I can't comment on these devices but I sure did have a negative 
experience with a competitor's product:

I bet these are FCC Part 15.  I used to own devices like this and they 
were most noisy between 2-5 MHz (Netgear XAV101).  In order to conduct a 
really good test, I had to make sure I was sending data thru the 
device.  The devices would go to sleep and made it difficult to find out 
the source!  I have since eliminated these devices as they create 
unnecessary hash between 2-5 MHz.

In order to address my wireless signal issues (once I discovered it was 
the source of my noise):

1. Threw out my existing wireless router
2. Bought two D-Link DIR-615 units which are capable to have DD-WRT firmware
3. Flashed both D-Link DIR-615 units to DD-WRT.  One DIR-615 was 
hardwired and broadcasted my wireless signal.
4. The second D-Link DIR-615 was placed in the front of the house to 
repeat the signal in weak areas.

You can do similar with the DD-WRT to make a wireless to ethernet bridge 
as well.  There are many options available to use when switching the 
firmware to DD-WRT.  I need to warn people that flashing firmware to 
DD-WRT is for a limited number of routers.  I would suggest reading the 
instructions first and then read the forums for your particular model.  
The forums may have additional information regarding flashing the unit 
and making it easier since directions on the site may be out of date 
(depending on how new your wireless access point it).

You'll need to make sure the DHCP server is DISABLED on your access 
points (most people are using their cable modem or another router to 
provide DHCP).  If you're using your wireless access point as a internet 
router, make sure DHCP is DISABLED on the second wireless access point.  
Leaving it enabled will only cause unnecessary problems as the second 
wireless access point is only a repeater/bridge and will try to route 
the traffic to a interface which is not connected to the internet.
