  • We have that available, I just use mobile data because I disagree with their ToS.
    The ToS is so restrictive that you basically immediately break it after connecting a device. I was told that, of course, they don’t really care.
    Except - there is a point stating the provider has the right to access your computer if there is a suspicion of ToS violation. Considering the network here is a student-run organization, that could easily be exploited if you piss off someone.
    Maybe I am just paranoid, but no thanks.

    Otherwise, from talking with them, most dorms have 1Gbit, some have 2.5Gbit, and all share a 40Gbit link which could apparently do 100Gbit (I think), but it’s capped due to licensing.
    They leverage national academic network.
    Oh, and they also got a class B subnet back when everyone was sure there’s just way too many IPv4s, so NAT isn’t being used here.










  • My last 3 phones are just kind of pain software wise.
    Moto G5s Plus - the Android 8 update (latest official) made it a slow horrible mess with frequent crashes and high battery drain. PixelExperience 11 fixed that.
    Poco X3 Pro - told not to update to MIUI 13 due to instability. Many bugs I had to learn to work around. Left and right microphones reversed in software. Extreme power saving that doesn’t even spare alarms.
    Ulefone Armor 24 - UI often crashes (Quickstep) including navigation. In some cases Android version updates don’t show up. The legend has it they sometimes provide updates after you e-mail them, stored on the Google Drive. Those updates do a factory reset, because of course they do. Alarm also has a chance of being killed, but lower than with MIUI. Charging with fast charger kills USB communication until reboot.

    I don’t do updates anymore. Check the experiences online, and it’s all just new bugs, often pretty serious ones. So, if it somewhat works, and it isn’t absolutely clear that the next update would certainly fix something important, just keep it as-is.

    TWRP could at least give me some peace of mind. I could just back up everything.






  • I achieve the same by disabling VoLTE and VoWiFi and setting the phone to LTE only in *#*#4636#*#*.

    I love these service menus. *#*#3646633#*#* has so much stuff to permanently screw up on some MediaTeks. But also some useful ones like selection of frequency bands, or even specific frequency and cell id.
    But yeah, some settings can persist factory reset, and some may even be illegal like Tx tests (verified that it does transmit garbage on selected frequency with SDR) or IMEI change. Not all settings are on all devices, and they may even be partially broken.

    But yeah, these settings are don’t touch it for the most part (some are just huge lists of undocumented variables). Some don’t even seem to be resettable from the menu, I mean menus where you select one option, but by default they are unset. And the band mode selection on Moto G54 5G was… interesting. Rather than a nice selection menu, you can type in a number and select to add or remove it from a vector variable for 4G and 5G. Of course, nowhere does it list valid options or give a reset button.

    And lastly a thing that serves me as a warning for future, when I was playing around with a leaked service program for some Realtek Ethernet adapter, I found out what eFuse memory is. There is no going back.
