I finally took the plunge and replaced my "main" WRT54GL with an Asus RT-N16 running Toastman 7493. In all the excitement, I forgot to change the TX and RX antenna settings from "auto" to "A". The router has a single Hyperlink mast-mounted 120-degree 17dBi sectorial antenna. In testing, inSSIDer shows that the "A" antenna is the one closest to the power jack. (It's "B" on the WRT54GL). Despite my oversight, everything seems to be working OK, apart from occasional random connection drops of some of the WDS slaves. I'm hesistant to make any changes to the main router, because every time I do, some of the slaves don't reconnect, and I get mildly irate phone calls from frustrated users whose slaves stubbornly refuse to reconnect even after a power cycle. Can somebody please enlighten me as to how the firmware handles antenna assignment? I removed the 2 extraneous rubber duckies from the Asus, because the nearest AP is 0.3 miles away, so everything is being handled by the Hyperlink on the "A" connection, with router set to "auto". Could my oversight be the cause of the random disconnects? It's a G-only network, 2.4ghz band only. TX power is set to 60, per Toastman recommendation. Thanks as always to Toastman et al for their outstanding work.
