You have acquired a problem on your computer with actually allowing wireless network communication with your printer.
Try disabling the AVG firewall temporarily when installing the printer's drivers over again - a long process, but necessary, otherwise you will get the
Check network and try again
error, probably caused by the efficient and excellent performance of AVG's firewall (when it is active). If AVG firewall is disabled, but you still get a Check Network And Try Again error, then your computer's network functions are disabled and corrupted enough to make wireless printing impossible, probably owing to the acquisition of virus or malware infection owing to having insufficient security software on the computer previously.
There are two possible treatments in practice as I see it at present:
1. use a USB connection instead.
2. re-install Windows on your computer from scratch, after backing up all data on the computer that is of value to you onto a separate device, for instance a flash drive.
Let me know what you think, whether you see other possible paths to take, etc.
