Question about Linksys WRT400N Router

I just bought a Linksys WRT400N Router and need to know if there is anything I need to do to my computer for preparation before I install. I have a working Motorola WR540G router now but want to upgrade to N wireless versus G.?

    I am assuming this N wireless card you refer to is inside my computer i am installing the new router

    on. if this is indeed the case then how do I find out which wireless card it has? If it turns out I do not

    have N then what do I need to do?

  • Robert DeBerry Feb 07, 2010

    I am pretty sure it is a Dell 4400 and is probably 5+ years old or older.

  • Robert DeBerry Feb 07, 2010

    You stated "if I am connecting wireless to the desktop" and this is confusing to me, especially since

    I only know enough about this stuff to be really dangerous but aren't I just connecting wireless with my laptop by receiving the internet signal thru the new router? I am not sure what my desktop has to do with it?

  • Robert DeBerry Feb 07, 2010

    Sorry, you are right. It is indeed the Dimension 4400 "desktop". I withdraw my last stupid post.

  • Robert DeBerry Feb 07, 2010

    My laptop is a Dell Precision M90. It has a Dell wireless 1490 dual band WLAN mini-card.

    It also shows a Broadcom NetXtreme 57XX Gigabit Controller showing under Network Adapter in the

    device manager.

  • Robert DeBerry Feb 07, 2010

    do you think one would be better over the other?. I'm sure I would probably have to have someone install the new internal card for me and also there would be new drivers needed for that card, am I correct? It appears the dongle would be easier but not sure it would be the better of the two.

  • Robert DeBerry Feb 07, 2010

    also I forgot to ask how much signal you are getting with the dongle and I knoew this depends how

    far away you are and how many walss,etc it has to go thru......?

  • Robert DeBerry Feb 08, 2010

    Sounds great. I agree with you. I went ahead and ordered 2 of the dongle from Newegg yesterday.

    I will attempt to run both my laptops wirelessly off of those. Do you think I need to wait until I have

    the USB dongle before I attempt to install my router or is it okay to go ahead and install.?

  • Robert DeBerry Feb 09, 2010

    I also am using my router to connect wirelessly to XBOX 360 live and I found out yesterday that the

    wireless adapter that attaches to the XBOX 360 is only able to connect up to G and not N.

    So my question is, will the XBOX 360 still be able to connect to the NEW router I install by being backwards compatible or am I out of luck on this.....?

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.

    You can check the system specifications that came with the computer.


    You can also check device manager, for the model wireless card, and check the specs of that card. If the Card is not -N capable, you can buy a replacement card. If you post the brand and model of the system, I can give you a recommendation on an upgrade is needed.

  • IQUIT Feb 07, 2010

    If you are connecting wireless to the desktop, then you will likely need to upgrade the card.

  • IQUIT Feb 07, 2010

    You stated a Dell 4400 (I was assuming Dimension 4400 desktop) is the laptop a M4400 precision workstation? I'm not getting a clear picture of the computer systems you are using. Could you give me some details?

  • IQUIT Feb 07, 2010

    Now, on you laptop, it you tell the brand/model of the wireless card in it (Shown in Device Manager) then I can let ya know if it is N capable

  • IQUIT Feb 07, 2010

    The 1490 is 802.11 a/b/g if you want to connect at -N speed, you'll need an upgrade on the wireless


    You can buy a -N internal card to replace the 1490 like this:


    http://cgi.ebay.com/Dell-M1330-Wireless-...


    or a USB -N device like I did with this one


    http://www.newegg.com/Product/Product.as...



  • IQUIT Feb 08, 2010

    The USB one is easier, and they work about the same. I personally couldn't justify paying 4 times as much for a updated internal card when I can get a USB one, that works just as well.


    I have the Rosewill one I linked, works fine

  • IQUIT Feb 09, 2010

    Go ahead

  • IQUIT Feb 09, 2010

    it is backwards compatible

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!

How do I reset my Linksys WRT400N Router to factory defaults


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

the defaults from Administration > Factory
Defaults in the Router's web-based utility.

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.

What is a WEP key for a Linksys WRT400N wireless router?


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.

Wrt400n connects via ethernet cable, but won't talk wireless


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.

I reset the WRT400N password, then entered the default password admin and it does not work


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.
