The Symptom:  Wireless works very well for most of an evening or day (most things connect at 65Mbit, and I'm getting between 20 and 40Mbit to the fastest Speakeasy sites from the wireless clients), then for reasons unknown, the wireless presence simply disappears.  All devices on wireless are disconnected, and wireless scanning from portable devices (HTC Evo's using WiFi Buddy, and Windows netbooks using InSSIDer) shows that the Wireless router has gone offline.  Power-cycling the DIR-655 brings wireless back, but only until the next cycle of the same symptom.

 I have a visible SSID, no guest network, and 20MHz channel width.  Security is enabled in WPA/WPA2 mode.  Firmware reports the latest version.

I *am* in an apartment complex, so the airwaves are pretty cluttered.

Wired Equipment: 
 - D-Link DIR-655 Router (Mixed BGN mode, WPA/WPA2 security, 20MHz width, fixed channel 2/auto (seems not to matter), One 7Db external dipole, and two original onboard antennas)
 - Zoom DOCSIS 3.0 Cable modem
 - Sprint AirRave

Wireless Equipment:
 - Intellinet 524704 Wireless 150N Access Point, Station Infrastructure mode. (7Dbi external antenna. This is wired to a Zonet 8-port switch, which is, in turn, connected to my LG Integrated Home Theater unit)
 - Toshiba NB305 netbook
 - Dell of indeterminate, but recent model
 - XBox 360
 - (2) HTC Evo's
 - Canon Pixma 560MP wireless printer/scanner
 - Ipod Touch


Any ideas?

Hi mjcecil,

Instead of locking to 20Mhz go Auto 20 /40 Mhz.

Also don't Enable Auto Channel Scan, experiment around and find one that works for you.

Why change the Antenna?

thecreator:

Antenna change was merely for signal gain.  The router is downstairs, and the AP/bridge is upstairs.  Seems like the higher-gain antennae were called for.  Is there a reason I *wouldn't* want to change the default antennae?  (I do admit I take a simplistic view of all of this radio business)

Using InSSIDer, I was able to determine that the least used channel in the complex is 2, which is what I bound to.  However, your point is well taken in that, just because it's not used does not mean it's necessarily clear or effective for WiFi traffic.  I'll poke around with those some more.

Thanks,

Mark

I have exactly the same problem. DIR-655 Rev B

Works great, then wireless disapears. Disabling then reenabling the wireless will also reset it.

Has anyone resolved this?

Thanks!

The problem may be nearby Wireless Devices that are on the same frequency causing problems with the Wireless portion of the Router. Try a different Channel.

What does your log say?  In order for the knowledgable folk in the forum to help you, they need information.

Unchecking "extra wireless protection," along with a near empty channel may help your plight.

Need more info.

Check the power supply and the wall outlet for brownouts.  This kind of thing can happen when an appliance on the same power circuit kicks on.

Switched to 20/40 mhz

Wireless has been up for a week! Yay!

Thanks!
