Picked up a RB2011UAS-2HnD-IN recently.
Item booted and I updated the OS to 6.14 then most recently 6.15.
Noticed that ether 3, 4 and 5 were not working for 100 Mbps Full Duplex (or Half-Duplex) devices. Thought I had a problem with the auto-negotiation tried hard setting the ports, with no success on obtaining any link on the ports. Tried a Gb device (only have two devices with GB interfaces - Desktop and Cable Modem) and ports 3,4 & 5 still failed.
Tried reset configuration. No success in getting a link on the ports.
Decided to try and downgrade to an older firmware to see if that would fix whatever I may have messed up on the unit (assuming that it was likely something I had done to mess up the device.
Last night I flashed via terminal 5.26. Doesn’t seem to have fixed the issue, and has brought about new issues. (As an example the unit shows a secure wifi yet it doesn’t accept my wifi password nor any that I could think it might be) This was after a reset that should have cleared any password i thought?
Would like to flash the unit back to 6.x but am limited in knowledge and equipment.
Understand I could use Netinstall to push the file, but I’m running a MAC at home (hackintosh)..
So the question is/are?
Can I install the OS from a cmd line via telnet, ssh…?
Can I place the OS (6.13 or 6.14) on a USB key and access that on the device via terminal to do the install?
As for the ports not linking can anyone suggest what may be going on?
Opinions as to what OS version should be used for stability and basic Home AP would be welcomed.
Much Thanks
Borrowed some time on a Windows machine and have the unit back at 6.14
only question remaining is what could be happening to ports 3.4 & 5
Do you get link lights on the problem ports?
Just for fun, try running “/int ethernet enable 2,3,4”.
Does “/int ethernet monitor 2,3,4” register any changes when you plug or unplug devices into those ports?
While writing this answer, I just found one of my ports, ether5, only advertising 10Mbps rates. Setting it to only advertise 100Mb and 1Gb rates led to the expected 100Mbps link. Enabling all rates then worked just fine for me. I suspect that ethernet cable, outdoor running up a tower, may be having issues.

Are there any entries in /log print related to those ports?
Did you reset your configuration to defaults after upgrading to 6.14?
Sometimes switch chips go bad. Hopefully that is not the case. But, unless there is some config problem, bad switch chip sounds likely. We can decide if we need to look at the config after hearing about whether or not we get any reaction to physical events and what those reactions are.
what gear do you connect to the ports not working properly?
thx for the replies and suggestions.
had tried numerous devices (Hackintosh that works on port 2 at Gb as well as Broadband Cable modem that works on port 1) Also tried another RB2011 unit that a friend picked up to see if the port would link between them (that failed as well).
for the test now i used a Picostation M2HP
Do you think you can have a source of Electro Magnetic Interference close to the RB? I only saw that happening on long cable runs and on installations on big telecoms towers.
Also check the grounding, try connecting the board to the grounding system or power it with a Ubiquiti POE - that has grounding and EMI protection.
Alternatively use ferrite filters, but I bout it’ll make a difference.
Maybe forcing the ports on both sides…
If all of the above doesn’t help you sorting it… I’ll give up… it’ll look to me as a dodge hardware.
cheers
I initiated a return to the vendor yesterday. They had shipped me a UAS model when I bought a UiAS unit. I could have lived without the POE out on port 10, however I would have preferred the feature to power a NSL M5….Still I wanted to make sure that the device was not working as i thought it should prior to returning it and getting the UiAS model.
Cable runs not really a concern (PSM2 POE injector was connected for this test on a 6’ Cat5e cable). Had tried numerous power sources (home and a friends house (his RB2011 works fine).
Will return the unit to vendor by mail today….Hopefully I only have to rerun to the forums to answer questions at some future date hahaha….I doubt that though…..more likely that in some sleep deprived state I’ll post that someone stole my token and nothing works
