Getting slower speeds when connected to the main Deco than when connected to other units
Devices that are connected to the main deco, are for some reason getting much slower speeds than they should be, and slower compared to when connected to the satellite decos. I have 2 Gig internet, but I understand I won't get that over WiFi plus most of my devices don't support it yet. (Getting 1 gig is only five bucks cheaper)
The devices connected to the main deco get on average of 350-450 mbps down (at 5-6 feet away). However, devices that are connected to other deco units throughout the house could get over 650mbps, consistently. I dont think it's an issue with the specific device(s) because I've tested it all. You would think, being connected to the main deco, would give you the better speeds.
I can unplug my Deco and hookup my older ASUS RT-AX86S Router in the same exact location of the main deco, and will get 750-800mbps down on the very same devices that are getting lower speeds when connected to the main DECO, which is the standard.
Again, there is no issue with the other two deco satellites throughout the house, and speeds are consistent.
For context: when connected to my ASUS router, I'll have Tx Rate of 1,300mbps according to my WiFi expanded details, but only 780-876mbps when connected to main Deco, all on same devices.
Here’s what I’ve already tried to resolve the issue:
- Ensured firmware is up-to-date
- Hardwired main Deco into my computer, and got max speeds as needed. (so no issue there)
- Rebooted and unplugged all units multiple times
- Optimized the network repeatedly
- QoS is not enabled
- Switched between 80 MHz and 160 MHz frequencies
- Erased devices in the Deco app and forgot the WiFi network on the devices
- Switched Deco units to test different ones as the "main" connected to the gateway
- Tried using AP mode (since my ISP’s gateway is not in bridge mode)
For further context, I’m using an Xfinity modem/router that’s not in bridge mode. I understand this might cause interference or double NAT, but so far, the Deco XE75 has outperformed the gateway throughout other places in my house. Plus, when I connect the older ASUS router, speeds are excellent.
Any suggestions or feedback would be greatly appreciated!
Thanks!
