Thanks Rick and Steve. I was just curious as to whether my new laptop could get the claimed speeds over wifi. I too have gigabit ethernet around the house and plug into that normally. As far as I can tell 802.11ac still has little support on open-source / linux-based routers, so I'll hold off upgrading my router. Besides, 'ac probably has the same 2x overstatement of advertised speed vs actual measured speed. ;-) -wolfgang -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

These are a good idea when you don't want some random charger at a coffee shop or airport to download all your pictures and other data while your phone is charging. -wolfgang -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

My OpenWRT AP has a status page that claims that the 5 Ghz radio is configured for a 150 Mbits/sec 40Mhz (double-wide) channel. I'm only seeing a 54 Mbit/sec throughput over WIFI though. (Over ethernet to the same router I'm seeing the expected 180 Mbits/sec to the internet.) This is what lshw(1) has to say about the wifi card: *-network description: Wireless interface product: RTL8821AE 802.11ac PCIe Wireless Network Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@:03:00.0 logical name: wlp3s0 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rtl8821ae driverversion=4.2.8-300.fc23.x86_64 firmware=N/A ip=192.168.75.107 latency=0 link=yes multicast=yes wireless=IEEE 802.11abgn resources: irq:52 ioport:3000(size=256) memory:b200-b2003fff Does this ring any bells? I can easily believe that the faster speeds are proprietary extensions but figured I'd check. AFAIK, 802.11n has a theoretical limit of 160Mbps. However, that's over that full, 40MHz double-wide channel with no channel contention and no other radios active. The radio on your AP is shared among all users of the AP so you have to take that into account. The theoretical limits of the radio are probably only approached in a lab environment for any wifi technology. The real world is, well, different. :-) If you want higher speeds, then 802.11ac is a better route. Note that it only works over the 5GHz radio (not the 2.4GHz that 802.11n can use), so it doesn't have the range or "penetration power" (ability to go through walls, etc.) that the 2.4GHz band has. None the less, it is faster (theoretically over 8 times faster than 802.11n due to a number of additional things done in the protocol, muxing, antenna handling and session management). Just one point on this, I have a Belkin 1750 ac modem/router that has 2 usually used SSID's, one that runs only over the 2.4GHz band and one that runs over the 2.4GHz band and the 5GHz band as documented (I'm also being told that ac gets its faster throughput because it does use the 2.4 GHz and 5GHz bands at the same time). The issue I have found is that with the 2.4GHz mode I lose about 200 KiloBytes/sec download over the 802.11n modem/router I replaced, and, the mode that uses both bands doesn't change that but that mode is notoriously unreliable for playing online games. I'm also using a usb wireless card on my pc to get the ac compatibility, but I need to compile the driver every time the kernel changes because it has a chipset in it that is not supported by Fedora, and I'm told it never will be. These are just things that need to be considered when evaluating whether or not to swap from 802.11n to 802.11ac, you may also want to consider whether or not you want/have a need to change to the 802.11 protocols beyond 802.11ac as well. regards, Steve As always, YMMV.

NUT config for Powercool UPS

Google hasn't returned anything useful. I've checked (too late) the hardware compatibility list and it's not on, but there are sections on generic USB connections but I can't seem to make any progress with this.
