The past couple of days I have had an issue with my upload speed being low. I have ran multiple tests on xfinity speed test and I am usually getting 2-3 mbps upload. I have the blast package and am getting 200-210 download. Earlier today, my upload spiked to 12 and stayed there for 10 minutes and I notice it dropped back down to 3. I spoke with customer service and they did multiple resets and told me everything is fine. I just recently started having this issue and trying to figure out what is causing it. My computer is hardwired. Any help would be appreciated.
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 ?
