If 1.23 does not produce results you can always try downgrading to 1.15 firmware, which I think allows you to downgrade even further if needed. I think it is very stable and many other users, I remember, also had good results with it. Here is the link to it if you want want too try it. just throwing it out there as a last option sort of thing...

Ok - so far, so good with 1.23na.
(Mind you, it has only beeen a day and a bit, now).

So far, no wireless restarts or any other abnormal behavior.

I'll post any updates.

Kewl, keep us posted.

After an UPtime of about 2.5 days, today I received 1 Wireless Restart (at 6:53am Tue Jan 25).
The router did not change its channel - and no other "events" or environmental issues were apparent.
So this seems to be happening out of the blue - relatively INfrequently.

Since it did not cause any disconnections of any clients, I may just learn to live with this behavior - until it becomes service-affecting.

Related to this, I emailed D-Link tech support 2 days ago.
Specifically, I asked them about how they programmed the firmware of the router.
I asked what needs to happen for the router to report "wireless restart" in the logs.
No reply (yet).

[FurryNutz]

OK. well something is going on. I wish we could figure it out for ya. 
Keep us posted.

Consider downgrading to 1.15 fw

Well - today - after 7 days and 12 hours of uptime, I got one wireless restart.

The channel did not change.
The time of day was 11:25 am.

There were no apparent environmental anomalies.
There were no other issues (deauthentications/reauthentications, etc).

So, if this happens so infrequently - with no perceivable impact - I think I can live with it.

I asked D-link to give me mroe info on just what a wireless restart "is" - what causes it, what happens when it "does" a wireless restart.
When that answer comes - (it has been almost 2 weeks now of waiting) - I will post here.

Lastly, I do not feel this is firmware related, as my previous 4500 had this problem in a chronic way, whereas this router exhibits maybe 1% of the issue - same firmware, etc - so leads me to beleive it was the hardware itself - both A2 version.

I will update when I get more info.

[FurryNutz]

Ok.
I started testing my A1 last night. I am seeing a ton of deauthentications/reauthentications and not sure why.
I have forward this info to DLink.

I'm currently on v1.12 and will be updating to v1.23 tonight and testing again and see what happens. I didn't see any restarts from the logs that were sent to me this am. Will look again tonight before updating.

I have 2 1st gen iPhones, a blackberry on 3 month loan and a Mac Book Pro.

I'm hoping to help narrow this down.

After about 10 days of UPtime, my 4500 rebooted itself.
(I am not sure what causes this)

As for wireless restarts, I have received two more - both were about 2 days apart from each other, and both happened in the early morning hours (one at 530am, and the other at around 6am) - with no obvious issues or behavior noted (environmental or in the logs).

BTW, my email to D-link - now 2 weeks old - still has not yet been responded to.

I am just glad that my wireless restarts (on "this" router) have not yet become service-affecting.

Hey Ice,
Was curious, were your Iphones idle at these time frames or active?

Been doing some testing on my 4500 and my 1st gen iPhone. I haven't been seeing any restarts on my A1 HW however I'm seeing a ton of De-authentication log entries for some reason. Even during times that the iPhone is Idle and I'm asleep. Have you seen anything like this in your logs?

I'm curious, would it affect your services at your place if you used just the iPhones data network and shut off the WiFi on the iPhones for a few days and see if you see anything on the router? Log entries and re-starts?

[icemankent]

There's only one iphone4 in the house, and it was idle (5am) when the wireless restart was reported.
I have received a wireless restart before when the phone was not in the house, or when its wifi was disabled - so I have eliminated it as a possibility.

[FurryNutz]

Ok, would be interesting to get a wireless sniffer in your area and see what other environmental conditions could be effecting this router.
