======================================== """""essentially your microvave must be emitting microwave radiation at your adaptors frequency and interfering.

It won't take much energy when the microwave is close to the the "receiver" that is getting interfered with. ============================================ """""Sounds like you have a 'leaky', that is poorly shielded microwave unit. 'Run away, run away!' The frequency of microwaves is 1 x 10+8 to 1 x 10+12 cycles (Hz) per second. Your router and adaptors are running at 2.4 GHz or 2.4 x 10+9 Hz (if I got my exponent correct). So essentially your microvave must be emitting microwave radiation at your adaptors frequency and interfering. I think it mught be time for a new microvave unit""""" =========================================== Also not necessarily. RF from a microwave is not "clean" rf energy, it is rich in harmonics. Also, energy of this nature can "mix" at what is essentially a "crystal" or "semiconductor" such as a loose metal joint. This kind of thing happens all the time at transmitter (mountaintop sites) where there is everything from chain link fences to loosening of tower hardware. ============================================ """""A microwave should not leak at all...even a little is not acceptable.""""" ============================================ Above is blatently untrue, would be like saying that your "drinking water is pure." There is a LIMIT defined in applicable regulations (FCC in the U.S.) that sets these limits. I can't go around quoting what the limits are, so many microvolts per millimeter, or orange peels per chair leg, but there IS SOME allowable leakage under the law. These wireless devices (in the U.S.) come under what is known as FCC "part 15" which partly says that such devices "must accept any and all interferance." What this means, is that if you buy something that works on RF, like a wireless card, a garage door opener, or a keylock for you car door, and it starts to act up because of a nearby transmitter, then under FCC you have NO LEGAL RECOURSE to force the source of your problem stop. You either have to live with it, buy a better quality "receiver" (device) or devise some means of filtering. ============================================ """""That's RF escaping from the magnetron not microwave energy. Since the RF SHOULD be blocked by the internal mesh of the oven the only leak source would be a small portion of the back.""""" ============================================ What do you mean, "That's RF escaping from the magnetron not microwave energy" ???? It is IN FACT R adio F requency energy, and it is in fact RF MICROWAVE energy. Frankly, the leak could be from anywhere, from the door, to poor metal fitup in the cabinet, to a slight bend or similar ill fittup at the magnetron flange. You could have the microwave checked for leakage by a good technician, but few have the expensive RF survey instrument needed. (I did have) It MAY or MAY not be a easily cured problem. If the oven isn't worth much, might be cheaper to "try" a new one. You might explain to a store what the problem is, and see if they have a demo you could try for a day. Tinfoil may or may not help, but be darn careful. Many microwave ovens have cooling vents here and there, and you do not want to cover them.

Thanks name. You just killed the thread. I was waiting for 802.11 cooked my cat!

Name is errent on several points. Microwave's are a form of RF energy but at a much higher frequency than radio waves like the ones that your NIC card uses. The transformer side of the magnetron is emitting interference at a rate that IS the same as the frequency you card is using (and many other frequencies but all low ones) but is not microwave energy. The energy emitted from the transformer side is used to activate another device that emits microwave energy. If your microwave leaked as much energy as the transormer did you and everyone else around it would be suffering burns on a regular basis. The acceptable level for leakage is 1 milliwatt per square centimeter at 5 centimeters. In other words an INFINTISIMAL amount. It's not "blatently untrue" that they should not leak, it is absolutely true. Jimi_l

============================================ """Microwave's are a form of RF energy but at a much higher frequency than radio waves like the ones that your NIC card uses.""" ============================================= You are correct in the lowest, most basic form. The actual emmitted frequency IS NOT the same, but the point you missed, is that this energy is DIRTY, meaning that it has very poor spectral purity, and WILL IN FACT be full of "byproducts" known as "spurs" or "spurious emissions." This would be a situation (at lower frequencies) much like, say, your computer. Your computer does emit a small RF footprint at some frequency, along with harmonics and other mixed byproducts of this. This can be heard in a nearby radio at certain frequencies, and seen on a spectrum analyzer. Microwave ovens are exactly the same way, only worse, because they are a high power device, and a consumer "goods." ============================================ " The transformer side of the magnetron is emitting interference at a rate that IS the same as the frequency you card is using (and many other frequencies but all low ones) but is not microwave energy." ============================================= Really? What energy could this be? The TRANSFORMER operates at line frequency, 60hz in the U.S. and generates the high voltage to operate the magnetron. Of course, because of the nature of the AC switching components, SCR's Triacs, whatever else, the output IS DIRTY, but to claim that it is the same frequency as the wireless card is not correct. IT WILL however, generate some RF energy at unknown frequencies. This would be roughly the same class of noise as say, a motor commutator, say, in a vacuum cleaner, or "switching noise." ============================================ """The energy emitted from the transformer side is used to activate another device that emits microwave energy. If your microwave leaked as much energy as the transormer did you and everyone else around it would be suffering burns on a regular basis.""" ============================================ I don't know how you reached the above conclusion. The "transformer side" probably more properly known as the "high voltage power supply" doesn't emit much RF energy. It can cause some interferance to various radio equipment, but as a short wave, vhf, uhf listener, and someone who does some tech work on various radios and tranceivers, I can tell you that it 'ain't much. The fact of the matter is, that most any microwave I've had apart, maybe some 20 or so, were perfectly safe, so far as RF danger to humans, to operate with the top off, exposing the transformer and associated circuitry, and the magnetron. I can even show you at least on guy who claims to have worked in the microwave oven industry for years, testing them with the door open--something I won't do. ============================================ The acceptable level for leakage is 1 milliwatt per square centimeter at 5 centimeters. In other words an INFINTISIMAL amount. It's not "blatently untrue" that they should not leak, it is absolutely true. ============================================ I'll take your word for it here on the figures, the point I was making is you said that """A microwave should not leak at all...even a little is not acceptable.""" The FACT is that you just admitted they leak---up to whatever the official "limit" is. The fact is, that while this may be safe for human tissue, it still is SOME energy, not NONE as you claimed. THIS AMOUNT is certainly enough to cause interferance in sensitive communications receivers. I was first licensed as an amateur in the late 1960's. I spent six years in the U.S. Navy, maintaining GCA precision approach RADAR and other air navaids. I spent many years in the HVAC service industry, and the last few working years I installed communications site equipment for communications, paging, and telco.
