Slow internet on VB Kali Linux with network bridge?

Question

Computer networks

Hello. There was such a problem:
Kali is on VirtualBox 6.0, I have a cable Internet, NOT via WiFi, because of this, probably, all the troubles. There was such a need for the Internet to be configured through a network bridge, i.e. so that I can work on a virtual machine on the Internet bypassing the host system, directly, so to speak, back and forth ..
I have 2 adapters: RealtekPCIe GBE Family Controller and D-Link DFE-520TX PCI Ethernet Adapter.
All the time I sat through the 2nd one, and when I redefined the connection type to the Network Bridge, then the Internet disappeared on VB, then I plugged the cable into the 1st adapter, launched VB, the Internet was, but so slow that not a single site loaded. Nothing was loaded on the host.
In general, who faced this, share the decision, I will be grateful.
Thanks in advance and good luck to you!

If you omit your grammatical errors, it is still not entirely clear - what is the question? You started with "A", finished with "B". Everything was mixed up in a heap - adapters, connection speed, and availability of sites. Could you express yourself a little more clearly?
And of course, if the issue is connection speed, we a priori believe that you understand the difference between VirtualBox connection types - then do you know how NAT differs from a network bridge?
