[Q] How to connect my GT-I9300 to my router when SSID is off?

Well due to a suspicion of someone in my area trying to get into my network I disabled the SSID.
Since then my GT-I9300 stopped seeing it, says it's out of range. My router is TP-Link TL-WR1043ND

Any way I can fix that? I have stock rom with root.
