Hello Mikrotik

im using 5.2 and i got this logs :open_mouth: the rb750gl connect to a ordinary Ethernet switch hub (intex brand), why i got this problem its only a normal hub i think this is a port flap. but if i direct connect the laptop to rb it work!!. can i downgrade to 4.17 possible?

@Toiletbowl

If your RB works fine connected to your laptop, and there is a issue when connected to switch, the answer is only one:
Change your switch and buy something better than ‘Intex’.

HTH,

I’ve had some customers experiencing ‘slow’ Internet connectivity with specific types of dsl or docsis modems. Strangely, the same hardware works fine in 4.17 but not in 5.x.

@ditonet

i try to change dlink switch same issue dude and also i borrow cisco SF 300-24P same as well.

Happy New year

I have some routerboards hooked to cisco gear that do the same thing.

4.17 does not have interface state logging. So of course 4.17 is “better” as it does not show these events to occur. You can ignore them in 5.x releases and it will be just the same as it was in 4.17.

10

They weren’t experiencing interface flapping, they just said throughput was slower with v5. I haven’t verified it and I don’t know if it’s related to the problem being discussed here, but I thought I’d pitch in since it sounds similar
