Raspberry Pi Wireless AccessPoint issue with WiPi Dongle

pbhound
pbhound over 9 years ago

Hello all, I need assistance with an issue.

 

I am trying to configure my Pi as a Wireless Access Point (WAP).

I have it all configured according to the Adafruit Guide https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point/overview

 

When I run "sudo /usr/sbin/hostapd /etc/hostapd/hostapd.conf"

 

I get the following error:

     Configuration file: /etc/hostapd/hostapd.conf

     Line 4: unknown hw_mode "N"

     1 errors found in configuration file '/etc/hostapd/hostapd.conf'

 

the content of my hostapd.conf file is such:

    

     interface=wlan0

     driver=rt2870

     ssid=Pi_AP

     hw_mode=N

     channel=6

     macaddr_acl=0

     auth_algs=1

     ignore_broadcast_ssid=0

     wpa=2

     wpa_passphrase=Raspberry

     wpa_keymgmt=WPA-PSK

     wpa_pairwise=TKIP

     rsn_pairwise=CCMP

 

I have tried it with "g" and with "n" and get the same error (with "g" and "n" respectively)

 

If I comment out "hw_mode=N" I get the following error

 

     configuration file : /etc/hostapd/hostapd.conf

     dry->ifindex=3

     l2_sock_recv==l2_sockxmit=0x0f3e638

     IOCtl[SIOCSIWMODE]:invalid arugment

     could not set interface mode(3)!

     could not set interface to master mode!

     rtl871xdrv driver initialization failied.

 

My wireless adapter is from element 14 https://www.element14.com/community/docs/DOC-69361/l/wifi-usb-dongle-for-raspberry-pi#cblogposts

I have the drivers for the device placed It into the /bin folder.

 

any and all help will be greatly appreciated

 

Thank you

    Please see the following. It would help if you give the output of lsusb command to see the chip set.

     

    Please make sure you Wifi dongle supports Access Point or Master Mode

    • Edimax doesn't support Access Point (UPDATE 8/22/15: Edimax DOES support Access point, hostapd 2.4 with rtl driver: Hostapd-rtl8188)
    • AirLink 101 / AWL5088 doesn't support Access Point
    • Panda Ultra, Mid-Range and 300Mbps Wireless N Adapters support Access Point
    • Ralink RT5370 supports Access Point

    This is what the lsusb gets me. so I take it that the driver that I need is the rt5370?
