Comtrend router hacked

Hi guys, I have a CT 5361 T router and my username and password are hacked, this because i can't log in my router. I have contacted my help desk in my country and they told me to reset the router, but this wasn't of any use. What is/are the best steps which i can undertake or other alternatives which can be helpful in order to increase my router security. Thanks.

SOURCE: i need to password secure my belkin wireless router

This is not a difficult task, but if it is done incorrectly, your router will need to be reset. So, let's go ahead and get a long, thin pin, or sewing needle,or something that will reach into the recessed reset button hole, because we may need it a few times.
I too have a belkin wireless router, so I know a little about them. However, I dont know your exact model or firmware/software programming, so a true "step by step" is not possible from me. Contact Belkin for operator assistance. Here are some General things you will need to do.
1. Reset the router. Go ahead and do that now. that way, we have a clean slate. Press the reset button and allow the router to restart.
2. Make sure the Modem is connected to the INTERNET port on the router. You should see 5 ports on the router, 1 2 3 4 are ONLY FOR COMPUTERS. if it has a number do not put anything on it unless its a computer, or xbox or playstation game console. The MODEM, the DSL, or w/e will NEVER go to ports 1 2 3 or 4. Now, make sure that your MAIN computer is HARD WIRED to PORT 1 on the router. You DO NOT EVER make wireless router adjustments over a wireless connection. You must hard wire to the router.
3. LOG IN to the router. The router has a built in website that allows you to operate it. on a belkin router, that website is located at the Default Gateway address. (ok, you probably dont know what that means, but thats ok, we can still do this). MOST belkins have a default gateway address of 192.168.2.1. So, you will open your internet explorer and go to the ADDRESS BAR. There, you will type http://192.168.2.1 and press GO. You SHOULD see a page that says Belkin.
4. BY DEFAULT there is no username or password. so if you are asked to login, leave them blank and hit submit.
5. this is where it can get hairy, but, its nothing the reset button cannot fix. You will be looking for a few things First thing to do is click login, of course, so you can log in. remember, its default, so its blank.
6. Now that youre logged in, look for WIRELESS and click there. If you are using wireless machines, make sure wireless is ENABLED. It should be, by default, but, lets take a look and make sure, just to be safe.
7. Next, were gonna set the SSID to your last name, (or your dogs name or your nickname or favorite place). The SSID is default to Belkin, but if 10 ppl around you ALL have belkin routers, you'd have no way of knowing which one is yours, So, the SSID boradcasts a unique name to identify YOUR network. Changing the word Belkin to "Scoobydoo" would mean that you would be the Scoobydoo network, and anytime anyone is in range of your router, they would see "scoobydoo" as a site. You also want to ENABLE Essid broadcast, and unless you have an older wireless B card, set to Wireless G only. (g is more secure). Everything else, leave at the current setting.
8. Now we are going to SECURE your wireless so that when people see "scoobydoo" they wont be able to JOIN it, unless they have your KEY. Click Security. We are going to create a key. With Wireless G you can use a 26 character key, which is a set of HEXIDECIMAL characters. HEX is 0-9 and A-F. No letter higher than F will occur in Hex. So, click WEP (wpa is usually more secure, but I prefer WEP). Choose WEP and Choose 128 bit encryption. Next, use a passphrase, (this will generate a key for you). Say you put "shaggy" as the passphrase. Based on that word, a 26 character key would be generated. Now, This is important, WRITE THAT KEY DOWN EXACTLY AS ITS SHOWN. Without that key, no one can access your router on wireless. Also, dont forget to press "Apply Changes". Once you apply those changes, all your wireless connections will be lost. You will now have to go to each wireless computer, and apply the key to each one so they can access the router.

SOURCE: Comtrend CT-5367 changed firmware

your modem has a key gen serial number that is used by your isp to allow you interent access and if you change isp providers they usually will make you buy one of their modems to gain access seldom have i seen where they will give you access to thier service with a unregristered modem the serial number is the only way they can go to turn service on and off for non payment

SOURCE: 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.

http://192.168.1.1/password.html

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';

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

Every time my power goes out I have to completely re-setup my whole network. The comtrend ct-5072t modem does not seem to want to communicate with my linksys wrt54gl router. changed the ip on the router...


With changing the IP and all that business it may have messed it up a little bit.
This may not be the most sophisticated way of fixing it, but this is what I personally would recommend. THIS WILL ERASE YOUR ROUTER CONFIGURATION, but at this point that should be a good thing.
On both the Comtrend modem and the Linksys router, there should be a "reset" button. Grab a pencil or something long and skinny to press the reset button. Press on the reset button for 5 seconds on both the Modem and the Router.
Then make sure all of your wires are plugged in correctly. Go into your Router's web configuration by opening up Internet Explorer, Firefox, Chrome, etc. and typing "192.168.1.1". The username should be "Admin" and the password should be "password".
After you log in, change the Wireless settings and setup a password for your network and a name for your network.
Unless your Router is truly is faulty, then it may still reset on a power outage, but it should retain all of these settings.
Hope this helps.
Thanks for using FixYa.

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 http://www.comtrend.com/support.htm

Router login


Hi,

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 10.0.0.1?

Good luck and kind regards.
