I have decided to try, again, to make my home cellular network work better on my Librem 5. (I have more free-time during this snowy holiday season). In my high-tech web research, I am exposed to suggestions very similar to this: “download the “Network Signal Info” or “Open Signal” app on your Android or IOS device and test from there.” The problem? I own a Librem 5 with a Linux operating system.
I bought a cheap network signal enhancer and it does, kind of, work. I have run cabling, etc. I have a “booster”. However, I am having difficulty doing any cogent testing of signal strength, etc, based on where I put the antenna. I am relagated to switching my Mint mobile SIM to my old Android device and testing from there. That is silly.
Any thoughts on how to test cellular signal strength so that I can troubleshoot this issue using only my linuxy Librem 5?
Much appreciated for any help anybody might provide.
This is super cool. Thank you. 2. I don’t know if it will resolve my situation but I am sure it will not hurt my situation. I think the “walking around the house and percentage of strength indication” will certainly not hurt.
I will report back once testing has been commenced. Thank you!
Interestingly, my phone tells me that it registers a LTE, 4G signal at around 40-60%. However, my Mint card (T-Mobile) does not show up as the “Network Type”. Am I testing that signal or can I test only T-Mobile? Stated differently, can I differentiate between what signal or network I am picking up? I have no idea what this phanton LTE 4G signal apparently is. It doesn’t register for me. I suppose it could be Verizon. I do not know.
I, too, have service from an MVNO that uses T-mobile’s network, and the command always shows T-mobile as the LTE signal for me. Could yours be showing something related to your network signal enhancer?
Otherwise, the displayed MCC+MNC code might help you identify the source of your signal:
(P.S. I know for a fact that there are other strong LTE signals in my area besides T-mobile.)
Can you elaborate on what this is? e.g. make/model
If you are interested in the cellular network signal strength then the magic AT command is AT+CSQ
The response will be +CSQ:n,m
where n is the number you are interested in.
n will either be 99 (unknown) or it will be a number in the range 0 to 31 where 0 is weakest and 31 is strongest. (Can be converted arithmetically to a dBm value but that conversion may hinder rather than help here so details omitted.)
I am still playing with my poor at-home cellular coverage. I have some home coverage now but another odd issue persists: my cellular modem keeps picking up a different signal and (I believe), because it is stronger than my Mint/T-Mobile Signal, it switches to the stronger signal, consistantly. Very annoying.
Is there a way to point the modem at only a particular “signal” - e.g.: the signal I want it to recognize and use?
Are you still able to make a call or does the phone deregister? I’m asking because I’m having this issue where in some places in my area it’s not registering but I get sometimes full bars. It’s very odd, and the reason I’m sending my phone back again to Purism.
T-mobile/Mint/etc. should be something like 310 and 260 (or 240, etc.).
I don’t know anything about extenders, but isn’t it acting sort of like a bridge or access point, except instead of WiFi, it’s the mobile network…? When you’re connecting to the extender, it might show something other than Mint/T-mobile.
Could your extender be a clandestine surveillance device produced and controlled by a foreign nation?
