Quote from: SteveInWA on March 31, 2019, 09:15:34 AM...you are posting in a five-year-old discussion that is no longer relevant, as it was about the now-discontinued 100 series. The current models are 100Mbps full-duplex by default.
This thread doesn't mention any model numbers, but
the referenced thread mentions Obi100, Obi110 and Obi202. Though about seven years old, the Obi202 is still a current product.
I found this thread because I have a situation where I
suspect that I'm getting only a 10 mbps ethernet connection, most likely due to a problem with my TP-Link router. But, frustratingly, neither the modem, the router, nor the Obi will tell me what speed they're actually running on their Ethernet ports. (My Obi is a 202.)
The Arris SB6121 modem comes closest. It shows a blue status light for 1 Gbps speed, or amber for 10 Mbps or 100 Mbps. The light is amber, but that doesn't tell me whether it's at 10 or 100. (Tellingly, if I connect the router directly to the modem, with no Obi202 between, the light is still amber, and it
should be blue, because both the modem and the router are supposed to have 10/100/1000 mbps ethernet ports.)
Nothing
should be running half-duplex anymore, but it occurred to me that if my router is negotiating the wrong speed for its ethernet ports, then it might also negotiate the wrong duplex. (Or maybe not -- I'm not an expert on this.)
