I have a strange problem which i am trying to resolve now for several weeks.

我有一个奇怪的问题，几个星期以来我一直在努力解决。


Our Network is organized like the following:

我们的网络组织如下：


WAN <-> PFSENSE-Firewall <-> 2x D-LINK DSG-28P <-> Clients

WAN<->PFSENSE防火墙<->2x D-LINK DSG-28P<->客户端


The manages switches are not managed at all but are configured with the default configuration. The PFSense acts as a DHCP-HOST. The Clients are all Windows 11 Pro (22H2).

manages交换机根本不受管理，而是使用默认配置进行配置。PFSense充当DHCP-HOST。客户端均为Windows 11 Pro（22H2）。


Now the weird thing: Every time we are searching for a Printer in Windows, the Client looses its Network connection. A restart of the client, Network.unplug-replug, restart of the PFsense, restart of the DHCP - this all does not solve the problem with the lost Network connection BUT a restart of the managed Switches does bring back the network connection.

现在奇怪的是：每次我们在Windows中搜索打印机时，客户端都会失去其网络连接。重新启动客户端，Network.unplug-plug，重新启动PFsense，重新启动DHCP-这一切都不能解决网络连接丢失的问题，但重新启动托管交换机确实会恢复网络连接。


If i perform a ipconfig /renew or /all on the designated client, it states that there is no DHCP-Host available ("No address is assigned to the end point of the network connection").

如果我在指定的客户端上执行ipconfig/renew或/all，则表示没有可用的DHCP主机（“没有为网络连接的端点分配地址”）。


Does anyone have any idea? I search hours and hours and hours but did not come to e real solution.

有人知道吗？我搜索了好几个小时，但没有找到真正的解决方案。


THanks

谢谢


UPDATE:
Seems that this is related to some weird chip incompatibility of the switches and the NIC-CHIP.
After setting the Ports from Auto-Speed to 1000M, it worked like charm :-)

更新：这似乎与交换机和NIC-chip的一些奇怪的芯片不兼容有关。在将端口从自动速度设置为1000M后，它就像魅力一样工作：-）


I will leave the question here in case someone has the same problem. Strange that i found the solution after i posted the question here...

我将把这个问题留在这里，以防有人有同样的问题。奇怪的是，我在这里发布问题后找到了解决方案。。。

I think I have a similar problem. My network is completely different: router mikrotik CRS328-24P-4S+ (os version 7.11.2) <-> wifi ac unifi UAP-AC-HD <-> PC with windows 10. Only two PCs have this problem (one connected by wifi and one by cable).
The problem is similar: when I start "search for printer" in standart windows dialog PC stop responding for pings and drop all RA connections. After a minute or so it actually connects back and the search is done, but I don't think it's a normal behevior.
We tried different WiFi adapters (on PC) but nothing changes.
