Hi all, I've been having a few annoying problems with my network. My network has: wired: mac mini, printer, small server wifi: macbook pro, airport express, iphones I retired my old Netgear DG834Gv2 in favour of a new Billion 7300n based on it having good reviews. I often rely on being able to access my local server by, for example, using Code: ssh servername.local I also use my airport express constantly to stream music. --- Now, having upgraded both OSX (to Lion) and my router (to 7300n) I am having the following problems: On freshly connecting to the network, my macbook pro uses airport express/server perfectly. After a while (I don't know how long exactly, maybe an hour) iTunes pauses and won't play because it says it cannot find the airport express. Airport utility can see the APE but cannot connect to it. I can no longer access my server using it's hostname, but only its IP address. NB: My iPhone can always access the APE (but this could be because it regularly disconnects and reconnects to a network (ie if it is idle, it disconnects). As far as I can tell, the wired Mac Mini doesn't have this problem, but I will test more thoroughly and update. All devices on the network are assigned fixed IPs by the router, the attached screenshot shows my wifi settings.
