MA2500D massive random packet loss

I just upgraded from 4x WF-803M to 4x MA2500D.

Using the 4x WF-803M, had no issues.

Now with the 4x MA2500D, I get random drops... with no real rhyme or reason that I can tell.

I did a 100 ping test several times successively... a couple of the times no issues, a couple of the times 7% and 8% loss, a couple of the times 30% and 38% loss.

The adapters are directly linked in pairs:

switch<--->ma2500d<--->coax<--->ma2500d<--->switch

so there is no interference from anything on the coax part, especially given that the WF-803Ms worked perfectly.

I see another post about disabling EEE... however, even if that IS the problem (which I'm not sure of) I can't do that on my switches.

I did update to the newest firmware on the support page: v2.0.11 but it didn't seem to fix the issue... I did a couple of tests after and I was still losing packets.

I need some kind of a firmware fix or a way to configure something on the adapters themselves to fix the issue.

Before i did not read this type of blog, but you informed me about yours, so I went there and learned something. Since I enjoy reading blogs where I learn things, I'll now share my own with you. I'm providing details. The Houston Astros Jackets are a terrific jacket with a large selection, low cost, and pricing.

I have exactly the same problem and I was not able to find a solution for it then I read your blog and I got a lot of help in solving this problem and your blog is very well written and I liked it. 's blog has proven to help, now I am telling you that if you want to look good in this winter season, buy the Coachella 2023 Billie Eilish Jacket now, which is at a very low price.

@CWhiz Do you still have the old WF-803M? I'm curious why the upgrade?

So I've "fixed" my problem...

After doing more research, it turns out that the "dumb" switches I have already don't support EEE so being unable to disable the setting on them wasn't necessary... but one of my Dell switches had it turned on.

Turning it off on that switch seems to have fixed the issue completely, at least so far.

I guess disabling EEE is okay as a workaround, but there really should be a firmware fix.

@goCoax Not sure if I need to ping to get your attention or not, so...

We are checking your issue. Could you share the model number of switch?

Could you try a beta firmware? If so, please leave your email.

Currently I have it like this:

I did test it with a couple of other "dumb" switches, but since they have EEE, I get the drops with them as well... I can give you the model numbers of the 2 other switches I tested if you want.

I had to disable the EEE (called "Green Ethernet") on the Dell X1026 switch that had it enabled in order to solve the issue.

I'm willing to test beta firmware, in the interest of not getting spammed by publicly posting my email address you can email it to dueltmp+iqdj2@gmail.com (or the one on my profile here).
