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.
So your only getting 80Mbps with a wired PC directly behind the modem? This would not be good. Do you have another wired PC to test with the modem directly? Either the network adapter on this PC isn't getting 1000Mb connection rate at the modem or it's getting 100Mbps which would result in what your seeing with 80Mbps with a wired PC at the modem.
So this is possible a bad cable, bad adapter on the PC or not configured correctly or possible bad LAN port at the modem.

Do you have any video or source that help me to config the modem or the router properly? I don't think I can't login the modem to config anything.
192.168.100.1 is the only IP address I can access as the screenshots.
Either 192.168.1.0 or 192.168.1.1 or 192.168.0.1 are unable to accessed.
- I would look at the ethernet cables you're using, that may not allow over 100mbps. What ethernet cables do you have?

- Are you able to try a different modem to the one you have to see if you see the correct speeds then?

- Perhaps ask the ISP if they can change the modem. If possible you could buy one, test it and then return it, if it works then ISP should definitely replace the modem.
What modem do you recommend? I'm using Spectrum now.
- We don't have any specific ones that we recommend, as long as they can support the speeds from your ISP then it should be fine. Other users here may have some suggestions.

Sounds like your device likes to connect to 2.4Ghz rather then 5Ghz when Smart Connect is enabled.
Glad you got it working. Thanks for letting us know.
Enjoy. :smileywink:

It's weird that all devices connect to 2.4Ghz rather than 5Ghz although they are 5Ghz capable.
Whatever, it was a experience and a way for people who are struggle, troubleshoot their router.
Thank you for your support.
Enjoy.
