Hi all,

I bought this router on the strength of Amazon reviews and because it has SecureSpot.  I used to use the DSD-150 SecureSpot appliance, but it died, so it seemed a good time to do a router upgrade from my old g-network router.

I've got the DIR-655 installed, but unfortunately for me, it keeps rebooting unexpectedly.  I haven't figured out what triggers the reboots.  I have both wired and wireless computers in my home network.  When I got the router, I immediately upgraded the firmware to the latest (v1.32NA).  After a frustrating two days with this router, I tried downgrading to v1.31NA to see if it makes any difference.

I know how to use port forwarding, so I formerly tried inactivating the UPnP feature and the QoS feature -- still rebooting occasionally.  The reboots can come in a span of a few minutes, or it did go 14 hours (overnight) without rebooting.  Thoughts?

Uncheck DNS RELAY
Reboot all computers.

That will solve your problems.

Hi,

Return it as defective...do NOT tell them you upgraded the firmware.  Get a different unit and DO NOT upgrade to v1.3X firmware.

cc999:  I'll try and see if it helps.  At this point, it can't hurt, either.

SammyDad:  The beautiful thing about Amazon is their customer service.  I just sent a request for an exchange, and they're overnighting me another unit which I'll receive on Tuesday.  Gotta love Amazon for their customer service.  Prepaid return shipping label, too! 

When I get the replacement unit, I *won't* upgrade the firmware -- but I'm confused whether v1.21 (what it comes with) has or does not have SecureSpot, which is the reason I selected this router in the first place.  Seems as if there are two flavors of v1.21 firmware, where one of them has SecureSpot, and one doesn't.

Like anyone, I just want the stupid thing to work, period, with no fuss.  I should be able to put in my username/password (I'm on DSL) and a new network passkey, and that's about it.  Why, oh, why does it have to be this hard?  After all this time??

BTW, what does disabling the DNS Relay really do?  I read the support article, but, well, it didn't make much sense to me:  "When DNS Relay is enabled, the router plays the role of a DNS server. DNS requests sent to the router are forwarded to the ISP's DNS server. This provides a constant DNS address that LAN computers can use, even when the router obtains a different DNS server address from the ISP upon re-establishing the WAN connection. You should disable DNS relay if you implement a LAN-side DNS server as a virtual server."  In layman's terms, what does that mean to me?

Also, I did raise this problem to D-Link support tonight.  After telling the support tech what the problem was MULTIPLE TIMES, and what firmware version I was on MULTIPLE TIMES, he didn't really offer to change any settings at all.  Concluded it was defective, and said I ought to return it.  So there.

My router just rebooted...again.  Disabling the DNS Relay did not fix the problem.

My DIR-655 is SUPER sensative to my 2.4 cordless phone.  If the phone base is within 6 feet of the router it causes it to reboot constantly.  Switched to a 900 cordless phone and all is good.  Of the several cheap and old wireless routers I have lying around, none of them would reboot because of a wireless phone.  I spent days figuring this out with testing and trouble shooting.

I have H/W version A3..the best firmware i had was 1.21 (no securespot of nov/08'). No problems whatsoever then i took the plunge of 1.32na. big mistake! I just never had ne problems with any firmware so i thought i mine as well give it a shot with its fixes..to bad it made my router worse.

[famousdavis]

All,

I got a replacement DIR-655 for the one that kept rebooting.  But the replacement router unexpectedly reboots by itself, too!  It happened several times last night.

The router has v1.21, but I did have to reflash it in order to get the v1.21 that has SecureSpot.  No troubles doing that, and I had high expectations that with v1.21, I'd have no further trouble.

The router is physically sitting on top of my roll-top desk -- no electronics immediately next to it, but my server and desktop computer are underneath it.  I have a 5Ghz cordless telephone in my house -- does that interfere with the router?

I disabled UPnP, DNS Relay, and the QoS engine, but the router still reboots itself.

Any other thoughts on what I can do?  If it's not some environmental issue that exists within my home, then what setting is causing this thing to reboot?  Could my modem somehow cause the router to fail?  I wouldn't think so, but then again, I wouldn't expect a router to reboot like the DIR-655 has been.

Your thoughts?

[Sammydad1]

I have mine in Vertical Orientation as opposed to horizontal.  I also have my router plugged into a battery supported port of my battery backup device (UPS).

Hard to say if heat or voltage fluxuations are impacting your set up...but yah never know.

I think Sammydad1 is on the right track...

My first DIR-655 failed out of the box (sometimes functional like yours).  I was concerned about the high failure rate (of ALL brands of consumer wireless routers), but convinced that the DIR-655 was the best in it's class.

After scouring the web, I came to the conclusion that most, if not all, of the problems with the DIR-655 are due to a marginally-adequate A/C power adapter.  (Including, I suspect, the problems with 1.3x firmware - power marginal, add more features/processing, need more power, unit fails/hangs on peak power usage spikes....)

I RMA'd the first unit and decided if the replacement ever "failed" I would buy a 12v power adapter of 2.5 or more amps instead of the 2.0 amp unit it shipped with it.

Some laptops, netbooks, and LCD power adapters are 12v and of sufficient amperage.  Might be worth a shot trying an adapter with more amperage.  Make sure the polarity is the same and don't blame me if you plug in the wrong adapter and burn out/up the unit...

The voltage stability of the power supply is probably more important than the current capacity.  Many cheap brick power supplies will read the rated voltage with no load but then read significantly less voltage when a load is applied.

Agreed, the power supply needs to be well regulated. 

(I just realized I kept my old Desktop PC power supply when I upgraded it - it's got 12V @ 14A, and should be very well regulated.  Overkill, but I could probably rig it up to the DIR-655 if I have problems with it in the future to verify it is/isn't the power supply.)
