Start with the modem's signal stats. Perhaps they already are, or they are close to being out of spec and intermittently they go completely of spec. Try getting them here http://192.168.100.1 or here http://10.0.0.1
Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
Yes. The upstream power is a bit on the high side and *may* be intermittently fluctuating even higher out of spec. That can cause random disconnects and spontaneous re-booting of the modem. In a self troubleshooting 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.
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 !
Alright, I followed your advice and I let a few days pass to see what other problems might show up or how best to optimize my setup. I had one splitter from where it was connected from the electricity pole meets around the power meter of my house. Then I had a cable from there directly to the modem. I still have a router connected to it too. For the most part it has stopped constantly reseting, however I will loose the connection momentarily and get a lag spike randomly. I notice this everytime that I am playing a game and it happens about 15-45 minutes at random. When it does, I look at the modem and router but all the lights seem to indicate that everything is fine. However, all the computers in the house are unable to get an internet connection. Sometimes the issue solves itself after a few seconds, but sometimes it stays like that for several minutes and I have to reset the modem. Last time I reconnected ethernet cable from the router and the modem (unplugged and plugged them gain). This also fixed the problem but I don't know if the modem had righted itself or not in that time. Anyways, should I disconnect the router and just use the modem's wi-fi or is the problem part of something else entirely?
The upstream power is now WORSE / out of spec. This has nothing to do with having a separate / side-car router. I will mention that if are using a separate router with that gateway device, the gateway should be put in to bridge mode. Again, this has nothing to do with your RF signal / connection quality problem from the street. As mentioned before, get a tech visit if you can't get the signals to be any better.
Bear in mind that if the premises facing techs can't find / fix an issue at your home, it is they who are responsible to escalate it to the line / maintenance dept. The problem may indeed lie beyond your premises in the neighborhood infrastructure somewhere.
Alright, I see. Thank you very much for all your help and patience. I appreciate your timely and knowledagble responses. I'll be calling in the tech and see what they can do.
Good luck with it !
