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. sean [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJTRJ/mAAoJEBkJRdwI6BaHevEH/2BSkdq2+pUdLTo3IXeEgJVc 4efw/g4nWBWl0EC2617S7eGJeUFPBWiD+MuYI4AsIb7RB6Zcep7c4zc76/85Bwkh 1HTxcooQvIL082J1J12+jg7xTjh0tyqCDjZUawhTnMr0pm5+IrZ5Rr+yQUJUhO4k lc/cDnb3tYykUvoxa00nU6EyVdvfzDFzpwYkcy8S7RYizLlrynKJcoZkwxHyD9xz xIwfYIGFJWeEJA0I5HNI/QOhjQKGCejZS3zfvv0hyodnBKYcGH7iimos15gj9ZE5 ItYdbbnQ86R9r+OscLctYr9u6YnSlJNonZN2s2O8EnuJkkPdj5s6X6oQQteLJRI= =2P2D -----END PGP SIGNATURE-----help
