Very slow internet connection

My internet has been extremely slow. I went through the malware section and confirmed there is no malware. I am wired to the internet and checked my connection speed, 3.54 download, 4.24 upload. I should be around the 30mbps range. I checked another computer on the same network (wireless) with a speed of 24.39 download. I have used JRT to clean junk, it produced a log and then i followed the rest of the clean up form the malware section and it deleted the log.

Please help

Thank you
