I've discussed my wireless needs on the list before - I'm thinking that the best solution would just be to buy a device that will take OpenWRT and serve as an 802.11n access point.
My network configuration:
Desktop Linux workstation with ADSL PCI card installed, also running DHCP, Bind, Postfix and radvd for IPv6 - native IPv4/IPv6 dual-stack connection to Internode and a static Ipv4 address. FreeSWITCH (for VoIP) is running directly on this machine so it isn't behind NAT.
Gigabit switch -> printer, SIP phone, laptop on local LAN.
Now I want to add 802.11 wireless for phones, tablets, etc., both IPv4 and IPv6. Given previous discussions and my research, I'm considering just buying a device that will take OpenWRT, attaching it to the Gigabit switch and either bridging the wired and wireless networks or routing the packets between separate networks.
Hardware suggestions would be welcome, as would any alternative ideas on how best to proceed with this. One option would be the devices that the Buffer Bloat project is recommending - all of the drivers are open.
I've been pretty happy with openwrt on the Netgear WNDR3800. It has dual band wireless (2.4 + 5), 4 x gigabit ports, or 5 if you don't need the WAN port, and seems to be able to move data between them pretty quickly. And plenty of flash and memory - I've run squid on one before (filtering proxy only - no cache). OpenWRT can set up the multiple SSID's easily too via the GUI. It should be able to run the sip proxy stuff too, if you wanted to route instead of bridge. James
