@Jose Carlos Marti Hi, I am sure you are correct regarding the theory, and high frequencies, HOWEVER, I think most of the posters wit this issue are finding that the WiFi module was working FINE for a while from new, and then gradually gets worse, or fails after a software update. I assume that to take the folds out of the cable, you have to disconnect it, then plug it back in. That will have the effect of cleaning the plug and socket contacts, and there are some technical posts on other forums that state that the connection plug/socket can get dust ingress, and contact resistance build-up. Removing and plugging back in will "wipe" the contacts clean and restore the connections to a working state in many cases (from what I read elsewhere).
