Reduced Wired Download Speeds RBR 750
I was wonderfing if others using the RBR750 have seen significantly reduced wired connection speeds through the router. Our ISP is Spectrum Cable 1GB. When I do a speed test, it routinely indicates...
Update - A Spectrum technician came onsite today. Prior to his arrival, I ran additional speedtests and of course, everything was working beautifully with 800Mbps + speeds on the wired connections through the RBR750, which hasn't happened for over a month. He ran diagnostics and everything checked out. He also advised that there had been another issue in the area that Spectrum resolved yesterday, so it's possible whatever that was, it cleared what was impacting my wired speeds.
For now, I'll consider the issue closed. Thanks to those who responded with resolution suggestions!
One suggestion - Try running your speed tests using speedtest.net's website/app and do not rely upon the Orbi app or admin website's speed test. Then we can be sure it is not something to do with how Orbi is measuring speed.
It is a good idea to verify your wired speeds in this consistent way from your laptop wired directly to the modem vs. laptop wired to Orbi RBR wired to modem. That result will narrow down where the wired speed drop is occuring. I think you should be able to get close, e.g., 800Mbps+, with devices wired directly to your Orbi RBR (omitting any network switches or other hardware). Make sure you have parental controls, etc. turned off. What other settings have you changed, if any, from the Orbi default settings?
Wireless speeds will be limited by many other factors and will not be close to 1Gbps like you should be able to see with wired. I think your best devices with wifi 6, e.g, iPhone 11 Pro or later, will regularly see 400Mbps to 600Mbps under ideal conditions even if your upstream connection supports 1Gb.
I cannot explain why your laptop could not access the internet when connected directly to the Spectrum modem. Did it get an IP address via DHCP? Are there any MAC restrictions or configurations that need to be set on the Spectrum side or reset? I have Xfinity so don't know.
It doesn't sound like you have Double NAT but you can verify it by conparing your IP displayed by canyouseeme.org against http://orbilogin.com... Advanced... Internet Port... IP Address. They will be the same if you do not have Double NAT. If your Orbi's IP address is different, often something like 10.*.*.* or 192.*.*.*, then there is Double NAT. My Orbi's Internet IP address using Xfinity is like 73.63.*.*.
Thanks for the reply.
I have run many tests using speedtest.net and the results I indicated in my messages except for the speed from the modem to the RBR750 are the results from those tests. Unfortunately, I've been unable to run speedtest.net on the download speed directly from the modem as I'm unable to get the laptop to connect to the Internet when using an ethernet cable connection between the laptop and the modem. That's why Spectrum has dispatched a tech tomorrow to come onsite as I should be able to do that.
I didn't change any settings on the Orbi router from the default settings. They all remain as originally configured. If any changes were made, it was as a result of the firmware upgrade but I didn't make the changes. The firmware upgrade was done automatically while we were out of town.
I'm not technically proficient enough to answer the questions about the Spectrum modem. The laptop never registered an Internet connection when connected to the modem. I'll wait for the Spectrum tech to come onsite tomorrow to run those checks but when I was on the phone with their tech support, the individual I spoke with said on his end he was seeing things that indicated something is wrong so perhaps the settings for the modem are incorrect.
Thanks for the great feedback and suggestions. I really appreciate it. Hopefully when Spectrum is onsite tomorrow we'll be able to determine what's wrong.
