Windows 7: Wireless connection issue

Wireless connection issue

I'm trying to rack down an issue with my wireless connection. I'm using a new Actiontec C1000A DSL Dual band modem supplied by (Centurylink)Wireless N VDSL2 Modem Router - C1000A for CenturyLink and my internet connection speed shows initially at 144mbps within Windows Network status under (Network and Internet>View Network status and tasks>Connections. After sometime it drops to 1.0-2.0 mbps and will stay there unless I reboot or rest the adapter.

As for adapters I was initially using a Lynksis WMP600N but switched it out with a new D-Link DWA-548. After installing the D-Link I thought I had resolved the issue but nooooooooo the following morning I checked within Windows Network and Internet and it was showing 1.0-2.0 mbps again. I was using the most current drivers offered for both adapters. The system shows an excellent connection between the desktop & my DSL Modem Router when issue shows. I do not have drop off issues at all either. I've tried changing channels as well on each adapter as well as changing setting within the DSL modem.

Hello Udidwht, welcome to the forums, my initial thought would be to contact the ISP and ask them if there are any issues with their equipment.
If they say everything is fine on their end, I would try a flush dns and renew ip using command prompt .

Ok, first option (DNS flush cache) was successful. Second stated, "Could not display the DNS Resolver Cache"
