An alternative solution if you have root permissions - You can check and change the GCM heartbeat times manually. The default is 900000 (15 minutes). I set to 240000 (4 minutes) to be safe and avoid 5 minute router timeouts.

Check heartbeat time (shell)

adb shell
su
sqlite3 /data/data/com.google.android.gsf/databases/gservices.db "SELECT * FROM main WHERE name ='gtalk_max_server_heartbeat_time';"
sqlite3 /data/data/com.google.android.gsf/databases/gservices.db "SELECT * FROM main WHERE name LIKE 'gtalk_%heartbeat_ping_interval_ms';"

Change heartbeat time (shell)

sqlite3 /data/data/com.google.android.gsf/databases/gservices.db "UPDATE main SET value = '240000' WHERE name = 'gtalk_max_server_heartbeat_time'
sqlite3 /data/data/com.google.android.gsf/databases/gservices.db "UPDATE main SET value = '240000' WHERE name LIKE 'gtalk_%heartbeat_ping_interval_ms'

Change heartbeat time (Android)

Process proc = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(proc.getOutputStream());
os.writeBytes("sqlite3 /data/data/com.google.android.gsf/databases/gservices.db \"UPDATE main SET value = '240000' WHERE name = 'gtalk_max_server_heartbeat_time'\"\n");
os.writeBytes("sqlite3 /data/data/com.google.android.gsf/databases/gservices.db \"UPDATE main SET value = '240000' WHERE name LIKE 'gtalk_%heartbeat_ping_interval_ms'\"\n");
os.writeBytes("exit\n");
os.writeBytes("exit\n");
os.flush();
os.close();
proc.waitFor();
