Got mine up and running last evening. Works like a charm.
Mid-20s are common.
A security suggestion for those not used to setting up home networks. Once connected to the Mobley:
1. Log into the administrator app
http://192.168.1.1 using the default id "attadmin"
2. Go to "Settings" --> "Main Wi-Fi Network" and change the network ssid and password to something not meaningful or personally identifiable. This will cause the Mobley to reset and come up with the new ssid and will require the new password, which will kick you off, so be sure you've written down your new ssid and password so you can log in again.
3. Log into the administrator app again using the default id "attadmin" then go to "Settings" --> "Advanved" --> "Administrator" and change the admin password to something other than "attadmin", preferably something not meaningful or personally identifiable, and again be sure you've written the new admin password down first.
This will provide decent, minimal security against unwanted users logging into your network.
To prevent a network dropout every 30 minutes, Log into the administrator app again (using your new admin password), go to "Settings" --> Advanced" --> "Power Save" and change the drop-down selection to "No Time Out".
