I Bought One Bsnl Wll Of Huawei ,model Ec325.am Having Rhel5 Server Installed And Fedora 8.but Unablto Configure It To Access The Net.plz Help Me How Will I Configure It...

hi! it is as usual in dialup connection
use "wvdialconf /etc/wvdial.conf" command and edit the username and password which u know
otherwise use below contents in wvdial.conf file
[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 460800
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem
Phone = #777
Username = <username>
Password = <password>

u sould edit your username and password

it will be connected but ur browser wont work
first uncheck work offline
still it wont work
edit /etc/resolve.conf with the following

nameserver 218.248.240.23
nameserver 218.248.240.135
note above two lines, it is the address of primary and secondary DNS IP

you can also configure your modem for pppoe mode in this case you dont need any dialer.
configure your nic for dhcp server ie. your modem or static as per your need.
use you modem's ip as defaultgateway ie. 192.168.1.1 mask as 255.255.255.0 (/24) and 208.67.220.220 208.67.222.222 as dns sever.
