Unknown glitches with routing

Hi. Yesterday started the problem: 2011UAS-2HnD Large ping and packet loss to internet. It is impossible to work, winbox disconnects every 30sec. Web pages don't load.
Mikrotik gets WAN ip and default route via DHCP.
white ip- *.184.101.224
default gw- *.184.101.1
Firewall is off, latest firmware.

[admin@MikroX] /tool> traceroute 93.158.134.3

Traceroute very strange, the first step should be my default gw- *.184.101.1 but its empty...
The most interesting thing, if I connect a cheap home router - Internet works fine.

Check if you have a DNS attact on port 53

Thank you! it was an attack. Reconfigured the firewall, closing incoming ports. Now everything is OK
