Notes about the 426 file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The 426 file type is primarily associated with 'Speed Touch DSL Modem' by Compagnie Financière Alcatel. Please read the modem's manual for instructions on how to install a firmware update.
