Slow and spotty internet connection

Everyday I have to restart my modem because my internet is slow and spotty.

This is not something I should have to do. 

For example, I just ran a browser based speed test (my wireless router is 1 foot away from my laptop). These are the results(03:08pm CST):

If I reset the modem the DL speed will restore to 300-400+. 

I am requesting someone take a look at my connection, run some sort of diagnostics. I would then ask that my connection be fixed so that I dont have to reset my modem every day.
