Am I the only one having these problems? ath9k hasn't worked well for me since
2.6.29.4; every snapshot since then has suffered from random drops. In
2.6.29.6 it at least would quickly reassociate. The current ones hang within
20-30 minutes of use and never come back. The compat-wireless snapshots have
all been equally unusable.
