What seems to causing this would iwlwifi cannot hear 11a beacon, thus, falling down to 11g.
Some possibilities I can think of is:
Noises in 5GHz bands (usually not, unlike 2.4GHz that conflicts
with microwave ovens, BlueTooth, and some others).

Depending on regdomain, 5GHz range have allowed but restricted channels
unless checking other signals in use (radars, typically) and need wait.

Conflicting with neighborhoods' APs and defeated.

I hear what you're saying Tom but I'm wondering if it's a timing issue as restarting netif and routing after my ThinkPad boots up with a failed wlan0 brings it up solid and no other devices are having this issue in the house ???
