Hello Jack, I'm sorry for the late reply, your message ended up in the spam folder. If your problem still persists: Is Youtube performance back to normal if you revert to an earlier version of the browser, like 38.2.0 or whatever you used that worked?
Hi All--I realize it's like a month and a half since Chris first
responded to my problem. I just wanted to say I appreciate the reply,
and the main reason I dropped this issue is my wife gave birth to our
first child (a son) three days after Chris's email... it's been a wild
ride ever since!
But to get to the point--I tried reverting back to an earlier version of
the TenFour browser and the problem persisted. Not only that, I even
had the same problem within QuickTime when I used the enabler. I now
suspect that this is actually an issue w/ wifi connection, as I think
that the problem started when our service provider changed. My G5 is
now pathetically trying to utilize a wifi router that our landlord is
sharing with us downstairs and on the other side of the house. I'm not
the most tech savvy guy, so I'm wondering is there some way of getting a
reading/diagnostic on wifi signal quality? Maybe the signal's just not
consistent/strong/fast enough for TenFour to give me a smooth YouTube
Well, congratulations & all the best to you and your family :-)
You may be right about the Wifi/provider. You can test Wifi quality and signal strength with utilities like AirGrab WiFi Radar. There's also a network diagnostics tool in System Preferences>Network>AirPort>Assist me…> (which is probably of limited use) and Network Utility in Applications>Utilities.
If the channel is congested maybe your landlord is kind enough to switch to a different channel. If signal strength is too weak there isn't much you can do. Maybe installa Wifi repeater. The best solution would be an ethernet cable to your own router or to enable Wifi in your router, if that's built-in.
