    Please specify your internet connection type, as well as the router model number (wrtg4g, etc). The router settings will be different depending on your connection

Go to your desktop and login to the router, the manual should have the default ip and username/password, or google that info, once your in check the number of dhcp leases and make sure it is set to about 2 more than the number of PC's you have, I have a problem with mine like this because i always forget to count for the devices on my network that arent actually PC's and of course the nintendo wii takes an ip as well, then go to the wireless settings, make sure wireless is enabled the channel is set to 6 or higher to reduce interference, 11 is usually the best choice. then head to the wireless security tab, make sure it is all off for now, if your router has SES do not press the cisco logo button on the front of it I recommend not using the SES(its easy setup for wireless security). once this is done grab the laptop, i would recommend bringing to near the desktop and router all in one room if possible, now the operating system on the laptop becomes important, hopefully you have xp and not vista, for many reasons,  first you want to try refreshing your ip. you will need to go to the start menu then to control panel, then switch to classic view, this will make finding things a lot easier, then look for network connections. inside the network connections control panel you should see some items like local area connection and local area connection 2, one of those is your wireless card, generally it will be number 2 but that is not always the case. right click on it and then from the context menu select repair, it may take a minute but then it may be working afterward, if not then try opening  the wireless card connection (double click) then click on the properties button then in the new window double click tcp/ip settings another new windows should appear, it should have radio buttons marked that say obtain ip address automatically and another that says obtain dns auto.... this would normally be just fine try changing to a static address, the use the following address option, now you need to come up with an ip yourself, here how that works... find the default ip of the router, it is the default gateway to the pc, it will probably be something like so you want to keep that address scheme( you absolutely have to, an IP address is like a mailing address, if its not right then you'll never get any communications through) so your  laptops IP should be something like note in this case that the 192.168.1. part must stay in this ip( its a class c) the last section can be anything other than the router, which will either be .1 or .254 unless you changed it or the default is something else which it usually isnt. the subnet mask should end up try using tab to skip it and windows may just set it for you, the default gateway is the routers address, for dns it can be left blank or add the router ip as the preferred, then click ok on the last two windows and close on the status windows, try the connection again, if the problem continues go back to the network connection control panel and do another repair and try again, if it still doesn't work try setting the radio buttons back to automatically get an ip and automatically discover dns server, then go to the start menu and then run and type cmd, a command prompt will open, type ipconfig /release then hit enter and when that finishes type ipconfig /renew then hit enter and it should attempt to get an ip, should be working after all that, sorry it seems so long and complicated after you set a few of these up it becomes almost second nature. it looks and sounds harder than it really is, just read everything carefully and take your time, don't mean to sound condescending or anything but a lot of people who say they aren't any good with computers is usually because they are impatient and expect the machine to know what they want it to do without reading what it displays or even trying to understand what the computer is doing. good job on buying linksys though, its about the best brand for home networking equipment. also to make refreshing your ip easier you can make a bat file containing the following text:
@echo off ipconfig pause ipconfig /release ipconfig /renew ipconfig pause
hope this helps , good luck

Wireless Connection Problem

The wireless card didn't get a IP address from the router when it booted up.
Right click on the wireless icon and then click on Repair.
This will force the wireless card to get a new IP address from the wireless router.

Linksys router will not work with my hp deskto

you will need to "set up" the router.
This is the support page for linksys, if you enter your model in the drop down box, you may see a "Easy Setup' or "assistant" software to help set it up, otherwise you can contact your ISP and they will walk you through entering the right settings.
You will usually have to enter, or something close in the address bar when you hook your router up and get pagecannot be displayed, type in that number (or the correct ip of the router) and it will get you to the router setup page.

Speeding up internet

Here are a few suggestions on how to speed connection:

- Move router or pc location if possible. Closer = better connection usually

- Try changing the channel your router is broadcasting on. Sometimes there are slower channels and faster channels in heavy traffic area

- If you have any toolbars in your browser (i.e., yahoo or google), remove them. Those toolbars use up resources that can slow you down.

- Delete cookies and internet files

If these don't work, post a comment on here with your operating systems on laptop and desktop and router type.

Hi Ive connected my linksys wrt 54g working fine on main puter but can't connect on my laptop .It's showing strong reception but then says cannot connect,Thanks,Guy

Check in the router settings, in your internet browser from your deskyop, type and enter the router config screen by using a blank username, and admin for a password. Look through the settings and make sure it is set to wireless signal on. Also, look to make sure your laptop isn't made specifically for Wireless N technology. Some wireless adapters aren't backwards compatable.

Wireless g wrt54g router

First of all, are you connecting with a PC or a Notebook?

If you have the Linksys router, you should replace the MS utility with the Linksys utility it figures your linksys wireless lan card
There are programs you can use to keep track of your router and connections...One such program is called Port Mapper...

Does your problem happen everday...or every 3 weeks...are you doing anything in particular when you are getting the inability to use the connection?
There is a new Vista patch out there I recommend downloading.
