What i do for the pi is set a static IP address. This way, i can route in at the same ip all the time and it will never change!
I noticed my end that runeaudio.local or
http://runeaudio etc doesnt work ALL the time for me. So i had to resort to a static IP. <-- At least i can now connected 100% of the time.. Only thing is, at first you need to keep looking for the ip you set it too but now it comes natural to me.. Try keep the ending IP digit simple? EG: 192.168.0.100 the 100 is what i mean by simple

.
Hope this helps!!

Will.
