RouterOS v7.2rc1 Router’s model RB5009UG+S+in I have a 1000Mbps downlink connection to my ISP. When connected via the 2.5G link on port 1 to the ISP cable modem, the connection speed maxes out at about 500Mbps When removing the 2.5G negotiation speed on ethernet1 inside RouterOS and connecting t…

I had similar problems with a Realtek RTL8125B. Turning flow control on fixed the problem. For me, flow control was a completely separate issue but solved just general issues on my network with mismatch link speeds causing buffers to overflow. I’m trying some test builds from MikroTik, will re…

Three of the four test versions worked very well! Encouraging, I’m sure more to come soon from Mikrotik! I’ve restored to 7.2rc4 for now, not going to run those alpha builds :slight_smile:

They had me test the alpha firmware as well and it definitely clears up the issue. Woohoo!

They had me test the alpha firmware as well and it definitely clears up the issue. Woohoo! Did all work the same for you? One of them, the last one v4 seemed to still have issues on my side.

SergeP: I’ve tested all four 7.99’s. I use ether5,6,7,8 as LACP. I tried 1G and 2.5G on ether1. Looks like all builds do not increase speed above 1G in any settings. (Use different computers at the same time, It’s combined speed). 1G +2G(LACP) gives 450Mbits + 450Mbits - total < 1G V1: 2.5G - 9…

Same issue here. How can I request for the alpha firmware?

I can confirm I found noticed this just this morning on 7.2.1. I have gigabit cable service and my DOCSIS modem has a 2.5G ethernet port. Tests with 2.5G ethernet enabled get me ~600Mb/s. If I remove 2.5G from the ANEG profile I get 940 all day. I turned TX Flow control on ether1 but it’s not actua…

The 7.3 series works well for me with the cpu-flow-control on the switch. I’m running 7.3beta37 right now, and all is well for 10G, 2.5G and 1G hosts. Something to note is that I had a lot of problems with my CRS328 switch in RouterOS, Mikrotik has confirmed tx-flow-control does not work correctly …

I can confirm running v7.2.3 on RV5009. At 2.5Gb I get 500Mbs - 600Mbs When I turn it down to Gigabit I get full Gigabit around 930Mbs Any chance of a fix making it into the v7.2 branch while we wait for v7.3 to hit stable?
