This is driving me absolutely crazy and has rendered my laptops unusable for web related work.

I have DIR-655 A4 with 1.32NA 11/05 firmware on it (trying to solve this very problem)

I have 6 wired connections:
* 2008 server R2 as Hyper-V server
* Win7 VM as internet browsing machine
* Win7 VM as music library and SlimDevices server
* Win7 Media PC
* wireless music streaming device (Squeezebox2)
* Sony PS3

I have 4 wireless connections:
* my laptop
*wife work laptop
* wife Netbook

The problem, like so many others around here, is that my wireless connection drops every few minuets. Looking at the log, I can see that there is a Wireless restart every few minutes as well.

The other thing "fishy" in the log is a tremendous number of "UpNP renew entry", and a substantial number of "Blocked incoming UDP packet"

I updated to the newest firmware, am running WPA-2 security, turned off secure zone, and unchecked DNS relay. How can I fix this dog? As it is, it's useless to me except as a wired router...

Thanks,

Kook

Anybody? Bueller? Bueller?

Seriously, I just counted the number of restarts in my log in the last hour and it was 20 restarts! That's an average of once every 3 minutes!!! You've got to be kidding me!

Do I have something absolutely wrong in the configuration, or is it something else?

[lamonsas]

do u have wifi protected setup enabled or disabled? what is the TRANSMISSION rate set to? in the advanced TAB, under ADVANCED WIRELESS, do u have "extra wireless protection" enabled or disabled?

[Coastie]

Like you, my wireless connection constantly restarts . At least I now know, I'm not the only one. I contacted Tech Support a couple of weeks ago & told them I had a new unopened Netgear router that I was about to replace this friggin D-Link with. I was assigned to a USA tech support person. He had me adjust my RTS & Fragmentation Threshold to 2100. Don't know if that was an educated suggestion or merely a "hail Marry" on his part. Seemed to improved things slightly, but I'm still being plaqued with constant restarts. Trying the forum approach before I completely abandon the D-Link.

coastle, do u have wifi protected setup enabled or disabled? what is the TRANSMISSION rate set to? in the advanced TAB, under ADVANCED WIRELESS, do u have "extra wireless protection" enabled or disabled?

[lamonsas]

and also , what do u have your CHANNEL WIDTH set to? 20mhz or 20mhz/40mhz auto?

[obkook]

Thanks for the reply!!

For me:

WiFi protected setup - enabled
Extra Wireless Protection - checked
Transmission Rate - Best (Automatic)
Channel Width - 20 MHz

Do you recommend changing any of these settings?

[lamonsas]

yes , change the WIDTH to auto 20/40mhz, and turn of Wifi protected setup and extra wireless protection, tell me if it helped anything.

[lamonsas]

and btw just so u know DNS RELAY should be enabled , not disabled.

[obkook]

OK, all changes made, and I'll enable some of the wireless clients now and see how things go. I report back in about 20 min or so.

[obkook]

nope, I can already tell that it hasn't made a difference - 19 wirelss restarts in the past 5 minutes.

[Ozzed5]

Wow, sounds frustrating.

Hi
I can se you have IPV6 turned on try to only use IPV4 and try to
turn brodcast on 255.255.255.255 is a broadcast packet.


Some hints to test !

OK, I have narrowed this down a little bit.

The Problem is caused by my wired  PC. I have a wired 2008 R2 server running Hyper-V with 2 VM's running iside it, both also attached to the router (via the host NIC).

I little further digging has shown others on this forum to likewise identify a wired PC to be the cause of a "wireless restart" issue. http://forums.dlink.com/index.php?topic=5851.0 in particular.

In the linked post, he was able to narrow it down to the Symantec Endpoint Protection firewall, and guess what? I have SEP on this machine as well!

It also occurred to me that the VM's might be somhow confusing things a bit, so I just shut them down and there was no change. Shutting down the entire server immediately changed from having an average of 2 wireless restarts EVERY MNUTE to none in the past hour.

Restarting the server immiately started the wireless restarts as well.

So, my question is, does anyone know what specific changes I could make to SEP to stop this?

BTW - thanks for the IPv6 suggestion - I may try that too if I can't do something with the SEP plan...

Here is another potential piece of the puzzle. This was on the DIR-825 as reported on this forum, but it seems to be the same phenomenon.
