So my router from CenturyLink died about a week ago. So I got a new router from CenturyLink, and ever since then my internet keeps disconnecting and then reconnecting. I have tried to put an ethernet cable in the back of my computer but my ethernet port doesn't work, so I use a wireless adapter. It is a D-Link DWA-552 Xtreme Desktop Adapter IEEE 802.11g, IEEE802.11n Draft 2.0 32-bit PCI Up to 300Mbps Wireless Data Rates WPA2. I have looked through a lot of forums, and nothing has seemed to help me. My connection is excellent. Speed is 130 mbps.
I would go into the internal settings of the router and switch to a different channel there are a number of channels that you can use and for the most part all routers come preset to the same channel , so changing it may help.
If that doesn't help then you could try doing a reset of the router to factory settings.
You can also try getting another router from Century Link.
