Airport Network Not Recognizing A Time Capsule Hard Drive.

Symptom:
The Airport Network is not finding a Time Capsule Disk.


Possible Cause:
The base station is misconfigured, or corrupt.


Possible Cure:
Reset the Base Station, Softly:
Reset the Base Station, Brutally.


Reconfigure the darn thing.



1.) To reset the Base Station [either way], follow Apple’s instructions Here.  [<- Click]
A good article describing the location of the reset button for your model, how to perform a soft or hard reset, and what the ramifications of the said reset would be.


2.) Assuming the above didn’t work; Please deposit twenty-five cents for the next half-hour.

IF; The base station is the only wireless access point:
The Airport Utility located in  /Applications/Utilities  may ask you to restore your previous base station settings. Click ‘Restore’ to automatically re-enter those settings; after the base station reboots, try the wireless connection again. If all else fails, reconfigure the base station from scratch.


IF; The base station is part of a network (multiple router / gateways):
Consider these potential issues;


• A newer “dual-band” base station has two ‘networks', one for older [WiFi B, and WiFi G (faster) access], and a separate one for newer [WiFi N (even faster, and with greater distance potential) access].
If older (non-N) devices aren’t a consideration, then the router / gateway placement isn’t a problem. However, if older devices which can only connect to older (B, or G) networks are present, they can slow the entire network down to B or G speeds.

The more networks present, especially for B and G networks [neighbours, and possibly other devices such as wireless phones, or microwaves], the greater the chance of conflict [11 channels or frequencies available; N networks have 149], resulting in slower speeds, and / or connectivity issues.

 The environment plays a part in the distance of a network; distances are quoted as "line-of-sight" [unobstructed]; variations such as buildings [their construction; vent work location, steel surroundings, wiring placement], and airwave congestion may restrict the access to a network.

Current Comcast / Xfinity ‘Dory’ gateways [SMCD3GNV] cannot have their wireless network deactivated and, as such, always occupy a frequency.


That being read, you may need to consider the placement of the routers / gateways to compliment one another without conflict.

Do you wish to extend the network, like a Wireless Distribution System (WDS)? Several links to help configuring exist for different configurations:

Avatron Air Display driver issue under Mac OSX: Lion.


As mentioned at the bottom of the Avatron site

The Air Display host software runs well on Lion, but has this limitation: the built-in video driver on certain 2008 and 2009 Macs is incompatible with third-party video drivers. You can still install the Air Display host software, but until Apple fixes the issue, the Air Display drivers will disable themselves on Lion on these specific machines.
Affected machines include:
  • 13" MacBook (aluminum late 2008, early, mid, and late 2009)
  • 13" MacBook Air (late 2008, mid 2009)
  • 13" MacBook Pro (mid 2009)
  • 15" MacBook Pro (late 2008, 2.53 GHz mid 2009, mid 2009)
  • 17" MacBook Pro (early and mid 2009).
  • 20" iMac (early or mid 2009)
  • 24" iMac (early 2009)
  • 21.5" iMac (late 2009)
  • Mac mini (early or late 2009, Server late 2009)
  • Mac mini Mac OS X Server (late 2009)
Apple is aware of the bug. We are hopeful that they will release a fix soon.
