Both specs are stated compatible. All rates well within both specs. No problem within the main spec criteria, so "beefier" does not seem to apply at all. How can you presume any reason if you have no knowledge of the specs and don't state a possible cause? > > 3) Download rate by WiFi in a clear 54MHz G channel with high > S/N is only > > about half the rate of a wired LAN connection.. why? > > > You may be confusing frequency with bandwidth.

Data given above stated "clear channel with high S/N" Are you saying that I should get the same ~15Mbps on WiFi as LAN per Charter's speed test? I think I should, unless there's some detectable overhead. that I have not been able to identify or detect. Chuck
