Are not relayed queries ARP on bridged Airport Extreme

I have a router Xfinity and set up Airport extreme as a router jumpered to connect LAN devices on a different floor.

Looking at network traffic, I noticed that the ARP requests are delayed or not relayed on the router bridge making it appear that these devices are offline.  These applications should get relayed?  Is there a special way to configure this option to get there?

I used tcpdump to monitor network traffic.

It is one of these small problems that make it difficult to use sometimes Apple routers... ARP is a problem.

Apple recommended using the extreme double NAT... I don't like it, but you can see why.

I recommend using static IP approach.

Re: time capsule Airport Guard disconnection

You sound like you know what you're doing, so it's not difficult for a person with some networks nouse.

Post again if you find this difficult.

One thing I added is the default domain in the Airport extreme is local and it seems never even change in bridge... I doubt that you can change the domain of the Xfinity router setting but if you can do then. Do local as well since you can not change the configuration of the router from apple.

Finally if you still want to use the bridge... try connecting to the WAN port ethernet port LAN of the extreme... In bridge WAN is connected to the local network, but it may be less accurate in bridge, you can even set a static IP address and with the connection to the LAN port ethernet customers should get all the information directly from the Xfinity... If your extreme is the KT model... There is definitely something wrong with the extreme WAN.

  • Suddenly our router keeps losing the internet.   The representative of the Cox says that IPV6 on the router is not compatible with the Cisco modem.   I'm turning it off?   Who is?   All started 3 days ago.   Have to reboot AirPort Extreme

    Suddenly Tuesday, our wifi stopped working.   Cox can not see anything on their end.   So far, we had to restart 5 times.   I finally realized that it is not the modem (Cisco), but our AirPort Extreme.   That's all that needs to be restarted.   I talked to a technician that I got to know, and she said that this week this problem started occurring with customers who have extremes of the airport.   Something about the airport in IPV6 and this is not compatible.   Before systems were PVI until the numbers came out (?)   In any case, she said Cox could not fix this, that I needed to talk to Apple to see if I could disable IPV6, at least for now.   I think I see how to do this, but does it make sense to anyone?   We have a new modem, installed in January, Cisco DPQ3212, good speeds, no issues whatsoever until this week.   There are also 2 other friends here (Scottsdale, Cox) with extremes of the airport.   Any suggestions?

    Cox has made a number of recent changes to their service, and they are trying to integrate IPv6 technology into their signals. They have not fully implemented the changes that must be made, and not commit to a date where things will be fully installed.

    Everything was fine until Cox implements these recent changes, and now Cox is blaming the problem on Apple. Apple has a different answer, as you can imagine. It is typical among manufacturers... blame the other guy.

    Apple routers are picking up some of the information they need to work with IPv6 and Cox, but since Cox has not completed the process, you'll probably best results trying to not use IPv6 with the airport router at all until you receive word of Cox that their systems are ready.

    The bottom line to this problem can be resolved by asking "What has changed".  The answer is Cox has changed.

    Configure your router to the airport most convenient to use IPv6 local link parameters only for now, to see if this will help.  You will not be able to realize all the benefits of IPv6 at the moment, but I hope that things will improve.

  • What to do if the reset button does not work on the Airport extreme a1408 w / Password lost?

    What to do if will not work the Reset button on Airport Extreme a1408? The password is lost (bought used). I spent several hours trying every method I could find anywhere on how to reset; soft, hard and default. Airport utility doesn't let me do anything without the previous owner password. I can't get him.

    Can anyone help?

    At this point, your only hope is to open the AirPort Extreme to try to repair the reset button... If possible. This link provides some tips on the process to open the unit.

    Honestly, it isn't easy, unless you're a guy real DIY, you can buy an A1408 used on Amazon for about $35-40.

  • AirPort Extreme can disappear from the network

    I have an airport Time Capsule 802.11ac 3 TB, implemented as my router, connected to a cable modem Comcast.  I also three units AirPort Extreme 802.11ac connected via an Ethernet cable and configure in Bridge mode.  The settings were all made with Apple AirPort Utility, using the default settings.  All devices are new, and have the latest version of the (7.7.7) package.

    My problem is that one of the SSA keeps disappearing from the network.  The AP utility shows all devices, but unity of the 'room' is still "missing in your network.  When I restart the device by unplugging the, the unit seems to work fine for a little while.

    Because the problem occurs on a unit, I think not that it is a question of ISP or OS.

    Has anyone else had a problem like this, and understand you?

    It is not uncommon.

    There is a real problem with apple DNS...

    What modem do you use?

    Actual spending brand and model please... It is probably not related, but it is useful to know the complete network configuration.

    Question I would like to change.

    1. your names are too long and contain spaces.

    Use any short names, without spaces and pure alphanumeric characters. Names must be less than 10 characters... all names... both network name.

    See Pondini for questions that arise with more long names... and that was before Apple changed network SMB.

    http://pondini.org/TM/C9.html

    2. the WAN port on the AC model TC and AE are not reliable.

    In bridge, what do you do better move the connection to one of the LAN ports...!

    3. you have an unreliable ethernet cord or if it is installed in the wall a bad Jack which is down to... This happens especially in that self installed ethernet... and even the ordinary electrician has problems... sometimes wrongly wired a pair of broken. You should test all ethernet correctly and make sure have full gigabit connections.

    4. use static IP via both a dhcp on the TC and AE reservation jumpered on the internet tab. Least IP moves the less work THAT DNS must do to stay.

    If you have still questions after.

  • Airport Express is no longer connect to Airport Extreme

    OK, it's kinda a complicated question.  For starters, I will describe my current setup:

    Cable modem Motorola-> Airport Express #1-->(Ethernet over powerline)-> Airport Extreme-> multiple Airport Express for AirPlay

    Airport Extreme and Airport Express #1 are put in place to create wireless networks, with different names for 2.4 Ghz and 5 GHz frequencies.  I love this configuration because it allows me to play music simultaneously on the four different speakers hooked to my Airport Express units while offering good coverage in my apartment together.  It worked perfectly until two days ago when two of the Airport Express units lost their connection and are now flashing yellow.  I tried to restart the Airport Express and Airport Extreme, but nothing helped.  When I launch iStumbler, it looks like Airport Express #1 and Airport Extreme both create networks of right, but who is the Airport Extreme 802. 11A instead of 802.11n - don't know if it of a problem or not.  I suspect that the Airport Extreme is not working properly because when my wireless connection when you use my iPad near the Airport Extreme, that used to be solid as a rock, is now uneven intermittently.

    Any ideas on how I can solve this?  Thank you very much!

    It sounds like your extreme is the very old Gen1 or Gen2 model without dual band.

    Back to the factory and start over. It's the best way to solve problems... reboot is worth a trial, but in the end, you sometimes just have to redo the installation.

  • Why my airport extreme is overheating?

    For the last week my Airport extreme did evidence of a status message saying that it could be overheating. It was behind my iMac so I moved it to the desktop to ensure it becomes quite convenient, and he still has questions. Firmware is up to date, and the airport is barely more than a year. I received it the year last for Christmas. Not sure what is the cause. Is this just a hardware problem?

    I guess two things:

    1. There is plenty of space around the base station itself, and
    2. The room is held where the base station is not excessively hot.

    Your AirPort Extreme 802.11ac has an internal fan to the top of the unit and air is drawn in and exhausted by the bottom. It would be possible to have a few "dust bunnies" in the database or that the fan is defective.

    To get a better idea on what's inside, please look at the following disassembly of iFixit for this device.

  • Second Airport Extreme in Bridge mode, ethernet ports does not

    I have two routers, I want to use. The first is a time Capsule (old model 2 TB) connected to a single cable modem. The second is an Airport Extreme (also a little older, the 'flat' last body model until they began to sell towers). Both have the 7.6.4 firmware.

    The problem is that I want to use the second to extend my network, but I don't want to use wifi. I have the second of the WAN port connected via an Ethernet cable to the network served by the time Capsule, but when I launch the extreme in Bridge mode with a Mac Pro plugged into one of the ports ethernet to the extreme, it says it is not connected to the net.

    Y at - there a trick to getting the second router work ports ethernet when used in this way?

    Thanks in advance!

    What version of the bridge are you using and what is your OS?

    Please how much is left in your main hard drive.

    By default, the bridge cache is located at: -.

    Note that cache bridge could be very large depending on your use of the product.

  • Previews in Bridge CS5 are not sharp

    The Panel in Bridge CS5 preview images are not strong (almost blurry). Also when I select an inch and view it using the method of the space bar (of the bridge) the picture not sharp. Anyone has any idea why? They look fine in Bridge CS4. I searched for a setting, preferably without result. It doesn't matter if it's RAW or JPG (same results).

    When I select an image and view using the space bar (in the finder) looks sharp/normal.

    Thank you.

    You generate previews monitor size (an option in preferences)? You will need purge the cache for the records after making this choice.
