Ok. I've had it.
I have a MacBook running OS X 10.4.11 including all the newest software updates.
I have been trying to use a BitTorrent client for months now and it does not work anymore (it used to work!). I used to have Azureus and I used it to download the occasional TV series like My Name Is Earl or now Terminator: Sarah Connor Chronicles and all was fine and dandy. Then I updated the client and the shit began:
Whenever I let the client run for a bit (1 min to 1h) my internet connection crashes and does not restart. This happens regardless of the client. I went from Azureus/Vuze to XTorrent and now to Transmission and it's always the same.
I set up my portforwarding on my FritzBox 7113 router thingie and Transmission confirms that the port is open and not blocked by firewall.
I turned IPv6 off.
I basically did everything like all the FAQs and How-Tos say I should.
Still, after the client runs for a bit and gets good speeds up to 300k/sec, it will just crash my internet connect so that the router disappears from the AirPort WLAN networks list. I then have to turn AirPort off and back on to even find my FritzBox in the list of all the surrounding WLANs. When I click on it, everything is back to normal, but when I start the BitTorrent client again it just crashes again after a very short time ...
Can ANYONE help me out? I just wanna watch some shows that are not on German TV ...
