answer:Have you tried shutting off the wi-fi on your laptop completely once and then re-starting? When I’ve been switching between lots of different wi-fi networks I find that occasionally my “detect wireless networks” will fail to see the network I want it to see.. and the only way to get it to work again is to flip off my wi-fi switch (I have one on the laptop—a physical switch to turn off the wi-fi) and then after a re-boot I flip it back on. THEN it will see the correct available wireless networks..and at the correct strengths.. But..then, this is just my case, and with my Dell notebook. Your mileage may vary..
