I just got a new DIR 655 and set it up using the provided disc and a wired connection. Wired internet works great. All of my other devices that are wired via a trendnet 8 port gigaswitch works great on my LAN. However, I am having trouble with wireless connections on my two laptops. One runs XP and one runs Win7. I have the settings stock with the exeption of: I'm broadcasting G and N only, Changed from WAP only to Auto WAP and WAP 2 with AES and TIKS, IPv6 set to automatic. At first neither laptop would connect and the signal would not show up in a network scan at times. Once I changed IPv6 from local-linked (or whatever it is) to auto then the XP machine seemed to connect fine and has no problems. However my W7 machine connects and disconnects frequently. Could IPv6 cause something like this? I have a motorola Cable modem with Charter as my ISP. http://www.newegg.com/Product/Product.aspx?Item=N82E16825122009
Or could this possibly be an issue with WAP/WAP2 only settings?

Try with out any security to test 7 PCs connection.
Then try WPA2 and AES only and test.
Doe it happen if IPv6 is turn off?
Any other WiFi or cordless phones in the area?
Test with single mode G or N.

Shortly after my first post I switched to WPA2 Only and AES only. Speed on my W7 machine improved dramatically, however I still get bumped off of the connection after a few minutes. If I leave the PC sit there it will eventually reconnect. Sometimes it will reconnect with internet access, sometimes it will just reconnect to the wireless and give me LAN only access.

I disabled IPv6  on my W7 machine-does not fix

Numerous Wifi in area. My signal is double the closest one. Previous Rev A DIR 655 did not have issues. I also fixed the channel to 1 which no one else is currently on-did not fix. No cordless phone.

Tested in single G and N mode-did not fix.

Apparently getting dropped from the wireless connection is not limited to my W7 machine. While trying to post this my connection failed. Waited a few seconds and WinXP reconnected automatically.

Tested with no security-did not fix. As matter of fact I can't even connect to the wireless at all now with the W7 machine. Thought maybe it was because IPv6 was still uninstalled by I reinstalled it and still won't connect. Windows just says "Unable to connect to....." and trouble shooting returns zero help. Windows can't find the problem.



EDIT: Played around some more and my W7 machine won't connect for the life of me. took down the windows firewall and it connected once with limited access. Then I was kicked off shortly after. XP Machine runs much smoother but still has it's hickups. I did a complete reboot and reintals from factory settings with no security. XP machine runs great-haven't seen a disconnect yet but haven't used it much. The W7 machine won't connect. W7 machine connects fine to unsecured neighbor networks, but not mine. Plugged in the old router and the W7 machine connects just fine. Something fishy about this new router. I'm tempted to bring it back and try a different one to see if I get the same problems.

EDIT again: Playing some more yielded that my original router that I claimed I had no problem with would yield the same problem if I set the channel to 1. I found that my xp laptop has a utility to show noise to signal ratio. Channel 1 has about as much noise as it does signal strength. Changed to channel 4 and the ration improved dramatically. Will plug the new router back in this evening after work and test.

Is there a wireless signal/noise ration type monitor that anyone knows as a free download that I could use on my W7 machine?

Try this:

INSSIDER

I believe I finally got this figured out. After analyzing all 11 channels I've determined that 4-11 are best and about the same in regard to noise vs signal strengths. What I learned is that if you have 20/40 Mhz selected then the router seems to utilize two channels. Having the router automatically select the "Best" channel always resulted in channel 6. I think the problem was that if channel 6 was selected then the secondary channel would be always 2 (CH 1-3 were not usable due to noise). And I think since 2 was filled with so much noise  that that screwed up the connection overall. All I know for sure is that I manually selected channel 10 which then always uses channel 6 as the secondary channel and now everything runs great.

May have spoke a little too soon. So my REV A DIR 655 will allow me to choose channel 10 on 20/40 Auto and pick up channel 6 as the secondary channel. Under Status>Wireless tab it will show 40Mhz Channel 10 and Secondary Channel 6. I set the Wireless adapter on my W7 machine to accept 20/40Mhz auto (intel advanced N agn 6200). My W7 Machine connects to the network at just about 300Mb.

I try the REV B DIR 655 with the same exact settings and any channel above 8 will not bond with another below it. Example channel 9 will not bond with channel 5, 10 not with 6, 11 not with 7. Also under the Status>Wireless tab another difference is noted: What shows as 40Mhz shows as 20/40Mhz and the Primary channel shows but never a secondary channel. So I set it to channel 8 which will bond to channel 4. All is fine. Now, however, my W7 machine won't connect properly to the internet. It connects with limited access. If it sits long enough (several minutes) somehow 8+4 read using inSSIDer as posted by davevt31 changes to just channel 8 and my W7 PC then connects automatically.
The W7 machine connects fine this way but my connection is limited to 130Mb.

Any thoughts on this?



EDIT: As long as my W7 PC doesnt' try to connect the problem with channels above 8 bonding with a secondary channel does not happen. Example: I can select ch 10 and it will bond with ch6.\

[craigap]

After spending some wasted time on the phone with tech support my W7 PC finally (and randomly)decided to connect to the wireless while channels were still bonded, however: It was my thought that the channels were being unbonded by my W7 PC when it tried to connect. I now know this is not the case because I had channels bonded, and without trying to connect my W7 PC the channels spontaneously unbonded and left me with only one channel broadcasting. So therefore I am limited to 130mbps as referenced in the sticky at the top this forum.

And just to reitereate about interferences that may cause this unbonding of the channels (as that is the only excuse DLink Tech support could come up with) is that my Rev A DIR 655 has absolutely no problem staying bonded on any of the channels  I select. I find it resonable to suggest that if one practically identical router prevails then there may be something wrong with the other.

Any thoughts?

Disable the Upnp in advanced networking.  That worked for me.  I had a conflict that two computers were using the same ip address.  If that works it should be OK to re-enable upnp if the conflict is fixed automatically.

[craigap]

That didn't help, but thanks for the suggestion.

I returned the product for a refund. I'm done messing around with this thing.
