Modem disconnects from internet every 24-48 hours

@EG​ The first IP timed out and the second asked for a login to the gateway. Where would I find the login information, or is it my Xfinity account login?

@user_ee24f6​ Of course, now that I posted, I can see the SNR in the Downstream values. Hopefully that is what you were asking for earlier.

@XfinitySara​ Unfortunately, no, I have not made any progress. I only understood every third word of what was suggested but I live in an apartment complex so the only thing I'm capable of doing on my own is looking at the outlets I have in my rooms (if I understood that correctly).

Since it sounds like it's the upstream signal and I have no control over it I may be stuck with random disconnects as long as I live here. I've been powering it down each night now and it has so far lasted through the workday. I was really hoping it was the modem.

OK, then please reread my last comment. I think that it's comprehensible..

" then perhaps it's best to book a tech visit to investigate and correct." Good luck !

Oh, no. I'm sorry @user_ee24f6. It can be very hard to understand. Some suggestions were to check your cables connected to the back of the modem and all the way to the wall, and see if you can spot any damage like kinks and bends. If you do, this will tell us those cables need to be changed. If the cables look good, we'll move to another common issue. You can also check the cables and secure and finger tight behind the modem, at the wall, and at all connection points in between (if there are any). These connection points in between could be joined by a coax cable splitter (a little metal type box with one outlet or more that joins another set of cables). These little boxes could be the issue, which is what our Expert @EG mentioned above. You can also Google these to see what they look like. You can then see if it is needed or eliminate it altogether if it is not. The coax splitter takes the internet connect from the modem on one line, and converts the internet signal into two lines where one line can travel to your cable box, so you have an internet connect there. The second line can travel to a computer or other device requiring a cable connection directly into it. We are not sure if you do. This is why we say to remove the splitter, if you do not require another internet connection by cable. I hope this explains it different. If not, please ask me for clarification. This is why we are here.

@XfinityLinda​ Thank you for the explanation, I appreciate it. For whatever reason I was thinking I was being referred to look inside the apartment outlets and external building wires. I'm sure it's just my misunderstanding from the particular mindset I was in at the time. I shouldn't have posted while multitasking for work. I had also lost connection during a meeting, so I was frustrated at the time.

I checked all the cables and reset the connections and everything looks good. The cable was a brand new one that came with the modem and it's in pristine condition, visually. The modem is connected directly to the outlet about a foot away. There isn't a splitter used, so that's not an issue. Everything appears to be good from a setup perspective.

I've been unplugging/re-plugging the modem each night before bed and it hasn't cut out on me between reboots. I know that's not a solution, but it's a band-aid that is working for the time being.

@user_ee24f6 If you are still encountering issues please let us know. As @EG suggested we can definitely get a technician appointment set up for you so you do not need to keep unplugging the modem all the time.
