Connection Dropping

Is this with a WiFi connection ? If so, as a test, does a computer / device that is hardwired directly to the router / gateway device with an ethernet cable have the same problem ?

With this test, we are trying to isolate this down to being either a WiFi-only problem or a problem with the general connection to the Comcast system which would of course affect both. It's a good first step in troubleshooting before proceeding any further. 

OK. 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.

If it helps I've noticed that downloads are very inconsistent. It'll be fast, then slow then completely stop then work it's way up and down between being really fast to really slow

The signal stats were o/k at that snapshot in time. Are there any modem RF error log entries being shown ? If so, please post them as well in their entirety (copy and paste them, don't post a screenshot) but redact the CM MAC and the CMTS MAC addresses for your privacy.

Ran a pingplotter and there is a specific IP that is giving a lot of packet loss and the agent I'm talking to thinks that a tech will be able to fix it at my house when it is clearly a server issue

Still experiencing high packet loss after "network maintenance" was supposed to solve my issue. I had a technician visit scheduled that they canceled so know I have to wait even longer to get it fixed. Also experiencing very inconsistent upload and download despite getting 114% of my data speed

There are server issues but apparently they aren't authorized to put in tickets 

be-32221-cs22.350ecermak.il.ibone.comcast.net shows 80-90% packet loss constantly. I have a new router, internet connection is fine. This is the only server that shows as any real packet loss. Would be nice to have a fully functioning network again

It's actually insane that they have no way to identify server/network issues other than having a tech come out to your house and start from there. Multiple people have been having this issue since the network upgrade. When I've brought up my issues and concerns I get told that a tech will have to put in a ticket when they come out, assuming they don't just automatically cancel the visit because the network appears to work fine on their end

So I'm making a post again in hopes that something will finally be done. I have talked to various people within Xfinity and no one can seem to find what the issue is. According to everyone I've talked to my connection is fine, but I experience high latency and extreme packet loss multiple times a day. The tech that came out said that nothing was wrong with the modem and that all the upstream and downstream power levels were within spec. This is happening on Ethernet and Wireless devices. I don't have time for another tech visit, and if there is nothing wrong at my house, as multiple tests have indicated, then they will come to the same conclusion and nothing will be done still. I get that their SOP is getting a tech out to see what is going on, but seeing how that was pointless the first time I'm not going to waste my time again unless something indicates an issue on my end. They pulled event logs and confirmed that I never lost signal and that everything was ok with their signal. Seeing how a lot of people on this forum are also having this same issue hopefully something is done about it soon. This has been going on since the beginning of April and shows no signs of improvement.

So I just had a tech come out about the issues I've been having, he said that something in the box that connects your house to Xfinity is more than likely the issue. I believe they were some sort of clip that transfers the signal into your house. While it shows Xfinity that you're receiving a "good signal" that doesn't always transfer to your modem correctly. Having them come out and fix it at some point in the future and will come back here if that ends up being the fix
