Besides the usual "interference" things you'd obviously think about - shared channel, microwave ovens, "SMART"meters!, and other RF transmission sources - there are some things that you might not ever think of, such as:
- Having the WLAN device TOO CLOSE to the receiver! (They should be AT LEAST 2m apart, 4 or more IS BETTER!
)
- ANYONE within 100m using a SATELLITE DISH.
- Sunspots/ambient ionic sources.
- Poorly/non-grounded electronic devices on the same circuit panel.
- FLUORESCENT LIGHTS
- Garage door openers
- CB & Ham radio users
- Overhead/nearby air traffic

I should add one new bit of info that I forgot to include in the original post:
Look through the WLAN documentation and figure out how to DISABLE 802.11
a &
b .
[If your WLAN device does not support 802.11 g or n, then ignore all this: You're stuck with what you've got.... ]They are long-since out of date, and your WLAN device will try to "fall back" to use them when it's having connection problems. If you're "on the edge" of such a problem the device will CONSTANTLY CYCLE BACK AND FORTH trying to get a better connection, ending up doing more HARM than GOOD.
In fact, if you KNOW that you only connect through one of "g" or "n", then see if you can disable ALL the others and just force it to use the one that you actually connect with.
