Ever since whenever someone I know is about to buy an ASUS router I make sure to warn them and tell them to at least making sure to run the latest firmware if they go through with the purchase. As for my mother I brought over an old C2D-box which I hooked up with a couple of old Intel Pro Server GBE-nics, configured a NetBSD firewall+nat and reconfigured her router to act as a* dumb access point.
*Should I use an here since the object it is acting upon is started with a vowel or should I let the adjective rule the indefinite article? English isn't my first nor second language and I always struggle with these things so I appreciate any guidance.
