802.11b and 802.11g wireless access points are spread spectrum, so if  
they're operating on a channel that includes your frequency, they'll  
elevate the noise floor somewhat.  If you're in a quiet area and  
trying to work 2.4 GHz weak signal or EME, the increase in the noise  
floor may be fairly significant.  Any spurs they generate will  
probably tend to mirror the spread-spectrum nature of the primary  
operating frequency.  802.11n channels are somewhat wider but still  
on 2.4GHz.

It all depends on how significant the impact is on your reception.   
802.11a, obviously, will be out of the ham bands, and 802.11b  
channels 7 and up are also out of the band (although they can pump  
your AGC if you don't have fairly tight front end filtering on your  
LNB) andat least one manufacturer has gone from defaulting their  
802.11b from channel 1 to channel 11 much to my delight.

(Some 802.11b/g routers also use "automatic" channel selection, which  
means they scan the channels when they start up and pick a relatively  
clear one.  If for some reason you're transmitting on frequencies  
that correspond to low numbered channels, most of these WAP's will  
tend to avoid your frequency even when you're listening .. :) .. just  
saying ..)
