Issue explanation

After 2.5 years of working with Ubuntu, my wifi disconnects every 5 to 10 mins, and needs to be restarted to connect again. Recently it is connected but the data doesn't go through, and then when i reconnect it it works at top speed.

What I did

It has been asked here and here but no answer worked for me.

People seem to point to "switching off power management" but it doesn't seem to be right command

user@user:~$ sudo iwconfig ra0 power off
Error for wireless request "Set Power Management" (8B2C) :
SET failed on device wlan1 ; No such device.

Hardware

Please help. I own a hp pavillion g6 laptop (AMD A6 processor)

P.S

I posted a similar question, with no answers after 9 days. So I deleted it and posted again with better wordings better keywords and having spent more hours on it!
