What could be going on with WRT160NL access point, stock firmware that my linux (3.10.4) with Intel Corporation Centrino Advanced-N + WiMAX 6250 [Kilmer Peak] (rev 2c) cannot even connect? The same happened with my earlier Intel 5350 wifi card. It basically reports: [79477.496067] eth1: AP 68:7f:74:06:b3:1b changed bandwidth, new config is 2422 MHz, width 1 (2422/0 MHz) [79477.496072] eth1: AP 68:7f:74:06:b3:1b changed bandwidth in a way we can't support - disconnect (note I have two wrt160nl here and problem happens with both) Any hints on why "we can't support" configuration issued by this (common) AP?
