Hi, Currently I have Unlimited 100/40 NBN service. Up until about 3 months ago the service was working with no issues. However as of the last 3 months I noticed drop outs when transferring files from my Acronis Backup cloud service and other large downloads that would take longer than an hour. Also I noticed drop outs whilst using works VPN client.
I did some investigations and got usual bad response from Level 1 Optus chat team which I expected. I spoke to someone on the phone around a month ago too where they didn't give me the best answer either but at least acknowledged there were issues. They advised they were going to try and get me a static IP assigned, but I clearly can see this hasn't been done as I will elaborate below. I setup some basic monitoring during the day today again but have done it several times in the past with same results. This is what I see. Optus please understand I am a Network specialist at my work place, whilst not an engineer, I have more than basic network knowledge so don't waste my time with stupid questions or responses that your chat and phone support techs have literally said to me.
"Your IP address shouldn't change because we assign your IP through DHCP" - Really do you even know what the heck you are talking about?
"Your Meraki MX is faulty and is assigning the IP incorrectly" Umm what? Again stupid stupid stupid.
"Your Meraki MX is faulty please use Optus router" - Fair question but my MX is not faulty and this is an IP assignment issue not a connectivity issue, my MX has no control over the WAN IP that it is assigned.
This is the list of troubleshooting steps I have performed to identify the issues.
1. Obtain my WAN IP from my Meraki MX64
2. Setup ping to this WAN IP
3. Meraki MX's provide a DNS for MX's which auto update with the WAN IP as shown in the dashboard, I then setup a ping to this DNS as well which when working confirms the correct IP
4. Within an hour, usually within 40 - 50mins I get drops, this then switches to a new IP address.
5. This will generally repeat and then will flip back to the previous IP that it was. It appears that there are two IP's that my MX keeps getting given by Optus. I can provide these IP's but I would rather not do this in a public forum for security reasons obviously.
6. Meraki MX logs show primary uplink status change is ocurring about 4 - 5 times in an hour, but the IP change does not consistently happen on each drop.
I have many screenshots and time stamps when these issues occurr please let me know how I can send these to you if necessary.
Hey @DanBostock, thanks for reaching out, I'm so sorry for the issues getting assistance here. We'll need to see your account to check on your static IP settings. Please feel free to send me a private message with your account number, full name and DOB so we can check it out and get back to you asap.
I was just wondering if optus has managed to fix your issue. To me it suggests a problem on their end where you Static IP just changes suddently.
On another note, I was looking at using a Meraki mx64 with my own Optus FTTB and was wondeing if you would be happy to share any info on how you managed to do it. I tried it myself but had no luck at the time.
I am having the same issue - with a Meraki MX64.
DHCP address is changing after a period of about 3 dropped pings, and flip flops every 10 minutes or so between the two DHCP addresses. When I swap out the Meraki MX64, the Optus modem is stable.
Weird. Meraki case said to change cable. Said Outage logged on dashboard says upstream gateway not responding to arp requests.
Were you able to find a solution or a way forward?
