RAX80 - slow speeds

Been in a similar boat since late last year. I was able to get it stable for about two months in the middle, but after a power outage and the router rebooting I'm right back to somewhere between 10 minutes and 24 hours before I drop from 700Mbps throughput to ~5Mbps throughput. It only affects AX chips in my house, of which I have three. They're not all affected at the same time though, and each adapter can be disabled/enabled and function again for a time independent of any impact on the others.

For my part I can't figure out if the issue is the AX200 chip from Intel (the only AX chip I'm aware of still) or the RAX80. My understanding is that adapters based on the AX200 chip do work fine with other AX routers, just not Netgear's. I had hoped turning off/on the QOS would have made a difference, but out of several dozen attempts to fix the issue including the QOS fix, nothing has permanently fixed the issue.

In any case, if anyone does ever see this problem addressed, please update here. And if you're reading this Netgear support staff, please help your management understand that this is not a user issue, and that it is widespread. I've seen this particular issue generate negative reviews for the RAX series, and my guess is more will keep coming in until this is properly addressed.

I have the same WAN speed problem

i get 360 --= >> QOS off  >> goes to 500 mbps, than QOS ON >> goes 940 mbps > 1-2h later >> goes down to 360 MBPS!!! 

IT'S NOT MY MODEM - I get 940 ALL DAY ALL NIGHT -- direclty connecting the modem to the PC

I think netgear knows of this problem, but not many people have 1 gig conneciton, or technical enough to pin point the issue to the router.

I have 4 netgear high end routers which i purchased in 2 years for different locations.

My main house has AX8 or RAX80 - only place with 940 mbps WAN .

WAN side on NETGEAR is problamatic.

netgear FIX this or else you will lose customers and you will have bad rep, as more customer will go on GBPS internet provider.

netgear DO NOT tell me contact your useless Technical support.

I want a solution to this problem, i don't wanna spend another 500$ on a different router

This has been a problem since the beginning of the RAX80.  I bought one initially and had to return it for the same lack of speed issues.  Got another router that works great and is not Netgear. Might want to do the same.  I see that they have now introduced another model that's supposed to be even faster.  Something is worng with this Netgear picture. Get a new canvas.

Dustin_V  What do i need to do to get my router fixed replaced or refunded? 

Thank you,

Forget about being fixed - I think they would have found one by now.  Replace?  You really want to replace this with another RAX considering?  Refunded - depends where your bought it from.  Best buy refunded my entire purchase. Good luck.

Stupid me - I intailly blamed by ISP .. didn't return in within the 30 day period.

NOW --- I'm stuck with the god dam router.. I can't return to best buy

Going through this forum, there is MANY MANY router reporting the same issues WAN limited to 500 MBPS

Can someone at netgear wake the hell up .. 

here is example 

If you bought it at BB then you might want to try to return it by telling them the whole story and see if they would refund it.  Worth a try.  Depending on how long ago you got it might also want to check with our CC company to try.

I don't think best buy should not be losing money, and take back the device, there is something WRONG with the product. the manufacture needs to own up.. and find a solutions.

I purchased it in Dec 2019

I am way past 30 days, wasting to much time hoping for a solution.

Got mine at Costco, I will see if they will take this one back.  I already sent the first one back, so they should understand this product is garbage.

I finally fixed my problem :)

Final Results, I'm getting FULL 940 to 985 MBPS download (From Internet & Internal NAS Drive) - both in wired and wifi mode.

PLEASE NOTE** All my clients are wired or AC or AX devices.

Step 1 - Get the latestest firmware 

Step 2 - Turn OFF QOS

Step 3 - Turn OFF Traffic Meter

Step 4 - Turn OFF Access Control

Step 5 - Test you MTU from a wired connection > https://kb.netgear.com/19863/Ping-Test-to-determine-Optimal-MTU-Size-on-Router

Step 6 - Adjust your MTU settings >> https://kb.netgear.com/24015/How-do-I-change-the-MTU-size-on-my-Nighthawk-router

Step 7 - Use WiFI Analizer - FIND THE BEST CH for WiFI - I put AUTO for 2.4 and CH36 for 5ghz 

Step 8 - ENABLE BEAMFORMING > DISABLE MUMIMO > ENABLE AX

- So there is couple of other things i did, like use non netgear NTP server.. not sure if that even matters

Just wanted to chime in for any lurkers, this solution WORKS. The issues seem to be tied to steps 2-4. Everything was back up to about 1000/1000 after I changed these settings. 

Thank you for the solution mayeen12
