Ongoing MOFI 4500 Connection Issues
Posted: Sat Nov 14, 2020 3:24 pm
Hey gang - I've got quite story here, would appreciate any suggestions...
I've been using a MOFI4500 (thru ubifi) for ~2 years now and it's been working great - I have it paired with a Wilson Yagi directional antenna and get reasonable speeds 5MB UP and 20-50MB (locked to band 12) down depending on the day/time of day. I'm on the latest MOFI firmware from earlier this week, 4.3.2 I believe and am usually pretty current, I was on 4.2.x when the issues started.
About a month ago, I started getting connection drops every hour or two, and while it was surmountable, it takes MS Teams about 2 minutes to recover from the connection loss, so being in meetings it's painful when that happens. So, I started to experiment, bought a used Netgear LB1120 and threw the Ubifi SIM in that (and paired it with a CISCO RV345 I have for routing/DHCP) and I was getting drops every hour on the hour it seemed. The Netgear would be up and show a valid connection, but if I rebooted the Netgear, it'd be fine for another hour or so.
It seemed the problem was signal related, so I went back to the MOFI, now in bridge mode, but couldn't get it to play nice with the RV345 (the RV345 would see the MOFI on the WAN1, but I couldn't get any traffic to flow). So I threw my old WNDR3700 Netgear in the mix for router/DHCP and it works OK (MOFI still in bridge mode), but I have the same variable connection drop every hour or two (just like in the beginning with only the MOFI).
When it drops, I get about 20 seconds of no DNS (Chrome will usually show a dns issue and no connection message), it'll also take a long time for the MOFI GUI to render the login screen, probably 10 seconds on it's own instead of the usual instantaneous speed. I was thinking it was an issue with the cell signal since the Netgear LB1120 was having the same cyclical drops, but I'm thinking that was a coincidence since the MOFI seems to be hung when I try to hit it during one of the outages.
I exported the logs from the MOFI, but they come out encrypted (to my surprise) and I was unwilling to invest the time to figure out how to decrypt them.
Any thoughts or ideas on where to look next? I can simplify and go back to just the MOFI acting as router/DHCP if that simplifies troubleshooting suggestions...
