The mask for an 80 MHz channel is an extension of the 40 MHz mask. A 40 MHz channel causes more adjacent channel interference (ACI) than a 20 MHz channel, while an 80 MHz channel is expected to cause more than a 40 MHz channel. In 802.11n deployments it is common to configure adjacent APs on non-adjacent channels, which means adjacent APs 802.11ac devices are required to support 20 MHz, 40 MHz, and 80 MHz operation. This field is used to indicate support for 160 MHz operation. It takes on the value 0 if there is no 160 MHz support, the value 1 if the transmitter supports 160 MHz contiguous operation only, and the value 2 if it supports both 160 MHz contiguous operation and 80+80 This will force it to use 40 MHz width. This is generally not recommended if you have many other networks that operate at 20 MHz in your area. For the 5 GHz band, you can force 160 MHz width by going to Advanced -> Advanced Setup -> Wireless Setup. Routing: NETGEAR RAX43 - Firmware: v1.0.15.128 (1 Gbps down, 40 Mbps up) A narrower channel has a higher signal-to-noise (SNR) ratio than a wider one. You lose 3dB of SNR every time you double the channel width. This is mostly irrelevant when you're in range (good SNR). But it will make a difference at the edge of coverage where your connection quality is limited by the SNR. In our example from 5530 we subtract 20MHz once, which gives us value 5510MHz, and to 5550 we add twice 20MHz (+40MHz) which gives us value 5590MHz. The obtained values are the initial value of the channel frequency equal to 5510MHz and the final value of the channel frequency equal to 5590MHz (5510MHz-5590MHz). Interesting. I run a 40 MHz wide "only" 2.4 GHz network (done it with my 68U and my AC3100), and I have several connected Apple devices. Your comment suggests that my 2.4 GHz network should be stepping down to 20 MHz width, but all the wifi snoopers show the network as still being 40 MHz wide. There's no 20Mhz on 5Ghz ac and the link/PHY on 40Mhz should be no higher than 400Mbps. You're right though, 80Mhz will produce a large stutter but it's completely the Quests fault, not Virtual Desktop's. Going by what you're saying, if you haven't dedicated a 5Ghz band with a unique SSID to your Quest, it may help. TellitToTheJudge. La maggior parte dei router e dei dispositivi WiFi determinerà automaticamente se usare canali da 20Mhz o da 40Mhz a seconda dei canali disponibili, dei protocolli supportati dal client e dal punto di accesso, e del livello di interferenza. Ma i sistemi più sofisticati possono permetterti di ignorare le impostazioni automatiche. Aae9.
