Hi,
I’m trying now using wireless network. My EeePC has BCM4313 adaptor.
When I try to install win7_64 driver with ndisgen it fails. It says “Unable to locate the kernel source tree. Set SYSDIR to override.”
I think, kernel source should be installed.
I’m able to use network with Android tethering. Is it worth to try install BCM4313 driver? Is there any other proper way to solve this problem?
Thanks.
It’s probably the easiest thing to get a cheap wireless USB dongle. I don’t know if ndis drivers are still supported in FreeBSD.
Can anyone suggest a mini USB WiFi dongle as brand and/or chip-set name that compatible with NomadBSD.
I’ve created a list with a small shell script:
#!/bin/sh
awk -F ' ' < /usr/local/share/usbids/usb.ids '
/^[0-9a-f]/ {
vendor = $1
}
/[Ww][Ll][Aa][Nn]/ || /[Ww][Ii][Ff][Ii]/ || /[Ww]ireless/ {
printf("%s:%s\n", vendor, $1)
}
' | xargs -I % /usr/local/libexec/dsbdriverd -c % | sort | uniq | grep if_
Output

I have a very cheap TP-Link TL-WN725N Nano USB WLAN Stick Adapter here which works with Nomad/FreeBSD.
You are great, thanks again.
Edit:
I bought a TP-Link TL-WN725N Nano USB WLAN Stick Adapter (Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter: if_rtwn_usb). NomadBSD uses it automatically.
