Hrm ... so I have this one in my T520.

I've been experimenting with routers and such ... and I found something
*interesting* with iwn(4).

On my dlink dir825-C1 I have a channel option "HT20/40 Coexistence".  If
I disable this, I cannot associate in the 2.4G hz channel at all.  I
don't know if this is clueful, but it seems to mirror my problems at
work.  Associates for a moment and then drops.

Since I don't know what this really means, I thought I'd chuck it over
here and see if its meaningful.
