So I recently moved my service to a new address. While the internet has been great for the most part, there's been a persistent problem. Around 10pm at night, roughly every night, the upload speed for my connection falls off a cliff. I ran a few speedtests and found that my downstream is still rocking at 57mb downstream each time, but I ran one at 10:30 (0.00mb upstream - didn't complete) 11:00 (0.40mb complete) and just now (0.84 complete) for the upstream. Needless to say, I think this falls well outside of acceptable range for an upload. I've checked with my roommates and they've notified me this has been a problem since before I moved in- they have your residential service and it happens to them too. I need to get this rectified soon, please let me knwo what can be done.
Hello SFJonasTRK and welcome,
You need to login to your Comcast Gateway using 10.1.10.1, cusadmin/highspeed and check out the upstream power levels to be within >42 db spec. If they are not then call 8003913000, use technical and have technical agent look into your modem to confirm then have him send a techician out to handle these signaling issues.
Hope this helps you out.
All my upload power settings are at 49-50 db. So that's not the issue - if it were, it would never be at proper upload speed. Again, this is happening for anybody who's on the coax in my apartment, including my roommates. It's not the Gateway.
So to bump this, since it's STILL not resolved: We had a tech come out and do a check on all of our equipment, and told us that everything in our apartment is set up exactly as it's supposed to be and the wiring, equipment et al is in good shape. He also fixed something on one of the taps in our apartment building's electrical closet. We seemed to have less upload drop for the first few days, and then...right back to where we started. Last night especially, we had our upload stuck at .38. I called Comcast business again and the only thing they said they can do is send out another tech. I don't know what this is supposed to accomplish, other than now having two people say "Yeah, your equipment is fine...not sure what's happening". I'm also upset that I've explicitly told everybody involved when this is happening for proper troubleshooting and there seems to be no impetus on Comcast's side to do anything other than have me repeat the same steps over and over again. I don't want to lose another 2-4 hours of my weekend to wait for a tech that's not going to do anything the other tech's haven't done, nor do I like paying this much for internet access that gets crippled reliably EVERY NIGHT. This needs to be fixed or I need to be properly compensated for being unable to use my internet on my schedule. This is ridiculous.
How long after 10pm does it fall off a cliff?
Are you running the Comcast router or your own router? That is, what is the IP address of your PC, is it a private or public address?
