Orbi Throttling Wired Ethernet connection
I noticed this morning that our RBR40 seems to be throttling our 200 Mbps Interenet speeds down to about 90 Mbps on the wired connections around my home. Wifi is at 200Mbps+. I did separate multiple...
ekhalil FURRYe38 , After borrowing a thunderbolt to giagbit adapter, a usb-c to gigabit adapter and a very long cat 6 cable, I think I was able to determine that there may be a problem with the CAT 6 cable running from the RBR40 to the jack in my office. I connected the long CAT6 directly from my RBR40 to my Imac and got full speeds and 1000baset hardware. I connected my Macbook to the RBR40 and got full speed. I then connected my Macbook to the jack in my office and got 90mbps and 100baset hardware. I'm going to change the connector on the old CAT 6 and see if that restores full speeds. In the mean time wi-fi gives me full speed.
Bielski, not sure if you saw my post above and tried it, here it is again:
1) The fact that you'r getting speeds on the limit of the 100BASE-T speed makes me think that this can be a wrong setting in the iMAC, Please check iMAC settings under >> System Preferences >> Network >> Ethernet >> Advanced >> Hardware >> then check what you have there. You shouldn't have 100baseT. Try also to set it to Manually and 1000BaseT / Fulll Duplex and see if this changes anything, as you can see below:
2) Please also try another LAN port on the Orbi, it can be a bad pin 8 on one of the ports?

A continuation of this post, please try the following settings in your iMAC:
System Preferences > Network > Select Ethernet on the left side > Select Advanced > Select Hardware Tab
Change settings to following:
Configure: Manually
Speed: 1000baseT
Duplex: full-duplex, energy-efficient-ethernet
MTU: Custom - 3000 and above
AVB/EAV Mode: Checked
I tried manually setting the Hardware and I got a cable unplugged and lost my ethernet. I will try changing ports and see what happens.
Let us know how it goes.
FURRYe38, ekhalil, here's what I learned today. I did a speed test using my PS4 connected to a gigabit switch connected to a different port on my RBR40 on one end and another gigabit switch on the other that also feeds the 100Mbps Apple TV, and a DirecTV Genie Mini in another room. The PS4, which is 1000baset was averaging about 180 Mbps. I pulled the iMac newtork cable off of the RBR40 and plugged it into another port on the gigabit switch. My iMac is now getting 230 Mbps again. This makes me believe that there is definitely something wrong with the RBR40. I reached out to Blanca_O, supplied her with all my information and I'm waiting to hear back from her tech support team.
