Furry, D-Link router software only offers FW 1.21, where is a later FW to be found?

Ok, well, you could update and see if that helps. Just know that you cant downgrade back to v1.21 after.

Please provide directions to have someone review router settings.

Download the program. Run the program and select RUN if you don't want to install it. It's a self contained running program that you don't have to install. IT will run by itself. Send me the Remote USER ID and Password via PM on here if you want me to have a look. I will connect to your desktop and we'll go from there. Please be wired to the router for this review.

Update:  I tried the suggestion to disable IPv6 on the Windows 7 and Vista machines.  Did not have any impact on losing wireless connections.  I've already tried to go back to FW 2.07 and that also did not have any impact.  Same results no matter what I do!

I just lost wireless connection at 10:52AM ET on the XP, 7, and Vista machines AT THE SAME TIME.  I checked the modem and it was still up and running for over a day, so this was the DIR-655 router that dropped wireless.  Nothing was contained in the router log.  It simply stopped broadcasting the wireless signal!

Yesterday, I lost connection three times during the day (XP, 7, and Vista machines AT THE SAME TIME).  Nothing was contained in the router log.  It simply stopped broadcasting the wireless signal!

Am I to conclude this DIR-655 D-Link Router is simply garbage?

Hi,

Well I don't think it's a Dlink - Router problem, this issue can happened with any router brand IMHO.

I experience the same problem (WAN drops only not LAN) when generating high traffic like playing online (Ie: World of Warcraft) or doing intensive web site request. I'm still investigating.

For myself, I observe a "1014 DNS Client Event: Name resolution for the name xxx timed out after none of the configured DNS servers responded." in the windows event log.  You can see in Control panel\Administration\Event viewer\System if the connection drop is following a 1014 DNS Client Event.

Here what causes i'm investigating so far:

  -  TCP/IP Offload is enabled for a network adapter
  -  TCP/IP v6 is enabled and ISP's does not yet support TCP/IP v6.
  -  The spanning tree “portfast" setting is not enabled on your servers switch ports.
  -  Router and PC communicating on different channel or standard.

See link: http://social.technet.microsoft.com/wiki/contents/articles/3336.event-id-1014-microsoft-windows-dns-client.aspx for further reading and trying.

Question to Furry:

I'm curious about the first potential cause mentioned above which is the TCP Offload. I know that the DWA-552 does not support TCP Offload, but the fact it is enabled by defaults in Windows 7 / Vista, can this have an effect on the present issue?

Thanks

Thank you for posting the good information.

We've found by experience on here with users that most of the wireless problems dealing with improper operation and sporadic connections with WiFi is usually having to deal with more than a few other neighboring WiFi routers near by using up all the channels and AUTOSCAN and the programming behind it, has to stop and try to find another usable channel. This seems to find one for a time, however even at some point, even if the channel is used by another router at a longer distance, the channel is still being used and there is interference on the channel. So again the AUTOSCAN function kicks in and stops the connections. All this seems to be happening on the 2.4Ghz frequency as more and more people acquire WiFi routers and devices and in higher populated areas like a apt complex or metro areas. There are lots of WiFi and congestion in these areas and not enough channels to handle them all on 2.4Ghz. So as users complain about the problems with there HW here on the forums, we try as best as we can to figure out the problems and see if we can help alleviate the problems however most of the problems are not HW related persae, most of the problems are external conditions as mention above. In these cases we recommend switching to the 5Ghz freqency with other WiFi routers and adapters as this frequency isn't as crowded.

I'm sure there are some other conditions as you mentioned that can effect any Mfr router, networking and the like. As for TCP OFF Load, I would presume this could also be an issue, to what extent, I don't know. I would presume that most Home and or Small business products may or may not support this OFF LOAD option as the average home user would not have any such needs or use for it. Maybe. I would think that a Mfr would want the easiest end user experience for that product line and not have to deal with such options that may be used at higher levels of networking that might be seen more in bigger business or enterprise class networks. By the looks of it, TCP OFF LOAD would be handles at the OS or LAN NIC level and seems to be mainly used on 1 and 10 Gb networks. So I presume that WiFi and any thing less than 1Gb shouldn't be effected by it.

TCP/IP Offload

My 2 cents.

Musart:  Thanks for the info.  I looked at the system event viewer for the time I had the wireless drop for three computers at the same time (reviewed on the Vista machine).  There was nothing logged at the time I lost connection!  It did log my reconnection to the network a few minutes later, however, it did not log the reason the connection was lost at 10:52AM.  Weird.

[Musart]

Tnb:
Indeed weird, surprised that windows did not log anything. I'm not at home right, but I will post a screenshot tonight to make sure that we look at the same screen in the event log, there are so much page to look.

Furry:
Interesting facts. I was to buy a new DIR-655 with HW B (there is a rebate now at BestBuy in Canada) to be able to updgrade to the 2.10NA FW for IPV6 support since I only have the HW A version which can only be upgraded to 1.35NA. I thought that might be an issue...

Also, I was thinking of the packets size management when playing online games, there is so much streaming information in a short time that I was thinking that a setting might be set to better manage the data flow.

But I'll test the channel settings. If I understand, on some occasion, the router might intentionally drop the connexion to do a channel rescan when set to AUTOSCAN isn't it? I thought it was only at the initial connexion.

I might look at the DIR-825 which support 5g but the DWA-552 cards does not support 5g and my cordless phone are on DECT 6.0

As I soon as I get some infos on my findings, hopefully positive, i'll post them.

Thank for the support.

[FurryNutz]

IF you get the Rev B router, Please do not update to v2.10. Please run the Rev B router. IT's not always necessary to upgrade FW. Run the router out of the box first to see.

For gaming, review this:
Gaming and QoS for XBL

If you look at the 825, there are other 5Ghz alternatives for adapters, DWA 160, 182 and DAPs that can go 5Ghz.

Are the DECT phones on 5Ghz? Can you find the specific freqency?

[Musart]

@tnb: Sorry I can't find a way to upload a picture...

@Furry: Cordless Phone: Uniden 1580 DECt 6.0 operate on 1.9Ghz band

And BTW I noticed that my router never keep time uptodate. Does the time reset when I turn off the router for resetting the connexion?

[FurryNutz]

Ok, then shouldn't bother 5Ghz.

To upload a photo on here use a photo web site like photobucket or imageshack. Post the IMG link here and then it will display in the post.

[FurryNutz]

Will it keep time if you use the NTP server option?

Thank for the hint.

This shouldn't bother using a 2.4ghz router-Wireless card neither.

Anyway, I'm trying some setting you suggested on post #5 (One by one, btw). One of my concerns is DNS Relay was OFF, so I'm trying it ON now.

Will it keep time if you use the NTP server option?

Never use NTP but I've just set the ntp1.dlink.com to see if it's works over time.

Thank you very for your prompt replies...!

I'll keep you updated.

To Furry and all posters,

I've read this string and I see one important consideration is missing, HEAT!  When I first bought my DIR-655 HW A1 back in 2005, it dropped connections all the time.  I exchanged it for another at the store and the new one dropped too!  Then it dawned on me that where it sat on my closet shelf, with the modem flat on top, was not allowing enough air circulation.  (Linksys products were designed to stack in those days) So I wall mounted it where it was clear of any air flow blockage.  Problem solved!  I suggest that the posters with extreme connection dropping problems reposition their router and even try a small fan directed at it to see if that makes a difference, because it did for me.
