see for example [here](http://ubuntuforums.org/showthread.php?t=2244010)). \r\n\r\nBut this is prima facie invisible to the user using this NIC, OS and driver, at least in my PC or PC-AC configuration.\r\nThat is:\r\n1. Enabling the relevant WMM/QoS settings in the AC caused the rate, as seen in e.g. a Nautilus copy/paste, to reach 802.11n levels. This got reflected in the AC connection status showing a 40MHz wide channel present. I THINK THAT THIS HAS TO BE EXPLICITLY STATED SOMEWHERE IN LINUX/UBUNTU/... and relevant sites/pages,  whatever the NIC and/or the driver thereof. Please add it for the sake of other people to the README.md.\r\n2. On the other hand, this is not reflected in the rate shown in the Connection Information of the Ubuntu Network Manager nor .e.g in the output of iwconfig. Moreover, trying to set the XXX in \"sudo iwconfig INTERFACE rate XXX\" to anything more than 54M causes the NIC and/or the driver to go crazy and revert to a 1M rate. THIS MAKES THINGS UNCERTAIN AND TROUBLING AND SEEMS LIKE A BUG; again at least with my system/network configuration, that is.\r\n\r\nPS On the txpower>20dBm issue I have to say \r\n1. MEA CULPA, APOLOGIES!\r\n2. I may try it out in the future; I'm presently satisfied with having solved or probably solved the n mode problem.\r\n3. More details: I hadn't tried to change the relevant regional settings. Had forgotten about this needed change -although unlike the WMM/QoS thing, instructions about it are readily available indeed-  whilst being overwhelmed by the n mode problem. \r\nI only first did a \"sudo iw reg set XX\", setting XX to my country's code after seeing the output of dmesg setting XX to CN when connecting a USB NIC I got my hands onto during the last days, to the laptop and whilst looking inter alia for a solution to n mode problem through comparison of the NICs and the settings thereof (btw: no modulation change possible for that NIC either). Though, and this is going even more offtopic, for the life of me, after reading [such stuff](https://wireless.wiki.kernel.org/en/developers/regulatory/crda)\r\n\"In order to achieve this devices always respect their programmed regulatory domain and a country code selection will only enhance regulatory restrictions\"\r\nI can't find where the \"correct\" wpa_supplicant file is located in the system so that the proper domain gets set ONCE at boot time without - the fear of - piling up regulatory restrictions..."}}
