Gigabit Internet is intermittent and very slow at night 10~30Mbps but works fine during the day!
Since 10/28/2020 my internet has been intermittent and extremely slow at night. This issue starts between 8PM and 9PM CST every day! The speeds begin to decrease between 8-9PM to 100 -200mbps then continue to drop as the night goes on. Around 12-1AM the speed is at 10-30Mbps. The upload speed is largely unaffected and stays between 30-40mbps. The internet "magically" returns to full speed between 8-9AM. Also, TV and Alarm is essentially unaffected. I have had 4 techs out all who say everything is fine. (They come during the day when the internet works fine, and I get 940Mbps down.) The techs replaced all my connectors to "continuity connectors" and have checked every line for noise + voltage inside and outside my home. My 1 to 3 splitter and filter were also replaced. All of that was done in hopes that it was an undetectable issue at the premise. It was not.
I have tried every trouble shooting technique I can think of to run as a consumer. Reboot gateway, Replace Gateway, check physical connections, disconnect everything from network except 1 wired PC to run tests.
Currently I am waiting for the area supervisor to acquire a "wide open modem" on Wednesday 11/11/2020 to come and split my outside line to catch the issue when it happens. Upload speeds stays consistent even at night. Only the download speed is affected.
I have a done over 400 speed tests at various hours of the day on different servers in different cities and states over the past 12 Days of internet jackery at night. I have also run multiple traceroutes to comcast from a wired PC and directly on the GUI of the XB6 gateway. High pings, packet loss and timeouts occur randomly at " ae-151-1203-rur01.almeda.tx.houston.comcast.net [18.104.22.168] " and " ae-12-ar01.bearcreek.tx.houston.comcast.net [22.214.171.124] " It seems the repair teams don't want to look at the plant or IPX as a potential issue even though it potentially is.
My internet is unusable for about 12 hours a day. My smart home, devices and routines are severely messed up without internet and I am constantly having to do things manually. I have had to use my cellphone hotspot for internet the past 12 days while I work at night. I have already used 50GB on my hotspot and am quite upset with XFINITY. I asked for a hotspot from XFINITY mobile to use until this issue is resolved and was told it is not possible. --- really NOT a happy XFINITY customer since 2015.....
Does anyone here have any suggestions, or the ability to escalate this issue higher up?
