The 4 refers to the kernel interfaces section of the man page collection, in this case specifying a network driver. We have tested cards using those chipsets and they work well. Currently there are no cards supported and working in FreeBSD that will operate in both bands concurrently. Support offered by the drivers does overlap for some cards. Drivers in FreeBSD are referred to by their driver name, followed by 4 , such as ath 4.

For this reason, we recommend avoiding cards from the major manufacturers. This chipset uses the MIMO multiple- input multiple-output technology with multiple radio transceivers to extend the operating range of the adapter and to achieve higher through- put. Many have success with other cards as well, and Ralink is another popular choice. This information was derived from the FreeBSD man pages for the drivers in question. Linksys, D-Link, Netgear and other major manufacturers commonly change the chipset used in their wireless cards without changing the model number.
Wireless — Recommended Wireless Hardware
Drivers in FreeBSD are referred to by their driver name, followed by 4such as ath 4. The drivers are listed in order of frequency of use with pfSense, based on reports from users.
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 bwn 4 driver is preferred for the cards it supports while the bwi 4 driver must be used on the older cards not covered by bwn 4. The ral driver does not support any of the Any number of wds virtual interfaces may be configured together with a hostap interface.
Check the board’s PCI version before purchasing the card as it is likely these adapters will not work in systems based on older revi- sions of the PCI specification.
freebsd This section lists the wireless drivers included in pfSense and the chipsets that are supported by those drivers.
Host AP mode does not support power saving. As in other similar cases, though the chips supported by urtwn 4 and rsu 4 are capable of The RT chipset is the first generation of single-chip Most pfSense developers work with Atheros hardware, so it tends to be the most recommended hardware. The transmit speed is user-selectable or can be adapted automatically by the driver depending on the number of hardware transmission retries.
Clients attempting to use power saving mode may experience significant freebwd loss disabling power saving on the client will fix this.

Additional work is required in before those features can be supported. The RT chipset is a low-cost version of the RT chipset. 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. While one revision of a particular model may be compatible and work well, another card of the same model may be incompatible. This is referred to as hostap mode.
Currently there are no cards supported and working in FreeBSD that will operate in both bands concurrently. Currently this information is held on a public Google Docs spreadsheet linked from the documentation wiki article on wireless support. In cases that require dual or multiple band support, we strongly recommend an external AP. The 4 refers to the kernel interfaces section of the man page collection, in gal case specifying a network driver.

The RTE chipset is freebzd single-chip This card supports multiple VAPs and stations, up to eight of each. This chipset provides support for the IEEE However, the RT chipset does not support any of the Using two separate cards in one unit is not desirable as their radios may interfere.
The RT chipset is the second generation of
