When I first got my DIR-655 (Hardware version B1) the Wireless would keep on turning itself off, and it needed a reboot of the unit to turn it back on again.

After having upgraded to the 2.03NA version of the Firmware it seems to be working correctly and hasn't turned off for a few days now.

Good to hear.
Some other things you can 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.
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.
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP.

Try single mode G or mixed G and N?
What security mode are you using? WEP, WPA or WPA2? Preferred is WPA-Personal. WPA2/Auto TPIK and AES.

What is OS of your wireless computers??
Have you tried to change the wireless channel of the router....

[tnunan]

I'm using Windows 7, but the radio was definitely turned off.

The signal vanished from Inssider and my Ipod search function as well.

[FurryNutz]

Any cordless house phones?
Any other WiFi routers in the area?

[tnunan]

It was not an interference issue, the wifi radio just turned itself off, dead, gone, like the parrot.

Upgrading the firmware fixed it, it has been stable since then.

[FurryNutz]

Good to hear you got it fixed. Odd that it was not working.
Suggestion for running WiFi: Try single mode G or mixed G and N?
Preferred security is WPA-Personal. WPA2/Auto TPIK and AES.


Enjoy.

I am having the same problem as the OP. It seems that every night when I get home from work I need to reset my DIR-655 to get the wireless working. The lights on the unit do not indicate an issue but none of my wireless devices pick up a signal. After resetting everything works fine and the next morning it is still working. Later at night I have the same issue again and today I lost the connection sometime during the afternoon while I was out. I have firmware version 2.00NA but when I do a firmware search from the router it says I have the most recent firmware version so I don't have the option of updating to correct my issue as the OP did. The only thing I should I mention is that everything worked fine for about a month and then once I installed a Canon WiFi printer last week this issue started happening. I don't know if it's coincidence or related. Can someone help me with this?

Thanks

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? WEP, WPA or WPA2? Preferred 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?

Ensure DNS IP addresses are being filled in under Setup/Internet/Manual?
Turn off QoS options.
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.
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP.

Let us know.

I have comcast cable and a stand alone Motorola SB6121. I have my D Link router set for mixed G and N. I'm using WPA2 for security with a passphrase. I have about 8 devices on my home network but only 2-4 are connected at once at any given time. I do have cordless phones that run at 2.4 ghz. With my old setup I would lose wireless signal whenever a call was placed or received to our home phone but then it would reconnect after the call was done. I say old setup because I've only been with Comcast for about a month and the router was purchased when I switched providers. I can see other routers in the area when I do a search for signal.

I looked at most of those settings recommendations earlier and the only one that wasn't set according to what you recommend was DHCP reserved IP addresses. I saw the option on my router where it lists devices that have connected and gives me the option to reserve the IP address. I haven't actually gone through that yet but it would seem strange to me if that one setting was causing this issue but then again I'm new to cable and to D Link. I'll double check that firewall setting because I'm not sure on that one.

Why don't I have the option to update firmware? I assume I don't have the most recent firmware of the OP upgraded. I have exactly the same problem that he did.

Thanks in advance for the help. I really appreciate it.

House cordless phones running at the same 2.4Ghz frequencies will impact the operation of the routers wireless.
Updating FW wont fix this as this is just happens you have phones that run the same frequencies.

Can you test the router out with turning off ALL cordless phones and wireless devices for a test and see if the router exhibits cutting out? Wondering if it's encountering interference issues.

For updating FW please review the FW update sticky and get FW update files directly from the DLink web site. Don't use the updater on the router.

Test this out first if you can. I'm running B1 and v2.00 FW and my unit is running great.

The signal loss is very random and happens once a day and then is good for close to another 24 hours after a reset. I only have 3 wireless devices active right now and everything is fine as it has been since I got home this afternoon and unplugged/plugged in the router. I just tried to use my cordless phone while on the internet and had no problems whatsoever.

Unfortunately I have no way to recreate the cutout issue in order to figure out what the cause is. The only thing I know is that it never happened until I connected a wifi printer. I don't know if that could be causing a problem but I would hope not as a wifi printer is a pretty common device to have in a home network.

[FurryNutz]

Yes they are common items to have on a wireless network. I would turn it off and test to see if it the symptoms goes away.

Also you can try turning off security on the Wireless to test and see if anything changes. Try Using single mode G for a while and test.

Try some of the suggestions mentioned.

Any other WiFi routers in the area? Use InSSIDer application to see whos around you.

If any of this doesn't work, by all means update FW and see how it goes.

Keep us posted. Maybe some can review your router settings with you using teamviewer.

I'm sitting in front of my router now and was going through your recommended settings one by one to ensure I didn't miss anything and I did come across something. Under setup and manual internet connection I'm looking at the section at the bottom of the page with the header "DYNAMIC IP (DHCP) INTERNET CONNECTION TYPE". I'm noticing that the Primary and Secondary DNS address are both 0.0.0.0. In your settings are these the ones that you said should have something in them? If yes what is it suppose to be and could this be the cause of my issue? I ask if it could be the cause because I don't want to break anything else by changing a setting.

Also, is it weird that one I first log into my router that the date and time are wrong? Not sure where to change it?

[FurryNutz]

You can fill those in using the DNS addresses under Status/Device Info/Wan Section however are not usually needed. They can be filled in manually. Copy and paste them in.

You can change the date and time using Tools/Time. Set your time zone then enable NTP server using time.nist.gov.
