Bugs found in Leopard from someone who recently switched.

I can't add much to the knowledge on networking; I can however add my agreement that Leopard is less tolerant of crappy connections. On my way to Iraq I had to stop in Kuwait for 3 weeks. They had free internet and all my windows buddies were cruising along (Slowly) with the crappy internet, but when I connected some pages worked, some did not. It seemed to clear up at about 2 am when no one was on the net and I had a more stable connection. Is it possible that you have a slow/crappy connection or a slowly dying router?

Doesn't seem too crappy for me... but I will surely try and connect to other networks to see if anything changes...

BTW, is the Linux kernel as tolerant as Wondows? Because I don't have problems connecting to the internet with a live distro...

EDIT: ping count to router 1000/1000, and 0% packet drop.

EDIT2: ping count to www.google.com 1000/1000, 0% packet drop
 
Sorry, I didn't mean to imply anything bad, I was just trying to help with my very limited experience. I just noticed the similarities between your problem and mine experienced in Kuwait. Now that I am in Iraq and have my satellite my internet is more stable. I did notice though that the problem in my case was not the router at all, it was the internet service.

No offense taken! I actually spent more than 1 year with a UMTS connection, using my cellphone as a modem: THAT was crappy!


EDIT: now I can't reach www.google.com anymore, AGAIN. BUT I can still trace a route to it...
 
BUMP: google coming and going, the Dilbert widget can't fetch the comic strips anymore (but when I click on it, it correctly sends me to the website... strange...)
 
I would try disabling ethernet all together in the Networking section of System Preferences. You can safely delete it from the available networking ports without losing the ability to easily re-add it later on if you need to use ethernet.

I only say this because I find it incredibly irregular that any traceroute you make would default to using en0 (built in ethernet) over your airport connection (en1). Best to take the ethernet out of the picture all-together.
 
I tried...

Here's the result:

Are you really using IP over Firewire?

Exactly my point: I can't understand why, priority-wise, the Airport isn't the first selected...
The fw0 interface became the default after I disabled ethernet en0, which I never used anyway (I've had my MBP for 3 months, and always connected through the Airport)...

The symptoms seem like you are losing your wireless connection. If your Airport is the first interface in the service order it should be used first - if the wireless connection can be made. Otherwise Leopard is going to try other interfaces if they are enabled.

Leopard isn't running any dynamic routing protocol, it only knows the one default route to your router. When Leopard says 'no route to host', that's an indication that your one working interface has gone down and it can no longer talk to your router..

You can verify the service order in System Preferences/Network and clicking on the gear icon in the lower left. You can also force the other interfaces to inactive if they aren't already. At least that will eliminate some variables.

My wireless connection seems to work perfectly (Azureus has no problems at all), and it 's "only" a few sites...

I checked and Airport hs always been top in interfaces priority.
I deleted all the others anyway, just to be on the safe side.

Summary:

I can trace www.google.com with lft.
Sometimes I can connect to it (and of course use the traceroute command), sometimes not.
Gmail: while I'm writing this, I managed to connect (just once, mind you), enter my username/password, and get the same "can't extablish a network connection" error. Now I can't even access the front page.
I still can't trace a route to it, not even with lft.


Any ideas? Apart from wiping clean and installing Tiger (which would give me the benefit of a stabler performance with Logic 8)?
 
Guest I found the biggest bugs in OSX of Vistas, is probably the widgets. Why are there two dialogs for each of my programs on Leopard AND NOW VISTA!!!😡
