основная проблема все таки в том почему такой инет нестабильный при подключении через усб? может дело в линии?
При подключении через USB у многих модемы работают нестабильно.
Даже сами производители модемов не рекомендуют по возможности использовать USB, в последних моделях модемов уже нет USB портов.
Вот что пишут в документации по Dynalink RTA1025W (этот модем является прототипом ZXDSL 531

:
"Connection options:
1. Ethernet (Recommended - this option is Operating System independent.)
The modem router comes with single Ethernet port (RTA1320 & RTA1030W), or a built in 4-port switch (RTA1025W & RTA1046VW). If you require more ports, purchase a network switch to provide for more connections, or use wireless (see the next option). Only one Ethernet cable is provided. Extra cables and network switch can be purchased from your supplier.
2. Wireless LAN (Only for computers that support wireless LAN. This option is also Operating System independent.)
The router is also a wireless access point that supports IEEE 802.11g and 802.11b standards. To configure for wireless it is best to connect to a computer via Ethernet and then follow the Setup Procedure under Section 6 Setting up wireless. Model RTA1320 does not have this option.
3.
USB (Not recommended - this option is intended for a standalone Windows Vista/XP/2000/ME/98SE computer only)
Choose this option only if a computer does not have an Ethernet port and it is not feasible to add an Ethernet port or use wireless. You must then install a driver to operate the router. The USB driver and detailed installation instructions (in the User Manual) are located on the enclosed CD. Model RTA1046VW does not have this option."
