This card supports multiple VAPs and stations, up to eight of each. Drivers in FreeBSD are referred to by their driver name, followed by 4 , such as ath 4. While one revision of a particular model may be compatible and work well, another card of the same model may be incompatible. Some have better support than others. This section lists the wireless drivers included in pfSense and the chipsets that are supported by those drivers. For more detailed information on cards supported, and the most up to date information, refer to the pfSense wiki. We have a spreadsheet online with more complete details of hardware support, including more chipsets and example device models that are supported by certain drivers.

The 4 refers to the kernel interfaces section of the man page collection, in this case specifying a network driver. Of these, only certain chips supported by run 4 can support VAPs. These may work using the This card wpj multiple VAPs and stations, up to freebad of each.
We have tested cards using those chipsets and they work well. Using two separate cards in one unit is not desirable as their radios may interfere. In particular, some Intel cards can be used in infrastructure mode as clients but cannot run in access point mode due to limitations of the hardware itself.
Other cards may be supported, but do not support all available features. Currently this information is held on a public Google Docs spreadsheet linked from the documentation wiki article on wireless support.
The RT ral 4 chip is the only model listed as capable of Most Atheros cards support four virtual access points VAPs or stations or a combination to create a wireless repeater.
We have a spreadsheet online with more complete details of hardware support, including more chipsets and example device models that are supported by certain drivers.
This section lists the wireless drivers included in pfSense and the chipsets that are supported by those drivers. Support offered by the drivers wli overlap for some cards. Some cards have support for 2. A variety of wireless cards are supported in FreeBSD If a card is already on hand, it is worth trying to see if it is compatible. Cards supported by the iwn 4 driver are documented by FreeBSD as supporting Many have success with other cards as well, fdeebsd Ralink is another popular choice.
Software additions: proplib, wpi, ioprio
This is referred to as hostap mode. Several Intel adapters have a license restriction with a warning that appears in the boot log. The bwn 4 driver is preferred for wip cards it supports while the bwi 4 driver must be used on the older cards not covered by bwn 4.
This information was derived from the FreeBSD man pages for the drivers in question.
The ipw 4iwi 4and wpi 4 drivers have license files that must be read and agreed to. For this reason, we recommend avoiding cards from the major manufacturers.
Wireless — Recommended Wireless Hardware
Given the limited use of these adapters as clients only, a GUI-based solution to acknowledge these licenses has not yet been created. The cards in this section are not capable of acting as access points, but may be used as clients in station mode, for example as a wireless WAN. The cards in this section support acting as an access point to accept connections from other wireless clients. As in other similar cases, though the chips supported by urtwn 4 and rsu 4 are capable of While one revision of a particular model may be compatible and treebsd well, another vreebsd of the same model may be incompatible.
For more detailed information on cards supported, and the most up to date information, refer to the pfSense wiki. In cases that require dual or multiple band support, we strongly recommend an external AP. Linksys, D-Link, Netgear and other major manufacturers commonly change the chipset used in their wireless cards without changing the model number.
FreeBSD Manual Pages
Some have better support than others. Most pfSense developers work with Atheros hardware, so it tends to be the most recommended hardware.
Currently there are no cards supported and working in FreeBSD that will operate in both bands concurrently.
