I was experiencing issues with my 2011UiAS-2HnD and RouterOS > 6.19, after upgrade and try almost every single version further 6.19 it started to gain a lot of delay. I wasn’t able to do a simple ping, it returned almost always, a no route to host, but some times it worked but with a latency higher than 2300 ms. I don’t know why this happened, but I’m posting this issue here to inform to RouterOS team about the issue and get it fixed.
P.D. Just after reboot my router, I did a ping and it worked fine, but after a minute the issue appeared, this happened with all RouterOS versions that I tried with a version higher 6.19.
First, the issue is back with 6.19 firmware, then yes, I used the reset to default command from the router to reset command and I did the configuration from scratch. The last that I tried was to reset the router configuration by using the reset button and configuring from scratch, but the problem persists.
I don’t know what is happening, this appeared suddenly without notice and is very annoying, because my bandwith is trimmed. I don’t know what to do to solve this issue.
