Network Disconnects after resuming pc from suspend

Unfortunately I tried a lot of things like network manager restart command and installing r1689(some driver) and now after wakeup the icon shows detecting a network but still doesn’t connect.
Since I cannot attach the file being a new user, here is the info from the script you gave:
