• Time Capsule has lost the Internet connection and DNS servers

  I use a Time Capsule for Time Machine via Ethernet backups for a couple of years, use it in mode bridge taking its Internet connection directly from my router and connected in turn by Ethernet to my iMac. (Most of the time that I also had wifi off on my iMac and took my Internet directly via the TC Ethernet connection.) A few months ago I upgraded to El Capitan, and the TC has lost its connection Internet (flashing yellow). A few days later I drove back to the Yosemite (for other reasons - Mail had gone mad) to restore a backup of the TC and everything was fine again for a few months. It may or may not be meaningful I plugged TC yesterday to new laptop for my wife to support for the first time, and this laptop is running El Capitan. Since then, the TC has once more lost its Internet connection and DNS settings and is stuck on flashing orange. By clicking on the 'Internet connection' status alert, tells me that the TC is not a valid IP address.

  

  I have reset the TC, repeatedly and reconfigured but all without success. After consulting the other discussions, I also tried giving the unit an alphanumeric name with no spaces & special characters and change the IPv6 "Link-local" configuration only, but this did not affect the result. And I updated the firmware for good measure. Then I unplugged overnight and carried out a full power cycle the steps recommended here, restart the router, TC and the computer (and performed a factory reset on the TC, while the router & computer was turned off). After doing that, the TC has become undetectable by AirPort Utility, until I have reset reconfigured once again, he and ended up in the same place.

  It may or may not be important to mention the following:

  1 when you set the TC after a reset, I repeatedly selected the option of adding to an existing network instead of create a network, but the installation wizard who ignored each time.

  2. in the installation each time, this point, I shows me the following, which seems to suggest that there is a problem but don't say so explicitly:

  

  I would be grateful for any advice.

  Weird how everything's going well for a few years and then crazy when you have something will change.

  El Capo adds some network problems more... but something could be fundamentally wrong with the installer.

  Your current configuration, it is apparently bridged but cannot get an IP address. The address 169.254 is give it since it's self generated.

  You need to do a manual installation. It simply means the Assistant is unable for any reason to be your network so start over and do it manually of misfortune (wow, or also possible misery, woah being where you are now!) to go...!

  1. I need to know what modem you are connected. Make and model please?

  2. the most important. What is the main router on your network or a modem?

  I gave the edge to make manual settings a few times. Somehow my instructions for Yosemite/El Capo got lost... I'll try and hunt down them. In the meantime, the basic method remains the same.

  It is not so difficult... You just know where you're going before you start.

• Why is-36 of Firefox on Windows receiving connections from DNS servers? Option network.dns.get - ttl

  Following update Firefox 36, my firewall was flooding asking me to allow external connections from the Internet to my browser. Looking at it more closely, Comodo Firewall indicates that external websites are trying to connect to Firefox, port 53 to an arbitrary port on my machine.

  If I disable the option FF36 new network.dns.get - ttl, it stops. I can't find any documentation or help on this option.

  Why Firefox do this? Is Comodo incorrect when he labels it as an external connection attempt? (It has normally been extremely good to differentiate the incoming and outgoing traffic). I guess that Firefox is trying to determine the TTL for DNS caching, but it is not make sense why DNS servers then try to connect to me.

  I am reluctant to create a firewall rule to that arbitrary Internet connections on my machine are OK as long as their origin on port 53, tips on how to manage all that this new feature is firmly States would be appreciated.

  Thanks in advance for any help.

  Hi grammarye,

  Yes, you're right in thinking that Firefox is trying to find the TTL value. This is new in Firefox 36 behavior and was presented as services frequently changing DNS records (such as Cloudflare) were not working properly for Firefox users.

  Firefox makes asynchronous DNS searches - which means it will make a DNS query and then proceed to perform another task instead of waiting for an answer.

  Your ISP DNS server puts in cache only TTL an area for a short time, so if it does not the current LIFE expectancy, he will interview with other DNS servers to find.

  IANAE, but probably what is happening is:

  1. Firefox tries to find the DNS record for the domain that you want to connect to
  2. Your ISP DNS server does not have the current LIFE expectancy, then connects with other DNS servers to find
  3. During this time, Firefox lingers with something else
  4. DNS server, then reconnects to give you full DNS, including the TTL check
  5. Comodo sees the packets of the DNS server and panic

  I completely agree that arbitrary ports of white list is a bad idea, but in this case, the behavior is completely harmless.

  You can want to whitelist Firefox in your Comodo Firewall, or continue to let network.dns.get - disabled ttl.

• Since the update, I get a message "unable to connect". Explorer Windows has no problem connecting to ADSL. Help, please. I don't like Win Explorer! Thank you

  Help, please. I can't access the internet through my DSL since the upgrade.

  Your firewall is not recognizing the new version of Firefox. Remove Firefox from the list of allowed programs in your firewall, restart Firefox and go to any website, give Firefox the permissions he needs access to the internet.

• D7000 will not connect... Help, please!

  I bought a nighthawk d7000 and could not get it to connect. I thought it was my connection speed WiFi, because it would take me to the site of router configuration but should then always be with configuration protocols and detection of Internet settings still would take me again through the steps. I had a technician who confirmed that it was 11mbs in the House and to the router. I called netgear who (wrongly) told me that I needed to have the account information provided by my ISP provider. I called them and they told me I was not running a pppoe and therefore does not need. I called netgear and they told me that I had to call my ISP (for something), and then the call conveniently dropped as technology which was trying to tell me what to do clearly did not know what she was doing.

  It seems that somehow, I probably need to configure the DHCP settings and perhaps manually assign an ip address, but honestly I'm new on this and I have very little idea as to what I'm doing.

  Ideas, any help would be greatly appreciated!

  It is more likely is not supposed to because I had / have no idea what I'm doing. Thank you for your response. I had it works, but only after you have spent hours bouncing back between netgear and my ISP.

  Ultimately the router should be configured to 'type of Internet' ADSL equal and the ip address is set to 'use my computer.' it finally got all white lights.

• "No video in" error when connecting two SX20! Help, please

  Hello everyone

  We have problems to connect our two SX20 telepresence equipment, which has a bridge. When you call one SX20 on the other, once the connection is established, the message "no video in" appears on the screen. How to solve this problem?

  Also, we want to call the SX20 of jabber accounts video from computers and vice versa. How can do us?

  Currently, we only connect the two SX20.

  This is the deployment, we want to have.

  

  Thanks in advance

  In most cases no video is caused by firewalls and other devices with a logic of layer-3.

  You also had a different thread open material a generic question of deployment.

  Maybe you have a cisco partner or an external consultant who can help you with that.

  As you also said mobile devices, if a 3rd party there is always a chance that

  devices do not understand well the other on road signs or the face of the media.

  But at least two sx20 should be able wiith all problems to send and receive video

  If deployed stand alone or with a call like vcs or cucm control.

  Which brings back once again, check the network ;-)

  Please for your own good do not use myriads of download of driver from the web sites.  They are wrong and ruin your computer.

  Your main source should be OEM for your computer.  Go to their support page and provide your model number.  This should lead you to the driver you need.

• Bangin blackBerry smartphones ' my head against a wall re: Internet e-mail configuration. Help, please! I'm desperate.

  Argh...

  Have been trying for days to set up my email of internet.

  I bought an unlocked 8310 (AT & T) curve for my T-mobile account.  Everything works so far, including browsing the web, but I can't configure my Internet email.

  There is absolutely no icon on the phone to do this, I searched all the options that was suggested to me.  The only option I have is to set up an Email from the company, which I did not.  I have been in discussion with AT & T and TMobile and have entered my PIN and IMEI code on both sites to try to set up, with nothing working.

  All the ideas for the poor ole' me?

  Thank you

  Phew... I had figured it out.  TMobile sent me incorrect service for my telephone books.  Thanks for responding!
