Help with nightly slow downs and disconnects

  • West Columbia, SC, single family house
  • Internet service only
  • SB6141
    • B_KOMODO-1.0.7.0-SCM00-NOSH
      Boot Version: PSPU-Boot(25CLK) 1.0.12.18m3
      Hardware Version: 7.0
      Firmware Build Time: Jul 22 2016 08:13:57
  • Netgear Nighthawk R7000
    • Firmware: V1.0.9.28_10.2.32
  • Purchased speed is 100/10, Spectrum speed test shows 108.9/11.2 during good times, barely 500kpbs during slow downs.
  • Happens both on wired and wireless connections independent of usage (e.g. streaming, browsing, etc.)
  • Only resovled by power cycling the SB6141

This has been happening for about 2 years. We call it the "Prime Time Slowdown". Every evening around 9 PM EDT our internet will slow down to a crawl. A quick reboot of the SB6141 will resolve it until the next day.  I work mostly from home and the service is usually solid during the weekday.  I've even tried to preemptively reboot the modem around 8:30 PM to see if it still slows down; it does. Spectrum reps see nothing wrong with our service.

Re: Help with nightly slow downs and disconnects

You need to find out why your ROUTER'S clock is TWO HOURS ahead of  local time.  What time does your MODEM say it is?  The router and modem clocks should be the same.

Re: Help with nightly slow downs and disconnects

May be time for a new modem... 8 channels may not be enough channels to work with during peak times for your area.

The Netgear CM500 is a pretty decent 16x4 modem that you can find good prices on these days if you are bringing your own modem. Been using one in the Florence market for a while now. We are just over an hour from you via I-20, and we already have at least 24 usable channels here based on the range of frequencies I've seen mine latch since we got bumped up to 100/10 speeds.
