First off it doesn't work with the stock hostapd software, then it does not support any form of best channel selection (the "iwlist wlan0 scan cat /proc/net/rtl819xD/wlan0/best_channel" method advertised in Realtek's docs no longer works) nor on-the fly channel change, it is limited to 8 clients, and of course it is 2.4GHz only and its range is limited.īut I got it to run reliably at wifi-N speeds (my mac mini desktop client topped at 73Mbps), it is tiny and cheap. For anyone's interested, here is my recipe.īefore that I'd like to point I don't think this is the greatest adapter to choose as an AP. Then I found a version of hostapd that would work, but the AP would die overnight (adapter reversed to STA mode, hostapd process gone.) Finally I have found a setup that seems solid. When I put it in, it was recognized ok but I could not get hostapd to work with it. The thing says "Ideal for Raspberry Pi" on the tin. I got an Edimax EW-7811Un USB nano wireless adapter in order to add a short-range AP to a Pi2.
