    Orange Pi Zero wireless AP

    in Orange Pi Zero

    Thanks gentlemen for the recommendations, but if I bought all that to make it work, I might as well buy an RPi.

     

    The thing is, the OPi0 has exactly the hardware I need for my application: 1 USB port, 512MB+ RAM, onboard wifi, an additional NIC (wireless would be great, but wired will work too), microSD memory, capable of running linux (LAMP server).

     

    If it were a one-off project, I'd be all for buying the nicer SBC (I've built my project on 3 different RPi versions and have at least 10 RPi's) or buying the accessories to make it work (that's something else I've done before), but I'm looking to mass produce my device for commercial sales and where I don't have the capital to develop my own board, I'm using off the shelf hardware. I like this board because it gets rid of the extras that cause my customers confusion (HDMI, SPDIF, 4xUSB) and it brings down my costs.

     

    Do you guys have any recommendations for a different SBC that meets my minimum requirements, but costs less than the RPi3? Or a good resource that lists lots of SBCs and let's me search/filter for my needs?

     

    As it is, the OPi0 works adequately, but the wifi isn't very fast or reliable, so I'm looking to solve that problem or find another solution.

    Thanks for your efforts on this! I'm hoping, like everyone else, for a better wifi driver.

     

    I'd love to help, but my skillset doesn't run that deep, unfortunately.

     

    I'm pretty ignorant to how this all works, but from what I read, the H2+ in the OPi Zero is about the same as the H3. If that's the case, would this datasheet for the H3 give you what you need?

    I'm super motivated to get the OPi Zero wifi working a bit better, as it's the perfect hardware (exact features) I need for my project. If there's anything I can do (my knowledge goes as deep as setting up a Linux web server and setting HostAPD and other application settings), please let me know. I'm happy to test, research, search and tinker.

     

    @carabennemsi, 

     

    I have a lot of performance issues the wifi of the opi zero, too. With the armbian debian release I have experienced an average download speed of 1MBit/s. Get's a bitt better if I get closer to the AP. 

    The nightly build of ubuntu performance slightly better for me, but still not very useful for any application using wifi.

     

    I had that same problem at first (1Mbps speeds), but got my speeds up to 5-6Mbps @ 3 meters and 8-10Mps @ 1 meter through tinkering with settings and configurations... I didn't do the best job documenting what worked, but I think it was in my HostAPD settings, which you can find in this thread: https://forum.armbian.com/index.php/topic/3414-orange-pi-zero-wireless-ap/#entry24370

    I've set up my new OPi Zero as a wireless AP running the latest Armbian build for the OPi0. It's working mostly great. My one problem I'm having is that my speeds seem to be throttled to 5-6Mbps. I connect wirelessly from my phone and run a speed test and get 5-6Mbps. If I connect directly to my router, I get 30Mbps.

     

    I have a Rpi3 set up about the same as the OPi0, and when I connect it up I get the full 30. Each time I've tested with the OPi and RPi, my phone is the only device connected.

     

    So, I've poked around online and I can't seem to figure out if it's a hardware limitation or if it's a software/driver/setting limitation. Also, if it's the latter, how/where to find the problem in my configuration.

     

    Has anyone else gotten better speeds out of their OPi0, if so, what were they? Does anyone have any recommendations for where to look to configuration changes?

     

    This is my current HostAPD configuration:

     

    # This is the name of the WiFi interface we configured above

    interface=wlan0

     

    # Use the nl80211 driver with the brcmfmac driver

    driver=nl80211

     

    # This is the name of the network

    ssid=babyRoadTrip

     

    # Use the 2.4GHz band

    hw_mode=g

     

    # Use channel 6

    channel=6

     

    # Enable 802.11n

    ieee80211n=1

     

    # Enable WMM

    wmm_enabled=1

     

    # Enable 40MHz channels with 20ns guard interval

    ht_capab=[HT40]

    # Not sure if OPi supports these:

    # [sHORT-GI-20][DSSS_CCK-40]

     

    # Accept all MAC addresses

    macaddr_acl=0

     

    # Use WPA authentication

    auth_algs=3

     

    # Require clients to know the network name

    ignore_broadcast_ssid=0

     

    # Use WPA2

    wpa=2

     

    # Use a pre-shared key

    wpa_key_mgmt=WPA-PSK

     

    # The network passphrase

    wpa_passphrase=roadtrip

     

    # Use AES, instead of TKIP

    rsn_pairwise=CCMP
