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 ...
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).

Can you confirm that your getting to spec speeds via wired PC?
Is Smart Connect enabled on the XR router?Was a factory reset performed after last FW update and setup from scratch?
Seems like this is a XR wifi issue and not a ISP or Modem issue if wired speeds are good.
Yes the test is performed on both wired and wireless.
Wired directly from the modem. Wireless from the XR450. Both slower than what they should be.
The Smart Connection enabled.
I factory resetted after FW updated. I check FW update again and it is up-to-date.
Is QoS enabled? If so, disable QoS and Anti BufferBloat and save the setting, reboot both modem, router and PC and test speeds again.
So at the modem you get over 200Mbps, and at the XR router wired you only see way less.
Can you check with your wired PC to see the connection rate between the PCs network adapter card and the XR router? Should be 1000Mbps
