Switched to G-only yesterday afternoon and have had no issues since. Streamed a show on Hulu from another room; perfect performance. Keeping my fingers crossed. Will try channel switching, also, if I have any more trouble. Am still going to give N a try. Thanks for steering me in what looks like the right direction.

[FurryNutz]

Good to hear. Let us know how N only and Mixed N and G work out for you. If there are other WiFi in the area and your router is somewhat close to your devices, you could also try lowering the power output of the WiFi and see if that will help. I would try this last a last resort though. Hope it works well.

Probably going to jinx myself, but I may have found a fix. I tried everything from changing modes to messing with QoS and security settings. Since this happened every 24 hours like clockwork, I looked into the enable schedule. It's set by default to always. I thought there may be something wrong with their schedule. So, i created a new scheduled and called it Really Everything. Checked all days and all hours. Set wifi enabled to that schedule and am currently enjoying a record 3 days uptime. Can anyone verify?

Same problem here.  I'm running two routers both HW ver A4 and FW ver 1.35NA.  the primary is providing the routing capabilities throughout the house and is tied to a 24 port Cisco switch. It maintains a wireless network covering the upstairs of the house.  The second hangs off the switch and acts as an access point providing wireless coverage for the first floor.  When I started having this problem, I first noticed it with my iPhone and other portable devices and attributed it to them, then computers started having the problem so after logging the times of the errors, attributed it to "peak" hours and thought it was interference from other networks in the neighborhood (I can pull 9 from my living room).

After playing with different channels and settings I actually observed the WiFi light on the front of my router was shutting off.  A few minutes later, it would come back on.  If I unplugged it for several minutes it would work for a while, if I unplugged it and plugged it right back in, it would continue cycling on and off.  After reading through this forum, I got to thinking that it was the overheating problem with the wireless circuitry brought on by heavier use (I tell my kids to keep their computers plugged into the Ethernet ports when they're in their rooms). So I reset the primary router just before typing this and changed the TX power down to medium.... it had been on and off all evening and has remained solid since I changed the power.

I'll keep you all posted, but if this works, it's the relief of a symptom, not a cure.  If tech support is listening, I'm betting the end result is that it's bad engineering and the wireless subsystem is overheating.  No amount of tweaking settings or a firmware upgrade will really cure the problem.  If D-Link is going to stand behind this one, it will be to replace the bad units with better hardware.  But, I could be wrong.

I'll leave the systems running with one on full power and one on medium power for a couple days and see what happens and post the logs if there's anything interesting.

Your issues may not be HW related, you need to fully troubleshoot your system to see if your settings and your system is set up correctly. I have basically the same setup on at my house and do not see the issues you are describing.

It would help everyone here in the forums if you could give us more detailed information on how your system is set up and how it's configured so we can try and help you out:

What wireless modes are you using? Have you tired different modes? Single and mixed? What are those results?
What devices are connected to what router? Device versions?
Both Wired and wireless?

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

There are many other factors that play a part in WiFi and these routers and can effect them. You have to troubleshoot has much as possible to help narrow down the root cause. I grant you that there maybe some HW issues out there, however most issues stem from user configurations and or other items up stream or down stream from the router.

When set to G-only I had no problems over a 36 hour period. Tried setting it to G and N and it stopped broadcasting within 3 hours. Tried setting the channel to 11; still stopped broadcasting within 3-6 hours. Tried setting it to N-only, but all my devices can't handle the encryption with N. So I'm back to broadcasting only in G.

Update: Since setting the router to G-only I have had no problems for over a week. Working flawlessly. I haven't tried N-only because some of my devices don't receive in N. Would like to use the mixed N/G mode, but the unit stops broadcasting on that setting. Very pleased with the performance on G-only.

Would you care to explain how any of the issues you listed would stop the hardware from broadcasting completely? We're not talking about channel interference or random drops. The entire SSID disappears and the hardware flat out stop broadcasting anything. I got my wifi signal analyzer out of the toolkit that I use often to map wifi hotspots and channel layouts. The router is not broadcasting a signal at all.

To update my situation, 4 days without loss of signal since changing the schedule.

I have 1 server wired to a Cisco 2950 rackmount managed switch. The switch is ran off a Cisco 3600 rackmount router with ADSL wic. The DIR-655 is also plugged into the switch on a separate vlan. 1 pc is plugged into the DIR-655. PC and server always run fine. On the wifi, I have a netbook, 2 laptops, 2 Android cell phones, HDI dune media streamer, roku xds, and a Wii.

I've tried all modes from only G to only N and all mixed in between. My old Buffalo G running Open-wrt has always worked 100% flawlessly. I have 4 DECT 6.0 handsets operating in the 1920-1930 MHZ range, well outside of the 2.4ghz that this router uses. Dlink is using WPA/WPA2-personal with AES encryption. There are many routers in the area, all operating on channel 6 and 11. Currently, I'm on channel 3.

Moral of the story, there is no interference or user error. This model B1 with 2.00NA firmware just flat out stops broadcasting any signal whatsoever.

Could be an issue with the internal radio, give tech support a call and maybe they can see whether you need to RMA it.

[FurryNutz]

I agree, if your wired connections are working and the wireless isn't, then possible issue with the radio HW.

[leatherneckbiker]

I agree, if your wired connections are working and the wireless isn't, then possible issue with the radio HW.

Like I said in my original post and as was pointed out by Cexshun... What devices I have connected and what settings are on those devices have absolutely no impact whatsoever on the router itself shutting off the WiFi while maintaining the rest of the network.  4 pages into this forum and seeing what everyone else has written and what your responses have been it seems obvious that you are grasping at straws. If you are D-Link tech support, then admit there is a problem and say you are working on it or say you don't know.  That is more helpful to the people in this forum than sending them on wild settings chases.  A fix could be broadcasting in G only?  Really?  If I purchase a car that has air conditioning and a radio and I can only use one at a time, the mechanic isn't going to tell me that I need to turn my radio on AM and drive in reverse to get my car to work, he's going to acknowledge that something is wrong with the car and fix it.

Indicating that the wireless indicator on the front of the router itself is turning on and off and seeing the SSID come and go with a sniffer in perfect synchronization with the LED is all the troubleshooting any intelligent technician needs... especially when I can observe this behavior with no wireless clients connected!

Now, to update, the primary router has run correctly since reducing the power output of the wireless signal from high to medium.  The second router acting as the access point has remained on high and has continued to cycle on and off. So again, if this is a "fix" then I am using a corvette that only stays running if I drive it under 45... not really a fix. I have not tried resetting the schedule yet.  I will do so and post the results.

[FurryNutz]

The information I recommended are steps in troubleshooting your issue in hopes they might help narrow down the issue you seem to be having. If your unwilling to try them out then thats your decision and I'll recommend others here can try and help if you. If not then I would suggest you give Dlink a call and talk to them of this issue. Were only here to help each other out as much as we can. It's up to people to listen and take action on the information presented. Have a great weekend.

Hi all, first post here. I just recently started having this problem as well. I have owned my 655 for a few months, but now every 4 hrs or so I have to reboot it to get my wifi back. The wired works fine, but not the wifi. This is very, very annoying as I work from home a lot and I am now running ugly CAT5 along the floor into my office since I cannot reliably stay connected via my 655.

I have tried everything in this thread and nothing seems to work. Has D-Link weighed in at all with this? This is disappointing as I normally don't mind Dlink for SOHO gear. In fact I have a Dlink boxeebox, router, and was thinking of getting their entry level NAS enclosure ( 323 I believe) to augment my other network storage devices. However I am quickly now getting turned off of Dlink all together.

I have moved recently and that does coincide with the start of these outages. I have ran inSSIDer and there were plenty of networks around me but not a one of them was using the same channel.

I have recently upgraded to Rogers 25 Mbps service which forces you to get their SMC router/cable modem device. I did have to have them remotely disable the built in router as I already have my home network hanging off the 655 and all the IP's setup nicely--the SMC uses the same default subnet as the Dlink, so there was a conflict initially. Since Rogers has turned that off I only see my Dlink when I access the default IP of 192.168.0.1.  So I doubt it's that, I'm just trying to pain a clear picture here.

As much as I don't want to, I'm pretty close to just going out and getting the next most popular Netgear router.

[davevt31]

This is pretty much a user to user forum so you won't see much "Official" information here.  Best to give tech support a call and see what they can do for you.

Hi dmaker,

Part of the problem is the lack of Tech Support here.

However, sometimes a reboot of the router doesn't cut, having gone through the same problem, I have the experience necessary to tell you exactly what to do. The Router stays on all the time, whether you are there or not and can a momentarily power outage or voltage spike, which can scramble the settings that you can't see.

Do a Factory Reset by holding in the button in the back of the Router for about 20 to 30 seconds and release the button with the power on. The lights will go out and come back on.

If you backed up the settings, when you didn't have the problem, good, you can restore them via the backup. Otherwise, you need to reenter all settings by hand.

After you reenter all settings by hand, now would be a good time to back them up.

Also, you should have the logs Emailed to you. Purpose: When the logs are Emailed almost constantly, because the logs get full, is the indicator that a Factory Reset is required again, or the Router is going out, if a Factory Reset doesn't correct the problem.

[dmaker]

Thanks for the tip creator. I have done a factory reset and it's been up now for a couple of days. Working from home today ans so far so good. When I was working from home on Wednesday, it dropped twice by this time already.

Fingers crossed...
