Hello everyone. I solved my problem as follows:
For the wifi working after hibernate or suspend, I applied the solution given by Wolfgang Kufner in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/689004 (specifically the solution described in comment # 9) With this solution: sudo touch /etc/pm/power.d/pcie_aspm I got my wifi back to wake up from suspend or hibernate. On the other side and even when turned on, the wifi connection I was sometimes very slow or even freeze. In this case I applied a similar solution to that given in http://ubuntuforums.org/showpost.php?p=10829039&postcount=10 In my case, when I run iwconfig I found that my wireless device (wlan0) is RALINK RT2860STA. However, when I ran lsmod I saw loaded rt2800, rt2x00pci, rt2860 and similars modules in addition to or instead of rt2860sta. To prevent this I added the following lines in /etc/modprobe.d/blacklist.conf: blacklist rt2800pci blacklist rt2x00pci blacklist rt2860 and now only loads the driver/module 2860sta and my wifi connection (for my device RALINK RT2860STA) works now without any problems.
