Internet disconnecting multiple times an hour for the past week

Do I need to have the DHCP server enabled on the gateway if I have the IP Passthrough enabled?   

I believe so.  And it doesn't hurt.

DHCP lifetime is not the only thing that can cause a connection to drop.  It is one of them and usually comes up by process of eliminating other potential issues unless someone says "every 10 minutes" and means it. If you have an Ethernet connected PC and no line issues, then it's the best guess. 

If you have Wi-Fi, then it could be a Wi-Fi issue (channel or band changing, or just interference on Wi-Fi frequencies or with neighboring networks).

If you see lights flashing on the Gateway during the outage, that's probably a line issue.

If you and someone on another network experience "disconnections" to the same  server at the same time, then that certainly sounds like something out of the control of you and your ISP. 

@JefferMC Thanks again for the replies.

I should have been clearer with the initial issue; the "every 10 minute" time I gave is completely arbitrary. It's not every 10 minute interval on the dot, it was just an example of the frequency of the disconnections.  

I'm using 2 desktops during most of the day: 1 for work and 1 for personal. My work desktop is using wifi and the personal desktop is using ethernet. They are both losing internet connection at the same exact moments, and the lights are not flickering or changing on the gateway during these moments.

I hope you can understand why it's been so difficult to troubleshoot or isolate this issue.. I'll check with some neighbors to see if they are experiencing any issues.

I'm also in OC area and have this exact same issue, and literally everything said checks out: started about 2 weeks ago, gateway lights don't change at all when the drops happen, both wired and wireless connections affected at the same time, and is very sporadic (ranges from going maybe hours without any drops to having multiple drops within just a single hour (drops last like 15-45 seconds and seems completely random). I was in a Discord call last night with a friend who also lives in OC but has Spectrum. Weirdly enough, when the drops happen, I can still hear him but he can't hear me at all. It's like the internet just goes into a state of limbo for 30 seconds; nothing loads at all, messages don't send, games disconnect, etc. Needless to say, it's getting really annoying. I'm starting a few online classes in a week and am worried that it'll disconnect during an exam or something...

It seems like we all have the exact same problem:

-Orange County, CA Area
-Internet disconnections for 10-20 seconds at a time, happening sporadically and randomly: multiple times per hour or none per hour
-Occurring with devices on both wifi and wired connections
-Gateway lights do not change at all during disconnections

Have these issues always been around for you or did these only begin 2-3 weeks ago?

I am having the same issue.  I live in Orange County, CA and work from home at times.  I had this problem for a few days last month and thought it was an issue with my work VPN which would cut out intermittingly several times per hour. 

My work IT tried trouble shooting and it went a away.  About 12-14 days ago it started happening again.  I re-engaged IT and they have tried many things but no solution.  I tried to call AT&T support but that was not helpful as I could not get past the robot answering/trouble shooting system which told me things were fine and hung up on me (multiple times).  Yes, the internet is fine when it is not cutting out for very short periods of time but it cuts out enough on a now hourly basis to cause serious issues for me trying to do my job (which actually does not even use much data or require a great internet speeds but does need me to have a constant connection to maintain my VPN to the work server). 

I got some help through the "smart home app" only because I was able to chat with someone at 3:00AM.  Any other other time I get a message that they are too busy and to try again (very hard to fix a problem when nobody can help us).  When I did get someone they did some things to optimize my situation but that did not improve things either. 

I checked this chat and see I am not alone.  I have had fairly stable internet with AT&T for a couple of years and other than this issue I have like the service and want to keep it.  This issue does not sound to be due to the AT&T modem (as someone mentioned they got theirs swapped out).  I had my computer hardwired to my laptop.  I have tried unplugging the ethernet cable and connecting via WIFI but same issue. 

I am currently connected via WIFI hotspot on my cellphone and magically no issue.....  Has anyone received a useful solution from AT&T?  Since they won't speak with me on the phone or chat I am going to head over to their store to see how I can get help. 

Thank you all for sharing between what I have read and experienced and now seeing that my cell phone hotspot work without issue I feel confident this is an AT&T issue and not an issue on my end.  I just want a solution with AT&T if possible as I do not want to change service providers.     

Thanks!

i am also facing same problem with my internet, how can i fix it?

@noodle123 Same as heyitsian; noticed it only 2-3 weeks ago. To be honest, it felt like the internet was getting a tad bit better over the weekend. I was able to have 2 night game sessions without any disconnects (Sat/Sun). However last night, I disconnected a few times within that hour, and it feels like it's back to being intermittent for "during the day" internet use as well. I think the accurate way to describe this is that "the internet frequently 'hangs' for 15 sec or more at a time."

I really don't know what to do about this. And after seeing you mention that your friends who have different ISP's were also experiencing similar problems, I feel like switching providers wouldn't even help. I think we've literally had AT&T ever since we first got internet back in the early 2000's, and never had any real issues with it until now.

EDIT: I think the internet has hung up on me about 8 or 9 times in the past hour...

@itchikneesan, I was home and online Saturday morning and I had absolutely 0 disconnections during that time for 3 hours (9am - 12pm). I thought everything was fixed again. I was out on Sunday and Monday so I didn't have a chance to monitor the network. 

Same connections and devices today (8am - 5pm), my net dropped 52 times. This is absolutely unbearable, I can't get any work done due to these distruptions. Anyone else logging their network drops, please let me know if these times match up. 

@noodle123 Holy...that is insane. Can I ask what you're using to log these network logs?

@heyitsian I feel the exact same way. Last night, I couldn't even get past the 2 min mark in the 2 Halo MCC matches I tried playing with a friend. MCC also gives timed, incremental soft bans for quitting and this includes disconnects. So I wasn't even interested in waiting out the timer to get into another match just to disconnect within the first minute, lol.

During that hour (starting 10:40pm) I was in a Discord call with him, I think my network dropped at least 4-5 times. Overall, yesterday felt particularly worse. I'm considering just using my phone's hotspot when I play games or am in calls for the time being because this too frustrating to deal with.
