Disconnection en masse

Having read both good and bad reviews on Amazon in detail, I had decided for this router. However, I have no pleasure in him. He first ran for three days without any problems, then he started the WLAN connection about interrupting every five minutes ... on the advice of some Internet forums, I then made him a reset and downloaded the update for the router. Was then overjoyed that the reviews on this page are the router still righteous because he was going well. No interruptions, excellent wireless range and even though we were with four devices on the network. But after about 5 days, he began again to spin. Since then you have to turn off about every two minutes, and then re-enable the WLAN to get him up and running. The TP-Link support is no help, because he unfortunately ignored requests completely (at least for now). If anyone knows a workaround for the problem, he can sign up like. Perhaps I think then the rather bad review of this router, which gives me nothing but trouble.
