My new 2tb time capsule becomes undiscoverable after a few hours, any help?

Question

I just purchased a new 2TB TC this past weekend.  I plugged it in, and have wirelessly hooked up two imacs, a macbook pro, and an apple tv to it.  It is hooked directly to my modem and has replaced my previous router.  The problem I am having is that after about a day, none of the computers can discover it via airport utility or on the network tab.  Any suggestions, because it is really getting annoying having to restart it every morning etc.  How do I make it recognized 24/7?  Thanks!

What if we cannot limit to 5 GHz n network only. I have a cell phone that only will use 2.4 ghz network.
Try this.
Open the manual setup of the TC
Disable the Guest Network if not needed.
Give the 5GHz network a separate name. (even when not needed)
Switch the radio modus of the wireless to "802.11n only (5GHz) - 802.11b/g"
You will reach this option by clicking the drop down menu while holding the option key (alt)
After that, force the supporting station(s) (MacBook Air in your case) to use the 5GHz network name only and connect the smartphone to the 802.11g.
Delete the 2.4GHz network from the list of the "known networks" in the System Settings of the MBAir while the wireless of the Air is switched to OFF
Eventually check the following to optimize your wireless infrastructure. That will ease the things too.
General radio problems in wireless networks based on disturbance from interferences, obstacles in or reflections of the radio beam
The radio beams of a wireless are not Roentgen X-Ray based and therefore obstacles, interferences from other wireless systems or reflections of the radio beam could cause major disturbance of the wireless network and based on this, the data stream in the network.
Possible reasons of wireless problems:
Obstacles like Walls, magnetic fields from live high voltage lines, antenna cable or insufficient shielded speaker systems. Metal frames or plating, furniture, bundled water pipes, dry construction plaster walls*, Humans* and much more.
Interferences from other radio equipment like Bluetooth, cordless phones, neighborhood WiFi, cordless speakers, cordless doorbells, intercoms, ptt units, baby phone's, surveillance and alarm systems, commercial weather radar, some military equipment and so on.
*) Water is a big bar for radio. Plastered dry construction walls and Humans contain a lot of water.
One of the above named possible reasons or any combination can cause major annoyance due to unwanted network traffic or packet collisions and could at last force stations to disassociate from the network or get disassociated by access point (router) due to time out or signal loss.
User experience: Heavy fading signal strength, slow and sluggish wireless connection iTunes/Video stream drop, lousy data transfer speed, total connection loss or only time relating disturbances here and there.
Possible Solutions:
Placement of transmitter. Not flat at the wall. Not in a corner, not on the floor, not behind a furniture, not near of other radio sources e.g. cordless phones. Not near of anything that can reflect radio beams. Best: as high as possible; e.g. Airport Extreme mount on ceiling. Maximum possible line of sight to all stations respectively corners of the home.
Placement of stations: as obvious
Placement of yourself: If possible not between your Mac' antenna(s) and the transmitter.
Radio interferences: Check that the channel you use have at least a 5 channel gap to the two strongest wireless networks around. If possible use the recommended overlapping free channels for your country for best performance. On 2.4GHz networks -> for US-1,6,11 and for Europe 1,5,9,13. If possible swap to 5GHz 802.11n only and force the stations supporting this to use only 5GHz. Disable 802,11a/b/g wireless if possible. Place cordless phone stations as far away from the router (access point) as possible. Eventually disable all radio transmitting equipment in the house. If the wireless then work better, enable one at the time to see which is the disturbing one. Don't forget leaking microwave ovens. A running faulty microwave may drown your complete wireless network at once and your neighbors WiFi too.
