#2029: Malformed packets in DHCP challenge
------------------------------------+---------------------------------------
Reporter: [EMAIL PROTECTED] | Type: defect
Status: new | Priority: major
Component: madwifi: other | Version: trunk
Keywords: | Patch_attached: 0
------------------------------------+---------------------------------------
I have an Atheros card in master mode, encryption is off; the client is a
Nokia E51 Symbian phone.[[BR]]
Some specific packets get mangled in the DHCP challenge, which does not
succeed. When i use a standard AP configured as bridge instead of the
Atheros card no broken packet appears. I attached tcpdumps of the
challenges against Madwifi and the Asus AP as reference.[[BR]]
SVN revision is 3746, kernel 2.6.20.3 (Ubuntu).[[BR]]
I tried to disable wmm, uapsd, ff and burst mode, without any effect.
