Wifi - wrong speed reported

Morris, when you catch some time, would you mind to run a couple iperf tests with DWA-192, to see real network throughput results. I can't run any at the moment because Fedora is refusing to actually use the device at all. I have also just upgraded to F25 and nothing has changed. The last time I used this device was on 08/10/2016 and it was using the ATH9K driver. The main reason I upgraded to this USB device was that I upgraded my router to a faster version, and I found that unlike the DWA182 I didn't have to compile my own driver, the kernel had inbuilt support for the DWA192. It is possible that I have managed to Blacklist the device in some way, not by the conventional Blacklist.conf, and I have forgotten how so I can't find where I've done it to reverse it. Also, having never done it before, I also don't know how to run iperf tests. regards, Steve Did I understand you correctly, what you're saying here is that: D-Link DWA-192 - Realtek RTL8814AU Wi

The issue is probably deeper than that If you use dnf --best update sagemath you'll see a problem with Singular which requires polymake but root@f24 ~]# dnf --best install polymake Last metadata expiration check: 1:29:04 ago on Tue Jan 24 08:41:34 2017.

The package needs to be rebuilt with the latest perl as a dependency. You could open a bugzilla requesting this. You could uninstall sagemath, update, download the sagemath src.rpm, and build it with the new perl, and then re-install it as a workaround. The ticket is probably easier. ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org
