Frequently Dropping Internet on Ethernet and Wi-Fi

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 copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.

OK so the upstream power is too high and it may be intermittently fluctuating even higher out of spec. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.

In an effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1000 MHz, bi-directional, and no gold colored garbage from Radio Shack, Home Depot, Target, etc. Splitters should be swapped with known to be good / new ones to test.

Also check the coax cable for any damage such as cuts, nicks, abrasions, kinks, sharp bends, etc.

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two-way splitter connected directly off of the drop from the street / pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.

Good luck with it !

Please post back here with how you make out.

Please do. It's still on the high side. 40 to 45 dB is the desired range. There's not much wiggle room, but it may be OK as long as it remains to be rock-stable.

So far it has been much better. Only 1 drop vs the 5+ a day I was having.

The downstream power went up a bit to between 5-8.5.

Upstream has still been around 46-49.

I don't have any splitters in the line at all now but the cable looks pretty old. Swapping it out to a newer cable this weekend in hopes that will get the upstream down a bit more.

Thanks a million for all your help @EG ! I learned a lot just from your responses.

You are quite welcome ! 49 dB is worrisome. Post back here with how it goes.

Quick update on this.

Replaced the coax inside my house to a single new cable from outside straight to modem. Still had issues after this and upstream numbers were unchanged. 

Tech came out yesterday (who was amazing and super helpful!) and found an issue with the underground cable. 

They ran a temp cable and scheduled a new line bury. Temp cable has been perfect so far and upstream power is stirring around 40-42. 

Thanks for circling back here with that update ! Hope things hold up for you now ! Best of luck !
