Are you using pfSense Wireless? Tell us about your setup.



  • There are several people experiencing a significant amount of IN/OUT errors, slow wifi performance and/or disconnection on pfSense boxes.
    It is not clear if the issue is related to hardware, atheros driver or a combination of the two.
    It would be helpful for anybody willing to help, to share infromation about their setup. It is particularly important if you are not having any problem at all…
    In particular info about motherboard, memory, wireless card, wireless chipset, wireless mode (AP, Infrastructure, ad-hoc), type of problem (none, IN/OUT errors, slow wireless performance, disconnections, etc), athstats output would be helpful.

    Thanks in advance to everyone taking the time to share this information.

    I will give my setup as an example:

    Wireless Chipset:  Atheros AR2413
    Wireless Mode:    AP
    Problem:            IN/OUT errors, Slow perf., Disconnections
