I notice that after upgrade 7.7.1 on the Airport Time Capsule 802.11ac, whenever a time machine backup starts on any Mac, the Internet connection disconnects for all Mac and iOS devices, at least for a minute.

 

But the ADSL2+ modem is still connecting to Internet without disruption.  Airport Utility shows Internet disconnection until a few minutes after the Internet connection re-established.

 

Any explantion or similar experience?

Airport Time Capsule 802.11ac, OS X Mountain Lion (10.8.4)

    It is a new one to me.

     

    Are the computers backing up over wireless? Wireless is a shared media.. and the load of a backup is so high all the other computers and devices will expect to suffer a slow down.. but should not disconnect.

     

    Can you test by using ethernet on the computer that backs up.. does the internet still disconnect?

     

    And you can also test by setting a different name for 5ghz.. force the backing up computer if possible to the 5ghz or force it to 2.4ghz.. whichever .. so you can see if one band is affecting the other band.

     

    That should give us something to work on.

    Double NAT is not ideal.. but anyway that is unlikely to be the issue.

     

    Does the belkin run wireless.. if so connect a computer direct to the belkin wireless and see if it is affected.

     

    Disconnections do seem to be a feature of latest firmware in both the Gen1-4 and Gen5 TC and corresponding AE are also affected.

     

    Ethernet not working.. something weird and wonderful there.

     

    I would try again.. turn off wireless in that computer.. reboot the whole network.. restart in correct order .. modem.. TC .. clients.. and then test the ethernet whilst other computers are doing backup and see.. all sounds awfully windows networking to me.

    My 2009 TC did this and my new TC ac does it some times as well. I spoke with Apple and they said it was correct as when updates start their atr a lot of transfering files.

    Try using a switch between the modem and the TC.

     

    Or a crossover cable. People are definitely reporting issues in some situations with the WAN connection of the TC.

     

    This is sometimes present and sometimes not. Is the modem also a router or is the TC doing router duties.

     

    A cheap 10/100 little switch can be purchased for a few dollars now.. it can help with timing issues. And the Crossover can help with the auto connection.

     

    See this thread.

     

     

    Crossover cable to fix issue of connection to ONT or cable modem.

    The OP did some careful testing near the end and found either solved the problem.

    This happens to me too! I thought I'm the only one with the problem.

    The new AE and TC use a broadcom SOC .. that means it is a full processor and router on a single chip. .it runs at 1100mhz.. ARM based. A9 core.

     

    The previous Generation TC and AE ran a Maxell processor of 1200mhz.. and actually was faster at least on the disk transfer side.

     

    See ifixit for the breakdown of the TC and AE so you can see the processor.

    This links to the AE as well.

     

    You can also see the review of the AE Gen6 here.. as well as earlier versions if you set the charts to show earlier hardware.

    cf Gen5 AE http://www.smallnetbuilder.com/wireless/wireless-reviews/31564-apple-airport-ext reme-gen-5-reviewed

     

    The new version products are much closer now to the standard AC routers by dlink and Asus than previous ones.. which were more NAS design.
