Zdar chlapi mám stejný problém, ale nemůžu najít řešení podle předchozího návodu - mám tuto hlášku :
ROUTER NEEDS A NEW LICENSE
----------------------------
This RouterOS version is designed to work only with new format RouterOS
keys. These keys can be recognized by the longer SoftID, which is 8
characters long, instead of previous 7.
The upgrade to new format key is free of charge, and can be done
automatically right now in Winbox.
Please click on "Update license Key" button in the System License menu to
get the new key (your Windows computer needs to be connected to Internet).
If you do not update the key, this RouterOS installation will expire in
69h17m, and will require a complete reinstall.
Please press "Enter" to continue!
Na stránkách mi to napsalo, že mám licenci uloženu v adresáři i4wifi-nase firma, ale adresář nikde. Jedná se o upgrade 3.22 na 4.11. Down na 3.28 už mi nejde. Díky za každou radu.
