5Th Gen AE Does Not Assign IP Address in Bridge Mode

I have three AEs in my house...two of which are 4th gen and one is 5th gen, and two of which are set up as bridge (a 4th gen and a 5th gen). The 5th gen does not generate ip addresses reliably...everytime I go to the room where the 5th gen AE is I have to turn off the wifi on my device and turn it back on to get an ip address. This happens 100% of the time. I have tried my MBP, as well as my iPhones (4s and 5.) I also noticed the ip address that is being assigned for the bridges is of totally different denimination. The 4th gen bridge gets an ip of 10.0.1.4 where as the 5th gen gets a 192.168.1.76...the DHCP address range for the main is 10.0.1.2 through 100 and it should be assigned one of those ips. I'm kinda suspecting this is why the bridge is not working properly. I just don't understand why this unit is acting this way. Any input to help solve this mystery will be greatly appreciated. CHEERS:-)

Did resetting to factory help this issue? I'm having the same problem with my 5th and 3rd gen AE's. I've added a new router (pfSense) and only need the AE's for access points. The following is the result on some problem tracking:
Working on my network ip addressing issue. I shut everything down. I brought up my internal wired network of pfSense router, internal switches, appleTv units, printers and a couple of computers. All Addresses were correctly assigned. I released/renewed the ip addresses to check if the address assigned would remain correct, and this test passed.
I then connected my cable modem to the internet, which connected with no problem. I then again tested release/renew of addresses, and this test pasted with no problems. And I had internet access.
My internal network follows the 10.0.1.xxx address range. I leave 20-99 open as my dynamic range, and assign my AppleTv, DirecTv, SlingBox, and MacMini server to static addresses via MAC reservation. All these are functioning correctly.
Final test. I add my Airport Extreme 5th gen, which is in bridge mode, with no guest network, and the light turns green. I open up my MacBook, connect via WiFi, and the address is 192.168.100.34, not correct. I turn WiFi on my MacBook off, then I turn it on, after three cycles I get a correct ip address.
I confirm via airport utility my settings. I see nothing to change. I replace my Airport Extreme 5th gen , with my older Airport Extreme 3rd gen, and I once again get a 192.168.100.22 address which is not correct. I cycle the WiFi setting in my MacBook and after a few cycles, I get a correct address.
My DHCP server is an older Dell system running the linux based software pfSense. I made this change after I started getting bad IP addresses from my Airport Extreme 5th gen. My cable modem is a Zoom 5431J DOCSIS 3.0. But my first test was verifying the assignment of addresses from pfSense, without the cable modem.
I've powered off both Airport Extremes and have checked the settings. Not sure what else I might try with these Extreme units.

DHCP server does not assign IP addresses SG500 firmware 1.3.5

good day collegues
has any of you come across the following issue:
my switch (after upgrading to the newest firmware 1.3.5) does not assign IP addresses to some of the hosts.
after a couple of hours I managed (do not even how) to force my switch to assign IP addresses only to some of the hosts.
still some of them cannot get the IP address and remain with "funny" IP address like i.e. 169.254.100.100
additional info
1. if I boot my switch with the previous version of firmware (1.3.0.6) everything is OK. all my hosts get correct IP addresess
2. the hosts which do not get IP address were perviously entered in stat host table - now removed, ARP cleared, etc, everything many many times rebooted.
I ran out of ideas, could you pleae give me some hints ?

Hi Andbor, please make a backup config of your file, factory reset the switch.
After this, manually configure a DHCP scope without any other configuration.
Just something simple like this
ip dhcp pool network GUESTS
address low 10.10.14.1 high 10.10.14.254 255.255.255.0
lease infinite
netbios-node-type b-node
default-router 10.10.14.254
dns-server 10.10.10.1 62.233.233.233
Verify your machine receive IP address with no other configuration.
In some ways, I'm afraid some of your connections black listed due to the arp inspection.

Kenwood X991 & iP200 cable with iPod 5th Gen 80GB does NOT work correctly

I have a conundrum. My wife has the 4th Gen v1.2.1 iPod 30GB which works fine on my Kenwood X991 Head Unit. I recently purchased the "new" 80GB iPod 5th Gen with the latest version "1.0.2" which does NOT work properly. The iTunes software tells me that this 1.0.2 is the latest software.
When I attach my iPod to my stereo, it states "Reading" for eternity. It DOES play music but only plays Alphabetical Order ONLY. There is no ability to stop, change, fast-forward, reverse, etc....the only thing you can do is click "Source" to change to CD Player or Tuner, etc...
Does anybody out there know what is going on? I have a request into Kenwood as well. Thanks in advance for all your help!
-Kingofbytes

Thanks for the help. It's an iPod Classic then 80GB. The unit plays when plugged in but does not allow searching, or switching songs nor displays as it is supposed to. My wife's 30GB works with no problems. Of note:
Her 30GB = v1.2.1
My 80GB = 1.0.2
Mine is newer by about 6 months. Both are the latest software according to the screen.
Kenwood has said to "reset the head unit" and "make sure I've got it plugged in properly". I need to try the reset part next but the last statement is funny to me. I can install a head unit, amplifier, re-run all speaker wire, install a Dual 10" subwoofer box, solder and wire tie all connections from a factory unit to a 3rd party Cable manager kit, but I need to "make sure" I know how to plug in an iPod cable.....laughable.

5th Gen Ipod does not show photo tab under preferences

I am trying to get pics onto my Ipod. The ipod tutorials suggest going to a photo tab which I do not have. I can not update the Ipod because Itunes 7 says that Ipod is already up to date? Is anyone having this problems?
5th gen ipod Windows XP Itunes 7

The ipod tutorials suggest going to a photo tab which I do not have. I can not update the Ipod because Itunes 7 says that Ipod is already up to date?
can you check something for me? what icon is showing up in the itunes sourcelist? is it a wee picture of your 5th G, or does it look quite different?
what version of the firmware is being cited in the "summary" tab you see when you select the ipod in the sourcelist? is that the same version that you see in the "About" screen on your ipod?
Where's the iPod About screen, and what's in it?

5th gen Ipod does not load video on Itunes

My 5th gen color Ipod recently began having problems when I updated Itunes software.
The video that is on my Itunes library does not transfer when synced to Ipod.
Video on Macbook plays but is not recognized by Ipod and does not load.
Any help is appreciated.

Check your settings for sync. The default for videos are that only unwatched videos get synced.

5th gen extreme does not play well with 1st gen express

I have extended my AP extreme (5th gen) with a 1st gen AP express. Once several devices connect (several iPhones/iPad) the network goes 'bad' after some undefined amount of time (maybe an hour or less). Symptoms are very slow internet access or devices dropping off wifi (except for my iMac which is close to the AP extreme). The AP express may disappear from the AP utility. The solution seems to be to reboot all AP's. I have reset the 1st gen to factory default several times.
All AP's are running latest firmware.
Before I give up and buy a new AP express, any ideas.

Would you agree that something is causing the connection problems?
Teens often hang out on bit torrent sites (videos...(don't ask )...games, other garbage) that demand more than the wireless can deliver. Things slow down and lock up on the network.
Might be a possibility. If things always seem to go downhill after the kids get online, that is probably a clue that they are on very demanding sites in terms of bandwidth.
Until you find out what that is....bit torrent sites.....a nearby cordless phone...other wireless networks or wireless security systems in the area, microwave interference, BlueTooth devices, etc....the problems will continue to repeat.
I once had a similar issue a few years. The wireless would operate fine for 4-5 hours, sometimes a day or two and then suddenly slow down...sometimes crash. I spent days trying to locate the problem....took the devices to the Apple store, where they checked out perfect, etc.
Then, one day by accident as I was working at my desk in the home office, I noticed my neighbor....across the street....coming out of his house talking on his cordless phone whey my wireless network suddenly slowed to a crawl. By the time he got to his mailbox on the street, my wireless had crashed. Now I knew what was slowing down and crashing my wireless.
Fortunately, we were good friends, and he usually remembered to leave the cordless phone inside his house. But, when he didn't, I knew exactly where he was and what he was doing without even having to look out the window.

5th gen ipod does not connect to mac desktop or itunes

My ipod does not connect with my desktop or itunes (ie when I plug the ipod in using the original USB cable nothing happens--no charging no recognition that it has been connected). My nano does work with the same cable so I know it's not that. I've followed the support instructions resetting, downloading the latest software and restarting. I cannot, however, restore since the first step of the instruction is to connect the ipod and wait for it to show in the source list in itunes. It is also interesting that when I use the car charger the ipod does charge and shows the charging icon.
Any suggestions?

I guess i can lend my voice to the conversation. my ipod "locks up" when i connect to my computer also. i just updated itunes and have not been able to connect. there is no ipod folder on my computer when i search through ""finder". i have to "reset" it after i disconnect to continue to play it. i have done everything short of "restoring" due to i have over 3000 songs and i'm unable to back up. the manuel refers to a disk to update. i can only play songs, and recharge. need help to.

Time capsule does not allow me to select bridge mode or manual setup

I've got an Aztech combined router and modem. I have disabled its wireless feature, and from what I have read, understand that I need to set up the Time capsule in manual mode in order to have a bridge connection (?). I've reset the TC several times, but the manual setup option or the bridge connection option does not seem to be available. I can backup fine, but want to use the router facility given the price I paid! If I try to edit the router mode with the TC already setup, the option to change it is greyed out (DHCP & NAT)
Bit of a novice at these things, so any help greatly appreciated!

You need to make sure your ISP supports pppoe as a method of authentication.. if so then you must bridge the Aztech modem.. so it no longer handles the connection.. look up the manual for the modem to find out how to do this.
With the modem bridged.. reset the TC and the airport utility should recognise that it is now needing to run in router mode.. you are running Lion or ML and v6 utility has no manual setup.. it auto sets bridge. You need to force it to router.. but by default from reset the TC will be router.. you then need to setup pppoe client.. have no idea how to do that in v6 utility.. I am pleased to say!!
If you run lion.. download and install the v5.6 utility.. then all your troubles will go away.. it is a tool.. rather than Lion version being a toy utility.

SG500 - DHCP server does not assign predefined static IP addresses to hosts

hi guys
I upgraded my SG500 switch firmware to 1.3.0.59, since there is a new functionality DHCP server v.4
well I must say I came accross the issue I cannot solve. DHCP server assign dynamic address - no hassles.
troubles start with static IP hosts.
I defined a couple of hosts with static address within the correct subnet. I tried with hardware address and client identifiers. no luck. my switch does not assign the IP address I assigned to the suitable mac address. to define it I use both CLI & Web.
no of them works. any idea ?
below the cut from my config:
ip dhcp pool host HP-Ellite
address 10.10.11.7 255.255.255.0 client-identifier 01:d8:d3:85:cf:09:72
client-name HP-Ellite
default-router 10.10.11.1
exit
ip dhcp pool host VAIO-Z
address 10.10.14.108 255.255.255.0 hardware-address 54:53:ed:1c:a1:46
default-router 10.10.14.1
exit

Tom, thnkas for a quick reply...
look, usually it is pretty easy to manage an issue with so precise instructions. but this particular time it is not.
as I understood the "dhcp option 61" is nothing more than "00" which go before pure hardware address.
so, coming back to my example from the first post
with this configuration, my switch assigns 169.254.110.130 255.255.0.0 address
ip dhcp pool host HP-Ellite
address 10.10.11.112 255.255.255.0 client-identifier 01:d8:d3:85:cf:09:72
client-name HP-Ellite
default-router 10.10.11.1
exit
with that configuration, my switch assigns 10.10.11.11 255.255.255.0 address
ip dhcp pool host HP-Ellite
address 10.10.11.112 255.255.255.0 client-identifier 00:d8:d3:85:cf:09:72
client-name HP-Ellite
default-router 10.10.11.1
exit
otherwords "00" does not work as explained (unless I misunderstood the meaing of dhcp option 61). my switch assigns first available dynamic IP address. atlhough the arp table is cleared, dynamic address table is cleared as well. swtich is rebooted, host is rebooted
once I change hardware address prefix to "01", my host asign itself 169.xxx.xxx.xxx adress.

Ipod (3rd gen.) does not mount to iTunes

My ipod (3rd gen.) does not mount on iTunes (using a Mac). When plugged in, it appears on my desktop as if it were a jump drive.
I was planning on re-formatting it with Disk Utility but I'm not sure if this is a good idea. I also realised that the Format is listed as Windows NT File System (NTFS) when I have the disk utility window open. If I need to format with Disk Utility, what format option should i choose? (i.e. Mac OS Exteneded (Journaled), Mac OS Extended etc.)
Thanks in advance!!!

Now when I connect the Ipod to my Mac, it mounts as a Device on iTunes. I want to sync only a few items from my library onto this iPod - when I attempt to do this (by either adding the specific music to the "music" section on the iPod or creating a playlist and using Autofill to fill the iPod), the iPod says that it has Synced but when I disconnect the iPod, there is no music on it. Why?

WRT610N V2 wired as 2ndary router to wired router, does not give IP address wirelessly

My WRT610N V2 is wired as 2ndary router to a wired router but it does not give IP address wirelessly to connected PCs.
It is getting DHCP IP address in the 192.168.1.xxx range from the 1st router, on its internet port, and issuing properly an IP addresses in the 10.10.1.xxx range thru its LAN port when wired to a laptop.
But if I connect to its 10.10.2.xxx wireless network with another laptop, the wifi adapter utility software shows the laptop is connected, but the laptop is not receiving an IP address. Please help in correcting this, as I need to use this router to give internet access wirelessly to guest laptops.
I know DDWRT does this kind of bridging with secondary DHCP when both routers are connected wirelessly, but it seems to me that if the 1st and 2nd router are wired together, DDWRT shuld not be needed for 2ndary HCP to take place.
And 2ndary DHCP is indeed working for those laptops wired to the 2ndary Cisco router: seems to me it should be able to do it also wirelessly.

Ipod shuffle 4th gen device does not appear in latest version iTunes

ipod shuffle 4th gen device does not appear in latest version iTunes

Mine is not recognized by PC-Windows, nor Itunes, and not by the "Mass Storage Device" removal Icon. I've done all the diagnostic tests, Uninstalled Itunes then reinstalling, etc.etc to no avail. Yet never had a problem with old generation Ipod, (died of old age) and Gloria's Ipod after two plus years is going strong with never an issue. I belive Apple is having significant problems with the 3/8 inch shorter newest Ipod generation. If your Ipod is still under warranty you need to call Apple support.
