ATT BGW320 and Orbi750 Negotiating 100Mbps
Hi Guys, I connected BGW320 that is in my garage to a Orbi750 using a 100m long ethernet cable and I see that they are negotiating to 100mbps. If I connect the same cable to my laptop I see t...
Another crazy thought: If that laptop will maintain a 1000Mbps link for a substantial amount of time**, what about connecting to an Ethernet switch in front of the RBR750? The electronics built into Ethernet interface modules may be slightly different from one device to another.
i.e. where the Ethernet cable arrives at the RBR750, connect it to an Ethernet switch on one port and connect another port to the RBR750. With nothing else on the switch***. The RBR750 will negotiate 1000M/Full with the switch. If the BGW320 also negotiates 1000M/Full with the switch, then "problem solved". Total investment: under $30 and an hour of time.
** If the laptop also drops the link speed to 100M/Full after some period of time, the issue is moot.
*** This depends on the "mode" of the BGW320 and the Orbi. If the BGW is in the default "router mode", then it has created one IP subnet LAN, and the issue becomes what mode the Orbi is in. If the BGW320 is in "pass through" mode, then for certain nothing else can be connected to this switch.

Thank you Guys, esp CrimpOn. I placed a Netgear switch close to the ATT BGW320 and connected it back to Orbi750. This seems to have solved the issue.
I agree with Schumaku. It looks like this could be a speed negotiation issue between vendors, and also, maybe the cable length is coming into play.
