CM1200 w. Port Aggregation = no 192.168.100.1 access?
Question - Is there any way to test performance or see monitoring of CM1200 if using port aggregation?? Trying to complete a setup of the following: Comcast Xfinity 1200mbps - CM1200 - port 1/...
You'll not see anything more that 1000Mpbs thru the Orbi when wired. Due to the LAN ports on the RBR and most current ethernet adapters are limited by 1000Mpbs LAN port speeds.
For wireless, If you have a 4x4 MIMO AX supporting device, you may see over 900Mpbs on wireless thru the Orbi and CM1200 when in LAG mode however in most cases, 900Mpbs would be a max speed. Most phones and pads are 2x2 supporting there there max limites are usually around 500-700Mpbs. I have a ASUS GT-AX11000 and a NG-RAXE500 that in bridge mode would be able to see speeds over 900Mpbs on wifi.
Technically for wired speeds, to get anything over 1000Mpbs, the WAN port and LAN ports on the router and modem and ethernet adapters would need to support 2.5Gb ports. Modems like CM2000, CM2050v, CAX80 and Orbi RBR850 or a RAX series router with higher speed ports. I currently have a 2.5Gb PCI ethernet adapter in one of my PCs. I have a USB C to 5Gb ethernet adapter for testing on my Mac.
Are you saying that Port Aggregation on the CM1200 and ORBI750 does not work?
With Port Aggregation the two pair of connected Ethernet ports should provide 1G+1G for a total capacity fo 2G. There can be a very small amount of packet reordering overhead that decreases that a bit, but it definately should be close to 2G when configured in this fashion.
LAG works on the WAN side however you'll not see anything on the wired LAN side as the ports there are only 1000Mbps. These top out at around 900-950Mpbs.
For wireless, if you have a good solid 4x4 MIMO 5Ghz AX supporting devices, then I beleve you could see over 1000Mpbs on 5Ghz AX if the connection rate between the RBR and this device was at 2400Mpbs with LAG enabled.
If I'm understanding you correctly you are saying that the connection between CM1200 and RBR750 does not support LACP-IEEE 802.3ad Port 1 & 2 to create an aggregated ethernet between the CM1200 and RBR750?
If so, that's really quite poor design / implementation.
It also directly contradicts what Netgear support stated.
FYI...
900-1,100 Mbps from back of CM1200 after Xfinity tech did the necessary.
That turned out to be.... cleaning the dirt from the connectors of the newly installed/ buried outside cable.
Already had good SNR but now the power is looking better per CM1200 admin (Netgear genie).
So at this point I'm about to bag even trying to use port aggregation for the 10+% performance increase at times.
Still it would be good to know if others have had this experience with port aggregation.
It would seem like it's possible the the monitoring software of WAN link (Internet) on the Orbi has a deficiency with respect to calculation when port aggregation is used, OR, that there is an underlying deficiency in the port aggregation implementation on either or the combination of the Netgear CM1200 and Netgear Orbi RDR750.
