I could set up the SPA 3102 in bridged mode behind my ZyXEL P660HW-61 router. The Linksys adapter works correct, except that there seems to exist a certain communication problem between the two. From time to time (somewhere between about 5 to 20 seconds) the connection is interrupted for about a second. At this occasion the corresponding control lights on the adaptor and the router turn off. In some of these cases the telephone connection may also break. What may be related to the same issue is the following behaviour: From time to time it becomes very difficult for the browser to completely load the configuration-menue. Router: LAN with Static IP and port forwarding SPA3102: bridge mode Does anyone here have an idea of a possible reason and a way to correct this? Thanks for your help.
