Post Tribe 1 upgrade makes networking flaky

[Jamu Kakar]

Binary package hint: linux-source-2.6.22

I installed Tribe 1 on a rev 3 Macbook. I followed the instructions
here [0] to get madwifi-based wireless networking and proper native
panel resolution working. After that everything worked great. Today
I apt-get update && apt-get upgrade'd and in the process lost the
ability to use wireless networking with the following output when I
try to set it up manually:

$ sudo dhclient ath0

I switched to the wired network and found that after a certain amount
of data is transferred (I would guess about 512MB) the network just
dies. The only thing I've been able to do to fix it so far is reboot.
I can reproduce it by copying a large amount of data. If I run 'ping
google.ca' at the same time as the transfer it eventually dies with:

ping:sendmsg: No buffer space available

fabbione has suggested trying and older kernel and seeing if the
problem continues. Will do and report back.

Networking works flawlessly for me on a MacBook Pro v2 from november 2006. I guess the network adapters are the same on the MacBook v3 (and thus the drivers).

- wired:
02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 22)
driver: sky2 (from Gutsy)

-wireless:
03:00.0 Network controller: Atheros Communications, Inc. AR5418 802.11a/b/g/n Wireless PCI Express Adapter (rev 01)
driver: madwifi-ng (from madwifi.org SVN).

I had noticed some random network lockups some months ago, but at least since mid-July everything works great.

Can you provide an report on your situation using an updated Gutsy ?

[Jamu Kakar (jkakar)]

I've since switched to ndiswrapper instead of Atheros-based drivers.
Also, haven't experience problems with the wired connection since
early/mid-July.

Conflicting reports and insufficient information, closing.
