Hello. I have a problem with my modem, when I connect directly to it, you start seeing multiple failures such as loss of donwload and upload, random connection and disconnection of network cable, etc. But when I connect the modem to my router Tp link model: TL-740N and from there to my computer by Ethernet cable, the internet works well. Well, I want to connect my pc directly to the modem to get better performance in games and I can not. Someone help me pls? . Before I had windows 8 format and return to windows 7 and I still have the same error. I have installed the latest driver for my network card and when I do the test with the Internet through the router everything is fine. But when I do the modem everything is a mess. Thank you! Sorry for my grammar
