It used to be (when we first moved here almost two years ago) that my WLAN card could only see one network -- my own.

Then various DSL providers started offering free WLAN DSL routers, and they are multiplying like rabbits.

On my Airport WLAN submenu, I now see no less than six WLANs other than my own, and I frequently only see two out of four bars on the signal strength, even though I have interference robustness activated and the Airport Express router is in the same room. The laptops we have often barely get any signal at all if they aren't in the workroom. Used to be that I could work with the laptop on the balcony; now it can't even see the router unless I'm in the hall, maybe living room at best. If I want to work on the balcony again this summer, I may have to get another Airport router to boost the signal, thus adding to the overall problem.

Sheesh.
