RB2011 & RB493G: GigE ports not working with specific devices

RouterOS General
1

I have 2 different Routerboards (RB2011UiAS-2HnD and a RB493G). The 2011 is my primary router/AP, the 493G is a backup. I am having an issue with GigE not working between the Routerboards and 3 different devices: 5-port Gig switch, 8-port Gig switch (both TRENDnet) and a Pace 5268AC router. GigE works perfectly with my PC’s (various desktop and laptops), GigE works if both RB’s are connected to each other.

I recently had Gigabit internet (AT&T fiber), so now not having gigabit all over my LAN is an issue. I have tried different cables (Cat5e and Cat6) over various lengths and have also make a crossover cable. The Routerboards simply will not negotiate to 1GB.

Any help would be appreciated, thank you!

I have tried this now with a different 5 port Gigabit switch and have the same issue, will not negotiate to 1Gb. All of the PC’s and laptops I’ve tried do negotiate to 1Gb.

Is this an issue with Routerboards in general?

Can anyone recommend another model Routerboard that would work? AT&T’s router is pathetically terrible and I would love to have my Routerboard back to running again.

Have you tried set force this?

interface ethernet set ether5 advertise=1000M-full

Sorry for the really late reply, I’m just getting back around to this.

When I run that command, that port loses connection and cannot negotiate with the AT&T gateway.
