Hello! I am young IT expert, so i take care about home network. I have a problem that internet connection freezes and hangs. We have modern, brand new cables and devices...our ISP has brought internet to us by optic wire. Then optic is converted to LAN cable, and it goes directly to our first wireless router. (ASUS RT-N14U) which is aprox half year in use. Next to this router is notebook which is connected by wired cable. From there there is 15 metres cable to another switch, which connects next mini router (TP-LINK TL-WR702N), SMART TV and next notebook by LAN cable to the INTERNET. So the problem is that sometimes internet freezes for 30 seconds on all devices (android smartphones, wired or wireless conected notebook). I tried everthing. Restarting router. Bought new devices, changed cables to brand new and replaced all possible wifi conection by wired connection and chose also LAN cables CAT6. Wifi chanels optimized, no possible disturbance. Our actual internet speed is 10Mbit download and 1Mbit upload. I also plan to change ISP, to the new, faster (300Mbit download and 30Mbit upload). But i still think that problem is in our home network. All values in routers are set to default. I haven´t changed anythink, can someone advice me something what to do? THANKS IN ADVANCE EVERYONE
