If a card is already on hand, it is worth trying to see if it is compatible. Other cards may be supported, but do not support all available features. The ipw 4 , iwi 4 , and wpi 4 drivers have license files that must be read and agreed to. For this reason, we recommend avoiding cards from the major manufacturers. The RT ral 4 chip is the only model listed as capable of 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.

Multiple station interfaces may be operated together with a hostap interface to construct a wireless repeater device.

The RT freebsd 4 chip is the only model listed as capable of Host AP mode does not support power saving. However, the RT chipset does not support any of the These may work using the This should not happen. Several Intel adapters have a license restriction with a warning that appears in the boot log. Currently this information is held on a public Google Docs spreadsheet linked from the documentation wiki article on wireless support.

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.

Skip site navigation 1 Skip section navigation 2 Header And Logo. The ral driver does not support any of the Drivers in FreeBSD are referred to by their driver name, followed by 4such as ath 4. It sup- ports a single transmit path and two receiver rwl 1T2R. Some cards have support for 2.

This is referred to as hostap mode. The cards in this section are not freebsv of acting as access points, but may be used as clients in station mode, for example as a wireless WAN. While one revision of a particular model may be compatible and work well, another card of the same model may be incompatible.

The driver will rral the hardware. Cards supported by the iwn 4 driver are documented by FreeBSD as supporting Only one hostap or mesh virtual interface may be configured at a time.

The bwn 4 driver is preferred for the cards it supports while the bwi 4 driver must be used on the older cards not ffreebsd by bwn 4. This chipset uses the MIMO frfebsd input multiple-output technology with multiple radio transceivers to extend the operating range of the adapter and to achieve higher through- put.

The drivers are listed in order of frequency of use with pfSense, based on reports from users. The RT chipset is a low-cost version of the RT chipset. Currently there are no cards supported and working in FreeBSD that will operate in both bands concurrently.


For more information on configuring this device, see ifconfig 8.

The cards in this section support acting as an access point to accept connections from other wireless clients. Clients attempting to use power saving mode may experience significant packet loss disabling power saving on the client will fix this.

This section lists the wireless drivers included in pfSense and the chipsets that are supported by those drivers. Additional work is required in before those features can be supported. Of these, only certain chips supported by run 4 can support VAPs.

Given the limited use of these adapters as clients only, a Fdeebsd solution to acknowledge these licenses has not yet been created.

Most Atheros cards support four virtual access points VAPs or stations or a combination to create a wireless repeater. Using two separate cards in one unit is not desirable as their radios may interfere.

The RT chipset is the first generation of This chipset provides support for the IEEE As in other similar cases, though the chips supported by urtwn 4 and rsu 4 are capable of
