To begin with, I will try to describe to you the scheme

  1. An Internet cable comes to the apartment and is connected to MikroTik hEX RB750Gr3 (hereinafter referred to simply as MikroTik);
  2. There are several cables from MikroTik. For example, to the router (Keenetic Giga II) and PC.

After purchasing, unpacking and turning on MikroTik, the maximum that has been done is the initial setup with the input of IP, gateways and so on. Then I connected those cables to the output and no longer returned to MikroTik.

On the PC and on the router, one problem is noticed - interruptions (not frequent, but there may be several of them on a day). A router that distributes Wi-Fi, in general, can periodically die due to one such interruption (either it stops to “see the Internet”, or just seconds for 10-20 will fall into a stupor, or something else like that). By the way, the PC has a similar situation - the Internet disappears for a few seconds (approximately 10-20), and then everything is fine again. Apparently the problem is identical with the router and PC, just the PC will be stronger, and the router may die and will have to restart it.

Tell me, please, what does it look like? How can this be cured? I have never come across this and can’t even figure out what could be the matter. The situation is critical.

  • @ Problem196 understood. How can I catch the problem again - I will take the logs for this period and post it here. - Colibri

  • @ Problem196 was just crashing. I went into the logs of MikroTik - there is nothing there. The last two lines are May / 13/2018 01:38:38 and May / 13/2018 18:33:18. The latest is authorization in the web interface. The failure was just at 18:32 - 18:33. That is, there is nothing in the logs ... - Colibri

  • @ Problem196 so vsmysle. I have MikroTik, yes a PC that is connected to it. Where else? The PC just disappears Internet. On the cable, it simply does not (a few seconds). - Colibri
