RAX15 AX1800 Internet speed only peaks at 300mbps

[mpe2903]

Hi,

I have a similar issue as described here: 
https://community.netgear.com/t5/Nighthawk-Routers-with-WiFi-6-AX/RAX15-AX1800-bottlenecks-my-intern...

This did not solve my problem however.

• I removed all the settings as described like QoS, etc
• Factory Reset
• Rolled back firmware and then restored the latest.

I have a gig connection but I can never get more than 300.  Right now i'm at 100.

I think at this point I was sold a lemon but i'm hoping theres a resolution that doesn't include me buying a new router.

Thanks.

You have an RAX15. 

What firmware is on it? 

What modem/gateway are you connected to? 

How are you testing? Wired? wireless? 

What website are you testing on?

My Router: Nighthawk RAX15

Firmware Version V1.0.2.64_2.0.42 Arris SB8200 modem.  980mbps down direct connection. wired and wireless with multiple devices  xfinity speed test, speedtest.net

What port on the SB8200 are you connected to? 

Make sure its port 1 and nothing else is in port 2. 

have you tried a different cable between modem/router? 

After you reset the RAX15, did you ever speedtest it with it running in default configuration? without changing anything in settings? 

I'd try this.

• Port 1 on the SB8200
• Swapped cables
• Speedtest after factory reset 

Same result

I usually don't say this (and not sure if rax15 has this) but have you went into the dynamic qos and manually set your speed?
