Frequent dropped connections with provider


#1

Hello, I have a Max BR1 running the v7.0.1 firmware. I recently needed to change ISP due to bandwidth issues. My new provider (Tigo, in Senegal, West Africa) is working wonderfully as far as speed goes, but I’m getting lots of disconnections from the ISP. It’s not a signal strength problem (RSSI is -79dBm / 5 bars). I did not have this problem with my old provider (Orange Senegal). Thanks for any help you can offer me.

This could be a health-check issue and their DNS servers could be a little flaky. Try using a different target.

Thanks, Tim. I’m currently set to SmartCheck as the method, which I understand is preferred for 3g connections. Is this not what I want to do? There is no way to set a different DNS server with SmartCheck, correct? Thanks for your continued help.

SmartCheck is good to use on cellular because it will not keep doing the health check as long as there is active traffic passing through. If it goes idle for a while then it will use the DNS servers that are defined under the WAN Connection Settings further up the page.

Tim, thanks for that info. Didn’t know SmartCheck used the DNS servers listed in the “WAN Connection Settings” area (assuming those are the ones you’re talking about). If so, I’m using the DNS servers for opendns.org, so they shouldn’t be flaky. Any other ideas?

Thanks!

Does your Event Log show these disconnections?

Yes. As example from today:

This shows that it is not a healthcheck issue because they would be logged. Looks to me like the carrier is resetting your connection because you keep getting a different IP address. We already know it is not the router because it was fine with the other carrier.

BTW, DDNS is not going to work because you are getting a private IP address - not public.

Thanks so much, Tim, for the sanity check. So in regards to the dropped connections, there’s no chance this is a configuration / compatibility issue between the Peplink and this new ISP?

And I hadn’t even noticed that they are serving private IPs. Thanks for pointing that out.

I would check with the carrier on this, maybe they have a very short DHCP lease time.
