Hi my modem seems to be stuck in some sort of loop and well im wondeirng if anyone knows wtf is going on, the guys at support surely don't and they will send a technician in three days at the earliest. And he would arrive "between 8 am and 4 pm" ..... In other words an entire day of university/work wasted sitting around waiting for the technician, so if anyone has any clue of what this might be that i could tell my isp support or try myself i would be extremelly gratefull.
The problem: My modem has a bunch of lights as any, they are from memory(at uni): DSN, US-something, Online, Link.
When you restart the modem it boots everything up in order, one light goes on then the next per the normal. The thing is however once it has gotten all lights to a stable position, the last one - link, starts blinking a bit randomly and then it starts the whole process of going through the "checklist" of lights again. In other words we have internet for about 20 seconds every 3minutes. For these 20 seconds the connection functions as normal, no slow loading or anything - ping is also fine.
Our router recieves an IP from the modem at all times during this.
From 6 PM to about 1 AM we had it online for like 20 seconds. Around 2 AM i was able to stay on for 20 - 30 min at a time. This morning it was back to 20 seconds again however, maybe even less.
Backstory: For a few days we've had some lagspikes, i was however studying so i didnt really care but i restarted the modem once or twice and it seemed to fix it for my girlfriend playing TF2. However last night i was playing D3 and it started spiking again. So i do per the normal when anything like this happens - i restart the modem. When it comes back on, the connection or modem is stuck in this loop of "restarting" itself(power never goes off however) with the checklist.
Any help would be greatly appreciated

This sounds like an interesting problem indeed.
To clarify: you have your devices directly connected to the modem without any interference from a router? Are they hardlined or is Wi-Fi built into the modem?
It sounds like it could be an issue with the power going to the modem, possibly causing it to reboot periodically. Check to make sure that the outlet/power strip that your modem is plugged into is in good working order and the connections aren't loose.
What is the make/model of the modem? What is your ISP?

im a cable technician that goes to houses all day for the same problem. the steps for the modem are first, its going to look for its downstream carrier. lock into that frequency and then look for the upstream carrier. once locked onto it then you should have the link/ready light, it will flash a bit then remain solid, (depending on the modem). at the point it is sync'd. you can run what we call an "EQA" this test will check your downstream and upstream levels. as well as downstream and upstream noise ratios. your cable tech that comes out will have a meter he can test this without the modem. the problem could be a few things. weak downstream or upstream signal (this is doubtful because if it passes those steps during the sync then its usually decent enough not to drop offline right after. but if those signals are borderline. simply adding 3.5db would give you a lot better connection. but since it syncs the and ready light you might have snr problems (signal to noise) for either downstream or upstream (upstream = transmit level of the modem to get the signal out the house) The modem could also be bad. what u need to do is if you have Charter cable to PM me because i can get balls rollin. other than that call your ISP and get someone on the phone that can run an EQA (a simple test to check your downstream and upstream levels, along with noise ratios) and as soon as your modem comes online they need to test it. if the modem is offline or not sync'd up they cannot test it. it will show a dead modem because its not communicating yet) to fix the problem yourself. you can find reduce the splits in the cable before it gets to your mode. if the cable splits in the room with the modem and feeds a TV or telephone modem (assuming you might have cable phone and its working ok?) important question becuase its a modem too and if it works then the internet should work, on its line of course) a 2-way splitter looses 3.5 db, also make sure ur coaxle connections are tight, not too tight, just finger tight. if thers not a splitter in the room, go outside where the power meter is and u will see your cable line coming in, it prolly splits there or under the house/in the attack and feeds a bunch of rooms. every split weekins it so if u can put the cable modem line on the first splitter that would be good. also if u have a 3-way splitter, 1 port will lose 3.5db while the other 2 will lose 7db. make sure the internet is on the -3.5db port, it should say on it. any questions ask away!
