It is still true that unless you have a very late model AP, If you have any single 802.11G device on an 809.11N capable AP, don't be surprised if many stations get dragged down to G speed or lower.
Not quite. B causes a significant performance hit to G & N. This was because G and N use a different modulation type than B. This meant that when they detected a B signal, they'd have to drop into compatibility mode, where they had to transmit in B a packet to reserve the channel for the time it takes to send the G or N packet and then transmit the G or N packet. On the other hand, since G & N use the same type of modulation, only the N header has to be transmitted at G spec and then the rest of the packet can transmit at N speed. Similar happens on 5 GHz, with A, N & AC. They all use the same modulation method and just have to slow down the header to accommodate the lower speed devices. That said, there's no point in configuring the access point to allow any slower than you need. So, if you have no G devices, then don't configure the access point to allow them. Hopefully there's no B devices left in your area. Since N came out about 5 years ago, there's not a lot of devices around that can't do it. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
