Hi people, I thought I would try this before I return this router like the previous one. I have h/w A4 with f/w 1.21 came like that off the shelf.
My NIC on the mobo is a realtek pci gigabit RTL8110SC(L). and OS is win xp pro sp3. Im also on dsl with modem - 4200 speedstream which I cannot access.
So i am wired to the router from my desktop and randomly the connection will drop and pick up again. This NEVER happened with the old router I was using (dlink DI-614+) and still works.
I have turned the dns relay off and manually assigned open dns, it seems to have sped things up a bit and slighty reduce the amount of disconnects, but it still happens ( a pain when playing css or dl big drivers)
The #1 lan port light will go off for a sec or 2 and come back on. Also it is picked up in event viewer as event 4201
"The system detected that network adapter \DEVICE\TCPIP_{F8D30E19-3ABE-4B45-BA06-F4B97DEC044E} was connected to the network, and has initiated normal operation over the network adapter.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp."
This is the same id as when the pc starts. I am wondering if there is any realtek HW in the router that may cause this, or FW or other?
I had a dir-655 about 3 months ago also, I think it was an A3 with 1.20 or earlier firmware and did it way more often so I had to return it.
The disconnects rarely last more than 5 seconds, but thats an eternity in css :D
Any suggestions/help would be appreciated. Thanks.

- Latest NIC driver installed?
- Try setting WAN speed detection to 100 manually instead of Auto on the router, and set the same with your NIC driver in your OS.

A3 router has Realtek Gig chipset for the gig switch ports. All my gig cards are Realtek also. Yeah go to the Realtek site and grab the latest drivers for the NICs. I set all of them to 1GB full. Then go into a another external gig switch. I had managed to get this max out though... on XP Pro SP3

I still have the DNS Relay enabled but you need this feature since is forward the DNS Client & DNS Server. The bug in 1.20 and up firmware has the issue.

Thanks EddieZ. Updated the driver and SEEMS to be fine now. Strange thing is though, the date on the old and new driver are the same lol I think version # jumped up a .0001 though. Realtek never seemed to have the same stability as marvel has for me anyway.
Thanks again

To be honest: Realtek NIC s**k. :o

Marvel Yukon!!!! for the win.

Well the A3 hardware uses Realtek chipset for gig switch. I know that A4 uses a different chipset. I think the Realtek have been very quick I use their drivers for my Gig Rigs and wireless N cards.

Gig PCI you can raise the FBS to 173MHz to overclock the cards if you needed. I don't my speeds are great! Can say the same for the other chipsets.

Some nuance here: Realtek switches are OK, the NIC though do not have the same performance as Intel Gigabit or Marvell chipset.

If we're talking Switch chipsets, Vitesse. ;D

Wasn't that in A1, A2, with 96KB switch packet memory buffer, then dropped in A3, A4 uses what? FCC photo's were fuzzy on A4 PCB. One of the 8-port gig switch uses Vitesse 144KB packet buffer as well as the DLINK gig switches for the home. Realtek uses 832-838KB packet buffers on that chipset in A3.
-
packet buffer doesn't always mean speed. The Vitesse chip out performs the realtek everytime.
-
I've got an A2 ;D ;D ;D ;D
More packet buffer can compensate for lack of speed. Perception-wise...

Offtopic: do you know when Dlink starts selling those ANT24-0230 (http://www.dlink.com/products/?pid=545) in Europe? I will pay quadruple when ordering from Europe...I'm a good guy, but the Mrs will kill me
-
A1 and A2 uses Vitesse, A3 and A4 Realtek, right?

to be insane you need 1500 posts
godlike is 750
no idea, it may not be a EU product. I can ask.
-
I'll settle for Godlike :)
It's a terrible waste they don't sell it in Europe. Got a rely from Dlink support and the answer to the questions "Will it be sold in Europe and if not: why not?" was "This item is currently not sold in Europe". As if I didn't know that ... :o

yea, super informative.
I'll look in to it for you.

Nice! If you get a clear answer you're Da Shizzle BAM Bizzle (for normal people: The greatest thing since sliced bread). Nice additions to my vocabulary :D

i'm bumping this as this is exactly what is happening to me.
i have a gigabit realtek chipset as well.
i have a 655 rev. 2
randomly, i get "a network cable is unplugged" messages from the router. i don't know if the router is just disconnecting or if the router is rebooting or what.
my 655 has been pretty solid until a couple weeks ago, which is interesting, because this post was originally made back on 1/29.
i believe there was a new realtek driver that was sent out recently, but the driver for the card shouldn't make a difference. i connected my nic up to an older dlink 10/100 router i had and no problems at all. so maybe there is an issue with the 655 over gigabit?
i've searched on these forums and on dslreports. there are a few reports of the same issue happening. any idea what's causing this on the 655?

Whats changed in the wireless environment?
-
What progress is made on the next firmware update? I can't even use my wireless N but the USB sharepoint works 100%.

Whats changed in the wireless environment?
nada. wireless is on though.
i've tried 3 different firmwares now. all on straight up default settings. i'll get disconnects.
restore settings. still disconnects.
clean firmware and re-create settings, still disconnects.
i'm on the most recent beta that was posted here, dated as 1/24/2009, ver 1.21. all default settings. i'm logging on the router right now. the thing is, the disconnects are so random, who knows when it will drop again. sometimes it will come in bursts - will disconnect 2-3 times within a matter of 2-3 mins or so. other times it will just disconnect once after hours of normal, steady use. seems to happen mostly though when i try to access a website.
i'm on the latest realtek driver, version 5709 i think. i think it's this latest realtek driver, but i have no problems connecting at 10/100 on another d-link router. haven't tried forcing to 10/100, but what's the point on a gigabit switch and when all my other equipment is gigabit? i could try rolling back driver to early version i guess...
-
if you disable the wireless does this behavior stop?

thanks for the follow-ups lycan.
since i reported this earlier, and have the logging completely on, so far no disconnects. having logging on is the magic bullet so far...
and it's not the router rebooting. shows uptime of 4+ days. i'll report back later...
-
well, it disconnected again around 5:45EST. i disabled the wireless as you suggested and so far no disconnects and it's been about 3 hours. i'll keep the wireless disabled for the rest of the evening and if all is well, i'll re-enable tomorrow morning.
even when i had the wireless on, i had it running w/o encryption and the disconnects were present.
-
back with my daily report...
wireless off the past 24 hours or so. not one disconnect.
i noticed that there a a few topics now here with complaints about the same thing. something must be going on with this thing...
i'll leave wireless off until later tonight then turn back on for tomorrow. if it disconnects, then we know it's the wireless aaaand, if that's the case, what's the next course of action? any advice?
-
ok, back again - to reiterate, i have a 655 A2
I've pretty much narrowed down the issue to my NIC. it's a realtek gigabit RTL8169/8110 chipset.
i believe there is an issue with their driver newer drivers, versions 5709+. i'm not sure what the driver version was before that. there is a new driver realtek just put out in the last week, 5712, which i was hoping would fix the issue, but it does not.
on the 655, i've tried several settings. wireless on/off, etc etc etc. it will still disconnects on the lan side randomly.
i plugged into the embedded 10/100/1000 Intel NIC i have on my motherboard (for w/e reason, the 655 will never recognize it as a gigabit nic and always connects as 100mbs), and i have left it like that for over a week now and not one disconnect. if i go back to the realtek card, it connects at gigabit, but the random disconnects return.
i know the nic isn't bad because i tried using an old dlink di-604 i had sitting in the closet and it connects @ 100mbs and was solid for over 2 days straight on the realeak card.
i have not tried the realtek nic in 100mbs mode on the 655, but all my other equipment is gigabit, so no point to try that for me since i know it works in 100mbs on a different router just fine. hopefully dlink will find what the issue is with these newer realtek drivers and fix it.
in the mean time, i'm ordering a zyxel x550N router with gigabit switch to see if it's simply just the realtek drivers or if it's the actual router. i'll report back after testing. should be sometime later next week.

It could be the router PCB or the firmware. I use external switches to the DIR-655
dir-655 ---100mbps switch (streaming media boxes and wireless access points)
dir-655 ---1000mbps switch (all 4 systems uses Realtek Gig NICs)
-
i only need 4 ports - no reason to go and buy extra switches.
and it has been very reliable for over a year, and then the new realtek driver came out (5709+) and that's when i've been having issues i think.
so since then, i updated the firmware from 1.11 to the newer 1.21 firmwares, and no matter the firmware, they all had disconnects.
it's possible that the pcb has gone bad, but not likely. i have other machines connected at 1gbs just fine with no disconnects. this appears to only happen on my realtek gigabit nic.
the OP on this thread sounds like has same exact issue as me and many other people with some similiar sounding issues.
-
Well the only reason why I use external switches is offload the router switch into external switch better throughput. But you can use old router and disable the DHCP on it to use an external switch. Once these routers only had the WAN port and 1 LAN port then you had to get external switch to extend your network. Today you got 4 ports switch right on top of the ANTs.
If you keep on getting drop outs from the LAN to LAN then the router is faulty. But you need to do some other testing like get external gig switch. Don't you have 54 and 100mbps running as well?
