Hey

 

I have a Time Capsule (1st Gen). It acts as AP for my Wireless users.

 

I use a repeater for my room, and theres the problem:

 

If I repeat the TC, and somebody (my MacBook 6,1) uses the repeated signal, I cannot reach the TC anymore!

 

TimeMachine: Backup drive not found

Airport Utilities: No Time Capsule found

 

oO

 

My TC is pingable from the repeated signal.

 

Is this a bug or a network-issue?

 

All firmwares (both Repeater (TP-Link) and TC) are up-to-date

 

Hope someone can help

    That is an interesting one.

    That the TC is pingable but not discovered by airport.. stranger and stranger.

    But I am guessing that internet is still working?? Just the TC has now disappeared off the scene.

     

    Try opening the TC share directly. ie in Finder, on the top menu, go, go to server,

    Then try using AFP://IPoftheTC

    If that fails, try using SMB://IPoftheTC

     

    If that doesn't get anywhere, you need to really work through the whole network and obviously the TP-Link is the point of issue. This would all work properly using an airport device to extend the network. Since it is not apple and not able to actually work as MacBook requires, to give things like country code correctly.

     

    Your other big issue here is MAC address of the MacBook (don't mix up MAC and Mac), can be hidden behind the TP-Link due to repeater.. ie universal repeater has an issue that from the main router, all clients connected to the TP-Link repeater are in fact the TP-Link itself. That may end up making internet available but not the TC.

     

    Describe the whole network..

    Main router? What is its IP and what is connected?

    TC as AP in bridge? What is its IP?

    TP-Link repeater, what model? What is its IP?

     

    Experiment.

    If you plug the Macbook by ethernet directly into the TC by ethernet, does it get IP address.. what IP?

    Gateway and DNS address? open terminal and type arp -a.. you might need to ping the TC to populate the arp table.. what does it list the TC as and its MAC address. Check that airport can find the TC.

     

    Do a shutdown and restart of the MacBook and connect back in your room via the repeater.

    When you are connected by wireless via the repeater what address do you get, with gateway and dns?

    If you open a terminal and go arp -a is the TC listed or not.. I think it will have disappeared. And even if you attempt to open it, or some other device connects via the repeater it will get lost.

     

    The answer is to replace the TP-Link with an airport extreme or express .. even another second hand TC.. only remember the ethernet doesn't work when it is in this mode except the express.

     

    Edit..

     

    Another way around the problem.. buy a pair of EOP adapters.. or even better run ethernet, but I am guessing the whole reason you have the repeater is difficult to do that. The EOP adapters are available around $100 or so.. then you can run the TP link also in AP mode. You can set the same wireless settings but different channels to enable roaming. It will also work far better than repeater mode which halves the speed immediately.

    Another expense, sorry, but if you want it to work that is the best way.

    Sorry for the long post. I often figure these things out half way through.

    Internet is working very well

     

    Try opening the TC share directly. ie in Finder, on the top menu, go, go to server,

    Then try using AFP://IPoftheTC

    If that fails, try using SMB://IPoftheTC

     

    Works, both...

    I know what a Mac is and what a MAC is

    TP-Link is working as Uni-Repeater, cause Repeater needs a AP with WDS enabled. TC is working as 802.11b/g and WDS seems to not working here.

     

    Describe the whole network..

    Main router?

     

    I use a Fritz!Box 7112, this one shares its internet to the "main"-switch. This switch is connected to the TC, and the TC shares the connection (bridge) to all users.

     

    What is its IP and what is connected?

     

    I'm working with 172.31.30.x network.

     

    Router: 172.31.30.1

    TC: 172.31.30.4

    TP-Link: 172.31.30.2

     

    TC as AP in bridge? What is its IP?

     

    yep ; see above

     

    TP-Link repeater, what model? What is its IP?

     

    Model: WA-801ND - up-to-date

     

    Experiment.

    If you plug the Macbook by ethernet directly into the TC by ethernet, does it get IP address.. what IP?

     

    Not tested, but an XBox is connected to my TC via LAN, it get an IP from the DHCP over the FritzBox.

     

    Gateway and DNS address?

     

    Gate: FritzBox, DNS: FritzBox (both 172.31.30.1)

     

    open terminal and type arp -a.. you might need to ping the TC to populate the arp table.. what does it list the TC as and its MAC address. Check that airport can find the TC.

     

    Ouput:

     

    fritz.box (172.31.30.1) at bc:5:43:12:40:57 on en1 ifscope [ethernet]

    time-capsule.fritz.box (172.31.30.4) at 0:1f:f3:3d:99:ff on en1 ifscope [ethernet]

     

    Do a shutdown and restart of the MacBook and connect back in your room via the repeater.

    When you are connected by wireless via the repeater what address do you get, with gateway and dns?

     

    Got IP/DNS from FritzBox, always the same (repeater or not, the FritzBox know my MacBook MAC and give me my IP, cause the lease is not timedout.)

     

    If you open a terminal and go arp -a is the TC listed or not..

     

    Connected via repeater: visible, see above.

     

    I think it will have disappeared. And even if you attempt to open it, or some other device connects via the repeater it will get lost.

     

    The answer is to replace the TP-Link with an airport extreme or express .. even another second hand TC.. only remember the ethernet doesn't work when it is in this mode except the express.

    I'm not an beginner about networking, of course, I'm learning this currently. And it seems logical that this issue above should work. TC is pingable and accessible over repeater, but not for Airport or TimeMachine.

     

    Dont worry about your long post

    Very good reply..

     

    I suggest then the issue is that the TP-Link is simply not able to pass the required extra info as used by the airport utility and TM.

     

    If you can open a share via AFP over the repeater.. and copy files?? Then my guess is neither airport or TM are using a straight IP networking.. and whatever other protocol that is involved is not getting through the repeater.

     

    Humour me, and test the setup. Move the TP-Link and run it also in AP mode plugged into the switch or the TC by ethernet. Make sure the MacBook is then connected to the TP-Link wireless so use a different ssid for it. Then see if airport utility and TM works.. if they do. you have isolated the issue to the uni-repeater mode. It will not work with whatever protocol is necessary. I suspect this is the case as the airport utility can find the airport on a different network subnet.. so it is not just using IP.

    Hi,

     

     

    Okay, I will humor you

     

    The setup (TP-Link in AP-mode, different SSID, connected via LAN to Switch) works. AirPort recognizes the TC.

     

    I'll send a mail to TP-Link support - the latest firmware is dated on Feb. this year, so I hope they can fix this issue

     

    Thanks for you help

    Do not expect any response from TP-Link.. or the usual.. the engineers will look at it.. they won't. Apple are a law unto themselves.. making products work with Apple is near to impossible, since Apple make their products to NOT work with others. In fact if you make it work who knows, apple will sue you for patent violations. Repeater is a totally non-standards approach to wireless networking. What works with one brand of wireless will not work with another.. there is no proper standard and even WDS is not able to work amongst the same company products if they use different wireless chipsets. You must use apple products to do repeater mode to other apple products.. !! Have fun.

    Another comment.. because I cannot help myself.. wireless repeater is poor way to do things. It is flakey and tends to be unreliable at critical points.. ie there are gremlins in there that ensure at just the point when you need the repeater to work it will fail.

     

    Always do wireless in a single hop.. never double hop.. it reduces speed by half immediately to add to the other issues. Use ethernet to connect AP's. Even EOP adapters are better than wireless repeaters. Faster and at least if they work do tend to be reliable.

     

    The way to get long range wireless is one hop using high gain directional antennas. These are expensive. For whatever reason high gain omni-directional are cheap as, whereas directional adding a bit of tinplate cost a mint.. but with reflectors.. which are really ugly.. or better using panel antennas or home made biquad you can get serious range out of domestic equipment. Biquad are easy enough to make yourself if you have any handyman skills at all.

    I did a design using an old 2db dipole.. and they work great.

    Updates Updates Updates.....

    It seems that TP-Link would fix this.

     

     

    Dear Mr. Kluth,

    thanks for your report. Our headquarter in China has confirmed that the TL-WA901ND has a bug with forwarding Bonjour protocol packets. We are working on a solution.

  • LaPastenague Level 8 Level 8 (41,140 points)

     

     

    By the time the firmware update comes out.. you will have a different setup.

     

    Happy waiting.
