Thread: Renew Ip for UT300R2

Is there any command for renewing the IP address while using UT 300R2 Modem ?

I tried the BusyBox method, but it only has option to reboot the modem.


Is there a way to just renew/refresh IP in PPPoE mode ?

strange , nobody's got a solution ? :huh:

Are you looking for an option like this ?
seen in my Wifi router WGR614 V6.

Also available in SMC barricade 7400.

Attachment 5552

Usually not available in any ADSL modem.
Have not come across this option so far.
( checked Beetel 110Bx1 )

Use the autoreboot method posted here:

Automatic rebooting of router at 2 AM and 8 AM

Run it as many times. Most of the times, the dynamic IP will be renewed and different. In rare cases, you may get the same IP.

No.

I'm looking for method to renew IP using command line/batch file method similar to how it is done in bridge mode.

Already using the method of rebooting the modem, i want to know if there is any command to just renew the IP instead of rebooting the modem.

You can't renew the IP from BSNL like 59 or 117 untile you reconnect to the ISP or it will automatically renew the IP if you switch on the router 24hours. every 24 hours the IP from BSNL side renewed.

I dont' have this Modem so i can't tell you the exact syntax but for my Router "D-Link GLB-802C" i use the following command to renew WAN IP without rebooting the Router

Code:

modify ppp intf ifname ppp-0 stop
modify ppp intf ifname ppp-0 start

Telnet to your router and look for the similar commands.

HTH

Code:

modify ppp intf ifname ppp-0 stop
modify ppp intf ifname ppp-0 start

Karamjeet this is really good
No need to restart the Router.

Good method but this is very much same as rebooting the router.

Nope, this doesn't restarts the router it only reconnects the PPP interface and hardly takes 2-3 seconds as compared to more than one minute in case of Router reboot.

thanks.

i'm not able to lookup for a equivalent command any help ?

these are the supported commands of my modem/router

BusyBox v0.61.pre (2004.10.22-12:27+0000) multi-call binary

Usage: busybox [function] [arguments]...
or: [function] [arguments]...

Currently defined functions:
[, ash, busybox, cat, chgrp, chmod, chown, cp, date, dd, df, echo,
false, free, grep, hostname, id, ifconfig, init, insmod, kill,
ln, login, ls, lsmod, mkdir, modprobe, mount, mv, passwd, ping,
ps, pwd, reboot, rm, rmmod, route, sh, sleep, sync, tar, test,
tftp, touch, true, tty, umount, wget, whoami, yes

Try this

Code:

ifconfig ppp-0 down
ifconfig ppp-0 up

change ppp-0 with appropriate interface name.

if above commands fail try

Code:

ifconfig --help

tried "ifconfig ppp0 down", the connection doesn't work after that, even if i use "ifconfig ppp0 up".

there is no other way to make it work than to reboot the modem

it means "ifconfig ppp0 down" successfully disconnected the PPP interface but "ifconfig ppp0 up" was unable to connect it again.

please post output of "ifconfig --help" command ?

# ifconfig --help
BusyBox v0.61.pre (2004.10.22-12:27+0000) multi-call binary

Usage: ifconfig [-a] <interface> [<address>]

one thing i noted was, even after the "down" command, the external Ip hadn't changed. I noted this using the "ifconfig ppp0" command.

or is it supposed to change only if "up" command is executed properly ?

Actually what is the problem is using the "reboot" command?

Whether you use ifconfig or any other command, you still have to telnet to the router.

Say you’ve got a Ubuntu system with a DHCP address, and you want to release that address and obtain a new one. Releasing a DHCP address in Ubuntu is quite simple. Go to a Terminal window and type this command:

sudo dhclient -r

(Note that you must use dhclient either as root or with the sudo command for it to work.)

This will release your current IP address. To obtain a new one, use the dhclient without any arguments:

sudo dhclient

Assuming that dhclient can reach a DHCP server, your system will receive a new IP address in short order.

like "Karamjeet" explained renewing Ip takes only 2-3 seconds compared to rebooting which takes a longer time.

thank you very much, but i'm looking for solution in windows.

For Windows XP Pro, try this command in Command prompt:

Code:

ipconfig /renew

@madz
not working bro

OK. I researched a bit and got the solution.

The important thing to note is that the Network adapter should be configured as DHCP enabled. If you are using static IP address, this command won't work. Please configure the TCP/IP properties of the Network adapter as Obtain an IP address automatically.

First, in Command prompt type:

Code:

ipconfig /release

Then, type:

Code:

ipconfig /renew

For all the commands to use with ipconfig refer:

I have a problem with the static IP part

because the router is assigned a static IP as it works like a gateway, so I guess this won't work either.

when i tried the command it made the IP as 0.0.0.0 and after renewing, it was assigned the same default IP.

Anyways thanks for all the help

wont that command just renew your LAN ip and not your WAN Ip
