Let's say I have plan to upgrade to unifi once it is available.. Mean while stucked with streamyx..

I need a better wireless router to extend my wireless range which would also be still usable when I upgrade to Unifi.

Looks like my choice would be limited to
1) TP-Link TD-W8960N
2) Asus RT-N13U

From the choice clearly shows that I have limited budget, my aim is to maximise transfer speed and wireless coverage between my computers.. Wirelessly..

Seems that TD-W8960 have rather weak wireless transfer speed
