Slow network performance on AX50/AX3000
Hello, I just purchased a AX50/AX3000 router and am having a terrible time gettingt the LAN speeds to be good. My other router was a Netgear and I was able to confirm that my WAN/Internet speeds are 500/250 from my ISP. I am getting close to that on wireless when I am right near the router. However, with the AX50 I am only getting 60mbps down and 40mbps up. I've tried everything including mimicking my settings from the Netgear router. Could this be an issue with my devices (iPhone and Macbook Pro) not supporting AX?

I have seriously spent half a day trying to get a new AX50 to perform as it should with absolutely no success. My old Netgear router was getting a little flaky in terms of dropping clients, so I tried to swap it out, but this AX50 is incredibly slow and none of the QoS, Tether, or other suggestions here seem to be a factor since I have done multiple factory resets and tried literally every combination of settings to improve results. Even wired speeds are a fraction of what I had on the Netgear.
Netgear speedtest results: 482 down / 22 up wired, 206 down / 22 up wireless
AX50 speedtest results: 92 down / 22 up wired, 91 down 22 up wireless
Some factory resets would temporarily get the speeds up by maybe 50%, but they would drop within minutes. What's worse is that real world usage seems to be exponentially slower than those speed tests indicate. Connected to the AX50 wifi, trying to download and install the tether app takes anywhere from 5-12 MINUTES. It's a ~50mb file!! Installing over the Netgear wifi finishes in under 10 seconds. The AX50 also struggles to load social media feeds. Facebook groups on my phone is like a 2-3 minute wait to refresh and sometimes won't load at all. Switch to LTE and it comes up instantly.
At this point, I don't see how it could be anything other than a hardware issue and I'm shocked that this router gets as much praise in online reviews as I've seen. I may try to exchange it with another unit, simply because there's no way this can be the norm, but it's definitely concerning to see so many other people having performance issues.

UPDATE: This thing is garbage. Received a new router yesterday from Amazon and it is having the same problems. Facebook and other social media apps absolutely will not load properly over Wifi. It's as if QoS or parental controls are enabled, but they are not. It is blocking that traffic right out of the box with factory settings. If I turn off wifi and switch to LTE, everything loads instantly. Going to have to switch to a different brand, I guess.

I ended up returning my AX50 and going all-in on the ASUS Zenwifi AX mesh system. So far it works beautifully; much faster speeds, coverage, and customization.

OK, in another thread, someone suggested enabling IPv6 on the router in order to fix loading issues in social media apps. Amazingly, this seems to have fixed most, if not all, of the issues I was having despite the fact that I never enabled IPv6 on the Netgear router I am replacing.
HOWEVER, this did cause a new problem in that Netflix was not working on any LAN ports. By default, the AX50 has IPv6 set to SLAAC for LAN. Switching this to DHCPv6 seems to have fixed the Netflix issue. Cautiously optimistic that this will be the end of all this nonsense and that everything is working now. I still don't trust this thing 100%, but I really don't feel like returning it again and starting over with something else.

@PETzz agreed. I had one device in my QoS prioritized and it knocked all my other devices to half the speed of my internet which was 250 Mbps out of 500 Mbps. Thanks for the tip PETzz.

So is the AX50 not a good buy as in prospective buyers should stay away?

@Linsook I recommend you the little brother AX20...

I ended up getting it running semi-decently after literally two days of fussing with it,, although the speeds could still really be up and down. It seems to get great reviews everywhere, so my experience maybe is not the norm. One thing I can say without a doubt though is that it runs EXTREMELY hot. I measured the case at 136F after running for maybe 10-15 minutes and under almost no load. I moved it on my desk and the spot where it had been sitting was almost too hot to touch. That was the last straw and I ended up swapping it out for an ASUS AX58U, which seems a little slower at long distances, but overall has been a way better experience.

I managed to fix this issue! The router runs HOT, if you pick it up the underside is extremely hot. This router has a massive design flaw of having the tiniest vents, non-existant feet, and the plastic material that essentially acts as insulation. Simply elevating one side will help airflow immensely. I'm purchasing an active cooling fan to lower the temps even further. good luck everyone!

@Sevi i having the ethernet speed issue, my ISP was 500Mbps, but using lan port only can get 300Mbps. I also set the bandwidth at QOS with download speed and upload speed with 1000Mbps is more than enough but still the same getting 300Mbps only, for upload ok no problem. any solution to me ?
