Strange router problem with Cricket
Posted: Mon Aug 17, 2020 7:23 pm
I have now locked up (bricked) two different routers, both with the EC25AF modem in them. Both were based on OpenWrt but had customized it. I know how to do the Uboot procedure, holding in the reset button, plugging in the power, watching LED flashes or counting to 20 and connecting over the LAN port with a windows PC to 192.168.1.1. I tested that procedure and got the firmware upload screen. Then I plugged in a cricket data only SIM.
With both routers I was able to get a connection, I could surf the web, read my email, watch Netflix, run speedtests, etc. With both routers, after about an hour and 200-500 MB of data , I was suddenly disconnected from the internet and the LAN port would no longer respond. I powered off. I powered off, did a reset. I powered off and did a debrick/UBoot procedure. Nothing, no response on the LAN port. The lights look normal, but the LAN ports are not responding. I did make one mistake twice, I turned off the WIFI modems because I never intended to use the WIFI, so I can't try that and see if it too is unresponsive.
The first router was a KuWfi and after their tech support had no solutions, I sent it back to Amazon. The second router is a GL.Inet X750. I just emailed them a detailed description of what happened and the various ways I have tried to resurrect the router. But, I suspect that this one too is bricked. It's very strange. Two different hardware builds, but the same type modem.
I have never seen anything like this is my 50 years of electronics, I can still build a PC from parts and have recently built two Raspberry PI systems, so I am not a complete idiot with hardware and software.
