No ip on comtrend ar-5381u, will not connect to internet

DO NOT INSERT A PAPER CLIP TO RESET THE MODEM! unless you know how to reprogram the router, this includes having complete knowledge of ALL the settings required by the ISP AND having your username and modem password (modem authentication passwords are not usually provided to the customer) Doing a "hard boot" will only return your modem to factory settings

I forgot my password and cant think of it how can i get a new one or reset it with out losing every thing on my computer i need the password so i can get the internet on my wii

the comtrend router password has nothing to do with the PC you can reset the router and then use the default username and password - ASSUMING you already tried the username and password and it did not let you log into the router setup screen
theres a few routers starting CT507 (1 , 1E etc ) see the download page here for a user manual

Belkin F5D8236-4 won't connect to the internet.

this issue mostly comes with dsl connections..

check whether the dsl modem is in bridge mode or pppoe method

if it is in bridge mode ask the isp vendor to change the modem into bridge mode which prompts you for username & password

try this it resolves the issue..

Bridge mode

Reset your modem.
There is a reset button on the back.
Push it in and hold it down for thirty seconds with the modem on.
Log into the modem at (admin/password=username/password)
You will need to change the modems administration username/password, doesn't matter what to since we'll make it unreachable soon enough.
On the connection overview page goto configuration.
Go to DHCP configuration and switch the DHCP server off.
Then goto configuration and click on VC configuration.
All but the first VC should be disabled.
Click on the edit or configure button next to the first and enabled VC.
Switch from either DHCP or PPPoE to Bridge.
At the bottom of the screen click on set VC.
Your modem is now in 'full bridge' mode and will need to be reset again to get it out.

Comtrend ADSL2+ Router CT-5621T

there's quite serious security problem with this routers (not sure if it applies to exactly this type) 

if your password if not the default you should try other account:
(username / password)
admin / admin
support / support 
user / user 

if you are logged in as a "user" you can't change anything but you can access change password page e.g.

then open source code of this page and inside javascript code you will find your password in plain text
<!-- hide
pwdAdmin = 'admin';
pwdSupport = 'support';
pwdUser = 'user';

Router login


If your Comtrend CT-5621 came with the package from your ISP then it is possible that the username and password has been changed by your provider and you would have to get in touch with them.

In some instances the username is "root" and the password is "root".
Some known passwords from ISPs are:
Canadian Broadband/Aliant - RM60008
NetComm - NetC0mmV3oo

Some ISPs disabled/blocked the web based configuration interface and the initial way to communicate with it is a telnet session to the router.

Would you know if your default IP address of

Good luck and kind regards.
