Thanks for those suggestions, but besides some cell-phones (not near laptor or accesspoint) we don't have any wireless (radio) devices, and the microwave oven is meters away and inactive at most of the times of my tests. I'll look at the burst rate and give it a try. I tried at least five different locations in the house but except for one these were on or in open wooden closets, next to a wall. The other one was on the table max. 1 meter away from my laptop. I'll try on a different table farther away.
How high is your router/access point located?
In our computer room we had the router on a cabinet up right at the ceiling. Getting a connection on our laptop on a TV tray right below it was nearly impossible. Move to the other room and it connected just fine. Lowered the router and end of problem.
Just a thought.
Every now and then, I have read a few of the responses on this discussion. I just have a few comments. You definitely do not want two wireless devices communicating on the same channel too close together. Even nearby channels can cause the transmitter to overload the receiver circuit. While the symptom is data distortion, we are talking about a potential damage to the receiver circuit. Good receivers would simply shunt the signal to prevent damage. With low power devices, antennas become extremely important. At the frequency of wireless devices, polarization can make a several db difference in signal strength. In other words, all antennas should be horizontal or vertical. Vertical orientation usually give the best horizontal coverage, but will have blind spots of the ends of the antenna. Just think of a doughnut being placed over the antenna. You can then easily visualize the radiation pattern. I personally miss the PCMCIA cards that allowed the antenna to be vertically polarized. To overcome this shortcoming, I wrap the cardboard core of a toilet paper role with tinfoil, and set stand it next to the wifi antenna. It does give a small signal boost, because the tube is almost a perfect 1/4 wave length antenna. If I really want distance, I use a wireless card that has an external antenna. There are some really cool external antennas that provide significant signal gain. Just in case you are wondering, I am an amateur radio operator. Playing with radio signals is second nature.
