Hmm, thats too bad.Because when our DGL's start dying (is going to start happening sooner or later) what do you think will be our replacements? The 855? I am personally thinking about trying one of those Asus routers with dd-wrt. They offer some pretty nifty features.

[FurryNutz]

Will find me a used 4500 till I can't find anymore. 

I wish they made the DD-WRT FW a little less advanced. Soooo many options and seems a bit less intuitive.

Seems I have spoken to soon.
Only starting today -  I saw "Wireless Restart" in the logs.
Once at 7:42am and another (so far) at 1:33pm.

I am going monitor this and if it happens again I will try locking it on a specific channel (instead of auto) - although it did (not) change channels when it did its restart.

Now why after 6 days of being a good little router, has it decided to act up ?!

At least there is ONE difference from the last router - in that this time, the Wireless Restarts were not accompanied by DE-Auth and RE-Auth of the wireless clients - these restarts are all alone by themselves.

Hmmmmm.....

[FurryNutz]

You have any Iphones?

Try locking in Chl 11.

[icemankent]

Yes - one iphone4.

What is the relevance to channel 11 ?

[FurryNutz]

Been told it give the best connection and performace. Does the wireless restart happen if you put the I4 on a static IP address?

[icemankent]

All my wireless clients have a reserved IP address.
This makes troubleshooting easier as well.

I can try changing to ch 11 and see what happens (it is on ch 9 auto right now).

[FurryNutz]

I might also try shutting down all wireless devices for a test accept for one and see what you find out. I presume you are using the default Wireless mode of mixed? If you don't have any A or B devices, you could try Mixed G and N. No need to broadcast what modes your not using. I would save off your configuration to file at some point so you can go back should something really go wrong while your tweeking. 

[icemankent]

Nothing fancy on my router.
Using "g" only.

It was working fine for 6 days, then - well, you know.

No changes in environment or configs between when it was behaving, to when it decided to throw in those two wireless restarts to make my day more interesting.

[FurryNutz]

did it give an ip address if the restart and whats connected to that IP address?

[Hard Harry]

Hmm, I did some digging around and its a pretty complex issue. Theres a couples issues going around and a TON of misinformation so its hard to dig through the BS. Most of the issues you have already resolved with the DHCP reseverations, channel 11, and WPA instead of WEP. There was another more subtle problem I saw a trend of, and thats with most Iphone 4, and the later patched Iphone 3G. Seems there is a firmware bug with the phone handing off encription confirmation using WPA with AES. Iphone forgets the key, so requests a new one, so the router restarts the wireless to regenerate a new one. When I say key, I don't mean your pass phrase. This someone ties into the use of 3G though. Maybe it something about 3G requires it to send keep alive signals to network, so has to switch from Wifi to 3G? Maybe its interference from the antenna itself? I cant find info on it other then user experiences, and most of those are less then accurate. And you know how Apple is, if its not in their support site, your imagining the problem. LOL. So things to try:

1. Try turning off 3G on your Iphone and see if they helps. If so, they call Apple and report, and likly its a firmware issue.

2. Try changing from AES with TKIP, that will hand over the encription to the OSi software, and avoid the chip(and firmware bug) causing the issue. There are other problems associated with TKIP though and the Iphone.

3. Make sure your Iphone is set to G only, since the Iphone 4 is the first to be capable of N.

4. If all else fails, try to keep your Iphone off(100% powered down) while in the house. If nothing else, if it happens even once with the phone off, it confirms its not the phone. In retrospect, probably be a good idea to try this first.

[icemankent]

Just a quick update.
I have made no changes (yet) , but checked the logs frequently.

There have been no further instances of "wireless restart" since 20-jan-2011 @ 742am and 1:33pm.

I will continue to monitor this before I try any changes to config or otherwise.

[Hard Harry]

Ok, I think it has something to do with your Iphone, 3G and the security process of WPA with AES. And if I had to guess, something simular to how my G1 would randomly broadcast some kind of signal that would actually create ripples on my kitchen TV if it was too close to it. Never if I was in power conserve mode which would turn off 3G.

[icemankent]

Ok, so this morning my 4500 decided to HANG.
(UP time approximately >4 days)

I was trying to browse the internet on wireless AND wired pc's.
I could not even connect to the router's own web interface on either pc.
I WAS able to sometimes get sloooooooow (eventual) connectivity to "some internet sites".

As far as wireless - still had good connectivity (strength and speed) - so the wireless part of the router seemed to be ok.

It is just the router, itself that wasn't doing any routing.

As a result - I just updated to 1.23na - so we'll see what happens now.

[FurryNutz]

OK sounds like v1.21 strikes again. 

Should see any with v1.23.

Keep us posted.
