that case. Return the router and get a properly working one. I would not want to start with a broker router even if you may be able to revive it. You'll never know what caused the problem and whether you will have more issues later.

Unable to get IP address from DHCP

hi all,
I have a AP1131 which cannot get IP from DHCP server. I have tried to configure static IP address and controller IP by lwapp command and the AP can successfully joined the controller. However, after I changed it to DHCP in WLC, it cannot get IP address and all lwapp config is gone. It cannot join the controller anymore only after I reset it and configure a static IP for it. The following error message appears after I changed it to DHCP in the WLC:
*Mar 7 08:44:36.511: RESETTING THE STATIC IP ADDRESS: LWAPP goes back to discovery
%WIDS-6-DISABLED: IDS Signature is removed and disabled.

Any expert has some idea on it?
Thanks.

Is that AP on the same subnet as the other AP's? The thing is, when you configure the AP with static information, you say the AP is able to join the WLC. This means that there is no issue with the AP. Now when you set the AP to use DHCP and not static, the AP does not obtain a DHCP address? Is that correct? If you have more than one AP on the same switch and on the same vlan, and only one has an issue, then maybe reset that AP to default and see if that fixes it. I'm also assuming that the vlan is being forwarded and you have enough dhcp address in the scope.

Trouble getting IP address from DHCP-enabled router

I've recently set up a LinkSys WRT54G wired/wireless router on a home network that has a wired Windows XP machine and a wireless PowerBook with AirPort.
The WRT54G assigns network addresses using DHCP. The PowerBook is able to find the wireless network established by the WRT54G, but doesn't get an IP address from it.
The router seems to be behaving correctly, so I'm guessing there's a problem in the PowerBook setup somewhere. Any ideas?

Double-check your AirPort's settings:
System Preferences > Network > Show > Network Port Configurations
- Verify that an AirPort option exists. If it does not, click "New" to create one. (Note: If you are unable to create an AirPort configuration, the AirPort card in your computer either doesn't exist or it is not recognized.)
- Verify that AirPort is "On" (checked)
- Verify that AirPort is at the top of the list. If it isn't, you can drag it to the top.
Systems Preferences > Network > Show > AirPort
AirPort tab
- By default, join: Automatic
TCP/IP tab
- Configure IPv4: Using DHCP
- Configure IPv6: Automatically or Off
Proxies tab
- Configure Proxies: Manually
- Select a proxy server to configure: <All proxies should be unchecked unless you specifically require a proxy for Internet access.>
- Exclude simple hostnames (unchecked)
- Bypass proxy settings for these Hosts & Domains: <leave blank>
- Use Passive FTP Mode (PASV) (checked)

Unable to get ip address from DHCP server for Aironet 1130AG Access Point

I have a network in which DHCP server is enabled. I have read the installation guide also there it is mentioned that 1130G Access point will not have any staic ip assigned to it.So it will automatically get the ip from the DHCP server from the network. I have connected that from the network but it is unable to get the ip address from the same. The same thing i have configured in the netgear it is coming fine. I have seen the sonic wall and used the IPSU tool also from checking the ip address from Mac Address but i am not able to get the same. Please provide me some tips to check where i am wrong in configuration because the first web page also not coming because of the ip address.

narendra,
I would suggest that the AP be connected to a laptop or desktop pc that would run a local dhcp server with a small scope setup...plenty of free ones on the web(this pc would obviously not be connected to your currnet network). This way you can watch the dhcp server hand the AP it's address (this can take a few minutes). Once you have the address use it to access the GUI and give the AP a static address (I find it good pratice to give all my autonomous AP's static addresses for ease of troubleshooting)...Hope that helps.

IPad wont get IP address from DHCP Server

I have an enterprise WPA2 PEAP MSCHAPv2 wireless network. It allows access via 802.1x authentication using Radius (MS IAS Server) with certificates. I can join the network, enter credentials (that I can see work) and get the certificate. The problem is that I don't get an IP address. I get a 169. APIPA address. I tried to use a static IP address and that doesn't work either. I have connected various laptops, iPhones even a Dell Streak to this wireless network without issue. My iPad won't get an IP at all. There are plenty of addresses in the pool.
The setup is a 3COM WX3008 wireless LAN controller and 9552 access points.
Any ideas? I went through the articles on wireless settings and none of them help at all. I guess my next step is to wipe the iPad.
Like I said... EVERYTHING else works, every other device we try is surfing just not the iPad.

I see what you are trying to say but in this case its just not true. There is a problem with the iPad. Moving away from the most secure wireless technology or changing my "router" isn't a reasonable solution. We are using a current production model enterprise wireless LAN controller with lightweight access points. Its running its latest code. Its not the Free After Rebate model from the local B&M.
Again, when everything BUT the iPad works (iPod/iPhone/laptops of varying OS & vendor are all good) its not the routers fault. While downgrading my network may work it is not a reasonable solution to a problem with only the iPad.
Of course I don't like hearing it. I am here to hopefully find someone else with the same issue or get some tips that lead to a solution so the next google searcher will land on a solution.

Unable to get IP address from DHCP since upgrading

Hi all,
I upgraded my machine to Mountain Lion last night. Ever since then I have been unable to get any IP information using DHCP. Each time I hit Renew Lease within the Network control panel I just get back a self assigned IP address. If I look in the system logs I see the following generated each time my machine tries to look for the DHCP server:
Jul 26 01:32:27 Lightning.local configd[22]: bootp_session: bind port 68 failed, No route to host
Jul 26 01:32:27 Lightning.local configd[22]: bootp_client_open_socket: S_get_bootp_socket() failed, No route to host
Jul 26 01:32:27 Lightning.local configd[22]: bootp_client_bind_socket_to_if(en1, 6): session socket isn't open
Jul 26 01:32:27 Lightning.local configd[22]: bootp_session_transmit: neither bpf nor socket send available
Jul 26 01:32:27 Lightning.local configd[22]: bootp_client_bind_socket_to_if(en1, 0): session socket isn't open
Jul 26 01:32:28 Lightning.local configd[22]: bootp_session_delayed_close(): socket is already closed
I've tried rebooting, clearing the PRAM, deleting Prefs, etc, but nothing seems to have worked.
Anyone any ideas what is going on or what else to try? It used to work perfectly before I upgraded.
Thanks

I am also having this problem since I upgraded to Mountain Lion. I did an upgrade from Lion, not a clean install. I had done a clean install of Lion though. In my case, the network connection is working most of the time, but it is droping one a day. Deactivating the Ethernet and the Wi-Fi adapters and reactivating them does not help.
Here is my what I am getting in the console when I have lost internet connection and I try to renew the DHCP lease:

I am a fitst time user of the new airport extreme time capsule 2TB. I have a mac book pro and an imac. I installed the router today and got my computers online wirelessly. BUT I cannot get my previous wireless printers to connect with the router.

I am a first time user of the new airport extreme time capsule 2TB. I use a macbook pro and imac. I installed the router today and got on wirelessly. BUT I cannot get my 2 printers that were previously wireless to find the router signal. The worked fine on my current set up OS Mounitain Lion 10.8.4. Apple tells me it is the printer mfr issue and printer companies tell me it is apple issue. Any help appreciated.

Arguably, they're both right.
Changing your router changes everything, so your best course of action is to research the respective printer's documentation and determine how to reset them to factory default condition. Then, add them again using System Preferences > Print & Scan.
For that, I recommend you first "reset the printing system" according to these instructions: Mac OS X: How to reset the printing system. Its instructions for Lion are identical to those for Mountain Lion.
As the article states, it will remove all your existing printers, leaving the Mac's printing system in a similar "factory default" condition ready for you to create a new print queue for each printer, which you should probably do.
Apple's printing support documents contain a great deal of redundancy, but this one may be a good place to start: OS X Mountain Lion: Set up a printer to print wirelessly

Have situation on a unprotected wireless when accessing I cannot get a router address. I'm on system 10.6.8 on MacBook Pro summer 2009. Any thoughts on how to determine what's up?

You have basically verified that the issue is NOT with your MBP, but with this particular Wi-Fi network. Even though it may be unsecured, the provider may have elected to configure it for MAC filtering. In this case I am referring to the MAC (Media Access Control) address and not your Mac laptop itself. If this has been enabled, your Mac would only be able to connect if the Mac's MAC address was added to that filter.

Cannot get an IP from the Router - Limited or No Connection

Help!
Hello,
I have a Linksys Wireless G router and 2 XP computers that were
working fine.
I am using it wired - no wireless being used.
Now one get an error that is there is low network connectivity and
cannot connect to anything.
The other computer - fine. So X - no connection, Y - connected
I tried swapping cables - same situation (different ends, new cable,
the one from Y) - X no network, Y is fine. Switched router ports -
same situation X-no, Y - yes
Plugged in modem directly into X - works FINE.
I did check the security center in the control panels - in both cases
the fire wall is on, but the windows firewall is off. I cannot
disable the firewall from X - it must be the router firewall (I tried
removing any filtering from the router - same issue). Again, Y works
fine.
Only when going through the router does this cause a problem.
Direct connection is fine.
To top it off, when computer X is booted up in safe mode and going
through the router - it is fine. An IP address is taken. In regular
mode the computer boots up and shows an IP address of 169.254.x.x. I
tried power cycling the mode, router, both, reboots - same issue
169.254.x.x. I tried hard coding the IP address to the one found on
the router and in the range of the router - no dice.
Why can't I get an IP address from DHCP?
Computer X does not Norton Antivirus on it - I disabled it in regular
mode - same problem. I do not want to uninstall it.
I read about a Service Pack 2 problem with XP - but the problem does
not appear in Safe Mode with Networking and I did try the fixes my MS
about it - to no avail. The underlying issue is that computer X
cannot get an IP address from the router.
Computer X work when:
- there is a direct connection from the modem (DSL) to the computer
in regular mode
- booted up in Safe Mode and attached to the router - can ping it,
surf the net
Computer Y is fine with the Router.
Suggestions on how to proceed?
Help!
Thanks!

Hi,
I tried it - same problem.
Did the netsh command and reboot.
Did the mtu change.
Same problem.
Reset the router and tried all over - same situation.
The DHCP client list shows 2 ip addresses - one for the computer that does not work and one for the one that does not.
Same IP addrsses as before.
192.168.1.100 - does not work - but the MAC address hows, and so does the computer name.
192.168.1.101 - does work.
Again, the computer works in safe mode (and connected to the router) and with a direct connection. The issue has to be with the router.
Is there any way I can for the computers to swap router IPs?
Thanks,
Tmuld

Guest users not getting IP address

I am setting up Cisco wireless along with ISE 1.3 for guest wireless. The client is going to use the self-registration portal for guest wireless users. I followed this Cisco doc to configure the self-registration portal:
http://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/118742-configure-ise-00.html
I tested this in my home lab and everything works fine. However, at the client users are not getting IP addresses from the DHCP server. This is the same DHCP server that is used for corporate wireless and if you connect that SSID, you get an IP address. I have looked what I configured at home and the client and everything looks the same. In the back of my mind, I feel something is missing, but I can't figure out what it is.
Edit: Not sure if this makes a difference or not, but they are using a Nexus 5K for their core switch and it hosts the SVI for this network.
Let me know what information you need and I will post it.
TIA,
Dan

Hello,
Some verifications below :
Did you verify if DHCP Proxy is enabled in wlc's wlan interface ? Case DHCP proxy is disabled, did you verify if the ip helper address is enabled in Nexus SVI ?
DHCP Scope is enabled in the DHCP Server or is enabled in the WLC ?
Verify if Trunk in the switch is enabled correctly passing all VLANs to WLANs ?
Verify if ACL to redirect configured in the WLC is allowing DHCP Server and DHCP Client to client receive IP Address and ports 8443 to Cisco ISE and DNS to resolve some address and get access to ISE Portal ?
The scenario is Local Switching or Central Switching ?

RRAS 2012 With DHCP Works, Cannot Get Static Address Pool To Connect Completely

Hello Forums Users:
I have set up RRAS/DA 2012 successfully incorporating my AD DHCP server. Every connection works and I see all networks that I have VPN tunnels set up with, which is totally cool. However, I want to assign remote VPN users IP's from a
static address pool - and while the setup completes without issue and the client connects, I can see absolutely nothing. No good pings, no connect to Lync client, Outlook, etc. etc.
I am OBVIOUSLY missing something but have no idea what that is. Do I need to add something (and I really have no idea what that "something" is) to RRAS config so the static address pool (192.168.40.0 in this case) has the same access as
the AD DHCP pool does?
Thanks again for taking the time to check this out and comment.

Bill:
Thanks for the reply.... yes, the idea is to free up a pool of IP's large enough to accomodate all 170 staff. Our current 192.168.2.x DHCP hands out 150, but I need to plan for DR/BCP when other locations (about 110 users) remote in when their
location goes dark.
I already have VPN tunnels between the main locations and a VPN user can see ALL of them when it gets an IP from DHCP. Are you saying that I have to add routes to all the routers/firewalls to accomplish this?
Or would I use IPv4 Static Routes? A network I'd like access to is 192.168.14.0 /24. Would the route look like any of these? Sorry it's not clear what I would use as the gateway (192.168.2.1 is the RRAS server network gateway, 192.168.2.6
is RRAS IP)
Destination Net Mask Gateway Interface
192.168.14.0 255.255.255.0 192.168.2.1 LAN
192.168.14.0 255.255.255.0
192.168.14.254 LAN (
(.254 is the remote gateway)

One user cannot see Inactive Addresses in Account Overview

One user cannot see Inactive Addresses in Account Overview in the CRM 7.0 IC.
This user has the same roles and authorizations as all the other users.
We have also performed a user comparison in CRM and ERP and have also reset the user buffers in both systems.
If I copy the user to another user in CRM and ERP the copied user can see the Inactive addresses. A user comparison shows that the user and copied user are identical.
Any ideas?

Just a gamble, but check his user parameters in SU01.
