Power cycling cable modem & router got me 20% more speed

[Pgoodwin1]

I noticed about a month ago that my speeds via Ethernet to TIme Warner Cable had dropped. I power cycled the cable modem and my router today and got my speeds back to where they were. The trend plot was very helpful CA3LE.

I guess every once in a while you need to clear their brains out.

Not sure if the Cable Modem or the Router did the trick but I'm guessing the modem.

I was just about ready to call Time Warner on the lower speeds, but today I was by myself here and nobody using the equipment except me, so I power cycled everything.

Some DSL routers I've used in the past did something similar where it seems to be related to how they deal with and recover from noise on the line.

 

For example, on Smart Telecom's (former ISP here) earlier DSL router model, if there was excess noise on the line such as the DSL line passing someone's home who operates welders, power tools, etc., it would resync the connection to achieve a 15dB signal-to-noise ratio.  However, when the interference went away, the DSL router remained synced at that lower speed until it was rebooted.  My brother had this issue and had to keep cycling the power each morning to get the speed back to normal.

 

Most of the newer DSL routers seem to periodically resync to adapt to line conditions.  The main problem I've had with this is the Internet connection being interrupted during each resync with long cable runs, so I'm using one that seems to stick whatever it synced at until the next reboot. One of my past ISPs use to trigger a resync around 12:30am each day. 

 

If this happens again, one idea would be to use a plug-in timer that cycles the power every night at 3am.

I power cycled the D-Link router without saving the event log, so I don't have anything to look at from a month ago. The cable modem status event log didn't erase itself and showed a couple of "Lost MDD Timeout" events and a "No Ranging Response Received" events about a month ago, but I have no idea what those mean.

How exactly do you power cycle the modem and router? Just turn it off or hitting the reset?

Unplug it for 10 seconds and plug it back it.  Do the same with your router if you have one.

CA3LE have you ever used the windows "Power Shell" to tweak your speeds. I just started playing around with it. I used it to increase the speed on my network adapter . This is what I set mine at. I only Have a 105mb connection download and a 5mb upload.But I hacked around in windows Power shell and set my network card toWindows 10 Education (64-bit) Build:10240 6.3 04.08.2015 00:22:18
