Revision history [back]

Recently I have had to re-enter the password to my home WLAN several times a day. At first I thought this was a bug in the latest update, but today I remembered that I made another change recently. I changed the WLAN router from using a fixed channel to automatically selecting a channel.

According to an answer on superuser.com there is no standards-defined behaviour for automatic channel selection, and some vendors will switch channels during operation. I have not been able to determine if that is what happens here, but I suspect the router does “channel hopping” since the problem sems to have disappeared after I changed the setting to use a fixed channel again. My router is a Telsey CPL4.

I still think this is a bug, but it may have been there right from the start. If the channel is changed while I am connected I can accept that the connection is lost and must be re-established, but I should not have to re-type a password which has previously been stored for the WLAN.
