RS300 LAN Port Not Responding
I sometimes loose my internet connection from my LAN. DHCP seems to be working but the RS300 does not respond to ping and DNS does not respond, but it seems like routing is still happening cause I ca...
Q: What is connected to the LAN ports?
A: MS108EUP, which is connected to an RAX200 (AP Mode) and a bunch of MS308s and MS305s and a Pi4 traffic monitor (ntopng).
Q: Does this happen to any ethernet connected device behind the RS router?
A: not sure, I think I was able to access the RS300 via WiFi (RAX200 AP Mode connected via MS108EUP) because I rebooted it that way. The issue has not reproduced lately, we had an extended power outage recently. I have packet capture via the Pi4 so I should do a capture next time it occurs.
Q: What Firmware version is currently loaded?
A: V1.0.1.60
Q: What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
A: It's connected to a CM2050V via an ER707-M2 which is the primary firewall, internet access control, VLANs, guest network.
Does the LAN ports continue to exhibit this issue if you disconnnect all Switches from behind the RS router and connect the RS router directly to the CM modem to check this. Would like to know if this configuration continues to see this issue or not.
I think this could be due to RTL8156BG controller issues I was having. I turned off some of the offload settings and it seems stable now.
So a RT ethernet adatper?
Ya, UGREEN 2.5 Gb USB dongle, I tried a number of them and they all seem to suffer from disconnects, overheating? I read somewhere on reddit turning off some features like offload helped, but turning off checksum offload is really slow on this tiny thinkcentre, so I turned checksum offload back on and it seems happy. I did have the Intel M.2 2.5Gb which I think was working well, but I put a P400 NVidia card in the tiny and the back panel bracket doesn't currently have room for the RJ45. When I upgraded my network to 2.5G I got a ThinkStation P3 Ultra which has onboard 2.5G Intel I think? The P3 can do 2.5G across all the switches and routers to the speedtest servers until you install Bitdefender (sad).
