Over the past week there has been countless people having a problem with the 5.5.3 airport update and is searchable on these forums, but said that, the procedure that seems to work for some people is to disconnect you modem from the power source, your router from it's power source and shut your computer(s) down for an hour or two, then in the same procedure (giving your modem time to warm up) plug and turn everything on.
Hope this helps.
Hi I have exactly the same problem as daveevan1 – my airport shows full signal but every 10min or so I have to restart the airport because the connection is dropped (although the airport still shows full signal)
I tried your solution of disconnecting computer/router/modem for a few hours and it helped for about 24h – now the problem has returned, same as before.
this started because of the Airport 5.5.3 update – is there any way of downgrading? or any solution for that matter.
I've been having alot of problems with this update. I got the update 6/19 and the same day I lost connection to my time capsule. The WiFi works through the TC, but my macbook doesn't recognize the TC neither thru AU or direct ethernet cable. I took everything in to the store & the genius got it working. This lasted a day. After deleting all my past & current network connections, I rebooted and got the back-up working again. That lasted a day as well and so 2 days ago Apple gave me a new time capsule. I was able to do the initial back-up via ethernet, yet I can no longer access the TC after numerous tries of shutting down, etc. Can we reverse back to the previous version before this update?
I too have been blighted by the airport Utility upgrade to 5.5.3 my network has not been stable since I loaded this about a month ago. I've been following numerous blogs on the issue and the majority recommend rebooting the entire network, which works however this can't be the final state... I'm just wondering why there hasn't been an official notice from apple in relation to this issue. Is this because the change is some how related to the development of iCloud.. having been a devoted Mac users for 17 years.. this is the first major issue which is persisting and I'm not impressed by the silence from Apple inc.
I have reverted to Aiport Utility 5.4.2 and the issue has gone.
