Fast LAN/Slow Wifi on XR450
Hello,
I have a XR450 wifi router connecting to the Arris modem provided by Spectrum. I checked and compare the speed on various sites. When I test my computer by hooking up wired LAN, the speed is around 90 Mbps. However, when I switch it to WiFi, it is only 50 Mbps. Everything setup with default settings. Do I need to do anything in the settings to twist the performance? I did updated the firmware, factory reset but those methods didn't work. Please give me advice.
Thank you
I finally found out the reason!
I didn't setup 2Ghz and 5Ghz radio frequency separately. Now when I connect to the 5Ghz one, I got over 200Mbps. With the 2Ghz, it is only 50Mbps at best. Didn't think that it is not automatically switch radio.
Thank you for all your helps.

Wirelesss speedtesting is hard to judge. Its good for an inicator but so many factors can influence speed from housing materials, wireless interference, bands you're broadcasting on, device you're using, and even the firmware on your router.
What band are you connecting to? The 2.4ghz band has lower throughput but better range and penetration. The 5ghz has much higher throughput but won't penetrate as much or go as far. The other though is the 5ghz has the option of the DFS channels. Not all devices support these channels so if you're using them, your phone/wireless device might not be.
And how are you testing? (aka what device and website are you testing with)
Firmware on the router?
More information:
- I tested on wired/wifi (Arris Modem TM1602A provided by Spectrum/XR450) on various devices (Laptop, Galaxy Tab S4, Iphone 8, Samsung S9, Macbook Pro 2018) run on both 2.4 and 5.0 Ghz
- Firmware version V2.3.2.56 (Up to date as it stated)
- Ipv6 disabled
- 9 Neighbour wifi around
- Beamforming and MIMO and WMM enabled.
- Channels Auto
Updated:
- Interesting thing is I ran the Wizard Setup on XR450 and it perceived the down speed is 213.5 Mbps. Also confirmed with Spectrum representatives that their test speed on Modem also around 210 Mbps.
- However, the real speed tested on multiple devices I mentioned are still 40 Mbps down for Wifi, and 90 Mbps down on wired modem itself. Up is around 11 Mbps on both.
- Spectrum asked me if I want a technician to come to take a look. If there is no issue on their end, they will charge $50. I refused because it is ridiculous.
Do you guys have any idea? The Netgear XR450 wifi router perceived the speed is 213.5 Mbps down, but real speed is much slower on both modem (wired) and XR450 router (wireless).

What Firmware is currently loaded?
What is the Mfr and model# of the ISP modem the NG router is connected too?What speeds UP and Down do you pay for from your ISP?
What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?Try enabling Beamforming and MIMO(MIMO may or maynot be needed) and WMM.
Try disabling the following and see:
