Assumption: Maybe either still some power management issue -even if it seems to be successfully turned off- or some mixup with the USB stack. Reproducible: Always Steps to Reproduce: 1.ping -c 1000 -A fritz.box 2.-wait some time- 3.ping -c 1000 -A fritz.box RTT increases, package loss increases. INFO: This never happened before, this still does not happen in Windows 7. Therefore I think, hardware is ok. Actual Results: Sometimes -after a while- web pages can be loaded better again. For instance, URL "www.focus.de" can be accessed without problems right after startup, then attempting to access the URL results in empty pages ("connection broken"). It seems, that things get worse, if an additional WLAN device (laptop) uses the router. Expected Results: Expected Result: Same network stability as in OS 12.3 (I had to turn off power management there, too; the device name used to be "wlan0" back then.) I reconfigured the connections and tried to identify a DNS problem. The configuration of "eth0" has no effect on the problem. DNS is correctly configured, too.
