Title: Iphone 3.1.2 Connection Problem SOLVED.
Post by: Victorinox on December 26, 2009, 05:27:35 AM
 ;)  I found solution for Iphone 3.1.2 connection dropping out / password reentry problem.

So far my phone didn`t lost connection to DIR-825 Rev. B1 for 24 hours. I`m streaming Pandora with no dropouts / password re entry. Prior to that it was disconnecting every 10-15 minutes.

This solution should also work for another D-Link routers as well.

Here we go..

Go to Advanced > Advanced Wireless and change beacon period for 2.4 Band to 75.
Change RTS Threshold to 2304, Change Fragmentation Threshold to 2304.
save settings. Done.

Tried these settings with my 1G ipod touch running the most recent firmware and it seems to have potentially fixed the problem. I have browsed the web on it for 10 mins and am updating about 10 apps from the app store. I have only been running it for a few hours but it seems to be working. Will post back in a day or so to update. Thanks for the info! this has been driving me crazy and made the ipod almost unusable for internet functions.

Been trying out these settings for 5-10 minutes and no connection problems yet, so far it seems to have fixed this issue. You rock :)

How did you come up with these numbers?

How did you come up with these numbers?

I bit of research and 20 years in IT.

Amazing thing is that D-Link own engineers  didn`t came up with these numbers.  What a shame.

BTW.
40 hours and not a singe disconnect. Network thrououtput is the same on another 3 laptops.

I have now been running it for a day and a bit and it is a solid connection once again! Thanks a lot! I had been fiddling with those numbers as well but hadn't hit a combo that had worked. It is interesting that dlink hadn't been able to figure this out and add a little section to the knowledge base. Well, I guess it takes a community with interested people to figure these things out for themselves if the developers are unwilling or unable to.

I attempted this with my D-Link DIR-655, and it did not resolve my issue. My IpodTouch connects, however when i try to load anything with the net, it fails, no data is being recieved by the Ipod even though it says its connected.

Anyother Ideas? I have tried activating security, deactivating it, MAC filtering is off, the SSID is not being broadcasted, not sure what else to try.

You have 3 numbers to experiment with. I don`t have 655 nor Touch. I`m not even sure if different generations of Touch have the same hardware.


It seems that only  3.1.2 firmware affected with this bug.  INHO there is no benefit having 3.1.2 on Touch anyway. Downgrade to 3.0.1 or send me your hardware, I might be able to fix this. :)

You are the man!  I was going to return the router because it was causing my wife some grief everytime she used the iPod.  Now the issues are fixed.  I really didn't want to return it because streaming video and gaming have gotten so much faster and smoother with this router.

Thanks!

Just setup my dir-825 today and immediately saw this iPhone 3.1.2 disconnect issue. Fixed up the router wireless settings as recommended in this this thread and will report back. Only 5 minutes since I switched so far so good.

Haven't seen an iPhone disconnect since making this change. I was getting disconnected previously in like 10-15 min of browsing but I've since taken a phone call for a good 10 minutes and now am surfing this forum and no problems. Thank the original poster for making this thread, this problem would have quickly driven me nuts.

I had a similar problem with my wife's Ipod touch ver. 1.....The ver. 2 works well but after changing the settings.....even the ver. 1 is working good.....thx. for the research and help.

Just had a disconnect this morning while surfing Apples website. Asked me for my wireless password again. Guess this isn't 100% resolved :-(

If you changed anything in network security/settings You`d have to reset network connections on your iPod.

BTW. I`m using WAP2 AES security settings on my IPhone, no dropouts so far.

Try this:
 Go to Advanced> Advanced Network> UNCheck enable UPnP.

Iphone asked for password in 5 minutes after as I checked it.

Did a shutdown and reboot on iPod and it fixed the problem.  I can't disable UPnP.  Too many things on my network rely on it.

I've adjusted the router settings AND reset my iPhone network connections but I'm still having intermittent drops where the iPhone asks me for my wireless password again. There's no pattern. I haven't disabled uPnP I guess that's my last resort.

Post by: Victorinox on January 12, 2010, 08:15:35 PM
Just to be clear. This bug is not DIR-825 specific. It`s Apple 3.1.2 upgrade.  Previous version was more stable. This problem is all over apple boards as well. Linksys, netgear, all required a bit of playing with settings to make it work.

Apple funny boys don`t believe apple is at fault... as usual. ;)

Hi I have a dir 301 & also had drop out issues with my i phone 3gs until i read your solution....

I had the usual re-enter issues & would occasionally connect.

It would connect ok with no security or WEP which i lived with for a short while, However never felt comfortable knocking security back to WEP after bieng WPA enabled before purchase of i phone.

I ve gone for WPA TKIP & used your no's in advanced settings & has now been running for over a week now with no probs....

Bearing in mind that it was any WPA setting made my iphone diconnect etc...

Feel much better having WPA back again......

Thanks you re a genius !!!

Regards

Ed

It works! I've run with it all day, lots of data. Never used to run more than a few minutes before. No problems at all.
How on earth did you figure this out? Could you see log files on either end to get a clue on the problem? Were you able to sniff the wireless connection somehow?
What do these setting even do? Does it degrade performance in any way?

In any case, great that you solved this. It was a major pain. Sad that Dlink never even commented on it and that Apple has let it languish so long.

how he figured out the numbers? just take a look at other routers.. they have these values as default ^^ for example linksys..

I don`t know with how many routers you compared. Some older routers (Linksys included) has 75ms as beacon intervals, threshold numbers are completely different.  I also have WRT610N and WRT160N and they have different numbers as well.

Understanding what those numbers means is the key.

BTW. My solution is not universal. Some iPhones/Ipods still disconnecting/asking for passwords.

Do you have better solution. I`m sure we all appreciate your input.

Thanks for the solution!!!

I just purchased my Iphone 3Gs and I have a DIR-825 router. Before I wasn't using the wireless I just had my stuff hooked up via ethernet. Now that i have turned wireless back on it doesn't seem to be broadcasting or for some reason my phone isn't picking up the signal? Any ideas? Pleas help

it just partially fixes the problem. Indeed I do not get disconnects from the iphone anymore. But now the router goes through power cycles. The iphone now causes these message.

Jan 28 00:50:37 Wireless system with Mac address XXX deauthenticate reason 3
Jan 28 00:50:15 Wireless system with Mac address XXX assoc success
Jan 28 00:50:15 Wireless system with Mac address XXX mc 1/16 uc 3/13 key 2 caps 0x0
Jan 28 00:50:15 Wireless system with Mac address XXX, sta authenticated
Jan 28 00:50:15 Wireless system with Mac address XXX recv auth frame with algorithm 0 seq 1


*I replaced the real MAC address with XXX

The result is, that existing SSH connections to remote hosts drop. This is very unpretty.

Victorinox... any ideas?

iPhone firmware was just updated on the weekend to 3.1.3.  I haven't given it a full test but I haven't noticed any disconnects so far from my wifi.  Hopefully this was a bug fixed by Apple.

Those values didn't fix the issue for me.  It made it BETTER for sure, as it didn't disconnect as frequently, but I was still getting disconnects even with Victorinox's suggested numbers.

So far, knock on wood, but since Sunday that I updated to 3.1.3 I haven't had a disconnect.

 :D  Thank you, thank you, thank you!  You have solved this problem for me.  I have been puzzling over it for some time and only now began looking for advice.  I have an iphone 3G.  The problem, losing connection with an "incorrect password" message, persisted with the installation of iOS 4 (contrary to another user's experience).  Changing the three wireless settings seems to have cured the problem.  No lost connections for two days.
