How do I fix my slow Comcast Internet speed?
A2A. Without knowing more details, I can only speculate and guess. It could be many things.Gather facts. What are your exact speeds? What is your subscription package? Do you have also packet loss problems? (Is packet loss the cause of your speed issues, or no.)Rule out equipment... plug a known good computer into the modem directly... remove extra routers, switches, definitely Wifi for this test, etc. Test a single device to establish a baseline. Do you have multiple devices/computers? Do they all have the same issue? Try different devices, if you can. Run "SpeedTest" applications on mobile devices, laptops, PC/desktops, etc. Ideally start with only wired devices; Wifi is a common problem ... make sure the problems exist aside from Wifi. Meaning, you may be having network/Internet issues, but the issue is not necessarily Comcast's fault or within their ability to resolve.Back to gathering facts... record data. Are the speed issues related to time of day? Intermittent or consistent? Record your speed test data. Do ping tests, record the results. Provide all of this hard data to Comcast, as applicable/needed.Call Comcast. Ask them about your signal level, your modem performance (SNR, signal to noise ratio, Rx and Tx signal levels, uptime/stability, DOCSIS timeouts).Good luck.Have your problems always existed (with your current installation/configuration)? Or just started?When speaking with anyone... be as polite and factual (rational) as you can. Emotions do not help resolve technical problems.
