X3000 Spitz 4G Issues?

Hello all! I just got this device and I’m having some issues.

  1. I get “192.0.0.2” ip listed when I connect to 5G. On the latest firmware I get the following on repeat and cuts my internet every 10~s or so.

user.notice root: modem ip different, now regain ip …
Wed May 24 13:25:49 2023 daemon.notice netifd: Interface ‘modem_0001_4’ has lost the connection
Wed May 24 13:25:49 2023 daemon.warn dnsmasq[19495]: no servers found in /tmp/resolv.conf.d/resolv.conf.auto, will retry
Wed May 24 13:25:49 2023 daemon.notice netifd: Interface ‘modem_0001_4’ is now down
Wed May 24 13:25:49 2023 daemon.notice netifd: Interface ‘modem_0001_4’ is disabled
Wed May 24 13:25:49 2023 daemon.notice netifd: Interface ‘modem_0001_4’ is enabled
Wed May 24 13:25:49 2023 daemon.notice netifd: Interface ‘modem_0001_4’ is setting up now

My internet works perfect the whole time till it cuts out trying to regain IP. So I reverted to 4.3.0 without regain IP and it works perfectly 24/7. ( Anyway to fix please so I can use newer firmware in future? )

However here comes next issue.

  1. Horrible 4G upload speeds. Cudy P5 on 4G, same bands, same tower, same wireless bandwidth/channel, etc can upload 24/7 around 50-60Mbit on any computer in the house. On the Spitz, my computer can barely upload more then 2MB/S and my other computer can barely upload more than 700Kbit/s. If I change to 5G-SA both can upload around 70Mbit/s no problem. Both have excellent signal strength/quality to both routers. I have tried ethernet too.
    ( Similar cellular connection strength/quality on both devices since I’m using external waveform antenna )

I would think it was the tower but the router has something fishy going on since my other computer is getting capped to 700kbps while mine is at 2-3MB. I tried changing wireless cards between PC just in case too but same results. Ethernet gave the same results. The second I go back to cudy p5 with same bands/same wireless settings the upload is perfectly fine on 4G and both computers.

TDLR: 4G uploads tank on Spitz vs Cudy P5.

When you upgrade to the latest, turn off the “Keep Settings” to have a clean slate flashing! There is a bug if you keep your configs while flashing! The beta firmware I am running without issue is:
Version: 4.3.1
Date Compiled: 2023-05-12 13:35:27 (UTC+03:00)
SHA256: 55c03c8c1cf6b36397004cf16df263bf0a02c76034c53b6ac89fdb17e00fc5d6

Try it and let us know.

Thanks I’ll try it later tomorrow. What is this bug though?

I’m still getting constant

“user.notice root: modem ip different, now regain ip …”

which causes

“Wed May 24 13:25:49 2023 daemon.notice netifd: Interface ‘modem_0001_4’ is now down
Wed May 24 13:25:49 2023 daemon.notice netifd: Interface ‘modem_0001_4’ is disabled

Wed May 24 13:25:49 2023 daemon.notice netifd: Interface ‘modem_0001_4’ is setting up now”

when the IP listed is “192.0.0.2” from the cell tower. Can anyone help? It drops out every time it resets the interface

Edit: Would like to note this doesn’t happen on v8.3.0 but when I try v8.3.1 it happens. ( I try factory reset + clear all user settings too )

Getting exactly the same behavior on my own X3000. 4G speeds are terrible, but 5G is good, except that the same interface up/down happens every 10 seconds.

I am using Google Fi, and never activated the SIM that I received, I wonder if that might be the issue? What SIM/Network are you using?

Are you using a data sim or a voice sim? Either way I’m fairly certain that it needs to be activated. Probably easiest to do on a phone and then move it to the Spitz

Using T Mobile sim, and it’s activated

interesting - Google Fi is a T-Mobile sim at the end of the day, I wonder if there’s something weird with t-mobile? Waiting for my proper data sim (Fi sent me a voice/text/data sim by mistake that I can’t activate) and I’ll report.

I have updated my router to the latest beta (June 8th) and behavior is still the same, i.e. constant disconnect/reconnect in 5G, and super slow speeds in 4G…

I still get the same behavior too

Not sure about speeds, but I get the same disconnects every so often as stated above. Using Tmobile. 4.3.0 no issues, anything newer keeps disconnecting. Says modem down

daemon.notice netifd: Interface ‘modem_0001_4’ has lost the connection

daemon.notice netifd: Interface ‘modem_0001_4’ is now down
Thu Jun 8 21:22:36 2023 daemon.notice netifd: Interface ‘modem_0001_4’ is setting up now

ok, Google Fi told me they had sent me a bad type of SIM by mistake, and I received the correct Data SIM from them today, that changed everything - I guess a properly activated SIM does make a difference, unsurprisingly. With that new SIM the modem is super stable, including on 4.3.0.

Fi uses t-mobile in the background, but obviously a SIM with the right configuration does make a massive difference - again, not very surprising.
