Wifi connectivity problem in Ubuntu 14.04

Question

Wifi is working properly on my laptop (hp-ab220tx) but when I suspend or close the laptop when it is working, now when I open it there I will lose the wifi connection. To get back the wifi connection all I need to do is restart the laptop.

Here are the network details:

Is this the same issue as asked here?http://askubuntu.com/questions/452826/wireless-networking-not-working-after-resume-in-ubuntu-14-04 — João Silva, Jul 20 '16 at 13:57

Have you turned the WiFi device off and then back on? This is often faster than a full reboot. There is usually a WiFi switch or button on HP Laptops. Use it to turn the WiFi off, then back on. This should restore its function (but is of course only a temporary solution). Also, could you provide us a more specific model number? HP shows no results on their website for an ab200tx, AB200tx, AB200Tx or AB200TX. Your model number is on the sticker at the bottom of your laptop, near the serial number and is usually labeled "p/n".
