I apologize, this is duplicately posted. I forgot if I hit the submit button in the Mavericks forum and this is a double post. I can't delete it, so I beg the moderators forgiveness and ask them to please delete this dupe -- it was unintentional.
I have a TL-WDN4800 b TP-Link, which worked fine under Mountain Lion, but drops connection randomly under Mavericks. No errors appear in Console, and the WiFi indicator in the status bar still shows that I am connected, but I can't access websites or even the router's admin screen. If I turn off Wifi and re-enable it it will work fine again for an undetermined amount of time.
Has anyone else experienced this?
