All of a sudden, my Toshiba laptop won't make a wireless connection to my router. The router is a Motorola that I got when AT&T set me up with their U-Verse system. It's worked well up until now. Ran the troubleshooting program and it said to try an Ethernet cable direct hookup. That works well and keeps me online, but it doesn't solve the wireless connect problem. Ran the troubleshoot program again and it says that I have a "loose or broken cable detected". If that were so, then how come my smartphone and TV hook up and receive signals with no trouble? I've contacted AT&T tech support (yeah, big help there), and while I was talking to them, the wireless hooked up again and ran for a day before conking out again. At this point, I'm open to suggestions. Anybody??
