FACETIME keeps freezing & dropping....

Mine isnt dropping wifi but here is what I posted:

I am having the same problem with My iPad2 white 16gig Wifi only. Im using a new Airport Extreme Dual band router on a 5 mbit down 1 mbit up connection. My friend I am calling is using an iPhone 4 and has a Dual Band Time Capsule with the same network speed. If I call him or he calls me and I use My Mac mini (2.53 Ghz) the call is fine and we can chat all day but as soon as I try and use my iPad 2 the call will drop out after about 30 seconds. I am a Tech for a living and have tried all kinds of network settings to get this working on the iPad 2 but to no avail. Please, Apple, an update to fix FaceTime on the iPad 2 would be very nice. Thanks.

I know I have more than enough bandwidth and that my router is functioning fine. There is a glitch in FaceTime but knowing Apple it wont be too long until all is well.

It's not just the iPad2... I have it on my iPhone 4 now too over the last couple of weeks. Despite what network I use or where in the world i am. It takes maximum 4 minutes to freeze up. i've tried several divices over multiple networks. All 5mb up and down minimum networks...

I have been plagued by the same issue for quite a while now. I "think" I have got it solved - well, I'm 99% sure I have) and it seems to be down to my router.

I have FaceTime on my Mac, my iPad 2 and my iPhone 4s.

My wife has it on her iPhone 4 and her iPad 2

We have been trying to use it ever since iOS 5 came out. It freezes intermittently and I always thought it was down to bandwidth.

Have tried different routers, different connections and pretty much every connotation available to me.

I kind of assumed FT was just "buggy" and not fit for purpose, but others were telling it worked fine.

I'm on a 100mb connection, so I know it's not bandwidth. I have tried different MTU settings, etc, but still lock ups.

Had one conversation with my brother recently, to my overseas "home", and it worked perfectly.

So now I know it works, I have tried other calls - to my house. Everything dies at various intervals. Sometimes it last 3-4 mins, others it lasts 10 before locking up - the other end can see me, or vice versa and hear but the other end hears nothing or a frozen screen.

Talking to my son just now, we had the same problem, but I happened to be looking at the firewall log at the time.

The call started to lock up - it was almost a mobile phone commercial "can you hear me now?"

Unchecked the DoS setting for udp_flood on the router and the call resumed perfectly.

Carried on the call for half an hour and no problems.

Since that setting has been unchecked I have had no issues with FaceTime.

The setting was at 150 packets per second and then blocked it for 10 secs.

Leaving it off cures it, but I am sure that fine-tuning would allow it back on to prevent DoS but still allow FaceTime to work.

I don't normally post to forums, but since this had frustrated me for over a year now, I hope it may solve it for others suffering the same issue.

I wonder what I should adjust on my Apple time capsule router to make it work with facetime? I had to switch to Skype which works great on the ipad.

Please has anyone gotten solutions how to solve this problem?!

Thanks.

Where can one locate this? I have att u-verse. Thanks
