Yesterday, quite suddenly my wifi connection started turning on and off. It most often happens after I have had the NC "sleeping". The only way I can apparently fix it is to shut it the NC down and restart. Has anyone else had this problem? BTW, I did do a search and did not find any mention of this particular issue. Strangely enough, it didn't start doing this until after I downloaded a tethering app to my DInc, but since I didn't have to make any changes to the NC, I don't see how that would be affecting the regular wifi connection. My regular home wifi connection had been very stable up to this point. The NC also did the same thing this morning when I brought it to work, where there is NO wifi connection at all. After I rebooted, I was able to tether to my DInc with no problems. Any ideas? Is there some particular setting I need to turn on/off on my NC? I'm currently running Nookie Froyo from the sd card.
