@Sevi @Carl Just wanted to let anyone experiencing a similar issue what my findings were. I was having similar issues of having my download and upload speeds capped at around 280mbps even though I pay for fiber 1gbps. I swapped out my AX50 for the ISPs router and my speeds went up magically to the 900's down and 350's+ up. At this point I got real curious as to why this may be happening because I truly do enjoy using the TP-link user interface (well, enjoy it much more than then one from my IP at least). 

 

After stumbling on this forum, I took the advice of many before me and reset the router, but just the router using my tether app (I didn't do a full factory, just the option that let me wipe the settings without wiping the TPlink credentials. 

 

This seems to have fixed my speed issues, at least for now. I am regularly getting speeds in the 900's now for down and 350s for up. I will continue to monitor and see if this works out ok without having to change anything else or deleting the tether app. Just wanted to let you all know that the issue seems to be around the QOS part. Once I reset everything and didn't mess with those settings, I seem to be back up to where I'm supposed to be at.

 

If anything changes, I will let you all know.

 

Hopefully this QOS issue can get resolved because I simply don't have the money to go and purchase another router right now. It is somewhat upsetting that many other people seem to have been reporting the same issue but a whole year later we don't have a solution from TP-link.

@Sevi 

Hello, I just bought the router and have exactly the same issue, i cannot perform above 50/60 Mbps both wireless and cable, the old router goes fine to 250, the connection is up to 1GB which is the reason I bought this one.

 

I do not have the app installed, I use the web browser to install and configure, adding nothing else than provider connection parameters. 

 

I read that i should remove the ax but i cannot find any way to do that.

 

Very disappointed that such pervasive issue is not solve, there is no point in paying more for getting a fraction of what i get with a 12 years old router.

 

Pls how can i solve this?

@Carl 

 

pls can you help how to deactivate the ax? the speed is dramatically lower than my 12 years old router.... terribly slow both wireless and cable...

Thank you Carl, in the QoS tab i only find the option to set priorities, not to deactivate it, any other place where to make it deactivated? Thank you!!

@antnas 

 

Hey there, if you're having issues with the QoS, it might be best to return your router to factory defaults and make sure to not turn on that service at all. That seems to be the common theme/solution on this thread that has fixed the issues for most people, myself included. 

@HisMessengerDAB 

I do not find the option to deactivate it, it's only a priority setup, not on/off...

 

 

@Carl 

done but zero improvement, and QoS there is no way to set ON/OFF, see the screenshot, what else i can do? this is really inconvenient, to stay polite....

@Carl 

firmware is updated to the last, i did several factory reset as well, provider is Reutov.ru (Moscow, Russia). If i use the old router i get 200+ with no issues, both cable and wireless, its limit is 300Mbps, while the connection is 1Gb ( that's why i want to replace the router with the Archer).

 

what else i can do? Thanks!
