Thanks Brash and PhilipDAth - I'll check speed/duplex on WAN port and on ISP device when I get a chance as both of you suggested that - Brash, the devices behind MS are also seeing high latency and packet loss too, it's not just the graphs,  - thanks for the advice - Hans ... View more

Hi Brash thanks for the reply. No, absolutely no alerts on Dashboard! This configuration had been working without problem for 18 months, until suddenly WAN1 went down and Virgin replaced their modem. New modem tests fine & I believe it is ok. Would Meraki upstream connectivity test affect MULTIPLE MX100's? - we're getting the same loss on both primary and secondary MX100 (tested individually) - I could try a factory reset on the modem. Didn't think of that as it's a brand new one and tested fine otherwise, but I could try that - thanks,  ... View more

MX100 WAN1 packet loss

Newbie not too experienced, so any help really appreciated and sorry for long description   We have 2 x Meraki MX100 (primary and backup) both connecting to WAN1 (Virgin / Hitron modem) and WAN2 (EIR) with load sharing enabled A few weeks ago WAN1 went down and Virgin replaced the Hitron router/modem Ever since, we have been experiencing high latency and 50-75% packet loss on WAN 1 (VIRGIN )   if a laptop is plugged directly into Virgin/Hitron, we get perfect results, ping times of 1-2ms, no data loss, internet speeds of 250Mb Virgin say their line and Hitron modem test fine and it has to be a Meraki problem or issue   We get the same results whether using the primary or secondary Meraki MX-100, so unlikely to be a port failure? We have changed out WAN and LAN cables and consistently get packet loss on WAN1 Firmware was updated to latest stable version   Meraki tech support did packet capture on Wan 1 and Wan 2. The output shows that MX 100 is sending TCP SYN packets but not receiving anything back.   Has anyone experienced anything similar with Virgin Ireland (Hitron) recently or any suggestions as to what we could try? Any advice or troubleshooting/testing suggestions really appreciated - many thanks ... View more
