Hi guys. I have a TP Link WR740N router. I'm trying to share files between the computers that are connected to this router. Both my PC and my laptop are connected to LAN ports by cable but the network only works when I unplug the Internet cable from my laptop and it connects through Wifi. Then I can see both computers on my Network but still have problems creating Homegroup (when I try to create it on my Laptop, it says that I can only create it on Home Network even though it says it IS Home Network in Sharing Center.) Also I have a satellite set up box connected through cable to my router and I can only access it through FileZilla from my laptop when the laptop is connected through Wifi (I can't access it neither from my plugged PC nor plugged laptop). I tried troubleshooting for Homegroup problems but it said that some network issue is present although the Troubleshooter coudn't identify it. I think this happened to me even before I flashed my router to DD WRT v24-sp2 (03/19/12) std, but I don't quite remember. Any help?
