What do the modem's signal stats look like ? Try getting them here http://192.168.100.1 or here http://10.0.0.1
Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
What is the exact make and model number of the modem ?
Is this a WiFi connection ?

I made a post ealier requesting a tech visit due to my internet dropping about every hour. You asked me to post downstream and upstream statistics. Below is what I ran. I am connects wirelessly thorugh a router. My router is an TP Link AC1750 - Archer A7, my modem is Arris SB6141.
Are there any error log entries being shown ? If so, please post them as well.
Can't see your pics. Since you are a new poster, they need to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting them at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to them here.
The SNR is too low / out of spec on channels 10 and 15. Try power-cycling the modem to see if it will lock on to a different set of (perhaps cleaner) downstream channels.
