Title: Wireless cannot be detected, please help?
Post by: kelvin1997 on March 31, 2016, 01:24:36 am
Please take a look at my configurations and guide me if I have done anything wrong? I assume the hardware is working fine, my OPNSense box can see surrounding WIFI networks from "Interfaces->Wireless->Status", and my laptop can detect the surrounding WIFI networks, but my laptop can't see my OPNSense box. Here are my settings.

It can be a driver issue

Why did you use a public IP range for your wireless? Unless 20.1.1.1 is a typo?

https://tools.ietf.org/html/rfc1918 says 10/8, 172.16/12 or 192.168/16 for internal networks.

It could also be the chipset/driver as fabian suggested. Has this been tried with a FreeBSD 10.2 or did this work on the particular hardware before on OPNsense?

Want to ask you guys, what is the most commonly used inexpensive wireless card that works for OPNSense?

Could you tell me one or two commonly used models please?

@bartjsmit sorry should be 10.1.1.1, also tried 192.168.0.1

I have two of these TL-WN651G cards both worked on my two old win7 work stations before.
Thanks for your ref link. I am reading it.

An USB wireless stick was mentioned, also it is suggested to use an external AP for more an appropriate setup. But if possible I still like a PCI/PCI Express card.
