How To Reboot Your Router Automatically In Ubuntu (Linux)

This tutorial should help you reboot your modem/router automatically . You can use this for many reasons . One of the reasons being BSNL provides free night usage between 2 and 8am . Therefore rebooting your modem once at 2am and then at 8am and scheduling your downloads can help you take advantage of free night unlimited. I've already made a similar tutorial for windows . CLICK HERE to view that tutorial . If your using linux (ubuntu ) then this tutorial is for you . SO here's how we do it :

INSTALL EXPECT - tool required for rebooting.

Step 1 : Go to the Terminal ( Applications->Accessories->Terminal) and type sudo apt-get install expect

SETUP REBOOT SCRIPT

Step 1 : Open Text Editor ( Applications->Accessories->Text Editor)
Step 2 : Now Copy - Paste the following code in the text editor and save it as router.exp . Save this file in your home folder . So your overall file link should be something like /home/prash/router.exp .where /home/prash is the link to your home folder

#!/usr/bin/expect -f



# router user name
set name "admin"

# router password
set pass "admin"

# router IP address
set routerip "192.168.1.1"

# Read command as arg to this script
set routercmd [lindex $argv 0]

# start telnet
spawn telnet $routerip

# send username & password
expect "Login:"
send -- "$name\n"
expect "Password:"
send -- "$pass\n"

# get out of ISP's Stupid menu program, go to shell
expect " -> "
send -- "reboot\n"

# execute command
expect "# "
send -- "$routercmdr"
# exit
send -- "^D"

Step 3 : Now Go to the Terminal (Applications->Accessories->Terminal) and type crontab -e
Step 4 : Then add the following 2 lines

15 2 * * * /home/prash/router.exp
45 7 * * * /home/prash/router.exp

NOTE : Replace /home/prash with your home directory link. The above 2 lines reboots your router at 2:15am and 7:45am respectively

Step 5 : Then Press CTRL+X to SAVE and then Press Y ( to confirm)

Step 6 : Thats it , your done , your modem/router should reboot

NOTE : This script works for ut300r2u . The script may need to be modified a bit for other modems.You could check THIS tutorial for scripts in windows and modify it to work in ubuntu. Just a little modification is required.For Huawei modems , your script would be :

#!/usr/bin/expect -f



# router user name
set name "admin"

# router password
set pass "admin"

# router IP address
set routerip "192.168.1.1"

# Read command as arg to this script
set routercmd [lindex $argv 0]

# start telnet
spawn telnet $routerip

# send username & password
expect "Login:"
send -- "$name\n"
expect "Password:"
send -- "$pass\n"

# get out of ISP's Stupid menu program, go to shell
expect " -> "
send -- "system restart\n"

# execute command
expect "# "
send -- "$routercmdr"
# exit
send -- "^D"
