| + | * For [[en/developers/Documentation/Glossary#fullmac|FullMAC]] devices support see [[en/users/Drivers/brcm80211|brcmfmac]] and [[en/users/Drivers/rndis_wlan|rndis_wlan]] | ||

| + | ===== Known problems & limitations ===== | ||
| + | |||
| + | * Some stalls (on G-PHY only?) possibly related to CCK vs. OFDM, see [[https://lists.openwrt.org/pipermail/openwrt-devel/2012-August/016432.html|WRT54g / b43 / mac802.11 BREAKTHROUGH]] | ||
| + | * N-PHY: 5 GHz support requires kernel 3.17+ | ||
| + | * HT-PHY: no support for 5 GHz | ||
| + | * No support for 802.11n features (HT, aggregation, 40 MHz width) | ||
| + | |||
| + | ===== Resolved problems ===== | ||
| + | |||
| + | * G-PHY devices: not working with kernels 3.15 and 3.16-rc1 (a regression). This was fixed in 3.15.5 ([[https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-3.15.y&id=6f3f164bd0efe9a090cd74e08d6195c95024a1d1|6f3f164]]) and 3.16-rc3 ([[http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2fc68eb122c7ea6cd5be1fe7d6650c0beb2f4f40|2fc68eb]]). | ||
| + | * Scanning/connectivity problems: caused by **b43** bug exposed with kernel 3.8 (by [[http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0172bb75073e11a5aa9d8a953bdaefb8709f00c8|0172bb7]]). Fixed in kernel 3.14 (by [[http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=64e5acb09ca6b50c97299cff9ef51299470b29f2|64e5acb]]) and backported to 3.13.2, 3.12.10, 3.10.29. | ||
