We have a NBN connection that connects to a Telstra supplied netgear DEVG2020 router
There are 2 ethernets connection on this router
1. Telstra supplied Linksys Voip 8 port IP telephony gateway
2. Netgear 24 port gigabit Prosafe switch (This is new as we wanted to keep all products from the same vendor to stop any issues)
We also have a Telstra Netgear 4G USB modem configured as a backup link if we lose NBN connectivity on the DEVG2020
We have a Hybrex G1E Hybrid pabx connected to the Linksys voip gateway to support our phones. We have 3 phone lines and a fax line that is connected to the voip gateway.
The issue we have is that the router randomly resets itself on a daily basis. Minimum once and a maximum 3 times during 9:00am to 5:00pm
This has been occurring over the past 12 months and we have had 3 DEVG2020 routers changed including power adapters with no change. We have changed UPS and connected to direct power and still no joy.
I have noticed that when we lose connectivity on the LAN, the LAN light goes off first on the router and after a 30 - 45 secs the router will restart itself.
Total outage is between 3-4 minutes. All system are cloud based and when this happen all 8 staff cannot work and it is a major issue with staff.
Any help or thoughts on what we can try will be appreciated.
