@WooShell I have the same problem, just worse cuz Vodafone knows the CMTS is completely overloaded (>1500 subscribers instead if 512 maximum) since *at least 2019.
- Personally, I feel like I need to,escalate this to @BNetzA if not ask all the Neighbours if they too have this problem and would join in on a motion to nit only getbrefunded, but have Vidafinebfix their shit or pay for any costs of getting proper broadband connectivity equal to their advertisement.
In fact, if I were nit a #tennant but #owner I would've laid my own #FTTH with a pair if OS2 fibers for symmetric Ethernet 5+ years ago.
