internet lag after switching to new plan

Thanks but I switched my modem to the Netgear CAX80 which was is a recommended modem listed at mydeviceinfo.xfinity.com for 1000 mbps plans.  Pretty sure that means its compatible.  

After chatting with tech support we're under partial conclusion something in-line outside of my house is not capable of gigabit speed.  Quadruple checked the boot file and provision to my modem as 1 gb is correct and that my Netgear CAX80 is compatible.  I have a technician scheduled for Monday 10/5 to figure out if they can actually offer 1 gb speed to my location.

Still have my technician appointment tomorrow but wanted to post another pic. 

Recap from yesterday, speedtest directly from my modem is around 450 mbps (speedtest.net built into modem, not my computer connected to it), my plan incorrectly still lists 70 mbps, the boot file/provision being sent to my modem is correct 1000 mpbs. 

So I moved my computer today to direct connect to the modem and speedtest through xfinity and I'm getting the 1000 mbps, BUT it says I'm "getting all of my 70 mpbs and then some".  This proves the line outside and through my house is capatible with 1000 mbps.  I'll see what the tech has to say tomorrow but in my opinion it still appears they are somehow mixing up two different boot files.   Or they have the provisions mixed up.   

The issue is with wired and wireless because the service isn't working correctly.  I normally have my computer connected to a 100 mbps port, but even when I direct connect to the modem to get the 1000 mbps, the system still lags.  Here are current my signal levels (snapshot of them) and event log (log was cleared a few hours ago to see what happens).  Also check out this thread 

The tech visit at my house today went well, nice guy.  Unfortunately it didn't fix the internet lag though, so I'm not sure what to do.  As far as the technician side of it goes there's really nothing more he could do.

He removed the amplifier which wasn't needed anymore, replaced my old splitter going into my modem and dvr, and also replaced the old MoCA adapter.  I was hoping the issue would be the splitter and/or MoCA because I forgot about those.  His system showed everything working perfectly, all signal levels checked out and speed levels accurate with my modem, but basically were the same signals as what I posted above prior to those changes.  I have 0 uncorrectables now though so I don't think the issue has anything to do with signals.  I just cleared the event log again to see what might show up later.

I didn't get a chance to test really out the internet issue while he was here because he also swapped out my dvr for a newer one (still x1) and we were messing around with that.  My bad there, I should've been testing the internet to show him the problem after the changes but I don't think there's anything else he could've done. 

I showed him the 70 mbps thing on my account and the xfinity speedtest 70 mpbs thing above.  He said the myaccount stuff is having issues and doesn't know what's going on.  Could my lag issue have something to do with that?  What should my next steps be?

I didn't have this internet lag prior to switching to this new faster internet plan last Thursday.  There are absolutely no issues with the x1 system, only internet.  Here are some examples:

• If I open a multiplayer game the game will freeze and reload the session almost every minute.  Other players in the game claim to be unaffected by it.  So I'm not slowing them down.  That makes it seem like a signal issue but the signals in my modem look fine.
• Another example, opening web pages.  To open this particular post took three attempts.  The first attempt after 20 seconds said the page was unavailable, after clicking refresh the page loaded instantly, then when I clicked on the reply button it took about a minute to load this entry form.  Same thing happens on other webpages, sometimes load instantly other times hang.
• Example of streaming video via internet, Netflix doesn't have much problem.  Only issue there is allowing it to autoplay into the next video cometimes cuts the sound until its paused and unpaused.  Hulu via app is almost unwatchable, its like the video game lag.  I haven't tried Amazon Prime or Disney+ yet but I'm guessing those will be the same since loading webpages have issues.  

Curious, does the starting frequency matter?  Its starting at 513000000 Hz

Another t3 timeout last night.  Starting to look like a signal issue.  I forgot to post below but downstream was at -9dBmV earlier and is currently -7.9dBmV.  Any chance someone can escalate this to an engineer to see if an amplifier in my area is having issues?

No new event log entries today, i.e no t3 timeouts or tlv11 unrecognized oid.  Been surfing the web for about 10 mins now and no issues.  Also notice the myAccount stuff is correctly displaying my plan now.  I won't mark this as resolved yet but I'm hopeful!  Maybe it was just something that hadn't adjusted to my  new plan yet or maybe they just happened to fix a line or an amplifier in the area without my involvement.  I didn't get a chance to chat with my neighbors this past week to see if anyone else had any issues. 

At this point I think I'm good to go.  I'm not sure what changed, syncronization issues and/or fixes somewhere outside I'm not aware of.  Nobody told me anything.  Wish I could say what fixed the problem.  All I know is for 3 hours now everything internet related is working great, no event log issues etc.  I did notice my downstream OFDM channel power lowered a bit to a better spec.  Makes me think Xfinity fixed something somewhere outside.  

I guess mark this post as closed if you deem my info worthy of 'best answer'.  If the issue happens again I'll make a new post.
