Ok Kool does it matter where I paste it ?
No, the first line should be the one called:
config queue 'eth1' and all the other ones should be indented, so please move the top 5 lines to the bottom, and indent theoption linklayer_advanced '1'`
like the others.
These changes should put the linklayer and per-packet-overhead adjustment on solid footing.
That's hardcore doing it on a mobile.
Move to the top and hit ctrl-K five times, that will remove 5 lines and store them. Then move to the bottom and hit ctrl-U to paste the lines back.
When done hit ctrl-X, verify you want to save with 'y', verify file name by hitting return, and nano will save the file and close out.

Ok boys I think I did it should I reset the router? I'm guessing yeah?
And @moeller0 as for this R7800 SQM settings keep causing bufferbloat 2 u sent me how do I implement those? Do I need too? I'm not sure what u wanted me to do here
I copy and paste the 2 echo hynman provide and hit enter that was it?
You should read the relevant posts in this thread, as I said, I do not have access to an r7800 so will not be able to give detailed instructions.
I did everything that was given to me my performance got worst than before except my upload my upload is the one thing that's consistent everything else is just bad any alternatives or fix?
Well, this is a process and we are not close to finishing it yet.
Could you please post again the output from your current configuration:
cat /etc/config/sqmtc -s qdisc- the result of a dslreports Speedtest
The goal here is to make your observation that things got worse easier to analyse.

Ohhhhhhh lol got you I will post tomorrow morning. Omg thanks for the amount of help
Uhm... Looking at your results in the first post you're within a reasonable difference 15-27 vs 14-30ms which are good results in general. I doubt you're going to see much of difference but we'll see...
Edit: Ahh, i missed that the images you've posted can also be opened as links not just as images.

1st dsl test:
2nd:
3rd:
4th
So the upload seems reasonably well controlled, albeit a bit low:
(22.53+21.63+22.76+21.82)/4 = 22.185 Mbps
out of
29.750 * ((1500-20-20)/(1522)) = 28.538 Mbps
theoretically possible, could be an interaction with the docsis request/grant cycle, but bufferbloat seems well controlled. You could try to set the upload limit a bit higher, judging from the NoSQM test in the first post where you saw 34.9 Mbps (with still not terrible but spiky bufferbloat) I would thing that you might be able to go as high as 35000 for the upload shaper rate, but please test this 
Without a download cake instance download rates seem better, if variable:
(197.7+211.3+210.5+209.5)/4 = 207.25 Mbps
The bufferbloat however especially the spikiness seems less than ideal for gaming.
I believe the next step (after trying to increase the upload/egress shaper) should be to optimize the r7800 specific issues, but for that I can not really help you much, so you would need to follow the advice and instructions in the r7800 threads. After that is improved we can go back and try to see whether we can improve the download bufferbloat without having to trade in half of your bandwidth to do so.
Good luck.
I really do need help with the download... Like severely idk how to fix this.... Idk who I could ask or what type of post I need to put can u help me with that please
When I tried to set a limit on download my speed test just crashes
Interesting, what limit did you set and what was the result of the speedtest, any specific error message?
Wait, back up. Your ping in both cases is between 15-30ms -- that's ideal for gaming. Your other stats (bandwidth) in both cases again are way overkill for gaming. I game at 20-30ms ping, and my maximum up and down speeds are 5.6 megs and 600k on my end-of-the-line country DSL connection. Now uploading to YouTube and downloading patches is painful, but that's a different story.
Now, if your games feature streaming video that's essential for mission success, then that's a different story - even then you have a more than adequate connection.
So either I'm missing something in your original post, or you're having trouble in a specific game or something which you forgot to mention. shrug
Well, that is the unloded "ping" with an idle network, if you clock on the images you get to the dslreports detailed results page with more in-depth bufferbloat plots (click on the labels/links "Idle", "Downloading" and "Uploading" for the results from all probes, especially look at up- and downloading, the results are a far cry away from 15-30ms).
