My browser connection has become very slow. Pinging will show a very fast connection, but my browser response is often so slow that a request times out. Skype will work fine under these conditions, as well as my torrent agent.
I looked at 'syslog' and the output below seems to me related to the problem, but I don't have the expertise to have much more than a suspicion about it. If anyone could help me interpret the stuff relative to my browser problem, I'd very much appreciate it. my browser is iceweasel and i'm running Jessie. ====== Nov 23 21:37:03 t400-2 avahi-daemon[520]: Withdrawing address record for fe80::21e:65fffecd:2b64 on wlan0.
