I have a linksys wrt54GX2 wireless G router and I would like to use it as an access point to pick up our internet signal from downstairs. The modem in use is wireless motorola SBG900. I have a desktop and a laptop, in which the desktop is connected wirelessly. How can I set up the linksys as an access point to better the signal of the wireless modem downstairs?

With the Linksys router it is not possible. You will need to connect the cable between the two routers. Linksys router will not pick up the wireless signal from the other wireless router.
May be it will work If you upgrade the DD-WRT Firmware. Not sure but it may. consult with the DD-WRT expert before upgrading the firmware.

You have two ways on how you can get other computer online through this router. First, you can wired them (using an Ethernet cable) to one of the Ethernet ports on the back of the router. They are the ones labeled 1, 2, 3, and 4.

Second is through wireless, but those computers that will connect through wireless must also have a wireless adapter to be able to pick up the signal that this router is broadcasting.

If you have concrete floor slabs the the wireless signal from the Linksys will have a difficult time penetrating the floor slabs.
The wireless card in the computers will show a low signal strength.
Try altering the Linksys aerial to a horizontal position and also positioning the Linksys to another location.

You could be getting interference form other wireless sources, check the wireless channels of other wireless router/access points in your area. If they are broadcasting on the same channel then configure your Linksys to broadcast on an unused channel or one that has the weakest signal strength.
If none of these methods work then I would suggest you run network cables from the Linksys to upstairs and downstairs and not use the wireless connection.
If network cabling option is not an option then consider extending the wireless range with wireless repeater access points.

if you want for mobile than contact customer service gprs connection and save the connection for the phone Bhoshdina

Many DSL modems need to be set into a 'bridged mode' when connected to a router. A call to Verizon customer tech support should be able to walk you through it as long as they supplied the modem. If not, and you do not have any documentation from your modem, go to the manufacturer's website and I am sure they will have a step by step. I hope that helps.

• Is your computer connected to the wireless router
• If you are able to see the router, maybe you need a security code to access it.
• disable and enable your wireless on your computer.
  

Do hope 1 of the above helps.

Try to upgrade the firmware of the router.Download firmware file from http://www.linksysbycisco.com/US/en/support for your model and open 192.168.1.1 Leave username blank and in password type admin click on administration and then on firmware upgrade.Browse and select the downloaded file and upgrade the firmware.

it might be because of interference...no issues dont worry about that...

JUst follow these steps and the issue will be resolved....

1,connect the blue cable between the computer and the router(any 1 of the 4 ports in the

router)

2,connect the other Ethernet cable between the Modem(came from ur internet people) and the

Router's Internet port(standalone port at the back of the router)

3,In the rear panel of the router u can see the reset button.with the help of the paper or

ball point pen,press it hardly and hold it for 1 minute..

4,Now turn off ur modem and the router..wait for other 1 minute..

5,turn onn only the modem first and wait till all the lights lit.now turn on the router and wait

till the power light is solid..open the internet Explorer it should work..

u will be connected to the internet..

The same happened to me, I just unplugged the router and plug it again, and i got internet access.

Ok, so why do you need an access point upstairs and a router downstairs connected wirelessly? If you can't connect with a laptop or a pc, why whould you think you could connect the access point? The purpose of this configuration would have to be with the access point to the router via ethernet. What's the point? If the problem is range, check out http://www.dd-wrt.com/dd-wrtv2/index.php to enhance the capabilities of the WRT54G... and maybe building a parabolic antenna for it as well. Plans to do so abound at Lifehacker.com.
