Wireless connectivity is very subjective. The AP541 has been a very solid performer since it's inception.
Verify the follow conditions;
The AP is installed in a centralized location
The Antennas are placed vertically
There are no metal objects, reflective surfaces, major absorbing objects, etc
The AP is installed in an elevated position
If you are using cordless phones or ovens, ensure they are not using the 2.4 GHZ band
The AP can cover roughly 4000-5000 square feet with ideal conditions (my house is 2,499 square feet with 1 acre land, I have no problems to reach around my property)
Here are some troubleshooting ideas;
Download a free program called INSIDDER and check your RSSI and wireless interference
While connected to the AP, check your wireless connection status to see if it fluctuates, if you connect 54 mbs, it should stay there, 130 mbps, should stay there, etc. If this fluctuates, you likely have modulation and lower client associations such as b or g connection
Try to set G or N only and test
Hope this helps out a bit.
