Don't worry, I wont be downgrading the firmware. I read about the critical update some months ago so decided to upgrade back then. Would be interesting to know if it is the latest firmware causing the drop outs though. Oh, and the setting is configured to be 'Always on' so I'm guessing there is a problem with the Draytek or something up with the firmware.
Since plugging in the BT HG612 modem and then running that into the Draytek via the ethernet, internet has stayed on consistently and not dropped once. We'll probably purchase a new Draytek 2862, mainly as I'm familiar with these plus I can (apparently) restore the backup configuration from the 2860 to the 2862 which will save me a lot of time.
Thanks for all advice offered
The company I work for is spread across six geographical locations each using Draytek routers with most having a dual broadband service from different ISPs which may be any combination of TalkTalk, Zen, BT, Cloudscape and EE. You would expect the system up time to match the WAN1 and WAN2 up time, but at no site do we have that utopia situation and generally if you have dropouts, one broadband connection is rock solid with the other being less so.
I can only speculate the reasons for it and concluded it could be a local congestion problem and/or the backbone is not adequate. Services have been swapped over from modem to WAN2 on the Draytel unit with the less satisfactory service remaining the same. So the doggy service is given the elbow at contract end for another ISP and generally that resolves the issue.
Draytek firmware used:
Firmware Version: 18.104.22.168_BT DSL Version: 576D17_A/B/C HW: A
Currently most of the routers are Vigor2860Vac with the VoIP functionality specified to provide an ‘office’ phone for the end user. Enables me to call them for free! Voipfone is the provider
