Linksys Wireless Router :: E1200 Always Disconnects Every Time At 1 Am Or Something

i recently bought an E1200 to replace my old Linksys router that died. I set it up smoothly and i can connect any device to it easily. But i have one major problem with it, it always disconnects every time at 1am or something. I usually leave my PC to sleep mode  and when i wake up i just take it off sleep mode, now i had this router for about 4 days and every morning when i turn the PC on the internet connection is gone/disconneted. I cant repair it from the Network Sharing Center, i need to restart it THEN repair it and it always says that the Local Area Connection is disabled even though i didnt even touch any of it. I tried putting it in sleep mode in the morning and then turning it on again but the internet is still connected, it just happens when i go to sleep at night, really weird.
