Ok so I was just on here yesterday about having problems with my Apple Time Capsule/Airport having problems with connecting to the internet. I got the fix for that and the problem was solved. However, I now can't seem to acces home sharing between my Apple TV and macbook pro for instance, nor can I access any of the files saved on my Time Capsule or perform any Time Machine functions (My Time Capsule doesnt even show up when I try to look for it) On top of that, when I try to access Airport Utility from my main computer that is connected to my Time Capsule, I can find it no problem. But when I try to look for my time capsule on my macbook pro with Airport Utility, it says I have internet , but it cant find the Time Capsule at all....So, my question is what the heck is going on? And how do I resolve these issues? Please any help would be appreciated.


MacBook Pro, Mac OS X (10.7.2)

    Lion and TC.. they lose each other on a regular basis.. restart the TC and all is good for a couple of hours usually.. there is no fix .. I don't think Apple even knows there is a bug.

     

    Wireless is a key issue.. if you plug in with ethernet it will probably go away. Is the main computer connected by ethernet??

     

    Update install of lion also has much more issues than clean install from what I am reading. It is not uncommon issue if you read back on the forum.

    I have called Apply about this and they blame Comcast. Comcast comes out, checks everything, says it is Apple. MANY calls to Apple, not success. Oddly I NEVER had this problem with DSL, so there is some subtlety.

     

    I have the latest and greatest Time Capsule and Comcast. Here is the weird thing. If I have one network set up, then occasionally that network will wedge. If I set up a 5GHz and a 2.4GHz network, then one of them (usually the 5GHz) will wedge. I saw this with a previous Time Capsule, Apple said call Comcast. They checked it out and said it was Apple's problem. Apple said maybe you Time Capsule is bad, so I bought a new one. The problem persists.

     

    Tonight it's not complely wedged, but super slow. The 5GHz network is getting 0.45Mb/s while the 2.4GHz network is getting 17Mb/s. Both are coming in from the same Comcast cable modem. Apparently the Time Capsule treats them as separate.

     

    Is it the cable modem or the Time Capsule. I am betting on the Time Capsule, since rebooting it fixes the problem. Resetting the cable modem does not.

     

    Apple is NO HELP at all. They say reset the Time Capsule. Did that fix it? Yes. Problem solved! No, problem not solved. It will happen again in a few hours.

     

    Here's the traceroute. Note what happens a few hops away. At hop number 7 the ping times go up by a factor of 200.

    Blaming cable is so so unlikely.. cable service is so reliable for most people.

     

    If reboot fixes it the issue is the TC.. but why.. that is the unknown. Apple sure aint helping their cause.. but I can tell you from reading and posting on this board for the last 12months.. when it happens to people they end up buying another router.. relegate the TC to bridge and use it for TM backup.

     

    Delay in the traceroute are common and it is not conclusive as to the cause. . most likely not the TC.. that is the router at that spot overloaded.

    It would be nice if Apple would take it seriously, but they seem to not be paying attention at all. Many people as evidenced by a quick Google search are having issues with the TC and cable modems.

     

    As regarding the traceroute, it is CLEARLY the TC. One network it's fast (2.4GHz) and one it is slow (5GHz). Rebot the TC and both are fast. The spot you are seeing it Internet2, which is VERY fast. No, it's the TC. I can run traceroutes simultaneously on two networks from the same TC and one will go fast along the same route while the other experiences multisecond ping times. Sometimes it gets to long (> 30 seconds) that TCP chokes.

    Ok.. that is so weird if the problem is not in the local environment, I cannot understand why a hold up.. 7 hops out can be affected by one wireless band and doesn't affect the other.. I have no mechanism to explain how that could happen.

     

    Can you post both tracroutes when it happens and show which is which..

     

    Also when you do one traceroute you need to turn off all activity from any other client in the network. So your own internal traffic is not affecting it.

    I rebooted the TC so I will have to wait for it to happen again. You're right, finding a mechanism that explains it is very difficult. It's not always 7 hops, it may be 5 or 6, just a short distance into Comcast's network. But a reboot of the TC ALWAYS fixes it.
