Need new Wireless Router/Modem.

[Dmon]

Hey guys, so my TP-Link Modem has some serious security flaws and other problems and is in need of a replacement. I'm pretty new with networking so I need some suggestions for a good replacement for my TP-LINK TD-W8961ND

 

I live in Australia and have a ASDL2+ Connection so its not like it needs to be capable of ridiculous speeds but I want it to be at least on par with my current router. And it needs wireless capability due to the sheer number of PC's connected to it at any given time.

Is there a nice in between you would recommend for roughly ~$100-120?
