Hi ... internet, wifi etc are all working fine. Connecting to the router displays the home summary page ok, but selecting any of basic, advanced or help tabs just hangs. The router is still operating ok as can access web pages, wifi. If I then click refresh, router shows line disconnected (it isn't) and reconnecting again shows the home summary page ok. Strange thing is this was working fine a while back and no config changes were made at that time. Power on/off hasn't helped. Any ideas?
