download and run inSSIDer
on a wireless capable device such as a laptop. let the program look up wireless networks within reach of you (move around your property where you want connectivity so the scanner can pick up all network).... note which channel number each uses. then set your SH to use a channel number that isn't
in use. the channel numbers range from 1-13.
don't leave the SHs wireless channel as auto.
to access the settings on the SH put the following address into your web browser bar...
login (default: username: admin - password: changeme)
advanced settings below the 3 red boxes
to your left wireless settings
set channel to whatever channel that isn't in use
the above could possibly fix the issue but..
also note the SH isn't the best for wireless so depending on your property, the signal may not be strong where its disconnecting which could then mean you investing in a wireless router
