Does RB435G's Gigabit Ethernet REALLY WORKS???

As tittle says.


I encode a LOT of problems with their (5 of them) Giga Ethernet connections.

Details:

I have a MiMo config with 4 of them.
ROS 5.24.
Nv2
5GHz-only-N.

A goes wireless to B.
B is connected through C with a Giga switcher.
C goes wireless to D.

ALL of them are manually “locked” at 180/180Mbps and ALL have 100% CCQ Tx/Rx.

Now

Bandwidth test from D to A, shows 18.5Mbps TCP with 20 ports and COPY a file from D to A, reaches ~5.5MB/s.
Bandwidth test from A to D, shows 9.5Mbps TCP with 20 ports and COPY a file from A to D, reaches ~2.5MB/s.
PING for A to D and from D to A, FLACTUATES a LOT from 1ms , 32ms, 4ms, 16ms, etc.

ALL connected at 1 Gbit.

Now.

I MANUALY “downgrade” the RB435Gs Ethernet speed at 100Mbps by UNCHECKING the “Auto Negotiation” and…NOT EVEN the winbox program can “see” them, NOT to say about the computers that they are connected on. :frowning:

I then “MANUALY downgrade” the Ethernet on BOTH end computers at 100Mbps full duplex AND put “MANUALY fixed LAN cables” with "wrong made cables - blue/white and green/white putted OPPOSITE - , from B to switcher and from switcher to C and they Auto Negotiate and lock at 100Mbps full duplex and I got the following results:

Bandwidth test from D to A, shows ~64Mbps TCP with 20 ports and COPY a file from D to A reaches ~11.5MB/s (the MAX the 100Mbps the Ethernet can do).
Bandwidth test from A to D, shows ~64Mbps TCP with 20 ports and COPY a file from A to D reaches ~11.5MB/s (the MAX the 100Mbps the Ethernet can do).
PING for A to D and from D to A, stays ALWAYS at 1ms and once in a while 16ms (I don’t care).

I HAD to leave the RB435Gs on “Auto Negotiation” config and NOT touch/change it and I HAD to put ALL other config (computers/cables) at 100Mb, to work properly.
IF I touched EVEN ONE RB435G and UNCHECKED the “Auto Negotiation” config to work it with 100Mb, I was f(l)ucked!! :frowning:

SO PLEASE tell me: DOES the Gigabit Ethernet on RB435G REALLY WORKS OR I have “through away my money” instead of buying something cheaper with 100Mbps Ethernet (which apparently with the RB411AH and their 100Mb, I didn’t encode such problems)?

Yea the gigabit should run full gigabit.

The Ethernet status tab will tell you if the router port is running at 100 or 1000

I would not recommend locking the wireless to 180. That means it won’t be able to modulate down when needed. You should be getting much better speeds the your reporting so I suspect a configuration or hardware issue. I have found that the modulation selection with nv2 has been great.

I don’t generally have much issue running 100mbps with a 20mhz channel even over 5 miles away. I have had to manually set the interface speed and turn off auto negotiation due to other equipment not playing nice. I have mostly seen this with sonic wall firewalls.

I left it at autonegotiation and my computer’s lans at auto too…When it locks at 1Gb, problems are starting to show off.
I lock at 180Mbps AND ALL below. :slight_smile:
