If not, what other information could I provide?
You can't do this in HT40+ mode, which bonds together two adjacent channels (36 and 40, 44 and 48), but can't do a channel in the middle (40 or 48) If you want to use 40 or 48 you can downgrade to HT20 mode (which is limited to 150Mbits) Yes there should be some sort of error check for this. I note 802.11ac is different, allowing bonding non-adjecent channels. > Rich > _______________________________________________ > Cerowrt-devel mailing list > [email protected] > https://lists.bufferbloat.net/listinfo/cerowrt-devel -- Dave Täht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.html _______________________________________________ Cerowrt-devel mailing list [email protected] https://lists.bufferbloat.net/listinfo/cerowrt-devel
