that the best solution would just be to buy a device that will take
OpenWRT and serve as an 802.11n access point.
here are two more alternative methods to consider, both involving use of
the hostapd package.
1. buy a USB/PCI/PCI-e wireless NIC and install it in your current
you already have dhcp, dns, iptables, and everything else configured and
running, so you only need to configure hostapd.
be careful when selecting a NIC, not all will work in Master aka AP
or Access Point mode - although it's not uncommon for 802.11a/b/g.
unfortunately, very few 802.11n NIC drivers support master mode in
linux. NICs based on the ath9k chip seem to be the best bet for
802.11n. The brcmsmac driver also got AP mode support in March this
2. get a cheap old laptop with built-in wireless NIC. Again, make sure
that the NIC supports Master mode under linux. Configure hostapd. if
you use a separate IP subnet for the wireless LAN, you may also need to
run a dhcp relay so that bootp packets get forwarded between the wlan
and your dhcp server (alternatively, just run another dhcp server on the
laptop, listening only on the wlan interface so it doesn't conflict with
your main dhcp server)
I use an old eeepc 701 for this job at home. the wifi chip in it only
supports 802.11b and 802.11g, but it's adequate for my needs. if/when
i need better/faster than that, i'll probably get a wifi nic for my
gateway machine and retire the eeepc.
there's an iphone, an android phone, two android tablets, a linux
laptop that connect regularly to this, and occasionally other machines
(including mac and windows laptops). I have it configured so that each
machine that connects has a separate login and password, and dhcpd
assigns each one a static IP addresses.

Description-en: user space IEEE 802.11 AP and IEEE 802.1X/WPA/WPA2/EAP Authenticator
Originally, hostapd was an optional user space component for Host AP
driver. It adds more features to the basic IEEE 802.11 management
included in the kernel driver: using external RADIUS authentication
server for MAC address based access control, IEEE 802.1X Authenticator
and dynamic WEP keying, RADIUS accounting, WPA/WPA2 (IEEE 802.11i/RSN)
Authenticator and dynamic TKIP/CCMP keying.
The current version includes support for other drivers, an integrated
EAP authenticator (i.e., allow full authentication without requiring
an external RADIUS authentication server), and RADIUS authentication
server for EAP authentication.
hostapd works with the following drivers:
* mac80211 based drivers with support for master mode [linux]
* Host AP driver for Prism2/2.5/3 [linux]
* Driver interface for FreeBSD net80211 layer [kfreebsd]
* Any wired Ethernet driver for wired IEEE 802.1X authentication.
