Reset There are two ways to reset the Router's

factory defaults. Either press and hold the Reset

Button for approximately five seconds, or restore

There should be a small hole with a red circle around it on the back of the router next to the power plug hole. Use a pin or straighten paper clip to push the tiny button.

try changing the 2.4ghz wireless channel to 1 or 11

Hi,
Welcome to FixYa!

For you to be able to do that, you will need to set the SMC router to bridge mode, you will not be able to do that by yourself because only tech from your ISP have the capability of doing that since they have this tool that can operate on the router setting it to bridgemode. Basically, you will need to call your ISP to set the router to bridgemode and from there, you will be able to configure the linksys router.
Hope this information will help.

Your response is very much appreciated. Thank you for using FixYa!

If this is a new wireless router, make sure that the ethernet cable going from the modem to the router is connected to the right port on the router. it will be labeled either internet or WAN. Then, make sure that you unplug the modem for about 30 seconds to clear out it's memory, then plug it back in. If the router is not new, then try holding the reset button on the back or bottom of the router in while you unplug and plug it back in. This will reset the router back to the factory default and you should be able to connect.

Try reflashing the router, the firmware is available here: http://homedownloads.cisco.com/downloads/firmware/WRT400N_1.0.02_Build_11.bin
If that does not correct the issue, try physically moving the router away from any sources of heat, as that can also cause the issue.

NO.But give a try to Password RevealerPassword Revealer (only 65 kB - Windows 95/98/Me/NT) is a utility that can show you most passwords that are typed in a password edit box (those that hide ...

The WEP encryption key (network key) is in your wireless router, without this key the wireless router won't allow the computer or laptop to connect to this wireless router.
I recommend you use WPA or WPA2 encryption, it is much stronger than WEP.
The WEP, WPA, WPA2 encryption key is in your router's wireless settings. Log into your router and got to the wireless settings, you will need to get the SSID and the encryption key. Then go to your computer or laptop's wireless card and configure it with the router's SSID and encryption key, so it will then connect to the wireless router and the Internet.

An important feature of SES (the 15 character password) is wireless security...if you are using wireless adapter and if you are not aware of the wireless settings of the router, at that point on the wireless adapter software you may find SES button... once you press that button, wireless security on the router would change to "WPA" and adapter will automatically pick up the "WPA" security from the router...
You cannot use SES and WPA2 at the same time. SES will only activate once you push the SES button on the adapter or sometime in the router assuming you dont know the WPA2 security, but if you do know the WPA2 no need to use SES (15 character password).

Connect your router to computer with ethernet cable then you can access it with following default link. http://192.168.1.1 or http://192.168.0.1 or http://192.168.15.1 or http://192.168.2.1 If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it. Then it ask for user name and password. Type user as "admin" and password as "admin" or "password" or blank. Then you can see configuration page of router. If you are still not able to access router with above ip then you need to RESET it for that press RESET button for 10 seconds it is in back side of router then all settings defaults..Then you can access it with above method. . Then click on wireless->wireless security->WEP security there is code password note down it or enter new password then save setting s and restart router. then you can connect wireless with new password. Let me know if you need further assistance. Thanks for using FixYa.

Hi Friend,

2.in the black window type ipconfig and hit enter.
3. Note down the default gateway and close this window.
5.Open the web browser and type the default gateway and hitenter.
6.if you have not changed the defalut password of the router then type admin as the password and leave the username blank.
7.In the router setup page click Wireless and then click Wireless Security. Please note down the WPA shared key if the security mode is set to WPA.

I hope this will resolve the issue.

You need the Ethernet Cable in your Router to be able to connect to the Internet.That is the only way your going to be able to have Internet.It will not work without the Ethernet cable.

First turn on the router then press RESET/WPS button for 10 seconds it is in back side of router then all settings defaults.
Connect your router to computer with ethernet cable then you can access it with following default link.
http://192.168.0.1
or
http://192.168.1.1
If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it.
Then it ask for user name and password.
Type user as "admin" and password as "admin" or "password" or blank.
Then you can see configuration page of router.
Click on WAN settings and set those settings as your internet service provider settings.
Enable DHCP if you want to get ip from router.
Click on wireless settings enable wireless then enable WEP Security then add WEP code .It is your password to connect wi fi.Then save settings and restart router.
Then you can connect your wi fi network with that code.

Let me know if you need further assistance.
Thanks for using FixYa.

you said every thing that connects with the ethernet is working. that means the wired part of the router is working. check the wireless settings of the router. Open the set up page of the router on the main computer. connect the main computer to the router with the ethernet cable.
change the wireless settings of the router.
WRT400N is a dual band router ( 2.4 GHZ and 5 GHZ)
You can create 2 different wireless networks. Make sure that the names (SSID) will be different for both the networks. For 2.4 GHZ change the standard channel to 6 and save the settings.
Go to wireless security and set the security mode to WPA Personal. set up password for the wireless network. You can use the same password for both the networks. Make sure that the Wireless MAC address is disabled.
Now try to connect to the new wireless network. and see what happens.
Click here for more information about routers

here is the link to the user manual ...if you changed the admin password and cannot get in you will have to reset the router and put all new settings back in

the default user name is : wrt400 or wrt400n
and default password is admin
To access the web-based utility, launch the web browser on
your computer, and enter the Router’s default IP address,
192.168.1.1 or http://wrt400n.com in the Address field.
Then, press Enter.
A password request screen will appear. (Non-Windows XP
users will see a similar screen.) Leave the User name field
blank. The first time you open the web-based utility, use
the default password admin. (You can set a new password
on the Administration > Management screen.) Click OK to
continue.

As long as you have a 802.11n wireless card, all you should have to do is setup the router and configure your network. Enable WPA2 encryption to ensure maximum performance of -N
If you don't have a 802.11N wireless card yet, then that is an upgrade I would suggest.

My friend, current technology does not allow for these speeds via wireless. Wire is rated at 100 (cat 5) or 1000 (cat 6) while wireless is 10. Your Linksys will communicate with your modem device at the higher rate, but the wireless will be slower.

To get the 1000 speed, all devices attached to your 1000 rated network will have to be rated 1000; computers, printers, routers, etc. You must also use category 6 or higher cable to get that speed. If you have any device on a 1000 rated network that is rated at a slower speed, everything will slow down to that slower speed.

I am not a wireless fan for two reasons: (1) Speed (2) security. Normally, distance is not a problem - Current technology allows for a 300 foot radius circle around your router (perfect circumstances)

Now then, the salesman may tell you something else and there may be another question catcher come in and tell you something else. My comments are based on my own personal experience while operating my own networks.
