My router routes to my laptop within my house and

WNDR3400 is a dual band WiFi router.
In case your Laptop has Wireless N card then you can can use Wireless N on WiFi else you need to use Wireless G.To enhance the Router performance Disable one WiFi Network on your Router(Either N or G) and configure Channel 11 for long range signals.
To configure said changed you need to login into Router (http://192.168.1.1 or http://10.0.0.1)Check IP address to find your router's IP address (Gateway address is the router address)Type User name and passwordDefault username and password for netgear routersUsername : admin Password : password
Goto wireless settings and disable one of the wireless network a per your requirements (N 0r G, if you have Wireless G adapter on your laptop then suggest you not to use Wireless N)Changed Channel - 11
Save settingsAnd reboot Router
Hope this helps

With that particular model you wont be able to use it as a wireless bridge. You can however run an ethernet cable from the modem to any point in your house. the SBG900 i believe has wireless built into it, so you may need up with 2 wireless networks.

Hope that helps.

Some routers just don't put out strong signals. The problems could be wiring in/around/at your house or neighbors....causing weak signal. Are the signal strengths strong in your house?

We have super signal strength on ours upstairs (we have a bi-level house) but downstairs the signal is very low. All the wiring in the house and anything electronic or otherwise can block it.

Hope this helps at least some. Good luck!

Suggestion: Move your router. Your PC 3 appears to be in a 'dead zone' so to speak.

If your router has the external antenna the signal will increase when you point the antenna in the direction where the computer is used the most. It always helps to locate the router in a central area and on the upper floors of a house because the broadcast signal falls like rain. Another trick to try is to change your broadcast channel in the router, the normal default is channel 6. Each channel broadcasts at a slightly different frequency. Hope this helps...Tennis123

Can you check if your laptop will still be able to get online if its in the same location where the non working wireless computer is?

laptops have a wide range reciever built around the screen and tend to be far better than a normal usb dongle.

The fact that your pc is downstairs will be effected a lot because the signals from the router will be bouncing around in an area around the antenna and above, signals below will be effected by floors, doors and wall partitions.

Your best solution would be to place the router on a phone line downstairs and see if the signal is increased.

I suggest that you move the router around to find the strongest signal for you computer or if your computer has a small antennae try moving that fround for the best signal

for your signal to be stronger,you need to change your power settings on you router.by default it is set to 4. try a higher number.this will allow your signal to reach further.

my router power is set to 4 right now(this keeps my signal in the house only), but if if i want to take my notebook outside of the house, i have to set a higher power setting.

You need to buy a modem booster or a acces point to boost the signal of your router .
