I have my computer plugged directly into the router. For the past few days I've been getting 18 MB/s download speed when I usually get about 3 MB/s. While on my laptop in the living room (the laptop is connected to the wifi) it was only getting 30 KB/s our internet speed on the router is actually at 18 MB/s download and around that with upload speed too. I do not know what to do. We have Time Warner for our internet
