iPhone 3G S - YouTube over Wifi issue (Please help me verify this)

Hello.

This is happening on my iPhone 3G S on WiFi. It does not happen to my iPhone 3G either on Wifi or 3G.

I need to see if others are having the same issue to see if it's a bug or if my phone is defective. On YouTube (WiFi only) my iPhone 3G S will only load a minute to a minute of half of video and it quits loading. What happens is the phone will play up until that point and then suddenly it stops playing and pauses. When you look at the controls for YouTube it shows that it has played all of the downloaded data.

I tested with my old iPhone 3G on the *very same* Wifi and it does not have this issue and both are running iPhone OS 3.0. I really need somebody else with an iPhone 3G S to verify this issue for me (or tell me that it doesn't happen to them).

Here is a video that I am having trouble with so you can test yourself:

Please test with your iPhone 3G S and post here and let me know.

Dell XPS M1530, Windows Vista

I had a video-locks-up with the OP's video and also some others. The problem seems to have disappeared after I restarted my two back-to-backed AirPort Extreme routers and my cable modem.

I have two connected AEs because one does 802.11n and the other, which hooks directly to the cable modem, does 802.11g. I probably ought to reconfigure, but I doubt that's important. What seems to be important is that restarting my network gear keeps seemingly all YouTube videos from locking up.

Based on earlier posts in this thread, it seems only the iPhone 3GS has this problem, not other iPhones, and only when using WiFi, not 3G or EDGE. My interpretation is that something odd is happening in which the router (or just possibly the cable modem) is involved in some kind of anomalous situation (perhaps a packet gets dropped), and, when that event interrupts a YouTube download, the 3GS can't recover. Nor can the router, on its own. Restarting the router (or modem) clears it up (at least, in my own case, it seems to).

I don't know if this would carry over to non-Apple routers.

If I'm diagnosing the problem right, I have to hope revised iPhone software would allow it to "kick start" a stuck router without any user intervention. That is, I imagine the real fault in in the iPhone software's error recovery capability, even though the router is where the error crops up.

I have found the issue occurs less when the router is set to G-only and even less when set to B-only. Any sort of mixed wireless environment gives the 3G S problems.

The issue is not with the Router but lies with the software/firmware of the iPhone 3G S as this doesn't happen with any of my other wireless devices including my iPhone 3G.

I have found that simply dropping the wireless connection in Settings->General->Wifi and then re-starting it will allow me to view most of the video before it freezes (and sometimes all of it).

From all I've read it seems pretty clear that this is a bandwidth matching issue that is causing an error condition. The YouTube app tries to match the quality (and bandwidth) of the video to the Internet bandwidth that the iPhone has at the time. This is why the video quality at 3G is lower. When on a wifi G connection, with a theoretical speed of 54mbps, the YouTube app decides to send the highest quality video stream, and clearly for some reason the iPhone can't handle it and gags. If you drop your wifi to only B mode, with a speed of 11mbps, the YouTube app picks a video quality that the iPhone can handle and things work better.

So that, I believe, explains the problem and why some workarounds work. Hopefully Apple will provide a real solution.

You are speculating and I would have to guess that you are wrong - if I connect on Wireless G ( with B, G, and N available ) and try playing a LAN Game of say... Monopoly it will drop the connection every 1 to 2 minutes where as if I set the router to G only it only drops every few minutes (2~4 or so) and then if I set it to B only it rarely drops the connection.

I've noticed this is much better with Firmware 3.1 but it's still not perfect (i.e. showing low signal when very near the router) but at least it's not dropping connections nearly as much.

Yep, same problem! I have 30 mbps on Macbook with my Wifi speed test and on mobile speed test I get 11.6 mbps download and 0.94 upload. I have the same exact problem. Youtube is extremely slow. I also don't have the luxury to switch to WEP since I have an airport extreme which DOESN'T HAVE A WEP OPTION. Also can't switch to just b on airport extreme, you're stuck with the dual band. Maybe I should stop buying apple products all together! Called apple support the guy told me to switch the channels from auto to manual and pick different channels on my airport extreme. Everything else seem to have improved except YouTube. It is dreadfully slow and I constantly need to switch to 3Gs to watch grainy videos. This is unacceptable!

RESOLUTION:

I have resolved the exact same issue by changing my wireless router to B/G mixed from the "mixed" network mode, if you use a wireless router log into it and go under wireless then network mode and switch to b/g mixed or set it to "G" only this will fix your issue, do not use the "mixed" only setting. Hope this helps a lot of people out there:)

I have an Air Port Extreme and an iPhone 3GS and I'm having the same problem described here. Youtube videos will play about halfway through until buffering stops and then the video eventually freezes. Changing my router to B or even G isn't a solution because network access for my Macs will be slowed down also. This is really annoying because I'm a Youtube addict and I can't watch my videos. Please fix this Apple. Thank you.

I am having the same issues, just upgraded from the 3g to 3gs, did not have this issue with the 3g, wifi sometimes will not connect at all to the internet and the signal strengh fluctuates even when standing next to the router. not sure what to do adout this, tec support had me do a system restore but that did not fix the problem.

I'm having this problem on both mine and my wifes iPhone 3Gs. It never happened on our older Gen 1 iPhones (and still doesn't with them set to WiFi). Basically all the same symptoms as everyone else. Video loads over WiFi only to about 1.5 minutes and then freezes, poor signal strength when standing right next to the router, etc.

I'm also using an Airport Extreme. Can someone tell me how to set it to 802.11G ONLY? I looked through the AirPort utility and didn't see that as an option.

I tried the "Interference Robustness" option and it didn't do anything except slow down the time it takes to buffer to the "freeze-point". I submitted feedback with the link on page one of this thread. This <Apple won't let me use the word that describes what a vacuum cleaner does>!
