Hi @SvenG , interesting topic, Do you see them at least with wireshark? [Determining a PLC’s IP Address using Wireshark - Share Info & Ideas / How-To & Wikis - B&R Community](https://community.br-automation.com/t/determining-a-plcs-ip-address-using-wireshark/495) Ciao Valerio ---

Hi Sven, which AS 4.12 are you using? I see we have an issue: ’ Browse for targets never finishes and no SNMP response is received’ fixed in the version 4.12.11.2 SP: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/1/1da8cb10eafac496013515d1a0fe728b9dd76e05.png) ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/9/9732fea37b3c63cf3fbf3252998be429721ce39f.png) Plus I’m sure you have activated SNMP in the cpu configuration: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/2/21c7e62cd7c7e28029af988d9b1142c948036aa6.png) Am I wrong?

Hi Sven, let’s focus on AS 4.12 first. I see you have 2 options: you can install the AS service pack or you have to downgrade your PVI: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/1/1c5bd3c33ed648ccf995d2e6c9db5eafbd5342ef.png) ==================== I understand this is frustrating, but when you report an AS issue, we do need to verify that your specific AS version is supported by your PC’s operating system: ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/d/d01116e4887475696b52d162345460e50cdbb71a.png) ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/4/4522583d9dbf7ce1d44acd0a783540a2e73c709f.png) Ciao Valerio ---

> but suddenly everything stopped I can’t prove that but may be a side effect of some windows upgrades… No other ideas for the moment Sven. ---

Hi, not sure if it helps, but: as far as I remember, the PVI4 snmp functions use the WinPCap driver for low level network packet inspection. If that driver is damaged or updated from another software to a incompatible version, I could imagine that snmp does not work anymore. So I would sugest to - check in the extracted PVI setup if you find a setup named winpcap - execute just this setup - if asked for “deinstall installed version”, confirm and deinstall it - restart and try again I’m not at PC right now, so I can’t give more conrete advice. But maybe it’s worth a try? ---
