 Ahhhh!No wireless connection...
 Try doing this:

 Take the 50Ohm terminator out of your rg-58 (assuming you're not using utp) 
and see what happens next.

 Say...cant browse the web at those amazing speeds of 1.1Mbyte/s,uh?:)

 Its called reflection.

 In a wireless RF connection you have:

 -Refraction
 -Reflection
 -Interferences (usualy dont affect 10base2 due to cable shielding)
 -Attenuation due to property of the medium (air)

In wlan if one client says ACK and the other receives ACKCC"##"" he will ask 
:"could you please repeat that?"
 This is why you dont achieve such speeds with wireless rf connection.Good 
antennas (or well designed internal antennas),low SWR,etc will improve speed 
and distance.
 This is why some wlan hardware is more expensive than others....
 Apart from that keeping objects away from the antenna (at least) 1 wavelength 
can also improve Tx/Rx.1 wl for 2.4Ghz is ~ 0.125 meters

 The right tweakings will help to improve.
