Intel pro 5100 AGN wireless connection problem
By John Parsons •
Hello ladies and centlemen. I recently grow an interest about Ubuntu OS. I was trying to use Lubuntu 3.16.0-31-generic(i686) on my old notebook HP Pavillon dv6. I succesfully manage to boot it. However, now i have a wierd wifi connection problem. It detects but doesn't connect my wi-fi at home, even though it connects my phone's wi-fi hot spot. It also can connect via cable. I searched all the forum and tried a few tricks but they didn't solve the issue. Here are some information;

Change your wifi routers security settings to WPA2 only and reboot router and it should work better
