The wi-Fi on my router will just stop for no apparent reason. Any wired devices connected to the router still have internet access, but any wireless device will not even be able to see the SSID of my network. If I reboot the router, the wireless will come back, but later in the day it will go out again. I have the latest firmware. Any ideas on what could be wrong?

What Hardware version is your router? Look at sticker under router.
What Firmware version is currently loaded? Found on routers web page under status.

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.

What wireless modes are you using?
Try single mode G or mixed G and N?
What security mode are you using? Preferred security is WPA-Personal. WPA2/Auto TPIK and AES.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off Short GI, WLAN Partition and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

Some things to try:
Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can find these under Status/Device Info/Wan section.
Turn off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices on the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP.

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired PC while testing.

Hardware version is E3, firmware version is 5.10.
ISP is DSL, standalone modem. Not sure of the model - I am in Japan and the model name is in Japanese.
Wireless mode is mixed N, g and b but I will try and change it.
Security mode is WPA-personal, Tkip and aes.
Wireless devices include 2 laptops (Mac and windows), iPad,iPhone, iPod, apple tv, Sony tv, and a wii.
I do have a cordless phone, but it wasn't in use when the wifi went out.
I'll try some of your suggestions and will report back. Thanks for your help.

I was having the same problem with my newly-installed DIR-615 router's wireless service:  it would work fine for about a half a day, but then disappear (even the SSID was no longer visible), and an unplug-replug of the power to the DIR-615 got it back up and running.
Of course, that was not a good permanent solution, because that wouldn't be possible if I were not physically there in the room when the difficulty arose  
Here's something I found out that seems to be providing a permanent solution for me:
The instructions for the DIR-615 indicated that the "Channel Width" should be set to "Auto 20/40MHz" (available by going to: "Wireless Settings/Manual Wireless Network Setup").  Mine was set, instead, to "20MHz".  Resetting that to "Auto 20/40MHz" and allowing the router to reset itself did the trick for me (at least, it has survived longer than ever before and has not yet lost the wireless service and the SSID has not disappeared...).  The other settings on that page were OK as they were set by default for me:  "Enable Auto Channel Scan" was checked; "Visibility Status" radio-button was selected.
Hope this helps someone else!!

To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.
